This chapter argues that, on Kant’s account, aesthetic pleasure is an exercise of rational agency insofar as, when proper, (1) it involves consciousness of its ground (the reasons for having it) and thus of itself as properly responsive to its object, and (2) actually feeling this pleasure involves its endorsement as an attitude to have. I claim that seeing this clearly requires that we divest ourselves of the following dilemma: either pleasures are the noncognitive, passive ways through which we are affected by objects or they are cognitive states by virtue of the theoretical beliefs or practical desires they involve. On my reading of Kant, this dilemma is false. Aesthetic pleasure is neither passive, nor theoretically or practically cognitive, and yet, it is an exercise of rational agency by virtue of belonging to a domain of rationality that is largely overlooked in the history of philosophy: aesthetic rationality.
