 Kant claims in the Introductions to the Critique of Judgment that it is an a priori principle of reflecting judgment that nature is “purposive for our cognitive faculties” or “purposive for judgment”. This principle is, in the terminology of the Critique of Pure Reason, regulative rather than constitutive. We cannot assert that nature is, as a matter of objective fact, purposive for our cognitive faculties, but it is a condition of the exercise of reflecting judgment that we assume nature’s purposiveness for our cognitive faculties. The assumption that nature is purposive for our cognitive faculties is not, strictly speaking, part of teleology, since the purposiveness at issue is subjective, and teleological judgments are concerned only with objective purposiveness (see, e.g., FI VII, 20:221). But it is nonetheless relevant to Kant’s teleology, since our entitlement to ascribe objective purposiveness to natural things, in particular to organisms, derives from our more fundamental entitlement to regard nature as (subjectively) purposive for our cognitive faculties (FI VI, 20:218; Introduction VIII, 5:193–194).
