PART THREE
THE TRANSCENDENTAL ELEMENTS
OF KANT'S SYSTEM
by Stephen Palmquist (stevepq@hkbu.edu.hk)
Reason's nature is
such that it can never conceive anything except insofar as the latter is
determined under given conditions. Consequently, inasmuch as it can neither
rest with the conditioned nor make the unconditioned comprehensible, nothing
remains for it, when thirst for knowledge invites it to grasp the absolute
totality of all conditions, but to turn back from objects to itself in order to
investigate and determine the ultimate boundary of the capacity given it,
instead of investigating and determining the ultimate boundary of things.
[Kt3:564-5]
Kant's System of Theoretical Perspectives
When one has
thought according to a method and then expressed this method and distinctly
stated the transition from one proposition to the next, then one has treated a
cognition systematically. [Kt10:148(149)]
1.
The Four Stages of Representation in General
The
task set before us here in Part Three is to fill the formal structure of Kant's
architectonic, as outlined in III.3-4, with the content provided in the part of
each Critique called the
Transcendental Doctrine of Elements.[1] This will
require us to put forward a more detailed interpretation of Kant's Critical
philosophy, beginning in this chapter with his system of theoretical perspectives
(as developed mainly in Kt1). One of the risks of modulating from formal to
transcendental logic in this way will be that of oversimplification-i.e., of
making distinct what Kant (perhaps purposefully) left obscure, or vice versa.
Consequently, I shall not pretend to have discovered texts in Kant's writings
which match perfectly with each of the twelve formal components in Figure
III.6, nor to have accounted adequately for all of his multitude of apparently
technical terms. Instead, I shall pick out those arguments which seem to
constitute the essential elements of his system (and which must therefore, in
the case of Kt1, be common to both editions [see note I.21]), in hopes of determining
the extent to which each can be correlated with one of the components given in
Figure III.6. (The goal of such a procedure is to develop a schematic outline
of systemt which can be used as a map to guide us through Kant's text, and which
can therefore simplify the task of those who wish to reformulate Kant's
arguments in contemporary terms [see I.1].) Such correlations are not always as
straightforward as we might wish, so in some cases they must be advanced
tentatively, as the best choice presented in the text. Nevertheless, I believe
the correspondence between the elements Kant put forward and the twelvefold
pattern described in III.3 is sufficiently close to establish my claim that he
was working towards such an ideal pattern, but was unable to elaborate its
structure precisely enough in his own mind to pass it on unambiguously to his
reader [see Kt1:862-3].
As
suggested in III.4, the form of my interpretation of systemt will be as
follows. Its four major 'stages' are concerned with the analysis of the nature
of sensibility [VII.2.A], understanding [VII.2.B], judgment [VII.3.A] and
reason [VII.3.B]. Each stage has three 'steps', arranged in a synthetic pattern.
Thus, I will interpret Kant's presentation of the 'conditions of knowing' in
systemt as containing a total of twelve steps. Each step is itself established
as necessary by means of a threefold (synthetic) argument. The various 'elements'
which operate in each step of Kant's overall argument (and which, taken
together, constitute the 'Doctrine of
Elements') can therefore be regarded as constituting a ninefold pattern in each
stage. The formal structure of such 'second-level synthetic integration' is
discussed in Pq18:4.1, but does not need to be described here. Instead, a very
general, but also very important, example will be used to demonstrate the
threefold structure of each step in Kant's presentation. Once this is done, we
will discuss the general character of each of the four stages in systemt and their
structural relationship. These two introductory tasks will prepare us for a
detailed study of each stage.
As
we saw in VI.2, Kant's whole theory of the synthetic progression of the
elements of knowledge is based on the assumption that the knowing subject must
'represent' to itself an unknown thing in the form of a 'representation'. The
power to perform this function is attributed to the 'faculty' of
representation. Two ambiguities concerning this claim, which could give rise to
much confusion and hamper our understanding of almost every step in systemt, are discussed
in Appendix VII.A.
An
examination of representation makes a good introduction to Kant's way of
arguing not only because it reveals these typical ambiguities, but also because
he uses the term in connection with almost every step in his theory [cf.
Kt1:94,376-7]. Representation itself 'cannot be explained at all', since it
'would have to be explained again through another representation': human
knowledge 'always presupposes representation' [Kt10:34(38)]. 'All representations',
he insists, 'can themselves become objects of other representations'
[Kt1:A108]. So his entire discussion of the conditions of knowing can be regarded
as an account of the faculty of representation applying a series of conditions
(+) to the object which is to be conditioned (-), so that the latter is
represented in a more and more determinate form of representation (x), until
all such steps eventually lead to the fully determined knowledge of the represented
object. The format chosen to summarize this most general function of knowing
can therefore be adopted as the pattern for summarizing the steps in each of
Kant's systems.[2] The synthetic
structure of this basic argument can be depicted straightforwardly by using the
following schema:
Kant
defines an 'organism' in Kt7:376 as 'an organized natural product in which
every part is reciprocally both end and means.' Taking this comment, together
with his subsequent claim that the interrelationships between the parts of an
organism are 'founded upon ... the causality of an architectonic understanding'
[388-9], to apply not only to physical organisms, but to rational systems as
well (as he suggests in Kt1:xxii,xxxvii-xxxviii), can help us to understand the
formal relationship between each of his twelve successive threefold arguments
(or steps). Following the format given above, the first part of each step will
specify the material given, i.e., the conditioned element (-), which is carried
over from the conclusion of the previous step; the second part will specify the
formal function, i.e., the condition (+), which is supplied by the subjective
faculty involved;[3] and the third
part will specify the synthetic unity (x) of these, thus yielding a new level
in the determination of the object. The 'end' of each argument (i.e., the
third part) is then presented to the 'means' (i.e., the second part) of the
next step: that is, the object at this new level of determination serves as the
material for the next step; and the process continues until the object is
finally represented as fully determined. Such reciprocal development is what
Kant means by 'the causality of an architectonic understanding'. Kant alludes
to this synthetic pattern when he notes that a transcendental argument is
required whenever 'an a priori determination
is synthetically added to the concept of a thing' [Kt1:286]. But even though
the Critical philosopher is concerned primarily with the transcendental aspects
of the elements defined by each argument, Kant often discusses their empirical
aspects as well. I shall mention this empirical side of many of the arguments
discussed, but concentrate mainly on their transcendental character (using
'transcendental' here in the broad sense in which all the conditions of knowing,
regardless of the stage in which they arise, are transcendental [see II.4,
III.4 and IV.2].
Two
methodological clarifications must be made before we discuss the structural
relationship between the four stages of systemt. The first is
simply that its twelve progressive steps must be taken to determine only the
transcendental-logical order of the
elements which constitute experience, and not the empirical-temporal order in which they are
experienced.[4] But the second
is rather more complex: ignoring the fact that Kant is interested more in the
formal conditions of knowing[5] than in actual
experienced knowledge could lead an interpreter to confuse the synthetic method, which analyzes how empirical
knowledge is possible [see Ap. IV and Kt2:276n], with actual 'synthetic a
priori knowledge' as such. Inasmuch
as we can discover the twelve conditions of knowing only through
transcendental reflection on the way in which empirical knowledge arises,
Kant's synthetic method in Kt1 can be thought of as an analysis of the elements of such knowledge, organized according to
the (architectonic) form of their logical synthetic progression [see F1:114-6].
Once it is taken as given that we know
something, any investigation of that knowledge will be analytic; but such an
investigation can be presented in a synthetic form by theoretically putting
all empirical knowledge in abeyance and asking what syntheses logically gave
rise to the possibility for analysis.[6] Thus, although
the series of arguments which constitutes the synthetic method will reveal at
some point the content of some synthetic a priori knowledge, it will also
reveal other types of knowledge [see Figure IV.2]; for the series itself is
intended to trace all the conditions
which, when regarded as syntheses from the Transcendental Perspective, explain
the possibility of the empirical knowledge being analyzed.
The
first and second stages of systemt deal with the faculties of
sensibility and understanding. Kant describes the functions of these 'two
sources of representation' [Kt1:327] in the Transcendental Aesthetic[7] and in the (Transcendental)
Analytic of Concepts,[8] respectively. He
defines sensibility as 'the capacity (receptivity) for receiving
representations through the mode in which we are affected by objects' [Kt1:33;
cf. 75 and Kt6:211n]. In other words, 'the senses' are 'the first foundation of
all judgments' [Kt18:361(102)], so that the aim of the first stage is to discover
how the material for knowledge (i.e., sensation) arises through the function
of intuition. Special attention is paid to the role of 'representations which
are not empirical' [Kt1:A99]; thus the faculty of sensibility adopts the transcendental perspective in systemt.[9] However, Kant
defines understanding in a number of different ways. Indeed, he assigns to
'understanding' almost as wide a variety of possible meanings as he does to
'representation'. So it is important to determine which of his meanings applies
to the second stage of systemt and how the understanding
in this sense is related to sensibility.
'Understanding is, to use general terms, the faculty of knowledge' [Kt1: 137]. As
such, it is 'the mind's power of producing representations from itself, the spontaneity of knowledge' [75]. Kant
analyzes this general meaning in Kt66:138(19):
understanding (in the most
general sense of the term) ... must include: 1) the power of apprehending given
[representations] to produce intuition ..., 2) the power of abstracting what is
common to several of these to produce a concept ..., and 3) the power of
reflecting to produce knowledge of the object.
As we shall see, this threefold division of
the general powers of the understanding directly corresponds to the first
three stages of systemt (i.e., to intuitive sensibility, conceptual
understanding and determinate judgment, respectively). But Kant later distinguishes this general type of
understanding from sensibility by calling the former 'the higher cognitive
power' and the latter 'the lower'. He then specifies that, as 'the higher
cognitive power', the faculty of understanding 'consists in understanding, judgment, and reason'
[196-7 (68-9); s.a. Kt7i:201 and Kt39:476(182)]. And these three terms refer directly
to the second, third and fourth stages of knowing (i.e., to conceptual understanding,
determinate judgment and inferential reason, respectively). In its most general
sense, therefore, the understanding is equally well describable 'as a spontaneity
of knowledge ..., as a power of thought, as a faculty of concepts, or again of
judgments', as a 'faculty of rules' and as 'the lawgiver of nature' [Kt1:A126];
indeed, it is involved in some sense in every
stage of knowing, so that, as Beck says in a note to Kt4:9, it is itself 'the
faculty of empirical knowledge'.
The
terms sensibility, judgment, and reason all refer in their own right to stages
in systemt, so the sense of 'understanding' we shall adopt-that is, as referring
to the second stage-will be its narrow sense, according to which it refers to
one aspect of the higher cognitive power in general. Kant uses the word in this
sense when he says 'the understanding ... thinks only, and does not intuit'
[Kt1:139]. But within this specific usage, the word 'understanding' is
occasionally utilized even more specifically as a description of any one of the
three functions which combine to make up the second stage [e.g., 134n]. Fully
aware of its multifarious meaning, Kant observes that 'the proper task of a
transcendental philosophy' is the 'dissection
of the faculty of the understanding itself, in order to investigate the
possibility of concepts a priori'
[90-1]. Rather than discussing every variation at this point, let us now
examine the relationship between understanding and sensibility.
As
the second stage of knowing, understanding is always closely related to
sensibility. In fact, Kant himself speculates that these 'two stems of human
knowledge' may 'spring from a common, but to us unknown, root' [Kt1:29].
Whereas sensibility provides the transcendental
material for empirical knowledge, understanding in the second stage
provides 'the logical form of all
judgments' by forming self-conscious thoughts which correspond to sensations
[Kt1:140e.a.; s.a. 143]. Understanding in this context is therefore always conceptual understanding. Like
sensibility, understanding is an abstract function, in the sense that it is
concerned not with concrete objects of real experience, but with one aspect
of our knowledge of such objects in isolation from the other. The faculty of
sensibility considers intuition in abstraction from the corresponding power,
which I shall call 'conception' [see note VII.28], and is always 'passive,
consisting in receptivity'; the faculty of understanding, by contrast,
considers conception in abstraction from intuition and is 'active and manifests
power' [Kt66:140(21)]. This relation
of passive to active, or matter to form, suggests the former can be correlated
with - and the latter with + [see III.4].
The third and fourth stages of systemt deal with the
faculties of judgment and reason, and are presented in the Analytic of
Principles and in the Dialectic, respectively. Kant defines judgment as 'the
mediate knowledge of an object, that is, the representation of a representation
of it' [Kt1:93]: it is the empirical realization of the understanding in its
concrete relation to sensibility. Thus, the role of the third stage in
clarifying how judgments are possible can be depicted as a simple synthetic
integration, as shown in Figure VII.1. 'The judgment indicates what use is to
be made of the understanding.'[10] For, as Kant
says in Kt7:407: 'understanding must wait for the subsumption of
Understanding (+)
Figure VII.1:
The 'Lower' Cognitive Powers as a 1LSR
the empirical intuition ... under the
conception, to furnish the determination [of an empirical object] for the
faculty of judgment.'
Kant
defines reason in a deceptively similar way, as 'the faculty of inferring, i.e., judging mediately' [Kt1:386; s.a.
Kt14:59(93)]. Rational inference, or 'syllogism',[11] refers to the subjective
function whereby certain universal conditions are determined to apply to an
object of judgment which cannot be discovered through judgment alone
[Kt1:360-1]. 'Concepts of understanding', he explains, 'first provide the
material for making inferences' [366-7]; judgment, which now 'mediates between
the other two faculties' [Kt7i:202], serves as the form (+) under which such
conceptual material (-) is subsumed in order to be synthesized in an inference
(x) [Kt1:360-1]. Thus, for Kant 'a syllogism shows in its conclusion something
more than the activity of the understanding and judgment required by the
premises, viz., a further particular
activity belonging to reason' [K2:345(Z1:112)]. The synthetic relation between
these three higher stages is depicted in Figure VII.2. Kant summarizes the
synthetic relation between these three faculties in Kt39:472(171): 'Under-
Figure VII.2:
The 'Higher' Cognitive Powers as a 1LSR
standing is the knowledge of the universal.
