This is the best book in the philosophy of art in the last half century, at least. It presents a systematic, seriously-argued, soberly detailed account of the arts in terms of symbol (referring) systems, especially as they do or do not involve notational systems -music and dance, say, as opposed to painting and drawing. The book deploys many of Goodman's justly famous ideas from his previous work in the philosophy of language, of science, and epistemology. It is elegantly written and will, in the middle chapters, require sober work at following the more formal points on notation. But it is all worth it. Disregard the first review above, where its author misses the arguments against the resemblance view of depiction. This book is usefully read along with Reconceptions in Philosophy by Goodman and Elgin.
