Introduced into the philosophical lexicon during the Eighteenth Century, the term "aesthetic" has come to be used to designate, among other things, a kind of object, a kind of judgment, a kind of attitude, a kind of experience, and a kind of value. For the most part, aesthetic theories have divided over questions particular to one or another of these designations: whether artworks are necessarily aesthetic objects; how to square the allegedly perceptual basis of aesthetic judgments with the fact that we give reasons in support of them; how best to capture the elusive contrast between an aesthetic attitude and a practical one; whether to define aesthetic experience according to its phenomenological or representational content; how best to understand the relation between aesthetic value and aesthetic experience.
