Aesthetics (/ɛsˈθɛtɪks, iːs-/) is a branch of philosophy that explores the nature of art, beauty, and taste, with the creation and appreciation of beauty.[1]

In its more technical epistemological perspective, it is defined as the study of subjective and sensori-emotional values, sometimes called judgments of sentiment and taste.[2] Aesthetics studies how artists imagine, create and perform works of art; how people use, enjoy, and criticize art; and what happens in their minds when they look at paintings, listen to music, or read poetry, and understand what they see and hear. It also studies how they feel about art—why they like some works and not others, and how art can affect their moods, beliefs, and attitude toward life.[3]

More broadly, scholars in the field define aesthetics as "critical reflection on art, culture and nature".[4][5] In modern English, the term aesthetic can also refer to a set of principles underlying the works of a particular art movement or theory: one speaks, for example, of the Cubist aesthetic.[6]
