In aesthetics, the concept of taste has been the interest of philosophers such as Plato, Hume, and Kant. It is defined by the ability to make valid judgments about an object's aesthetic value. However, these judgments are deficient in objectivity, creating the 'paradox of taste'. The term 'taste' is used because these judgments are similarly made when one physically tastes food.

Aesthetics is the branch of philosophy concerned with the nature of beauty and the nature of taste; and functions as the philosophy of art. Aesthetics examines the philosophy of aesthetic value, which is determined by critical judgements of artistic taste; thus, the function of aesthetics is the "critical reflection on art, culture and nature".
