representation is a rebellion against the realities.
Photography can never depict even or hell, because any picture 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. The roots of scientific inquiry are curiosity and skepticism. Realism is like idealism, but a kind of idealism less idealistic than usual. Realism dealing with the brick and mortar world is the bread-and-butter of interesting artworks.
Mundane details are omitted for the sake of clarity. Realism in art is not scientific accuracy.
The driving purpose of contemporary realism is not to do art but to find out what art is really. Mundane considerations are essential to the development of playful realism and chance. The contemporary realists often used mundane subject matter for their paintings.
Stephen Hicks, Idealism in art is the meaning of everything.
