“This last chapter .. may have given the impression that somehow man is the ultimate triumph of evolution, that all these millions of years of development have had no purpose other than to put him on earth. There is no scientific evidence whatever to support such a view and no reason to suppose that our stay here will be any more permanent than that of the dinosaur.”

“That no government, so called, can reasonably be trusted, or reasonably be supposed to have honest purposes in view, any longer than it depends wholly upon voluntary support.”

“Now I know that our world is no more permanent than a wave rising on the ocean. Whatever our struggles and triumphs, however we may suffer them, all too soon they bleed into a wash, just like watery ink on paper.”

“There is no scientific study more vital to man than the study of his own brain. Our entire view of the universe depends on it.”

“I have had more trouble with myself than with any other man I have ever met.”

“A writer - and, I believe, generally all persons - must think that whatever happens to him or her is a resource. All things have been given to us for a purpose, and an artist must feel this more intensely. All that happens to us, including our humiliations, our misfortunes, our embarrassments, all is given to us as raw material, as clay, so that we may shape our art.”
