Were Kant really arguing here and in the second argument on space solely
from the _objective_ necessity of time and space, this criticism would
be unanswerable. But even taking the argument in its first edition form,
as an argument from the _psychological_ necessity of time, it lies open
to the same objection as the argument on space. It rests upon a false
statement of fact. We cannot retain time in the absence of all
appearances of outer and inner sense. With the removal of the given
manifold, time itself must vanish.
=Fourth Argument.=[494]--This argument differs only slightly, and mainly
through omissions,[495] from the fourth[496] of the arguments in regard
to space; but a few minor points call for notice. (_a_) In the first
sentence, instead of intuition, which alone is under consideration in
its contrast to conception, Kant employs the phrase “pure form of
intuition.” (_b_) In the third sentence Kant uses the quite untenable
phrase “given through a single object (_Gegenstand_).” Time is not
given from without, nor is it due to an object. (_c_) The concluding
sentences properly belong to the transcendental exposition. They are
here introduced, not in the ambiguous manner of the fourth[1] argument
on space, but explicitly as a further argument in proof of the intuitive
character of time. The synthetic proposition which Kant cites is taken
neither from the science of motion nor from arithmetic. It expresses the
nature of time itself, and for that reason is immediately contained in
the intuition of time.
=Fifth Argument.=--This argument differs fundamentally from the
corresponding argument on space, whether of the first or of the second
edition, and must therefore be independently analysed. The thesis is
again that time is an intuition. Proof is derived from the fact that
time is a representation in which the parts arise only through
limitation, and in which, therefore, the whole must precede the parts.
The original (_ursprüngliche_) time-representation, _i.e._ the
fundamental representation through limitation of which the parts arise
as secondary products, must be an intuition.