Judgment is the application of the universal to the particular. Reason is the
faculty of perceiving the union of the universal with the particular.'
Because
the role of sensibility drops out in this fourth stage [Kt1:363; cf. R11:65],
inferential reason, as we shall see, often tends to be employed speculatively.
This occurs when the understanding adopts sensibility's transcendental
perspective, rather than the logical or empirical perspectives which properly
belong to it; as Kant puts it in Kt1:345, 'employing the understanding
transcendentally' is 'contrary to its vocation'. But in their proper employment,
the objects ultimately determined through inference 'serve only for the
completion of reason's empirical perspective' [Kt1:593; cf. 714]-i.e., only to
complete our systematic understanding of the nature of empirical objects. As we
shall see in VIII.3.B and Appendix IX, the fourth stage in each of Kant's
systems functions in this same way, revealing the ultimate fulfillment or purpose of what might already seem to be
complete at the end of stage three.
The
most comprehensive way of mapping the stages of systemt, however, is
not to isolate sets of three which form simple syntheses, but rather to include
the relations between all four, in the form of a 2LAR.[12] By doing so, the
four stages in systemt can be correlated on a one-to-one basis with the
four perspectives mapped onto Figure IV.2. Each of these perspectives has as
its task the defense of one type of synthetic a priori (and in this broader
sense, transcendental) condition for knowing, as shown in the following table:
Table VII.1: Basic Perspectival Relations in Systemt
Each of the conditions of knowing (i.e.,
'transcendental forms') listed above serves as the formal element in its respective stage, so in each case it will appear
as the second step in that stage [see III.4 and Kt19:389-92]. The focal point in each stage, therefore,
will be the task of determining rationally 'how an empty form acquires the content which fills it', rather than merely
observing empirically (as in a non-Copernican philosophy, such as
Aristotle's) 'how a given content
acquires its form' [G10:92n]. When that content fills the form, the empirical
goal of the stage is reached, just as in the example of representation, given
above. This means each stage will start with a kind of transcendental 'object'
(or matter), proceed from there to a transcendental 'subject' (or form), and
conclude with an empirical synthesis of the preceding two elements.
One
way of mapping these stages onto the cross is to regard them as arising out of
two 1LARs: between the axes,
representing the receptive (-) faculties of intuitive sensibility and
determinate judgment and the spontaneous (+) faculties of conceptual
understanding and inferential reason; and between the end points of each axis, representing the abstract (-) faculties of
sensibility and understanding and the concrete (+) faculties of judgment and
reason. This gives us the model shown in Figure VII.3.
We can now see that the synthetic relation
mapped in Figure VII.1 attended only to the first term in the two-term
components describing sensibility and understanding. Likewise, Figure VII.2
made use only of the second term in the corresponding two-term components
specified in Figure VII.3. Moreover, the close affinity, as well as the marked
distinction, Kant saw between the Analytic of Concepts (conceptual
understanding) and the Analytic of Principles (determinate judgment) [see note
VII.8] is reflected by the fact that these two stages are represented in Figure
VII.3 by the two secondary, or mixed components, while stages one and four are
represented by the two pri-
Figure VII.3: The Four Stages in Systemt
mary, or pure components. (Kant's important distinction
between the 'logical' and 'real' employments of the understanding refers to
the contradictory, i.e., +- vs. -+, relation between these two stages.)
Keeping
in mind this description of the formal relations between the four main stages
of systemt will help us to steer a straight course through the rough waters of
Kant's terminology. In VII.2 we will examine the six steps which constitute the
first two stages of this system, the stages dealing with intuition and
conception in abstraction from each other; and in VII.3 we will examine the
third and fourth stages, which deal with our concrete judgment and reasoning
concerning real objects of empirical knowledge. Once this arduous task is
completed, we will be in a position in VII.4 to look back over our exposition
in order to determine the extent to which the interpretive tools given in Parts
One and Two have enabled us to discern order in the actual content of systemt.
2.
The Abstract Conditions of Knowing (-)
A. Intuitive Sensibility (--)
Kant's
exceedingly broad understanding of terms such as 'representation' and
'understanding' makes it necessary for him to introduce other terms to describe
both the objective and the subjective elements which operate at each particular
step of systemt. Since we have already considered at length in Part Two several of the
most important of these more specific terms, I will assume with only brief
reminders that their meanings are already sufficiently understood. Two such
terms come up in the first step of Kant's twelvefold progression.
We
saw in VI.2 that 'thing in itself' is a label for that aspect of an object of
knowledge which transcends our modes of representation, and is therefore
unknowable [s.a. Ap. V]. Since it does not have the status of a formal condition
of knowledge [see notes VI.12,17], it cannot be correlated with any of the
components listed in Table III.5 (though we can label it with a neutral
component, 0). When considered as determined only to the extent of being
represented by a subject through an 'original' act of representation, the thing
in itself can be called the 'transcendental object'.[13] This first
representation of reality in the form of an undetermined object is entirely
negative with respect to our knowledge, so it is appropriate that this
material (-) step in the sensibility (--) stage is correlated with the purely
negative component, ---.[14]
Although
he uses phrases such as 'original representation' and 'immediate
representation' only occasionally [e.g., Kt1:40,41], Kant seems to regard this
condition as a necessary starting point. For he frequently uses 'original' in
close proximity to 'representation', usually when referring to the original
(i.e., non-empirical [Kt1:72]) representations of space [40] and time [48], in
contrast to the 'original apperception' in which the second stage culminates
[see e.g., A107]. He also speaks in Kt1:A99-100 of the 'original receptivity'
through which the representations of sensibility become possible. Here 'original'
indicates the bare fact that a thing must first of all be represented as an
object in order for us to know it empirically [33; s.a. W6:297]. Indeed, intuition
itself is 'possible only if the subject's faculty of representation is affected
by that object' [Kt1:72], yet this 'transcendental object remains unknown to
us' except, as we shall see, through the mediation of the 'forms of our sensible
intuition' [63]. Moreover, in Kt10:64(71) he calls representation 'the first
degree of cognition', thus suggesting its role as the first step in systemt. Using the
method suggested in VII.1, we can now summarize step one as:
The
next step maintains that the transcendental object must be represented as an
'appearance' through the process Kant calls 'intuition'. Once again, the
meaning of the third term of this argument was fully explained in VI.2, where
we referred to it, when viewed from the transcendental perspective of systemt (i.e.,
sensibility), as a 'transcendental appearance'; but the role of intuition as the 'form of appearances'
[Kt1:223; s.a. 323-4] has yet to be explained. This process of intuition is
neither an imaginative activity nor a capacity for 'mystical insight'
[R7:240-5], but the function whereby the undetermined object is interpreted by
the subject as a mass of unorganized representations called the 'manifold [Mannigfaltige]' (i.e., 'multiplicity' or
'variety'). Once the original given, the transcendental object, is intuited [Kt1:
A394], so that it has the formal (+) limits of sensibility (--) imposed upon
it, it becomes a manifold of appearances (--+) and can serve as 'the data for a
possible experience' [A119,298]. 'Possible experience' is Kant's way of
referring to immediate experience [see IV.1] as viewed from the theoretical
standpoint. But another formal limit, as we shall see, must be imposed by the
understanding in the second stage [A119] before the contents of this possible
experience can become 'data for a possible knowledge' [296]. Kant holds these
formal limits to be 'concepts which are of two quite different kinds ...,
namely, the concepts of space and time as forms of sensibility, and the categories
as concepts of understanding' [118]. The former, as given here in stage one,
are the source of our immediate 'awareness of individual entities', while the
latter, to be given in stage two, are the source of our awareness of their
general nature, as mediated through thinking.[15]
The
manifold of appearances is sensible only when it appears in the context of
space and/or time-i.e., only when these intuitive 'forms of sensibility'
[Kt1:522] are applied to it. (Since this is 'the only kind of intuition we possess'
[302], Kant calls a (transcendental) appearance 'the undetermined object of an
empirical [or 'sensible'] intuition' [34].) Kant says: 'The faculty of sensible
intuition is strictly only a receptivity, a capacity of being affected in a
certain manner with representations, the relation of which to one another is a
pure intuition of space and time' [522]. Thus time and space, the two pure
forms of all human intuition, 'come before appearances and before all data of
experience, and are indeed what make the latter at all possible.'[16]
Kant
proposes two ways in which this sensible intuition can be manifested in the
human subject: through 'inner sense' (i.e., the soul) and through 'outer sense'
(i.e., the body).[17] He proposes:
Space is nothing but the form
of all appearances of outer sense. It is the subjective condition of
sensibility [Kt1:42].
Time is nothing but the form
of inner sense, that is, of the intuition of ourselves and of our inner state
[49].
Time is the formal a priori condition of all appearances
whatsoever [50].
This means all objects which appear to the
inner sense-i.e., 'the sum of all representations' [220]-are intuited in the
context of time, while both time and space are required for an object to appear
to outer sense.[18] 'Time and space,
taken together, are the pure forms of all sensible intuition, and so are what
make a priori synthetic propositions
possible' [55-6].
Because
the pure intuitions of time and space are not forms 'inhering in things in
themselves as their intrinsic property' [Kt1:45], but exist 'only in us',[19] they cannot
claim 'absolute reality'.[20] As Kant
explains, 'these a priori sources of
knowledge, being merely conditions of our sensibility, just by this very fact
determine their own limits, namely, that they apply to objects only in so far
as objects are viewed as appearances, and do not present things as they are in
themselves' [56; cf. A9:320]. This limiting function explains why such
spatio-temporal intuition is the core element in the transcendental perspective of systemt. Pure
spatio-temporal intuition fulfills the transcendental function of enabling the
representations of the first step, which could otherwise be regarded only in
terms of the transcendental object, to be represented as a manifold of appearances
here in the second step. That is:
This
second condition not only determines the intuitive form of sensibility, but also enables the matter provided by the transcendental object to be revealed in the
appearances; for as Kant says, 'appearances contain in addition to intuition
the matter for some object in general [i.e., for the transcendental object]'
[Kt1:207]. The third condition of sensibility (--), therefore, must be to
actualize these formal (+) and material (-) conditions in a synthetic unity
(x); that is, the appearances, or sensible
intuitions must actually be sensed,
thus representing the manifold of appearances as a discrete sensation.[21] This process
can be summarized as:
Kant
does not devote much attention to this third step in his argument, perhaps
because its conclusion is so obvious.[22] It is important
to point out, however, that the sensations in this third step, as viewed here
from the transcendental perspective, are not sensations as we actually
experience them, but refer only to the level of determination of the object
produced by the faculty of sensation in abstraction from the understanding.
(Kant does sometimes view sensibility empirically, in an active sense-as, for
example, when he says 'inner sense presents to me ...' [Kt1:321]. But when
viewed transcendentally, sensibility is the purely passive capacity for
receiving objects, some of which will eventually help constitute knowledge.)
This third step completes the sensibility stage of systemt and establishes
sensation as 'the material of sensible knowledge'.[23] Of course, those
sensations which are never conceptualized in such a way as to produce possible
knowledge will never become conscious [C1:1.352-5]. Inasmuch as unconscious
sensations are not epistemologically interesting, Kant ignores them and
concentrates instead on those destined to help make up empirical knowledge
[Kt1:A111].
B. Conceptual Understanding (+-)
As
mentioned in VII.1, the aim of the understanding in the second stage is to
provide the abstract conceptual form for the abstract matter presented to it by
sensibility. This does not mean 'All
intuitional process is conceptually controlled' [E3:89e.a.], but that in order
to produce empirical knowledge, such
material processes must submit to the formal 'control' of conceptual processes.
In Kt1:A94 Kant lists three 'conditions for the possibility of experience',
which must hold true in order for thoughts to arise out of a manifold of
appearances : '(1) the synopsis of
the manifold a priori through sense;
(2) the synthesis of the manifold
through imagination; finally (3) the unity
of this synthesis through original apperception' [s.a. 104,A115]. He then reminds
us that the Aesthetic (i.e., the first stage) culminates in the first of these
conditions, sensation [A94-5]. The second stage, as expounded in the Analytic
of Concepts, now assumes the logical
perspective (+-), which culminates in the formation of self-conscious thought;
therefore, the other two conditions listed in Kt1:A94 should function as two of
the steps in this second stage.
Kant's
account of the fourth step of systemt is somewhat
muddled by his use of several terms in very similar ways with no clear
explanation of their relationship. In particular, the terms 'imagination',
'perception' and 'apprehension' are easily confused, because they all take
part in the function of synthesis,
which Kant regards as the 'first application' of the understanding to
sensibility [Kt1:152], and which he defines as 'the act of putting different
representations together, and of grasping what is manifold in them in one [act
of] knowledge.... Synthesis of a manifold ... is what first gives rise to knowledge'
[103]. 'The understanding does not', according to Kant, 'find in inner sense
such a combination of the manifold, but produces
it, in that it affects that sense.'[24] This 'synthetic
influence of the understanding upon inner sense' is what Kant ordinarily refers
to as 'the transcendental act of imagination' [154]. In itself, apart from the
illumination provided by the fifth and sixth conditions as they 'bring this
synthesis to concepts', the
imagination is 'a blind but indispensable function of the soul, without which
we should have no knowledge whatsoever, but of which we are scarcely ever
conscious' [103]; it simply 'connects the manifold of sensible intuition'
[164] in such a way as to form an inner image of the sensations involved.[25]
This
application of imagination to sensations results in a conscious 'association of representations',[26] which Kant calls
perception [Kt1:160,164]. Perception
is the act in which appearances are 'combined with consciousness' [A119-20]
to produce 'objects of perception' [207]; it 'contains sensation' as its
'matter' [208-9]. Accordingly, a perception can be described as a 'representation
accompanied by sensation' [147], as long as it is a 'sensation of which we are
conscious' [272]. In short: 'Perception is ... a consciousness in which
sensation is to be found' [207; cf. Kt22:217]. Since this consciousness, which
forms sensations into perceptions, arises only through the synthesis of
imagination, 'perception' can be thought of as a general description of the
whole process (i.e., the four steps) leading up to and including this
synthesis. Kant suggests this when he describes the entire second stage as that
in which 'our faculty of knowledge ... advances from particular perceptions to
universal concepts' [Kt1:118; cf. Kt7i:203n]. As the material (-) step in the
second stage (+-), perceptions can therefore be correlated with the +--
component in Figure III.6 [s.a. Table III.5].
