It is to be remembered that all art is magical in origin - music, sculpture, writing, painting - and by magical I mean intended to produce very definite results. Paintings were originally formulae to make what is painted happen. Art is not an end in itself, any more than Einstein's matter-into-energy formulae is an end in itself. Like all formulae, art was originally FUNCTIONAL, intended to make things happen, the way an atom bomb happens from Einstein's formulae.
