I like nature but not its substitutes. Naturalist art, illusionism, is a substitute for nature. I remember that in arguing with Piet Mondrian (in Paris 1920's), he opposed art to nature saying that art is artificial and nature is natural. I do not share this opinion. I do not think that nature is in natural opposition to art. Art's origins are natural.
