The last few decades have witnessed an explosion in ideas and theories on art. Art itself has never been so topical, but much recent thinking remains inaccessible and difficult to use. This book assesses the work of those thinkers (including artists) who have had a major impact on making, criticizing and interpreting art since the 1960s. With entries by leading international experts, this book presents a concise, critical appraisal of thinkers and their ideas about art and its place in the wider cultural context. A guide to the key thinkers who shape today's world of art, this book is a vital reference for anyone interested in modern and contemporary art, its history, philosophy and practice.
