Human reason consists of all the patterns of individuation and order, of a priori concepts, principles, ideas and the ideal, as well as interests, needs, imperatives, postulates, and ends, whether embodied in theory, in practice, or in aesthetic judgment. Our reason is not an aggregate but a system. In other words, the unity of all these aspects, parts, and activities of reason is determined a priori and, therefore, necessarily. This multiplicity is subordinated to the unity of the end of reason (...) as a whole. Kant deals with this problem in “The Architectonic of Pure Reason” of the Critique of Pure Reason. Architectonic is the art of systems, a theory about the scientific nature of our knowledge, since there is no science without systematic unity. (shrink)
