Nature is more depth than surface, the colours are the expressions on the surface of this depth; they rise up from the roots of the world.

I could paint for a hundred years, a thousand years without stopping and I would still feel as though I knew nothing.

Painting is damned difficult - you always think you've got it, but you haven't.

I ask you to pray for me, for once age has overtaken us, we find consolation only in religion.

With an apple I will astonish Paris.

Doubtless there are things in nature which have not yet been seen. If an artist discovers them, he opens the way for his successors.

An art which isn't based on feeling isn't an art at all... feeling is the principle, the beginning and the end; craft, objective, technique - all these are in the middle.
