A Category is primarily a class of Judgments. Since arguments are
composed of judgments, a category is also a class of arguments; that
is to say, the argument follows the classification of the judgment.
This is not the practice of syllogists, who have categories for
judgments only, the arguments being classified according to verbal
expression.
I distinguish six categories--two Natural and four Artificial. The
judgments of a natural category concern experience presented in
a synthesis whose composition is due to the noumenal mind; the
categories corresponding to this definition are--
Inherence--
Association.
An artificial category is so called because the synthesis is formed by
the subjective mind.