An
accurate summary of the complexities of this fourth condition would have to
take into account Kant's variety of expression [see Ap. VII.E], which would be
too cumbersome for our purposes. Instead, we need only express the essential
function of this 'first principle of the human understanding' [Kt1: 139; s.a.
152] in stage two:
No matter which terms we use to describe it,
this fourth step serves, by means of a transcendental synthesis, to 'bring the
manifold of intuition on the one side into connection with the condition of the
necessary unity of pure apperception on the other' [Kt1:A124; s.a.164].
Apperception,
however, does not follow synthesis immediately in systemt (i.e., it does
not function as the form to be imposed upon the perceptions represented in
the material step); rather this function is fulfilled by the 'pure concepts of
the understanding' (i.e., the 'categories')
[see e.g., Kt1:A119], while apperception, as we shall see, acts as the
synthetic condition of stage two.[27] For 'our
understanding ... can produce a priori unity
of apperception solely by means of
the categories' [145e.a.]; indeed, such 'transcendental unity ... is thought in
the categories' [151]. The categories, as 'the conditions of the necessary
unity of apperception', and not apperception itself, can be regarded therefore
as doing for stage two what 'the formal conditions of space and time' do for
stage one [A110e.a.; s.a. A111,136]. Whereas 'the categories contain, from the
perspective of the understanding, the grounds of the possibility of all
experience in general' [167], space and time contain the grounds for the same
possibility, from the perspective of sensibility. Since Kant believes 'All
synthesis ... is subject to the categories' [161], he describes the latter as
categories of synthesis, to which the
object as given in step four, that is 'perception, must completely conform'
[162], and which as such prepare the way for the unity of apperception in step
six. 'Consequently, all possible perceptions ... must be subject to the
categories' [164-5].
Whereas
the second condition of the first stage gave rise to objects of intuition (i.e., appearances), that of
the second stage gives rise to objects of thought or conception (i.e., concepts). Kant defines thought rather loosely as
'knowledge by means of concepts' [Kt1:94], but more precisely as 'the act which
relates given intuition to an object' [304]. In Kt1:A124 he explains that
'concepts ... are brought into play through the relation of the manifold to the
unity of apperception', thus implying that they arise out of the application
of categories to conscious perceptions here in step five. The connection
between the concepts produced by this activity of 'categorial conception'[28] and the
categories through which this task is achieved is frequently made explicit, as
when Kant refers to the categories as 'forms of thought' [e.g., 150, 289,305]
(as opposed to space and time as 'forms of intuition'[29]), or as 'the
pure form of the conceptual perspective on objects in general' [305]. As such,
categories are 'concepts of objects in general' [K2:11.301(Z1:183); s.a. Kt1:
158], which suggests a correlation between the intuitive determination of the
transcendental object in stage one and its conceptual manifestation in stage
two [see Ap. VII.B]. Since the categories function as 'the law of the synthetic
unity of all appearances' [A128], a concept produced by such conception 'is
always, as regards its form, something universal which serves as a rule.'[30]
Kant
often stresses the necessary, reciprocal relationship between intuition and
conception: 'Now there are two conditions under which alone the knowledge of an
object is possible, first, intuition,
through which it is given, though only as appearance; secondly, concept[ion], through which an object is
thought corresponding to this intuition' [Kt1:125; see also Kt69:325; K2:
11.302(Z1:184)]. Just as intuitions are intelligible only when related to concepts,
so also concepts are objectively valid only if they are related to intuitions
via perception [Kt1:272]. Even though in experience these two are always
combined, Kant believes that, by theoretically abstracting from the particular
content of all perceptions and examining their general content [A245], he can compile a complete list of all the a
priori categories of pure understanding.[31] Moreover, as we
saw in III.3, there is a sense in which the twelve categories correspond
directly to the twelve steps in systemt-a correspondence
which Kant himself begins to elaborate in Kt1:742-3 when he says quantities
(--) can be 'exhibited a priori in
intuition', while qualities (+-) can be known 'only through concepts'. In any
case, our need to abstract from
experience in order to arrive at the categories [Kt1:165] does not contradict
the fact that they function in systemt as 'independent
cognitive acts' [R11:89]. For as Wallace says: 'The pure or abstract categories
have their home in logic' [W5:171]-i.e., in the logical perspective of systemt. So we can summarize
the general function[32] of this formal
(+) step in the logical perspective (+-) of systemt as:
Even
though Kant establishes the categories by abstracting all sensibility from
experience, he is careful to remind us that 'the categories, in themselves mere
forms of thought, obtain objective reality' only when they are applied 'to
objects which can be given us in intuition' [Kt1:150-1]. That is, since 'the
categories are not in themselves knowledge, but are mere forms of thought for the making of knowledge from given
intuitions', it follows that 'no synthetic proposition can be made from mere
categories' [288-9]-in themselves they define the formal character of the
logical perspective in systemt. So, although in the second
stage Kant occasionally exaggerates the certainty of his choice of categories,
he is careful to warn elsewhere that 'the pure category does not suffice for a
synthetic a priori principle' [304].
Categories enable us to know things 'only through their possible application
to empirical intuition' [147]-a
process which will not be fully explicated until the third stage.
In
the sixth step of systemt the faculty of 'transcendental apperception' synthesizes
the material perceptions (-) with the formal concepts (+) developed by the
understanding: only through a 'synthesis according to concepts' can
'apperception demonstrate a priori
its complete and necessary identity' [Kt1:A112]. Whereas categorial conception
functions as the 'form of thought'
(i.e., of stage two), the unity of apperception realizes the whole purpose of
the understanding in the second stage, so it 'constitutes the form of all knowledge of objects; through it the
manifold is thought as belonging to a single object' [A129e.a.]. Its function
as the synthetic step in this formal stage of systemt leads Kant to
characterize it as 'the radical faculty of all our knowledge' [A114]. Indeed,
he goes so far as to say: 'The principle of apperception is the highest
principle in the whole sphere of human knowledge' [135]; 'this faculty of
apperception is the understanding itself' [134n; s.a. A119 and W21: 145].
Kant
defines transcendental apperception as a 'pure original unchangeable consciousness'
[Kt1:A107], and as 'the thoroughgoing identity of the self in all possible
representations' [A116]. As Paton suggests, its original character indicates that 'the unity of objects is derivative'
[P2:2.71]. Indeed, from the theoretical standpoint of systemt, 'the original
synthetic unity of apperception' [Kt1:135] is 'the source of all combination [i.e., synthesis]' [154e.a.] and so 'lies
a priori at the foundation of
empirical consciousness' [220; s.a. A116]. The categories themselves are said
to impose 'synthetic unity' on the objects of perception, thus converting what
is varied and manifold into a more-or-less unified object (via the concept).
But the object is not fully unified until it is assimilated into one person's consciousness: 'it is only
because I ascribe all perceptions to one consciousness (original apperception)
that I can say of all perceptions that I am conscious of them' [A122].
Apperception is therefore the synthetic condition for determining the material
presented by the imagination's synthesis of the manifold, as well as the
concepts produced by the categories, to be elements in which I participate (i.e., self-conscious
thought).[33] Of course,
imagination might be able to synthesize, and the categories to conceptualize,
without ever arriving at the unity of apperception; but such a non-unified
combination of the manifold would be irrelevant to systemt, since it could
not give rise to empirical knowledge.
As
Bird points out, Kant relates transcendental apperception 'both to the notions
of a personal and a conceptual unity' [B20:115; s.a. 121,174,176]. The
conceptual unity is determined by the categories in step five. Apperception
unifies the twelve categories (and so also the structure of transcendental
logic itself [R11:10]) in a single, 'bare' or empty representation of the self
[Kt1:A117n], thereby allowing all the abstract thoughts which arise in step five to be united in the I think. (In this analytic sense
apperception can be regarded as 'the ground of the possibility of the
categories' [A401], for its I think
'accompanies all categories as their vehicle' [406].) The personal unity of
apperception, then, is 'the synthetic unity of appearances' which alone, Kant
argues, enables the manifold of appearances to become known as 'one experience' [281]. For it is the
unity 'to which everything that is to belong to my knowledge ... has to conform' [220e.a.]. 'The synthetic unity of
consciousness is, therefore, an objective condition ... under which every intuition
must stand in order to become an object
for me' [138]. In its most basic form, 'the consciousness of self' involved
here is revealed in 'the simple representation "I"' [68]. Kant
himself explains the nature and implications of the personal unity of
apperception with unusual clarity:
pure
apperception ... or, again, original
apperception ... is that self-consciousness which, while generating the
representation 'I think' ..., cannot
itself be accompanied by any further representation [132].
For through the 'I', as simple
representation, nothing manifold is given; only in intuition, which is distinct
from the 'I', can a manifold be given; and only through combination in one consciousness can it be thought [135].
An
important implication of the personal function of apperception is that in
itself 'the representation "I am" ... does not so include any knowledge of that subject', because it
'is not an intuition, but a merely intellectual
representation of the spontaneity of a thinking subject' [Kt1:277-8]. The
'I'-i.e., the concept of a conscious self-is supplied by a faculty of the
understanding (viz., apperception) rather than by sensibility, so empirical
knowledge of the self 'as it is in itself' is impossible [156]. For only that
which can be intuited in time and space is empirically knowable: 'The
determination of my existence can take place only in conformity with the form
of inner sense ... Accordingly I have no knowledge
of myself as I am but merely as I appear to myself' [157-8]. Therefore, through
the activity of 'the synthetic original unity of apperception, I am conscious
of myself, not as I appear to myself, nor as I am in myself, but only that I
am' [157].
But
Kant's immediate purpose in establishing the centrality of apperception is not
to explore its many implications for the concept of 'self'. For he treats this
subject more thoroughly in the Paralogisms section of the Dialectic. Rather,
his main reason for insisting at this midpoint of systemt that all the
previous steps must be united in one
person is to provide a firm basis for establishing empirical knowledge in
the third stage [A110]. In much the same way that sensation actualizes the
transcendental function of sensibility in the first stage, pure apperception
actualizes the logical function of the understanding [134n] in the second stage
(+-) by synthesizing the material (-) state of the object in step four
(perceptions) with its formal (+) determination in step five (concepts) in the
form of a unified network of self-conscious
thought (x) here in step six.[34] So we can
summarize the fulfillment of this final abstract condition for the possibility
of experience as:
With this sixth step, the second stage of
knowing is completed, thus bringing us to the midpoint of systemt.
The
first stage of knowing supplied the sensible material (--) for a possible experience. The second stage has now
informed us that 'the pure understanding, by means of categories, is a formal
and synthetic principle of all experience' [Kt1:A119]; as such it has supplied
the intelligible form (+-) for a possible knowledge.[35] Kant summarizes his
analysis of the first two stages of 'the act of knowing' in Kt7:238: 'a given
object [step one], through the intervention of sense [steps two and three],
sets the imagination at work in arranging the manifold [step four], and the
imagination, in turn, [sets at work] the understanding in giving this
arrangement the unity of concepts [steps five and six].' To complete systemt, these two
epistemological building-blocks must be synthesized (-+) in judgment; and the
resulting empirical knowledge must be grounded in the ultimate unity (++) of
the rational ideas. In the next section, we shall follow Kant's argument
through these two final stages.
3.
The Concrete Conditions of Knowing (+)
A. Determinate Judgment (-+)
A
source of possible confusion in interpreting the third and fourth stages of
systemt is that Kant sometimes seems to suggest that empirical knowledge has
already been actualized in the first two stages [e.g., Kt1:94,104; cf. W21:
159,227]. For example, he asserts: 'Intuitions and concepts constitute ... the
elements of all our knowledge' [Kt1:74]. But this does not mean the separate
functions of intuition and conception as such are sufficient to constitute empirical
knowledge, as some have assumed [see Ap. VII.H]. For he continues: 'These two
powers or capacities cannot exchange their functions. The understanding can
intuit nothing, the senses can think nothing. Only through their union can knowledge arise.'[36] Although there
is, as mentioned above, a sense in which the first stage supplies us with possible experience and the second with possible knowledge, the essential
Critical doctrine is that actual
empirical knowledge arises only in stage three, wherein the first two stages
are combined from the empirical perspective of determinate judgment.[37]
The
synthetic role of the third stage[38] in relation to
the first two implies that 'a third something is necessary' in order for an
object to be judged. This third thing, Kant says, is the 'possibility of experience'
[Kt1:194-5]. By this he means that the intuition and conception of an object
must be able to be synthesized in actual (determinate) experience. The object
can then be said to 'exist', as long as 'the perception can, if need be,
precede the concept' [272]. An object of thought can thus become empirically
known as an object of judgment only if it is possible for that object to be
given in intuition [146].
