 The idea that the assumption of nature’s purposiveness for our cognitive faculties is a condition of empirical concept-formation is potentially helpful in addressing the problem of the unity of the Critique of Judgment (see  Section 1),  given that the free play of imagination and understanding characteristic of judgments of beauty is often seen as closely related to the activity of imagination which allows us to categorize objects as having general features and falling into kinds. More generally, the question of how to relate the principle of nature’s purposiveness for our cognitive faculties to the activity of the cognitive faculties in aesthetic judgment has been discussed by a number of commentators; see, for example, Ginsborg (1990b), Pippin (1996), Allison (2001: ch. 2), Guyer (2003b), Baz (2005), Caranti (2005), Hughes (2006; 2007: ch. 7), Gentry (2018) and Geiger (2020).
