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.