On
this basis we must qualify Kant's claim that thinking 'is the same as judging'
[Kt2:304; s.a. Kt1:106] before his intended meaning can be rendered
intelligible. Rather than regarding thought and judgment as strictly synonymous
terms, we should view judgment as thought which makes use (or at least can make use) of intuition. A clear
understanding of their perspectival relationship will guard against the
temptation to assume a strict 'identification of thinking and judging'
[H4:xlvi; see Ap. VII.H]. For the two faculties refer to different levels in
the determination of the object by the understanding: 'Now the only use which
the understanding can make of these concepts [i.e., those arising out of the logical perspective] is to judge by
means of them'; so from the empirical
perspective, 'we can reduce all acts of understanding to judgments, and the understanding [in its broad sense] may therefore be represented
as a faculty of judgment.'[39]
Kant
concisely summarizes the first two steps of this third stage in Kt1: 175:
first, the schematism [176-86] 'will
treat of the sensible conditions under which alone pure concepts of understanding
can be employed' (-); and second, the principles
[187-294] 'will deal with the synthetic judgments which under these conditions
follow a priori from pure concepts of
understanding' (+). The third step,
though neglected by Kant in this preview of the content of the third stage, is
expounded just where we would expect to find it, in the third chapter of the Analytic of Principles [294-315]. By providing
'a summary' of the theory through the distinction between 'phenomena' and
'noumena' [295], this chapter explicates how the actual judgment of objects establishes objectively valid empirical
knowledge (x). As we shall see, the new terminology introduced in this ninth
step also points directly to the fourth stage.
Kant's
seventh condition of knowing, 'the schematism
of the pure understanding' [Kt1:179], specifies just how the categories are
applied 'to sensibility in general' [A245]. The second stage has already shown
that the categories stand in a necessary relation to sensibility, for the
former arise out of the abstraction of all spatial and temporal content from
the latter [Kt1:161-2; cf. P2:2.67-8]. But in order for these categories, and
the concepts they determine, to be used validly in experience, they must be
grounded in something concrete once again [171]. Consequently, the third
(synthetic) stage begins by positing something
which is homogeneous on the
one hand with the category, and on the other hand with the appearance, and
which thus makes the application of the former to the latter possible. This
mediating representation must be pure, that is, void of all empirical content,
and yet ... sensible. Such a
representation is the transcendental
schema [177].
Kant describes this first 'condition of
judgment (the schema)' [304] as that in which the object is determined to be a
'manifold and an order of its parts' [861]. To fulfill this function,
schematism must furnish abstract, self-conscious thought (step six) with the
transcendental unity of one time.[40]
Just
as he believed the transition from the first to the second stage to have been
accomplished by the transcendental imagination in the fourth step, so also Kant
bases the transition from the second to the third stage on the work of this
most mysterious of human powers here in the seventh step. He says, for
instance, that a 'schema is in itself always a product of imagination'
[Kt1:179]. As with the first application of imagination, he confesses he cannot
explain how it works, because
'schematism ... is an art concealed in the depths of the human soul, whose real
modes of activity nature is hardly likely ever to allow us to discover, and to
open to our gaze' [180-1]. But he does warn that the schema 'has to be
distinguished from the image', because, although it may be represented in an
image, it is fundamentally the 'representation of a universal procedure of imagination [viz.,
'schematism'] in providing an image for a concept'.[41]
Kant
summarizes the fourfold, categorial division of the schemata rather concisely
in Kt1:184-5, where he defines them as 'a
priori determinations of time in accordance with rules', and relates them
'in the order of the categories to the time-series,
the time-content, the time-order, and lastly to the scope of time in respect of all possible
objects'. By limiting the categories in these four ways, the schemata, each of
which is itself a 'sensible concept of an object in agreement with the
category' [186], insure that the abstract concepts of stage two 'are altogether
impossible, and can have no meaning, if no object is given for them' [178].
This means thoughts can never be more than subjectively valid if they do not
correspond to a possible object of outer intuition; for as Paton says in
P2:2.393, when an object is objectively valid, 'the matter of inner sense is
derived from outer sense.' Thus, the seventh step in systemt, expressed as
is the material beginning (-) of the synthetic
procedure of judgment (-+), whereby 'sensibility ... realises the understanding
in the very process of restricting it' [Kt1:187].
Once
schematism is shown to have secured the necessary relation between sensibility
and understanding, Kant turns his attention to what is often regarded as the
most important part of systemt: 'the judgments which understanding
... actually achieves a priori',
which he calls 'principles' [Kt1:177]. Although he is not entirely consistent
in his use of these terms, he ordinarily refers to the particular, empirical
laws of the understanding as 'rules' and reserves the word 'principle' for the
transcendental laws of judgment to which all rules must conform.[42] 'Principles a priori', he explains, 'are so named
not merely because they contain in themselves the grounds of other judgments,
but also because they are not themselves grounded in higher and more universal
modes of knowledge' [188]. However, Kant is not interested at this point in
every type of a priori principle. Inasmuch as the principles of mathematics,
for example, 'are derived solely from intuition, not from the pure concept of
understanding' [188], they do not qualify as principles of judgment. Similarly,
the analytic principles of formal logic can be excluded, because, as we shall
see, every principle of judgment must be synthetic.[43] But regardless
of which type of principle is under consideration, the schematism requires
that 'all principles ... have significance and validity only as principles
of the empirical, not of the transcendental, perspective' [223], and that as
such they will inevitably contain some non-pure elements [cf. IV.1 and
C14:253]. For 'outside the field of possible experience there can be no synthetic
a priori
principles' [Kt1:304-5].
The
principles whose functions Kant discloses in step eight are the formal
'conditions of the unity of empirical
knowledge in the synthesis of appearances'-i.e.,
in the synthesis of the third stage [see note VII.38]-which of course, 'can be
thought only in the schema'.[44] Since they
function as 'rules for the objective employment of the [categories]'
[Kt1:200], they can be completely revealed under four headings, each
corresponding to one category: the principles of quantity are 'axioms of
intuition', of quality are 'anticipations of perception', of relation are
'analogies of experience', and of modality are 'postulates of empirical
thought in general'.[45] As we saw in
III.3, Kant divides these four types of principles into two basic groups: mathematical principles are those
'involved in the a priori
determination of appearances according to the categories of quantity and
quality', and dynamical principles
are those correlated in a similar fashion to relation and modality [Kt1:200-1;
see Figure III.4]. The former deal with the synthesis of various homogeneous
aspects of an object and can be known with 'intuitive certainty', while the
latter deal with the synthesis of heterogeneous aspects and 'are capable only
of a merely discursive certainty.'[46]
A
detailed account of the nature and role of each of the twelve principles which
can be derived from the basic four is unnecessary here, since our primary
concern in this study is not with Kant's specific arguments [see I.1]. It will
suffice instead merely to state each of the main synthetic a priori propositions
which Kant believes he has shown to be necessarily constitutive of all
empirical objects. In the order of the categories, these principles are:
(1) Axioms: 'All intuitions
are extensive magnitudes' [Kt1:202].
(2) Anticipations:
'In all appearances, the real that is an object of sensation has intensive
magnitude, that is, a degree.'[47]
(3) Analogies:
'Experience is possible only through the representation of a necessary
connection of perceptions' [Kt1:218].
(a) Substance: 'In all
change of appearances substance is permanent' [224].
(b) Causality: 'All
alterations take place in conformity with the law of the connection of cause
and effect' [232].
(c) Reciprocity: 'All
substances, in so far as they can be perceived to coexist in space, are in
thoroughgoing reciprocity' [256].
(4) Postulates: (No general
principle specified).
(a) Possibility: 'That which
agrees with the formal conditions of experience ... is possible' [265].
(b) Actuality: 'That which
is bound up with the material conditions of experience ... is actual' [266].
(c) Necessity: 'That which in its connection with
the actual is determined in accordance with universal conditions of experience,
is ... necessary' [266].
Kant omits any mention of the three
derivative principles for the axioms and anticipations, as well as the general
principle for the postulates, though Paton suggests these gaps can be filled
easily enough [P2:2.64-5; but cf. M3:76-7]. In any case, Kant's neglect is not
detrimental to the unity of the system itself, since the function of step
eight is clear whether or not its own architectonic structure as a 12CR is
fully described.
The
key element supplied by the principles is the determination of an outer context into which the inner representation of the object as
schematized (step seven) can be placed. Just as the form of time was
reintroduced in step seven, so also the form of space is reintroduced here in
step eight, so that at this point 'intuitions ... are in all cases outer intuitions'.[48] Establishing
that, if the object is to be empirically knowable, it must be represented in
terms of the formal conditions of quantity (extensive magnitude) and quality
(intensive magnitude), and that it must stand in a possible, actual, and
necessary relation to the subject, is, no doubt, an indispensable part of this
task; but outweighing all of these is the task of establishing that the object
must be represented as a permanent substance which is both cause and effect in
a reciprocally interdependent nexus of substances. It is for this reason that
the analogies, whose purpose is to 'declare that all appearances lie, and must lie, in one nature' [Kt1:263], occupy well over half of the space Kant
devotes to the proof of the principles.
Taken
together, the four principles provide 'the ground of experience itself, and
therefore precede it a priori'
[Kt1:241]; for their application requires us to assume that our representations
have a certain 'relation to an [empirical] object', through which they 'acquire
objective meaning' [242]. As such, this eighth step provides the transcendental foundation for all
scientific, empirical investigation (i.e., empirical investigation which aims
at knowledge): 'We can extract clear concepts
of [the principles] from experience, only because we have put them into
experience, and because experience is thus itself brought about only by their
means.'[49] This formal
function (+) of the empirical perspective (-+) of systemt can be summarized
accordingly:
Kant's
final task here in the third stage of his argument is to clarify the sense in
which our time-schematized principles are actually employed in the production
of empirical knowledge [cf. B20:152]. The synthesis of an object's inner
determination in time (-) via schematism, and its outer determination in space
(+) via application of the principles, constitutes 'an empirical judgment'
(x) [Kt1:246]-i.e., an item of empirical knowledge. (Since this is Kant's
system of theoretical perspectives,
he sometimes refers to this as 'theoretical knowledge' [e.g., Kt7:195], a term
we can treat as synonymous with 'empirical knowledge'.) The ninth condition of
knowing is that such knowledge (x) arises only when an empirical object
actually conforms to a person's determinate judgment (-+) that it is
empirically real. This step can
therefore be summarized quite simply as:
However, Kant is often less than clear about
how this function actually operates. He suggests at one point, for instance,
that 'judgment is a peculiar talent which can be practised only, and cannot be
taught', and that 'the one great benefit of examples' is that they sharpen the
judgment [172-3]. Fortunately, he does occasionally offer a more precise
explanation of his intended meaning.
Kant
defines judgment as 'the faculty ... of distinguishing whether something does
or does not stand under a given rule' [Kt1:171]. From the empirical
perspective, all the judgments which result can be called 'rules' [304]; even
the principles themselves are rules insofar as they are manifested in real
judgments [Kt2:305]. But in its transcendental use as one of the twelve steps
in systemt, 'judgment' refers to the act of using
the principles to determine an objectively valid relation between two
representations: Kant gives the example of combining the representations
'body' and 'heavy' in the judgment 'The body is heavy'. The word 'is' in such a
proposition expresses the primary role of judgment, which is to bring 'given
items of knowledge ... to the objective unity of apperception', and thus 'to
distinguish the objective unity of [such] representations from the subjective'
[Kt1:141-2]. This means the objects of knowledge are no longer regarded as
being merely in the subject, as they
were in the first two stages, but are now acknowledged also to have an
independent reality of their own; for their representations are 'combined in
the object, no matter what the state
of the subject may be'.[50]
But
this claim on behalf of judgment raises a problem which is not easily solved:
If representations exist only in the subject, and if the object (i.e., the
thing) cannot be known it itself, then how can we know that two representations are actually united in the thing
represented, or indeed, that they would always be so united for any subject? In hopes of reaching a
convincing answer to this question here at the end of the third stage of his
synthetic progression, Kant takes a new look at the first stage in light of
what has now been revealed in the second and third. It is here that he
introduces his now famous (or infamous) distinction between noumena and
phenomena.
The
terms 'noumenon' and 'phenomenon' have been discussed at length in VI.3, where
they were clearly differentiated from terms such as 'thing in itself' and
'appearance', which, as we saw in VII.2.A, relate mainly to the first stage of
systemt. Kant's official introduction of the new 'object-terms' here in the
third stage is intended to summarize the theory as it now stands by pointing
up the difference in the perspective from which the object is viewed in the
first and third stages, and in so doing to prepare the way for the fourth and
final stage of his theory. The clarification achieved by the new terms can be
evinced by revising the foregoing account of steps eight and nine.
The
phenomenon, as we saw in VI.3, is the empirical object viewed from the
empirical perspective (-+). We can now see that the phenomenon first comes to
be determined as such through the formal, determining function of the
principles (+) in step eight. We can therefore revise our summary of the eighth
condition accordingly:
This modification stresses that the object,
which is determined to be an object by the principles (and the objective
reality of which is to be determined through judgment in step nine), is not a
thing in itself, but only a phenomenon represented in outer sense as an
object in space. A thorough investigation of the function of the principles
(especially that of substance, in which all the others are rooted) would be necessary
before we could fully understand just how Kant thinks they can fulfill their
task of determining an appearance to be a phenomenon [Kt2:304]. But such a
detailed treatment would be an unnecessary digression from our general line
of inquiry. Instead, assuming that they do, in fact, succeed in their
function, we will focus our attention on the main function of the
phenomenon-noumenon distinction, which is to shed light on the ninth condition
and its relation to the fourth stage.
As
we concluded towards the end of VI.3, our judgment of a thing to be
'objectively real' from the empirical perspective depends on the extent to
which we can validly represent it as a 'negative noumenon'. Just what this
'mark of independence' is, however, is
not altogether clear. It has to do with abstracting the conditions (and the
resulting material) of sensibility from the object just enough to judge whether
it can be conceived to exist independently of the subject. Accordingly, in the
process of realizing the goal of the empirical perspective (-+) in stage
three, the synthetic (x) function of judgment also determines how the object,
as a real item of empirical knowledge, will be presented to the fourth and
final stage-i.e., its noumenal character is at this point judged to be either
positive or negative. The former will give rise to a speculative perspective, and the latter to a hypothetical perspective, in stage four [see IV.3]. This revised
form of the ninth step can be summarized as:
As such, judgment prepares the way for the
fourth stage, where the object is released from sensibility and treated, so
far as is possible, as a noumenon. That is why Kant begins the Dialectic by reminding
us 'truth or illusion is not in the object, in so far as it is intuited, but in
the judgment about it' [Kt1:350].
