 The nature of beauty is one of the most enduring and controversial themes in Western philosophy, and is—with the nature of art—one of the two fundamental issues in the history of philosophical aesthetics. Beauty has traditionally been counted among the ultimate values, with goodness, truth, and justice. It is a primary theme among ancient Greek, Hellenistic, and medieval philosophers, and was central to eighteenth and nineteenth-century thought, as represented in treatments by such thinkers as Shaftesbury, Hutcheson, Hume, Burke, Kant, Schiller, Hegel, Schopenhauer, Hanslick, and Santayana. By the beginning of the twentieth century, beauty was in decline as a subject of philosophical inquiry, and also as a primary goal of the arts. However, there was revived interest in beauty and critique of the concept by the 1980s, particularly within feminist philosophy.
