Beauty in art can be difficult to put into words due to a seeming lack of accurate language.
There is a basic human instinct, an internal appreciation, for harmony, balance, and rhythm; this can be defined as beauty.
Aesthetics is the branch of philosophy that deals with the nature and appreciation of art, beauty, and taste; aesthetics is central to any exploration of art.
For Immanuel Kant, the aesthetic experience of beauty is a judgment of a subjective, but common, human truth.
For Arthur Schopenhauer, aesthetic contemplation of beauty is the freest and most pure and truthful that intellect can be, and is therefore beautiful.
An aesthetic judgment cannot be an empirical judgment but must instead be processed on a more intuitive level.