One
of the main uses to which Kant puts his distinction between phenomena and
noumena is to emphasize that the understanding can produce valid empirical
knowledge only when it is applied
within the phenomenal realm, the realm of 'possible experience' [see note
VII.37]. The importance of this maxim for systemt can scarcely be
overemphasized, since the 'possibility of experience' not only makes possible
our ordinary a posteriori knowledge of the world, but also 'gives objective
reality [in the transcendental sense-see note VII.3] to all our a priori modes of knowledge.'[51] This unifying
function of experience was depicted in IV.4 by placing it in the center of the
map of Kant's four main perspectives in Figure IV.2. For experience itself
(i.e., as immediate) is not one of
the twelve conditions of knowing; it is, as it were, the 'hub' around which
all the formal conditions must revolve in order for us to know an object. We
have seen that sensibility views the object transcendentally as it appears (stage one), and understanding
views it as it is, either logically,
in abstraction from sensibility (stage two), or empirically, in synthetic
union with sensibility (stage three). Our only remaining task in interpreting
systemt, therefore, is to consider the fourth stage, in which Kant explains
how reason views the object hypothetically, as it may be.
B. Inferential Reason (++)
Both
the subject-matter and the organization of Kant's Dialectic in Kt1 [349-732]
tend to obscure rather than illuminate the nature of its role in presenting
the fourth stage of systemt. For, although it occupies far more space than the
sections which describe each of the other three stages [see Table VI.1], the
Dialectic concentrates comparatively less than the others on expounding the
relevant steps in the synthetic progression of the formal conditions of
knowing. Instead, that which is only a secondary task in the other
sections-namely, the specification and discussion of various philosophical
implications of the revolutionary aspects of the theory-becomes Kant's primary
task in the Dialectic. This, of course, is a change Kant has to make in order
to prove the inadequacy of traditional rational metaphysics. But as a result
many commentators ignore the fact that the theory he affirms in place of
traditional metaphysics is an integral part of systemt [but see E3:116
and IV.3]. They tend to detach the Dialectic from the rest of Kt1 as if it
could do just as well standing on its own as a self-sufficient set of
arguments. But, because our interest here in Chapter VII is limited to the
essential content of that portion of the Doctrine of Elements which evinces the
architectonic form of Kant's theory of knowing, we shall ignore the main part
of the Dialectic, Book II [Kt1:396-670], where Kant exposes and dispels the
illusory 'dialectical inferences' which uncritical human reason naturally
tends to make;[52] we shall focus
instead on Book I [349-96] and the Appendix [670-732], where Kant offers his
own alternative to the former.
The
goal of reason in the fourth stage is to complete what remains incomplete in
step nine-i.e., to determine, as far as is possible, the noumenal basis of
phenomenal objects. Given the fact that stage three judges all objects of
knowledge to have some sort of noumenal character (i.e., either negative or
positive), the fourth stage is not just an optional extra, added to fulfill the
requirements of the architectonic, or to pose some philosophically interesting
points about the nature of human reason; on the contrary, it is the final set
of conditions without which our empirical knowledge would risk losing its objective
reality. The function which fulfills this task Kant calls 'inference'; and, as
we might expect, it is itself the result of a three step process. Thus, here
in the fourth stage we become conscious of existence 'mediately through
inferences which connect something with perception' [Kt1:629]. (Concluding
systemt with inferential reason is rather appropriate, since the German word
for inference (Schluss) also means
'conclusion' or 'end' [but see note VII.11].) As Kant explains in Kt14:58(92),
'a distinct concept is possible only
by means of a judgment, a complete concept only by means of an inference.'
The
problem inherited by the fourth stage from the third is that 'no experience
[i.e., object of empirical knowledge] is unconditioned' [Kt1:383]; yet the very
judgment which yields empirical knowledge depends on our ability to determine
an object's participation in some sort of unconditioned (noumenal) reality. So
the first task of reason in the fourth stage is to 'prescribe to the
understanding [regarded as judgment (step nine)] its direction towards a
certain unity ... in such a manner as to unite all the acts of the
understanding, in respect of every [empirical] object, into an absolute whole' [383]. The abstract
representation involved in establishing the unifying 'direction' of reason in
its relation to phenomenal objects is what Kant calls 'a schema' of reason
[698]. Just as the schema of understanding
(step seven) requires concepts (step six) to be applied only in the field of
experience, so also the schema of reason
(step ten) requires ideas (see step eleven) to perform their unifying function
only 'from reason's world-perspective' [726]-i.e., only in relation to real objects of judgment (step nine).
The
object as determined by the schematism of reason here in the tenth step acts as
the material element (-) for the fourth stage (++); Kant calls it 'the
unconditioned'.[53] The object as
unconditioned is that 'to which reason leads
in its inferences from experience,
and in accordance with which it estimates and gauges the degree of its
empirical employment, but which is never itself a member of the empirical
synthesis' [Kt1:367-8]. The tenth condition of knowing can therefore be
summarized as follows:
Kant asserts that this activity of finding
'for the conditioned knowledge obtained through the understanding the
unconditioned whereby its unity is brought to completion' is 'a principle of
pure reason [which] is obviously synthetic;
the condition is analytically related to some condition but not to the
unconditioned.'[54]
Positing
the object as unconditioned in step ten does not in itself establish the
ultimate unity of all empirical knowledge; for the unconditioned object 'can
never come before us, since it cannot be given through any possible
experience.'[55] As a result,
reason must exert its unifying influence on the unconditioned in much the same
way as the faculty of understanding does (by means of the categories) on the
perceptions of the second stage and as the faculty of judgment does (by means
of the principles) in the third stage [378,383,692-3]. This means the
schematism of reason must construct its object 'in accordance with the
conditions of the greatest possible unity of reason' [698]. Such unity is 'not
the unity of a possible experience ..., which is that of understanding' [363];
rather it is 'an a priori [read: 'analytic'-cf. 358 and IV.3] unity by means of concepts', imposed directly
on the understanding [359; cf. 392]. Reason in this step establishes itself as
'the faculty of principles' [356]: 'Knowledge from principles is, therefore,
that knowledge alone in which I apprehend the particular [an a posteriori
fact] in the universal through [analytically related] concepts' [357].
The 'pure concepts of reason' which produce this rational unity
when applied to the unconditioned object are called 'transcendental ideas'
[Kt1:378]. Kant explains that 'the idea is posited only as being the
perspective from which alone [the unity of reason] ... can be further extended'
[709]; it is the concept of an object which 'transcends the possibility of
experience' [377]-i.e., 'a necessary concept of reason to which no
corresponding object can be given in sense-experience' [383]. 'Just as the
understanding unifies the manifold in the object by means of concepts, so also
reason unifies the manifold of concepts by means of ideas ...'.[56] These 'concepts
derived from pure reason', Kant insists, 'cannot be obtained by mere [i.e.,
empirical] reflection without inference.'[57] Hence 'it is a
necessary maxim of reason to proceed always in accordance with such ideas'
[699]; for this procedure of using ideas to infer the systematic unity of
reason [394] provides the form (+) of stage four (++), which, when applied to
the object as unconditioned, brings us one step closer to the ultimate
unification of empirical knowledge.[58] This eleventh
step can be summarized as:
Each
member of Kant's favorite trio of metaphysical concepts (God, freedom and
immortality [see X.1-2]) is represented by one of the three primary ideas of reason:
the Paralogism of Pure Reason [Kt1:A341-A405,399-432] assesses the idea of the
soul (including immortality); the Antinomy
of Pure Reason [432-595] assesses the idea of the world (including freedom); and the Ideal of Pure Reason [595-670]
assesses the idea of God.[59] Each of these
has a legitimate employment, but tends to be used to draw 'pseudo-rational' conclusions
[397]. As mentioned above, we shall omit from this chapter any detailed
discussion of these ideas. The three chapters in Part Four correspond, in
reverse order, to these three ideas. So it will suffice at this point to note
that they can be used to construct either a legitimate or an illegitimate
version of the twelfth and final condition of knowing. Both versions are
concerned with realizing the object which is represented in an idea by
actually reasoning as to its
validity. The difference between them arises 'not [from] the idea in itself,
but [from] its use only, [which] can be either transcendent or immanent' [671;
cf. 697-8].
The
transcendent, or 'constitutive' use of the inferred ideas is employed by those
who adopt the speculative perspective, and inevitably leads to metaphysical
illusion [Kt1:352-4,537; see IV.3]. Speculative metaphysicians mistakenly
take the judgment of the negatively noumenal character of the object in step
nine to be a positively noumenal judgment about the object as it is in itself.
As a result, they naturally assume 'that there is an actual object corresponding
to the idea' [510]. This 'objective employment of the pure concepts of reason
is ... always transcendent' [383];
for it attempts to establish rational principles 'which profess to pass beyond'
the 'limits of possible experience' [Kt1:352]. The goal of such 'speculative'
reasoning is 'the ascribing of objective reality to an idea that [properly]
serves merely as a rule' [537]. Establishing such objective reality in regard
to a transcendent object would yield synthetic a priori knowledge of reality
(i.e., of the positive noumenon) [see e.g., 386]. Such a 'representation of an
individual existence as adequate to an idea' can be called 'an ideal' [Kt7:232]. Thus we can summarize
this illusory version of step twelve as:
Kant
leaves no doubt that this use of the ideas invariably ends in failure: 'The
cause of failure we must seek [not in the unconditioned object, but] in our
idea itself. For so long as we obstinately persist in assuming that there is an
actual object corresponding to the idea, the problem [of establishing objective
knowledge of the object] ... allows of no solution' [Kt1:510]. At the root of
the problem raised by the speculative ideas lies a mistaken, transcendent use
of the categories:
once we recognize these
categories and their origin, merely as the form of thinking, we shall be
convinced that they do not by themselves provide genuine knowledge, and that,
when supplied with intuitions, they do not give us any supersensible theoretical knowledge, though they can
be used for practical ideas without
stepping outside their proper sphere. [K2:11.38-9(Z1:142, alt.)]
The
solution to this problem, then, can be found only by adopting a hypothetical
perspective, according to which the ideas are employed immanently in inference,
as regulative principles [see IV.3 and V.4]. Kant explains in Kt10:86-7(94)
that 'speculative cognitions ... [are] those from which no rules of behavior
can be derived ... [They] are always theoretical, but conversely, not every cognition
is speculative; viewed from another standpoint, it can at the same time be
practical.' The hypothetical perspective, which, as we have seen, is the
perspective in systemt which gives rise to the practical standpoint of
systemp, requires that the unconditioned object represented in the form of an
idea be 'viewed as if it were a real [object]' [Kt1:712; cf. 699] for the purposes
of empirical inquiry and systematic unity. But this use of an idea is 'valid
only in respect of our rational perspective
on the world':[60] 'For the
regulative law of systematic unity prescribes that we should study nature as if systematic and purposive unity,
combined with the greatest possible manifoldness, were everywhere to be met
with, in infinitum' [728]. This
activity differs from the speculative reification of the object inasmuch as it
is performed only hypothetically, without assuming that objectively valid
knowledge of transcendent reality can be established in this way.[61] All we can
legitimately do is to 'ascribe [to an idea], from the [hypothetical]
perspective of this unity, such properties as are analogous to the concepts
employed by the understanding in the empirical perspective' [705-6; cf.
D4:264-5]. (Examples of how this might be done will be explored in Pq20 [cf.
Ch. X].)
This
alternative perspective for step twelve accepts that an idea can be properly
applied only when the object in step nine is judged to have a negatively noumenal character. For 'the
idea instructs us only in regard to a certain unattainable completeness, and
so serves rather to limit the understanding than to extend it to new objects'
[Kt1:620]. Since the idea is now confined within such negatively noumenal
limits, its validity 'can be proved through experience' [830] by demonstrating
in hypothetical inferences how 'an actual case' [387] (a posteriori) is
subsumed (analytically) under the idea in question, even though 'the object of
[the idea] can never be given empirically' [390]. Far from having a mere
'"donkey's carrot" validity' [M2:248], Kant argues: 'The practical
idea is ... always in the highest degree fruitful, and from the perspective of
our actual activities is
indispensably necessary' [Kt1:385; s.a. 544-5]. The goal of hypothetical reasoning,
as the synthetic step (x) in the fourth stage (++), is therefore to establish
analytic a posteriori belief [cf. IV.3]. This legitimate version of the twelfth
condition, then, is:
Once philosophers accept that each of their
ideas must be regarded 'as an idea only and not as an entity', they will be
able to replace the old (supposedly synthetic a priori) 'Logic of Illusion'
with a new (analytic a posteriori) 'Logic of Regulative Principles' [R11:86].
For reason's entire pure endeavor has 'its source exclusively in the practical
interests of reason' [Kt1:825].
Imposing
the unity established by hypothetical reasoning in the fourth stage onto the
empirical objects of the third stage secures the objective reality of all
empirical knowledge. For in this final stage, we see how 'pure reason combines
all its epistemological perspectives into a system' [Kt1:394]. Although the
extent of an object's participation in the thing in itself is still unknown,
we have at this point established the conditions necessary for empirical knowledge to arise from the
theoretical standpoint. For the determination of the object has come full
circle: that which began merely as a transcendental object is now treated as
if it were subsumed under its unconditioned cause. The idea of the systematic
whole, of which each object of knowledge is a conditioned part, provides the
necessary context for objective theoretical knowledge-a context which could
not be provided by the unknowable thing in itself. The twelfth condition
therefore concludes not only the fourth stage, but the entire system of
theoretical perspectives. However, our interpretive task is not quite finished.
