Book excerpt: Aesthetics is not a "factual" discipline; there are no aesthetic facts. The word itself is derived from the Greek word for "feeling" and the discipline arises because of the need to find a place for the passions within epistemology--the branch of philosophy that investigates our beliefs. Aesthetics is more than just the study of beauty; it is a study of that which appeals to our senses, most often in connection with the classification, analysis, appreciation, and understanding of art. The A to Z of Aesthetics covers its history from Classical Greece to the present, including entries on non-western aesthetics. The book contains a chronology, an introductory essay, a bibliography, and hundreds of cross-referenced dictionary entries on the main concepts, terminology, important persons (philosophers, critics, and artists), and the rules and criteria we apply in making judgments on art. By providing concise information on aesthetics, this dictionary is not only accessible to students, but it provides details and facts to specialists in the field.
