By the analytic of concepts I do not mean the analysis of concepts, nor the ordinary procedure in philosophical investigation, of analyzing and clarifying (as regards their content) concepts that present themselves, but the as yet little attempted analysis of the faculty of understanding itself, so as to investigate the possibility of a priori concepts by seeking that possibility in the understanding alone (as the birthplace of those concepts), and by analyzing the pure use of those concepts (in general); for this is the proper business of transcendental philosophy; the rest is the logical treatment of concepts in philosophy in general. We will therefore pursue the pure concepts as far as their first seeds and predispositions in the human understanding, in which they lie ready until those concepts are, on the occasion of experience, finally developed, and are, by the very same understanding, exhibited in their purity, free of the empirical conditions attaching to them.