Lest we lose sight of our main purpose in sifting through the many details of
systemt, we must now summarize our findings and determine the extent to which
they accord with the formal model developed in III.3.
4.
An Analytic Summary and a Synthetic Model
By
asserting that all experience is dependent transcendentally on certain forms of
knowing, even though knowing is itself dependent empirically on the reality of
the things known [cf. Kt1:1], Kant maintained in systemt the a priori
centrality of the human mind while at the same time upholding the perspective
of ordinary human beings. The foregoing interpretation of this system has
followed the synthetic method of Kt1. But it may be helpful, now that the
conditions which determine our knowledge have been fully explicated, to
summarize systemt according to the analytic method, using the four
reflective perspectives discussed in IV.3 as an analytic framework. Listing
summaries of each of the twelve steps in reverse order, as in the following
four paragraphs, provides a concise, 'tabular' analysis of the elements of
Kant's system. (In a 'tabular' method, Kant notes in Kt10:149(149), 'an already
finished doctrinal edifice is presented in its entire context.') This will
enable us to diagram the relationships between each step [see Figure VII.4],
and in so doing to reveal 'the unity of the manifold modes of knowledge under
one idea'-viz., that of 'the form of a whole' [Kt1:860; cf. 673].
Stage four. The hypothetical
perspective (++) is concerned with viewing an experience (a posteriori) as if
it is contained (analytically) in a regulative idea of an unconditioned
object. Practical belief (x), the legitimate goal of reason's unifying
influence on experience, arises as a result of such hypothetical reasoning.
(Speculative reasoning, the illegitimate alternative to

THREE (-+) FOUR (++)
Figure VII.4: Schematic Analysis* of Systemt
hypothetical reasoning, is believed by
speculative metaphysicians to yield synthetic a priori knowledge through a direct apprehension of the unconditioned
object, by means of a constitutive idea.) The idea (+), which is the formal
aspect of inferring reason, provides a way of seeing the empirical world as a
rational unified whole; such unity is inferred to exist on the basis of an idea
of the whole. The material aspect (-) is the object as unconditioned (and thus,
as such, unknown), which itself arises out of the application of the schematism
of reason to items of empirical knowledge. In this way reason guides and limits
the understanding (stage two) in its formation of judgments (stage three).
Stage three. The empirical perspective
(-+) is concerned with the real objects (synthetic) presented to us in
experience (a posteriori). Empirical knowledge of an object (x) is attained by
judging its negatively noumenal (i.e., independently permanent) character.
(Speculative reasoning requires the object to be viewed here as a positive
noumenon.) Such a judgment is 'objectively valid' in virtue of its
conformity to the principles of pure understanding, through which the object
first comes to be determined as a phenomenon (+) in space and time. The
principles are applicable only to objects which have been schematized-i.e.,
only to those categorized appearances which have been synthesized according to
the imagination's inner determination of time. The schematized object (-) can
therefore be analyzed into its conceptual (stage two) and its intuitive (stage
one) components.
Stage two. The logical perspective (+-)
is concerned with the conceptual form (analytic) of an object as abstracted
completely from experience (a priori). Self-conscious thought (x) arises out of
the imposition of the bare 'I' (pure apperception) onto the various concepts a
person forms on the basis of his or her experience. These concepts (+) are
formed through categorial conception, in which pure categories are applied to
conscious perceptions (-). The latter, in turn, are produced as a result of the
imagination's transcendental synthesis of the sensations presented to it by
sensibility (stage one).
Stage one. The transcendental
perspective (--) concerns that which must hold true of an intuited object
(synthetic) before it can be processed (a priori) by the synthetic functions of
the understanding in stages two and three. The object at this point is
therefore merely a sensation (x), which is to say, it is a manifold of
appearances (+) received by the senses. An appearance is an object represented
to the inner and/or outer sense through the function of pure spatio-temporal
intuition. If it is an appearance of something real, it will be related in this
way to the transcendental object. The transcendental object (-) is the general
and totally undetermined original representation of the thing in itself. And
the thing in itself (0) is the unrepresented and thus unknowable form of an
object of experience, considered apart from the conditions which enable us to
experience it. We can have no knowledge of it, because there is no perspective
from which we can view it as such.
Having
now analytically summarized and diagrammed the interpretation of systemt put forward in
VII.2-3, we can assess the extent to which it corresponds to the ideal,
architectonic model constructed in III.3. The legitimacy of distinguishing
between the four main stages in systemt, and of relating
them according to the 2LAR pattern, seems to me to be beyond doubt. The account
of their relationships in III.4, IV.3 and VII.1 has, I hope, demonstrated this
with sufficient force. Since the first two terms in the components appended to
each of the summaries of the twelve steps refer solely to one of these stages, any doubt about my
interpretation or about the appropriateness of the component attached to any
particular condition must arise out of the way I have correlated the steps within each stage-i.e., out of the way
the third term in each component is
assigned. Now I freely admit there is plenty of room for debate concerning the
way I have applied the matter-form-synthesis pattern [see III.4] to the details
of Kant's text. The scarcity of textual evidence for the third step in some of
the stages (especially stage one) could be used to argue that there should
really be only two steps in each
stage, yielding a total of eight (though this would create quite a problem as
to how the synthetic (threefold)
character of Kant's method in Kt1 should be understood). Alternatively, one
could argue that 'form' should in each case precede 'matter', or that 'synthesis'
should precede both (in which case the components would be correlated in
different ways, but the whole would exhibit the same 4x3=12 pattern). Or
again, one could question whether such a clear-cut, 'sausage-factory' approach
to systemt does not misrepresent Kant's intentions: perhaps he intentionally presented the 'elements'
of each stage as blurring into each other, without ever wanting to suggest any
clear distinctions (though this would seem to contradict his emphasis on
architectonic neatness).
The
most such objections would require is relatively minor rearrangements in the
interpretation of systemt as I have presented it. One might remain unconvinced,
for example, by my arguments for associating the transcendental object with sensibility
rather than understanding, or for associating the imagination with the latter
instead of the former. To all such suggested revisions I would be open,
provided the proponent of such a change is able to collect sufficient textual
evidence for the alternative interpretation and is able to explain how the
texts I have used can be adapted to fit the alternative interpretation.
To
simplify the task of checking whether or not each element in my interpretation
is accurately described by the logical component assigned to it, I will review
briefly what the terms in each component represent. The first term in each
three-term component signifies that the element in question functions in a
receptive (-) or a spontaneous (+) stage: for this purpose, the stages directly
involving the elements of sensibility are receptive, while those which do not
are spontaneous. The second term in each component signifies that the element
in question functions in an abstract (-) or concrete (+) stage: the
perspectives concerned with isolating the fundamental constituents of empirical
knowledge contain abstract elements, whereas those requiring these constituents
to be combined in empirical knowledge contain concrete elements. The third
term in each component represents the material (-), formal (+) or synthetic (x)
function of the condition within its particular stage: the material condition
determines the bare necessities for an object to be viewed from a given
perspective; the formal condition determines the limits which define each
perspective; and the synthetic condition fulfills the purpose of its perspective
by uniting the material and formal conditions.
The schematic representation of systemt in Figure VII.4
might give the impression of being rather too rigid to represent accurately
Kant's intentions. For this reason we can supplement that analytic flowchart
with a synthetic model, using 'the circle of experience' [Kt1:8; cf. I.3 and
Figure III.6] to reflect the fact that in the text of Kt1 the twelve steps
tend to flow into each other in one continuous motion. Representing the
function of each step by a curved arrow and labelling the inside of each curve
with its corresponding roman numeral gives rise to the following model:
Figure VII.5: Kant's Circle of Experience
The four perspectives now correspond to the
four quadrants delineated by the axes
of a cross, rather than to their end
points, as in Figure IV.2. The outside of the diagram is labelled with
Kant's terms for the state of the determination of the object between each function.[62]
The
first and last points of the arc in Figure VII.5 are separated by a gap (thus converting
the circle to one cycle of a spiral) for several reasons. First, this gap can
represent Kant's contention that the original presupposition of the thing in
itself is not definitely confirmed to be an empirically
known object through hypothetical reasoning, but only to be a regulative idea of what it might be if
it could be represented in itself as an object. As such, the gap suggests
that, although systemt is theoretically complete (i.e., it has succeeded
in describing, from the theoretical standpoint, the nature and possibility of
empirical knowledge), it is teleologically incomplete (i.e., it fails to
provide an adequate basis for the reality of the objects to which its ideas
refer). Thus the gap shows that systemt points beyond
itself to some other standpoint, from which ideas of 'totality' (especially
Kant's three favorite metaphysical ideas [see X.1-2]) can be more firmly
grounded. In addition, this gap provides a way of representing the differences
between the hypothetical and speculative perspectives. The latter could be
represented by a slightly different kind of arc, which bends outward (towards
'ultimate reality') rather than inward (towards immediate experience [cf.
Figure IV.2 and IX.2]). Such a spiral would accord well with Kant's own
metaphorical description of speculative reasoning as an attempt to rise 'to
dizzy heights where [reason] finds itself entirely cut off from all possible
action in conformity with experience' [Kt1:717]. Whereas from the speculative
perspective knowledge of reality is regarded as ever transcending our experience of the thing in itself, from the
hypothetical perspective the thing in
itself is regarded as transcendent, and knowledge of reality is regarded as
legitimate only when it is directed towards experience.
These
two ways of positioning the gap in Figure VII.5 can also help to clarify
a possible ambiguity in labelling Kant's System 'Copernican': Copernicus'
astronomy takes humanity out of the
center of the universe, yet Kant's emphasis on the subject seems to do just the
opposite. However, Kant gives this impression only because of his bad habit of
occasionally exaggerating various claims. For his theory of the subject is, in
fact, intended to convey the notion that it is the subject's representational
determinations which separate the thing in itself from the objects of our
knowledge. And this role, far from contradicting Copernicus' principles,
establishes their philosophical equivalents as valid [see III.1]. For just as
the sun does not revolve around the earth, but vise versa, so also the subject
does not look directly out upon the thing in itself revolving around it (as
philosophers formerly assumed), but looks only inward, towards the 'earth' of
experience, while the transcendent 'gravitational fire' of the thing in itself
mysteriously holds everything together.
Numerous
ways of interrelating various combinations of steps could be discussed at this
point (indeed, almost ad infinitum!)-e.g.,
by connecting the twelve points in Figure VII.5 with three squares or with four
triangles [see Pq18:6.3-4]. (The formal similarities revealed in the former
case [see e.g., note VII.55] can also be seen in Figure VII.4 by reading down
each column rather than following the arrows across.) One such possibility
would be to relate the four main categories to the four main stages in systemt [cf. Figures
III.4 and VII.3]. Thus quantity might have some special association with
sensibility, quality with understanding, relation with judgment, and modality
with reason.[63] Similarly, the
twelvefold progression of systemt could be correlated with
the twelvefold structure of the categories, or likewise of the principles, both
of which can be regarded as representing the twelve points of the diagram in
Figure VII.5, as viewed from the perspective of a single point. In other words,
each category could be depicted as arising, in turn, out of the influence of
one of the twelve elements on the fifth element. But to elaborate the
implications of such proposals in sufficient detail would be to stray too far
from our overall goal.
The
theory put forward and defended in this chapter, especially as represented
graphically in Figure VII.5, relates to the preparatory considerations dealt
with in Parts One and Two in several ways. First, the four perspectives
examined in Chapter IV, especially as represented graphically in Figure IV.2,
delineate the basic perspectival structure of systemt. Likewise, the
special object-terms examined in Chapter VI, especially as represented
graphically in Figure VI.1, turned out to constitute a cross-section of the
whole system: we can now see that these terms relate only to stages one and
three (i.e., to what is different about an object if it is regarded on the one
hand only as intuited, or on the other hand as intuited and conceptualized, but without considering conceptual
understanding (stage two) or inferential reason (stage four) on their own).
Finally, systemt has been shown to contain a step-by-step argument which corresponds
with a surprising degree of accuracy to the architectonic structure of formal
logic, especially as represented graphically in Figure III.6. These
correlations are sufficient to establish the principle of perspective [Chapter
II] and its representation in models [I.3] as valuable tools, not only for the
interpretation of Kant's Critical philosophy, but also for philosophical thinking
in general. Nevertheless, in order to appreciate more fully the extent of their
usefulness, and thus of their applicability to the three ideas of reason [see
Part Four], we must also apply them to the other two systems which, together
with systemt, establish the Transcendental elements of Kant's System of
Perspectives.
[1] Kant's use of the term 'elements' here implies an analogy between his philosophy and the geometry developed in Euclid's Elements. (Lambert suggests this kind of an analogy in his 1766 letter to Kant [K2:10.63-4(Z1:52-3].) Moreover, just as the Elements section in Kt1 begins with an exposition on how to view Euclid's Elements in its proper perspective, so also it continues by doing the same with three other classical traditions. The Analytic of Concepts develops a doctrine of categories which enables us to view Aristotle's classic book, Categories, in its proper perspective. The Analytic of Principles develops a doctrine of principles which enables us to view Newton's classic book, Principia, in its proper perspective. And the Dialectic develops a doctrine of ideas which enables us to view the corresponding classical theory of Plato (as expressed in his Dialogues) in its proper perspective. The first Critique is an attempt to show that each of these classical theories has a proper role to play in a complete system of theoretical philosophy, but that the validity of each can be established only by limiting each to a specific perspective [see XI.2]. Without a clear recognition of Kant's Critical attitude towards his tradition (an attitude which always includes both negative and positive aspects), the significance of this modern classic cannot be fully understood.
[2] In B27:45-6 Buchdahl uses arrows in a similar way to summarize the 'movement' of steps in Kant's argument [39]. He stresses that it is 'of the utmost importance to present Kant's arguments in such summary fashion, to avoid getting lost in the usual style of endless distinctions heaped upon distinctions [54].
