“If you paint the leaf on a tree without using a model, your imagination will only supply you with a few leaves; but Nature offers you millions, all on the same tree. No two leaves are exactly the same. The artist who paints only what is in his mind must very soon repeat himself.”

“When facing a single tree, if you look at a single one of its red leaves, you will not see all the others. When the eye is not set on one leaf, and you face the tree with nothing at all in mind, any number of leaves are visible to the eye without limit. But if a single leaf holds the eye, it will be as if the remaining leaves were not there.”

“In a forest of a hundred thousand trees, no two leaves are alike. And no two journeys along the same path are alike.”

“all conservatism is based upon the idea that if you leave things alone you leave them as they are. But you do not. If you leave a thing alone you leave it to a torrent of change. If you leave a white post alone it will soon be a black post. If you particularly want it to be white you must be always painting it again; that is, you must be always having a revolution. Briefly, if you want the old white post you must have a new white post.”

“Only a friend or a giraffe would stick his neck out for you. But only a giraffe would eat all the leaves off your tree so he could peek in your second story bedroom window.”

“Where there is a true art and genuine virtuosity the artist can paint an incomparable masterpiece without leaving even a trace of his identity.”
