FIRST DIVISION
TRANSCENDENTAL ANALYTIC
TRANSCENDENTAL analytic consists in the dissection of all
our a priori knowledge into the elements that pure understanding
by itself yields. In so doing, the following are the
points of chief concern: (1) that the concepts be pure and
not empirical; (2) that they belong, not to intuition and
sensibility, but to thought and understanding; (3) that
they be fundamental and be carefully distinguished from
those which are derivative or composite; (4) that our table
of concepts be complete, covering the whole field of the pure
understanding. When a science is an aggregate brought into
existence in a merely experimental manner, such completeness
can never be guaranteed by any kind of mere estimate. It is
possible only by means of an idea of the totality of the priori
knowledge a yielded by the understanding; such an idea can
furnish an exact classification of the concepts which compose
that totality, exhibiting their interconnection in a system. A65
Pure understanding distinguishes itself not merely from all
that is empirical but completely also from all sensibility. It
is a unity self-subsistent, self-sufficient, and not to be increased B90
by any additions from without. The sum of its knowledge thus
constitutes a system, comprehended and determined by one
idea. The completeness and articulation of this system can at
the same time yield a criterion of the correctness and genuineness
of all its components. This part of transcendental logic
requires, however, for its complete exposition, two books, the
one containing the concepts, the other the principles of pure
understanding.
