The man who has learned that three plus one are four doesn't have to go through a proof of that assertion with coins, or dice, or chess pieces, or pencils. He knows it, and that's that. He cannot conceive a different sum. There are mathematicians who say that three plus one is a tautology for four, a different way of saying "four" ... If three plus one can be two, or fourteen, then reason is madness.

A writer, or any man, must believe that whatever happens to him is an instrument; everything has been given for an end. This is even stronger in the case of the artist. Everything that happens, including humiliations, embarrassments, misfortunes, all has been given like clay, like material for one's art. One must accept it.

Whatever one man does, it is as if all men did it. For that reason, it is not unfair that one disobedience in a garden should contaminate all humanity; for that reason it is not unjust that the crucifixion of a single Jew should be sufficient to save it.

Personally, I am a hedonistic reader; I have never read a book merely because it was ancient. I read books for the aesthetic emotions they offer me, and I ignore the commentaries and criticism.

As the end approaches, there are no longer any images from memory - there are only words.
