Wise men, when in doubt as to whether to speak or remain silent, give themselves the benefit of the doubt by keeping quiet.
Be silent, if you choose; but when it is necessary, speak—and speak in such a way that people will remember it.
In order to speak about all and to all, one has to speak of what all know and of the reality common to us all. The sea, rains, necessity, desire, the struggle against death-these are the things that unite us all.
I have a horror of people who speak about the beautiful. What is the beautiful? One must speak of problems in painting!
