Aesthetics

http://en.wikipedia.org/wiki/Aesthetics

Aesthetics (also spelled æsthetics) is a branch of philosophy dealing with the nature of beauty, art, and taste, with the creation and appreciation of beauty.[1] [2] It is more scientifically defined as the study of sensory or sensori-emotional values, sometimes called judgments of sentiment and taste.[3] More broadly, scholars in the field define aesthetics as “critical reflection on art, culture and nature.”[4][5]
