 Kant’s account of aesthetics and teleology is ostensibly part of a broader discussion of the faculty or power of judgment [Urteilskraft], which is the faculty “for thinking the particular under the universal” (Introduction IV, 5:179). Although the Critique of Pure Reason includes some discussion of the faculty of judgment, defined as “the capacity to subsume under rules, that is, to distinguish whether something falls under a given rule” (A132/B171), it is not until the Critique of Judgment that he treats judgment as a full-fledged faculty in its own right, with its own a priori principle, and, accordingly, requiring a “critique” to determine its scope and limits.
