Now although this idea of the sum total of all possibility, insofar as it grounds every thing as the condition of its thoroughgoing determi nation in regard to the predicates which may constitute the thing, is it self still indeterminate, and through it we think nothing beyond a sum total of all possible predicates in general, we nevertheless find on closer investigation that this idea, as an original concept, excludes a multiplic ity of predicates, which, as derived through others, are already given, Or cannot coexist with one another; and that it refines itself to a concept thoroughly determined a priori, and thereby becomes the concept of an individual object that is thoroughly determined merely through the idea, and then must be called an ideal of pure reason.