[3] It is important to note that, from the transcendental perspective, Kant considers something to be 'objective' if it is grounded a priori in the subject, and 'subjective' if it is grounded a posteriori in the object (i.e., in the world of appearances) [see Kt1:139-40]. Only from the empirical perspective does 'objective' refer to a grounding in outer objects and 'subjective' to inner states. Kuehn makes a similar point in K14:158, and goes a step further: 'Something that is subjective in a transcendental sense ... may very well be objective in an empirical sense (e.g., space and time). Moreover, "subjective" and "objective" have different meanings, depending on whether they are used in theoretical or practical contexts.' See also C6:154n.
[4] Kt1:91; Kt2:304; cf. E3:111 and P2:1.77-80,548. The empirical elements Kant does introduce in connection with many of his transcendental considerations must therefore be regarded as simultaneous elements into which one and the same experience could be analyzed. That is, from the empirical perspective intuitions (for example) do not necessarily come before empirical concepts; on the contrary, they could just as well arise together.
[5] As pointed out in III.4, these conditions are formal from the Perspective of transcendental logic, even though they combine to make up the content of Kant's System when viewed from the Perspective of general logic.
[6] E5:40; B6:35. Critics such as Bennett, who either reinterpret Kant's theories as 'analytic but untrivial' [B17:83], or else reject them as trivial or false, tend to be unaware that Kant himself would have regarded large portions of systemt as analytic (in method) when viewed from the empirical perspective. Since Bennett starts from the presupposition that every question must be analyzed from the empirical perspective, in terms of 'abilities' [71], it is not surprising that he finds only falsities and analytic truths in Kant's system.
[7] The word 'aesthetic' comes from the Greek 'asqhtikV', meaning 'of or for sense-perception' [L4:1.42].
[8] Kant groups this section together with the Analytic of Principles under the first division of the Transcendental Logic, which he entitles the Transcendental Analytic [see Table III.1], because both sections deal with 'the principles without which no object can be thought' [Kt1:87]. This unfortunately obscures its equally important relationship to each of the other stages. Indeed, as should become clear in VII.2-3, the first and second stages and the third and fourth stages are in some respects more closely related than the second and third. Kant acknowledges this in Kt1:169 by explaining that the Aesthetic and the Analytic of Concepts deal with 'elementary concepts' while the Analytic of Principles and the Dialectic deal with 'their employment', and that his 'division by numbered paragraphs' can therefore be discontinued at the end of the Analytic of Concepts.
[9] See II.4, VI.1 and note IV.23. Another way of making clear the sense in which sensibility assumes the transcendental perspective while judgment (as we shall see) assumes the empirical is to note that in this use the terms relate primarily to the subject's perspective on the object, whereas the broad use [see II.4 and IV.2] refers to Kant's general emphasis on the subject (in which case all four stages are transcendental). In the Aesthetic Kant refers to objects as being ideal and 'in us', while in the Analytic of Principles he refers to these same objects as being real and 'outside us' [see VI.2]. The reason for this apparent discrepancy is that the former way of looking at objects is transcendental [see e.g., Kt1:45,61-2] and the latter, empirical. Moreover, the titles of the four principles themselves clearly indicate their empirical orientation (referring, as they do, to intuition, perception, experience and empirical thought).
[10] Kt7i:476. This picture of judgment accords with Rotenstreich's account in R10:10 of 'the fundamental paradox of knowledge: by one and the same activity [viz., judgment] the distance between the subject [via understanding] and object [via sensibility] is both established and bridged.' Likewise, the distinction commonly made between 'sense', 'meaning' and 'reference' is highly suggestive of Kant's distinction between the faculties of sensibility, understanding and judgment.
[11] The important role of inference in defining the fourth stage of systemt is unfortunately obscured by the difficulty of translating 'Schluss' and related words consistently. For example, when 'Schluss' is translated as 'conclusion' [see e.g., Kt10: 114-36(120-39)], or 'Vernunftschluss' as 'syllogism' (admittedly legitimate renderings in themselves), the reader is left unaware (aside from occasional notes by translators) of the fact that both terms literally refer to the function of inference. As a result, the parallel relationship between inference and its counterparts in the previous stages (viz., judgment, conception and intuition) can easily go unnoticed [e.g., Kt1:378]. For the sake of clarity, therefore, I shall henceforth alter the translation of Kant's use of such terms whenever appropriate.
[12] Kant does this, though not in an entirely clear way, in K2:10.471-2(Z1:125) and K2:11.300-1(Z1:182). A model of this 2LAR has already been given in Figure III.10; but the following discussion specifies the derivation of this division more precisely than in III.4.
[13] Kant's doctrine of the transcendental object was thoroughly examined in VI.2. The reasons for placing the transcendental object here in the first stage rather than in the second stage are discussed in Appendix VII.B.
[14] See Kt1:347. As Allison rightly says, 'unconceptualized representations' are for Kant the 'materials for knowledge' [A11:25; cf. K2:17.616-7]. Thus sensibility, the home of such representations, is the material (--) stage in systemt [see note VII.23].
[15] E5:18,37. Walsh notes that intuition 'can be described as awareness of particulars only proleptically, since strictly it is not a species of acquaintance' [W9:15]. That is, an intuition provides such an awareness only when it comes under some concept. Thus, although Kant sometimes refers to space and time as 'concepts', his official view is that spatial and temporal relations 'lie entirely outside the concepts of understanding, strictly regarded' [Kt1:159]. For an excellent discussion of Kant's theory of intuition, see A7:68-72,75-92. The important point to remember is that intuitions always convey singular representations immediately, whereas concepts convey common representations mediately [see e.g., Kt1:136n,298, 377; Kt10:91(96); Kt69:325].
[16] Kt1:323; s.a. 208 and Kt19:399; Kt69:266; cf. P2:1.112. Kant also regards certain mathematical (especially geometrical) judgments as dependent on pure intuition [Kt1:16-7,A24,40-1,64-6,749-50]. Some problems concerning this assumption are discussed in Appendix VII.C.
[17] Kant explains: '"I", as thinking, am an object of inner sense, and am called "soul". That which is an object of the outer senses is called "body"' [Kt1:400; s.a. 50,69]. Soul and body, then, are not two essentially separate realities, but two manifestations of one and the same human sensibility. (In Kt69:270 Kant makes a similar point about the 'twofold self, the I as subject and the I as object', which arises in the second stage; he stresses that this self is a unity, not 'a double personality'.) When the perspectival character of Kant's theory is recognized, we can see that such statements do not support the traditional assumption that, as Walsh puts it [W9:192], Kant 'worked generally within Cartesian assumptions about the relations of mind and body.' On the contrary, Kant explicitly criticizes Descartes' assumptions in Kt1:A341-405.
[18] Kt1:182; s.a. Kt6:214 and Kt19:396-405. Some ambiguities relating to Kant's use of the term 'inner sense' are discussed in Appendix VII.D.
[19] Kt1:59. This, of course, applies only from the transcendental perspective (stage one), in which case it implies that 'thinking in spatial [and temporal] terms ... is a purely human way of thinking, determined by the nature of human experience' [M6:136]. Kant points out that 'other thinking beings' might be able to intuit space (and time) in a way different from the way humans do [Kt1:43]. To deny the subjective necessity of the inner forms of representation would be, for Kant, tantamount to claiming we can attain a wholly perspectiveless knowledge which somehow exists outside the boundaries of time and space (and the categories). (Yet this would require a perspective from which we could view the whole space-time continuum at a single glance.) From the empirical perspective (stage three), outer appearances are distinct from us in the sense that they are objects which are outside of our inner sense [cf. VI.2 and B20:51]. Similarly, although the intuitions of time and space logically precede the appearance transcendentally, they are chronologically simultaneous with it empirically.
[20] Kt1:52. Thus, Kant's doctrine of pure spatio-temporal intuition, which regards space and time as 'the relations in which our sensa are given' [P2:1.103], revises the then popular notion of 'absolute space', so that pure space is now 'nothing at all belonging to the existence of things', but 'merely to the determination of concepts' [Kt3:563].
[21] Kt1:74; s.a. Kt19:96. It is impossible to imagine how something could appear without being sensed, because we experience appearances and sensations simultaneously. (The alternative would be to say 'sensations are elements of appearances' [as in G7:513]; yet this is absurd, since it would require a sensation of something which has not yet appeared!) When we recall that these distinctions are logical and not necessarily chronological [see VII.1], we can nevertheless regard the third (synthetic) function in stage one as that of representing appearances as sensations.
[22] Another reason may be that he regards the investigation of actual sensations as an empirical task. His transcendental task in this first stage, by contrast, is to discover the formal conditions which must pertain in order for any sensations to arise.
[23] Kt1:74; cf. 270,286,323. Kotzin wrongly takes Kant's classification of sensation as the 'material' element in knowledge to refer to its place within the first stage, rather than to the role of the first stage itself in systemt as a whole [see note VII.14]. She says 'sensation is the determinable, material factor in empirical intuition', which 'remains in our account when we are considering the sensible, intuitive side of empirical cognition and when Space and Time, as formal factors, are not taken into account' [K10:114-5e.a.]. But she fails to explain on the one hand how sensations would be possible outside the context of space and time, and on the other how her understanding of sensation differs from what the present interpretation regards as the material element in the first stage (viz., the transcendental object).
[24] Kt1:155. Wolff points out that 'the assertion that a synthetic unity of representations cannot be given, but must be produced by the mind ... is so basic to Kant's philosophy that he never attempts to prove it', except by elaborating its implications for systemt [W21:69n]. This assumption is indeed an integral part of Kant's Copernican revolution.
[25] Heidegger believes the imagination's role as mediator between sensibility and understanding makes it the 'common root' mysteriously uniting these two faculties [H11:144-8; cf. Kt1:29]. This is supported by Kant's view of the imagination as an 'original' faculty [A94], intimately connected with both sensibility and understanding [see W21:77 and Ap. VII.D-E], yet also, as we shall see in VII.3.A, playing an important role in stage three.
[26] Kt1:A121. In A113 Kant explains: 'The ground of the possibility of the association of the manifold, so far as it lies in the object, is named the affinity of the manifold.' It is this affinity, and not (as Walsh suggests [W9:116]) the synthesis which brings it to light, which can be described as 'connectibility'. Moreover, affinity is directly dependent on apperception (step six) [Kt1:A122], and is therefore the basis of the 'objective deduction' [see Ap. VII.G].
[27] Kant does seem to suggest at certain points that apperception follows synthesis immediately [see e.g., Kt1:A94,A124]. Moreover, his overall exposition in both editions of the Deduction is misleading, because he discusses apperception and synthesis before discussing the role of the categories [cf. A98-111,129-42 and A111-30,143-69]. But this analytic procedure is to be expected from a deduction: in order to deduce the necessity of the categories, Kant argues for the necessity of the material step (synthesis of imagination) and of the synthetic step (pure apperception), then shows how the categories are required as the formal step which leads from the former to the latter [see e.g., A119]. Allison attests to the 'analytical' character of much of Kant's argument in the Deduction [A12:9], and emphasizes the same three steps we have chosen as the key to stage two: 'the transcendental synthesis of the imagination and its relationship to apperception and the categories constitutes the real nerve of the Deduction' [10]. The close relationship between the categories and apperception leads Wolff to proclaim that 'the categories ... are the unity of apperception' [W21:178]. But, as we shall see, such an identification is not strictly accurate.
[28] Because of its affinity with 'intuition', I have been using 'conception' as a technical term referring to the power of forming concepts, even though this word appears only nine times in Kt1 [see Pq10:67], and never in connection with 'intuition' [but see K2:11.302(Z1:184)]. In this sense 'categorial conception' refers to the operation of the categories, which, as Kant says, 'contain ... the logical function for bringing the manifold under a concept' [Kt1:A245]. Other, less comprehensive terms could just as well have been used to name this power, such as 'thinking' (which produces thought), 'conceptualizing' (which produces concepts) or 'categorization' (which uses categories to make concepts).
My interpretation of categorial conception contradicts Paton's claim in P2:2.82 that 'the lack of homogeneity between appearance and category indicates that the [direct] subsumption ... of appearances under the categories is impossible.' I would argue that this is precisely what Kant has in mind when he refers to the activity of 'thinking'. He brings up this 'lack of homogeneity' in the third stage of his argument [see VII.3.A] in order to show it is impossible to produce empirical knowledge by means of such direct subsumption alone.
The word 'concept' in contexts such as this can denote either an empirical or a pure concept. Allison defines 'a concept (analytic universal)' in A11:35 as 'a set of marks (themselves concepts), which are thought together in an "analytic unity," and which can serve as a ground for the recognition of objects. These marks collectively constitute the intension of a concept.' Because Kant largely ignores the role of empirical concepts, most commentators follow suit [e.g., E5: 133]. Schrader does mention that they 'are not derivable from the categories but must conform to them' [S6:142-3]. And Pippin devotes a great deal of attention to the subject [P8:103-23,143-50]; but the maze of problems he raises is of little help in determining how Kant understood such issues.
[29] E.g., Kt1:305. Although the pure intuitions of space and time are sometimes called 'concepts' [e.g., 37,46; cf. A7:72], and although the term also has empirical [Kt1:A111,A125] and other applications [367,377,434], Kant uses it most often in its strict logical sense to designate an object 'not of intuition and sensibility but of pure a priori thought ..., apart from all conditions of sensibility' [120].
[30] Kt1:A106. Wolff regards this definition as the essential tenet of the entire Analytic [W21:viii], and devotes much of his commentary to expounding its implications [s.e. 121-31]. At one point he lists the 'three characteristics of rule-governed activities' as: (1) they 'can legitimately be said to proceed correctly or incorrectly'; (2) 'the order of the steps of the activity is not haphazard'; and (3) they are characterized by their 'coherence' [122-3]. Whereas empirical concepts are 'first-order' rules, pure concepts are 'second-order' rules [124-5]. Raschke distinguishes between rules and laws by saying the former provide general guidelines which are not universal or necessary, while the latter are obligatory [R3:18-24].
