Disinterested Pleasure and the Universality of Taste

The concept of "disinterestedness" (Interesselosigkeit) is Kant's answer to the question of how an aesthetic judgment, which is grounded in nothing but a subject's own felt pleasure, can nonetheless differ fundamentally from a mere private preference such as liking a particular wine. Kant defines "interest" as "the satisfaction that we combine with the representation of the existence of an object," and argues that in a pure judgment of taste we are indifferent to whether the object actually exists; what matters is solely the way its form is represented to us in contemplation. This is why Kant insists a judgment of taste is not, strictly, a cognitive judgment about the object's properties at all, but rather refers the representation, via the feeling of pleasure or displeasure, to the subject and its state — the judgment "this rose is beautiful" reports something about the harmonious activity of the judging subject's own faculties occasioned by the rose, not a predicate straightforwardly true of the rose as an object of empirical knowledge like its colour or weight.
