Kant’s view of analytic thinking is entirely dominated by the
substance-attribute teaching of the traditional logic. A concept must,
in its connotation, be an abstracted attribute, and in its denotation
represent a class. Relational thinking, and the concepts of relation,
are ignored. Thus, in the _Aesthetic_, as we have already noted,[681]
Kant maintains that since space and time are not generic class concepts
they must be intuitions. This argument, honestly employed by Kant, shows
how completely unconscious he was of the revolutionary consequences of
his new standpoint. Even in the very act of insisting upon the
relational character of the categories, he still continues to speak of
the concept as if it must necessarily conform to the generic type. In
this, as in so many other respects, transcendental logic is not, as he
would profess, supplementary to general logic; it is its tacit
recantation. Modern logic, as developed by Lotze, Sigwart, Bradley, and
Bosanquet, is, in large part, the recasting of general logic in terms of
the results reached by Kant’s transcendental enquiries. Meantime,
sufficient has been said to indicate the strangely limited character of
Kant’s doctrine of the logical concept.
But on one fundamental point Kant breaks entirely free from the
traditional logic. The following passage occurs in the above-quoted
pamphlet on _The Mistaken Subtlety of the Four Syllogistic Figures_:
“It is clear that in the ordinary treatment of logic there is a
serious error in that distinct and complete concepts are treated
before judgments and ratiocinations, although the former are only
possible by means of the latter.” “I say, then, first, that a
_distinct_ concept is possible only by means of a _judgment_, a
_complete_ concept only by means of a _ratiocination_. In fact, in
order that a concept should be distinct, I must clearly recognise
something as an attribute of a thing, and this is a judgment. In
order to have a distinct concept of body, I clearly represent to
myself impenetrability as an attribute of it. Now this
representation is nothing but the thought, ‘a body is
impenetrable.’ Here it is to be observed that this judgment is not
the distinct concept itself, but is the act by which it is
realised; for the idea of the thing which arises after this act is
distinct. It is easy to show that a complete concept is only
possible by means of a ratiocination: for this it is sufficient to
refer to the first section of this essay. We might say, therefore,
that a distinct concept is one which is made clear by a judgment,
and a complete concept one which is made distinct by a
ratiocination. If the completeness is of the first degree, the
ratiocination is simple; if of the second or third degree, it is
only possible by means of a chain of reasoning which the
understanding abridges in the manner of a sorites.... Secondly, as