[31] These categories 'are nothing but the condition of thought in a possible experience, just as space and time are the conditions of intuition for that same experience' [Kt1:A111]. They comprise 'all original pure concepts of synthesis that the understanding contains within itself a priori' [106], and through which 'appearances have a necessary relation to the understanding' [A119]. Paton describes them as 'the ultimate predicates which universally and necessarily apply to every thing so far as it is a thing' [P2:1.257]. But the categories are not just highly general and all-encompassing empirical concepts: when functioning as the formal condition for all conception, they cannot themselves be empirical. Hence Kant describes their status further as 'concepts which prescribe laws a priori to appearances, and therefore to nature, the sum of all appearances ... [These] laws do not exist in the appearance but only relatively to [the subject], so far as it has understanding.... [They] instruct us in regard to experience in general, and as to what it is that can be known as an object of experience' [Kt1:163-5]. Like space and time, these natural laws must therefore 'lie in ourselves', for 'the understanding does not draw its laws (a priori) from nature, but prescribes them to nature' [Kt2:320].
[32] The details of Kant's choice of categories will be examined in more detail in VII.3.A, where we will discuss their application to appearances in the form of principles [see also III.3]. Some of the many specific problems and ambiguities raised by Kant's discussion of the categories are discussed in Appendix VII.F.
[33] Kant refers to this 'transcendental consciousness' [Kt1:A117n] as the 'abiding and unchanging' faculty of 'pure apperception' [A123] in order to distinguish it from 'empirical apperception'. The latter refers to one's actual awareness of the 'always changing' manifold of one's own perceptions [A107]. Although Kant sometimes seems to equate it with inner sense [e.g., A107], they should technically be distinguished [cf. P2:1.399-400]. Inner sense as such denotes the unorganized manifold of transcendental appearances which present themselves to a person's inner intuition [but cf. Ap. VII.D]; empirical apperception refers to one's consciousness of these perceptions as they are synthesized in thought. Hence, they denote the same object, but viewed either from the transcendental or the empirical perspectives of systemt.
[34] Although the function of the fourth step in relation to the third is the synthesis of imagination, it nevertheless plays a material role in the second stage. For the purpose of synthesizing the sensations presented by the third step is to bring them to a level of determination (viz., as perceptions) which can be used by the understanding as the matter for its conceptual synthesis. Recognizing the material status of the fourth condition can help us to understand why 'Combination [or synthesis] serves the same function [in the arguments of the Deduction in B] as the transcendental object [the material step in the first stage] did in A' [G11:200]. And this, in turn, helps us explain why the second edition is an improvement on the first, since the transcendental object belongs primarily to stage one.
[35] Allison equates 'possible experience' and 'possible knowledge' in A12:5. But the two should be kept distinct, as referring to the goals of the first and second stages, respectively.
[36] Kt1:75; s.a. 314 and P2:2.21n,27n. The word 'understanding' in this context must be interpreted narrowly, since Kant also portrays the understanding (in its broadest sense [see VII.1]), as involved with pure intuitions as well.
[37] This, no doubt, is why Kant stresses in Kt1:244 that 'Understanding is required for all experience and for its possibility', even though he elsewhere talks loosely as if sensibility on its own can be called 'possible experience' [199]. Evidently, sensibility can only properly be referred to in this way when its necessary connection with the understanding is taken into account. The same holds, of course, for understanding as 'possible knowledge' in its connection with sensibility. Both phrases look forward to the development of empirical knowledge, which includes 'all synthetic unity of perceptions' [226; cf. K3:52].
[38] This application of synthesis should be distinguished from the synthesis of imagination in step four, from the synthesis in synthetic (as opposed to analytic) judgments, and from the synthetic method in general [see III.3 and IV.2]. The lucidity of interpretations such as Wolff's, which emphasize the role of synthesis, could be substantially increased by recognizing the differences between these types of synthesis [cf. W21:180,201 and H4:xxii-cxv].
[39] Kt1:93-4. Pippin suggests that this association between concepts and judgments is the 'clue' Kant intends the Metaphysical Deduction to provide [P8:94,97]. Although I believe the nature of Kant's clue goes beyond this [cf. note III.17], Pippin's view does point up Kant's misplacement of this section, inasmuch as the transition it hints at is not between the first and second stages, but between the second and third.
[40] Kt1:178; cf. P2:2.40. Kant's reasons for singling out time are relatively clear. In the second stage both space and time were abstracted from the appearance. But the goal towards which the third stage works is the empirical knowledge of outer objects; so Kant re-introduces time as its first component in order to establish the inner framework into which all objectively real objects must fit.
[41] Kt1:179-80e.a. Kant says the schema of a sensible concept may be accompanied by an image; but 'the schema of a pure concept of understanding can never be brought into any image whatsoever' [181]. As an example of the latter he says the schema of 'the concept of a triangle in general' is beyond any particular sensible image: 'The schema of the triangle can exist nowhere but in thought' [180]. Thus Allison explains that, 'unlike the image, the schema is not something extraneous to the concept, but is really the concept itself qua realized in intuition' [A7:89; cf. P8:140]. Heidegger draws a helpful distinction along these lines between an 'image' and a 'schema-image' [H11:97-108], and explains that the unifying procedure of the latter 'is never apprehended in itself', but only 'in the exercise of its regulative function' [101].
[42] Cf. Kt1:195-7,355-9, and note VII.30; s.a. P2:1.495. In Kt1:187-8 Kant says 'the pure understanding ... is itself the source of principles', and the natural laws, or rules of experience, 'stand under higher principles of understanding.' In Kt1:359 he gives a slightly different account of their relationship: 'Understanding ... secures the unity of appearances by means of rules, and reason ... secures the unity of the rules of understanding under principles.' (As we shall see, this reflects the parallel between the third and fourth stages.) Bennett expresses the role of principles more simply [B17:61]: they define 'what our intuitions must be like in order to be intellectually manageable.' In so doing, 'principles ... proceed from concepts to intuition, not from intuition to concepts' [Kt1:199].
[43] P2:1.220. 'The principle of [non]contradiction', Kant says, 'must therefore be recognised as being the universal and completely sufficient principle of all analytic knowledge; but beyond the sphere of analytic knowledge it has, as a sufficient criterion of truth, no authority and no field of application' [Kt1:191].
[44] Kt1:223. Because the categories as applied in the principles are always schematized (i.e., restricted by the schema), the principles can be called 'schematized categories' [P2:2.19n,182], though Kant himself never uses this phrase. Ewing gives a good summary of the relationship between pure categories, schemata and schematized categories in E5:134-5.
[45] Kt1:200. Although Kant sometimes speaks loosely as if the principles themselves were axioms, anticipations, etc. [cf. 760-1 and P2:2.124n], they are strictly speaking the ultimate principles which make possible these specific types of principles [cf. note VII.46].
[46] Kt1:200-1. Kant explains: 'It is through these principles of pure understanding that the special principles of mathematics and dynamics become possible. I have named them ... on account rather of their application than of their content' [202]. Thus, they are not themselves principles of mathematics and dynamics, but are the bases of these sciences.
[47] Kt1:207. Whereas axioms determine that objects will have characteristics directly related to their appearance in time and space, anticipations determine 'that an object is more than the space which it occupies and the time through which it lasts' [P2:2.139].
[48] Kt1:291. Kant is perhaps not clear enough in his explanation of the role of space in the chapter on the principles. Nevertheless, it is this reintroduction of space which makes the chapter a suitable place for him to insert his second-edition revision of the Refutation of Idealism [274-9], where the necessity of outer objects in space is firmly established (from the empirical perspective). The role of the principles in determining how it is that empirical objects (viewed from the empirical perspective) stand out from the subject as independent realities in the outer world of space and time could be referred to, albeit rather fancifully, as 'extuition'. Along these lines, we could add, in a Heideggerian vein, that it is only because the principles enable a representation to be e-jected from the subject that it can become an ob-ject (i.e., can stand opposite the subject) [cf. H11:35-6].
[49] Kt1:241. This Copernican assumption [cf. III.1] helps explain why Kant's special type of 'transcendental argument' [see V.3, Ap. V and note IV.26] can insure that the principles 'are not only true a priori, but are indeed the source of all truth (that is, of the agreement of our knowledge with objects)' [296]. Kant's assumption here is not that we all decide to prescribe certain a priori principles to our experience, but that human knowledge necessarily presupposes such principles, regardless of a person's conscious recognition of them.
[50] Kt1:142; s.a. P2:1.571; cf. Kt7:20. Bird notes that something objectively real 'can be conceived independently of any particular experience, but not independently of every experience' [B20:145].
[51] Kt1:195; cf. P2:2.88-9,93-6. As Kant says in Kt1:303: 'the Transcendental Analytic leads to this important conclusion, that the most the understanding can achieve a priori is to anticipate the form of a possible experience in general.'
[52] Kt1:353-4,397. Rotenstreich disagrees with Kant's emphasis on reason's natural tendency towards illusion, and regards it as a result of the historical influence of rationalism on Kant [R11:66-7]. 'That there is no necessity' in committing such errors, he explains, 'is clearly shown by Kant himself in his attempt to replace traditional systems of metaphysics by regulative concepts' [70]. Although this is a good point, I would suggest in Kant's defense that by calling these illusions 'natural' he may not mean that reason unavoidably succumbs to them, but only that the source of errors is such that they will always, as it were, tempt reason to fall for them when it asks questions about ultimate reality. Such temptation is unavoidable because of the opposition between sensibility (--) and reason (++), as the first and last stages of systemt: if we are not careful in using our reason, we will naturally tend to forget the sensible ground upon which alone it is able to stand.
[53] Kt1:379. Kant's notion of 'the maximum' [693] is roughly equivalent to that of the unconditioned. Thus he says 'the idea of [the maximum of] reason is an analogon of a schema of sensibility; but with this difference, that the application of the concepts of understanding to the schema of reason does not yield knowledge ..., but only a principle for the systematic unity of the entire conceptual perspective' [693e.a.]-i.e., only an 'idea' (in its technical sense, described below). The implications of this limitation of knowledge will be examined shortly.
[54] Kt1:364; cf. 358. This does not contradict my proposal in IV.3 that hypothetical reflection yields analytic a posteriori knowledge (or belief); for Kant is here describing the role of the tenth step in his overall system of conditions (all of which proceed synthetically), and so is best understood as referring to the synthetic method which must be employed to advance from step nine to step eleven. As applied to inferences in general, Kant refers to the synthetic method as 'a parte priori' (ascending from conditioned to unconditioned) and the analytic method as 'a parte posteriori' (descending from unconditioned to conditioned) [389].
[55] Kt1:511. This characteristic of the unconditioned object is also true of the transcendental object, the synthesis of imagination, and the schematism of understanding, all of which arise in the first step of their respective stages in systemt.
[56] Kt1:672; s.a. 368,595-6,670. 'An idea is nothing else than the concept of a perfection which has not yet been met with in experience'; but it is not 'for that reason impossible' [Kt39:444(109)].
[57] Kt1:366, alt. Kemp Smith, incidentally, paraphrases the latter quote as '[can] be obtained ... only by inference', which could be taken wrongly to imply that inference is itself the only element in the fourth stage.
[58] Dister points out a similarity between the schema's influence on the understanding and the idea's influence on reason [D4:262-3]. But a more direct parallelism exists between the influence of the categories (+-+) on the manifold of appearances (--+) and that of the ideas (+++) on the phenomenon (-++), both being the influence of a stage's formal step on the formal step in the preceding stage (as symbolized by the change from + to - in the first term of each of the corresponding logical components). Kant alludes to this parallelism in Kt1:368: 'just as we have entitled the pure concepts of understanding categories, so we shall give a new name to the concepts of pure reason, calling them transcendental ideas.' In order to make this parallelism clear the summary of step eleven regards ideas as both functions and products: just as conception uses the categories to form concepts, inference uses the ideas (or we might say 'ideation') to form ideas.
[59] Kt1:391-2. Kant says the 'transcendental ideas ... follow the guiding thread of the categories' [392]; however, they are actually arranged in three groups of four (rather than four groups of three) because they are based on the synthetic relation between the three analogies, each of which is expounded in terms of a 2LAR [397]. The only exception to the fourfold structure of the analysis of each is Kant's treatment of the Ideal of Pure Reason [595-670], which I shall discuss briefly in X.2 and in more detail in Pq20.
[60] Kt1:726. The phrase emphasized by Kant indicates he is thinking here of the hypothetical perspective, which looks towards the world, as opposed to the speculative perspective, which looks beyond the world.
[61] Rotenstreich is correct in stating: 'Dialectic in Kant mainly means the reification of ideas, the trend of reason towards hypostatic assumptions' [R11:63]. However, he unfortunately fails to distinguish sufficiently between this and the hypothetical 'acting as if' which Kant puts in its place. Only from the latter perspective are objects properly regarded as 'the ever-unattainable goal of investigation' [W5:182]. As I hope to demonstrate in Pq21 [s.a. XI.4], Kant's hypothetical perspective is much more relevant to modern conceptions of science and scientific inquiry than most interpreters recognize.
[62] Kant sometimes hints at something like this sort of diagram (at least as an 'archetype' [see I.3]), as when he refers to 'ascending' from the conditioned (step nine) to the unconditioned (step ten) by the synthetic method [e.g., Kt1:394]. Likewise, he says in Kt7:410 that to move 'downwards' from God to nature 'is a priori', while to 'move from below upwards' is 'a posteriori'-a metaphor which is consistent with my placement of the two a priori perspectives on the downward arc, and the two a posteriori perspectives on the upward arc.
[63] Schrader seems to be hinting as some such associations when he says in S6:139 that 'the categories of quantity and quality are constitutive of the space-time manifold as such [just as intuitions and concepts are constitutive of judgments], while the relational categories are constitutive of objects in space and time [i.e., phenomena].'
