An expression of ideas that provokes one's thought. Art is the Godhead revealed through the works of man. Art is the process or the result of defining an emotional or physical state of being. Art is a spirit that comes from within. Only seeing what one has known before.
Art is useless activity that makes a difference.
I would like to quote from R. G. Collingwood, The Principles of Art. The artist must prophesy not in the the sense that he foretells things to come, but in the sense that he tells his audience, at risk of their displeasure, the secrets of their own hearts. His business as an artist is to speak out, to make a clean breast. But what he has to utter is not, as the individualistic theory of art would have us think, his own secrets. As spokesman of his community, the secrets he must utter are theirs.
