Representation is a rebellion against the realities.
Photography can never depict even or hell, because any drawing is more talkative.
Edward Munch, But art history is long, and complex processes can be at play.
Art is a part of the rebellion against the realities of its unfulfilled desire and low self-worth.

Stephen Hicks, Idealism in art is the meaning of everything.
