Art is not merely an imitation of the reality of nature, but in truth a metaphysical supplement to the reality of nature, placed alongside thereof for its conquest.

What goes on in abstract art is the proclaiming of aesthetic principles... It is in our own time that we have become aware of pure aesthetic considerations. Art never can be imitation.
