Aesthetics or esthetics (also spelled asthetics) is commonly known as the study of sensory or sensori-emotional values,
sometimes called judgments of sentiment and taste. More broadly, scholars in the field define aesthetics as "critical reflection on art, culture and nature." Aesthetics is a subdiscipline of axiology, a branch of philosophy,
and is closely associated with the philosophy of art.
Aesthetics studies new ways of seeing and of perceiving the world.
