The style arises out of the interplay between the world and ourselves, or more specifically, between the spirit of the time and the artist. The spirit of a time is probably a fact as objective as any fact in natural science, and this spirit brings out certain features in the world.… The artist tries in his work to make these features understandable, and in this attempt he is led to the forms of the style in which he works. Werner Heisenberg, Physics and Philosophy
