There is a difference if we see something with a pencil in our hand or without one.

History justifies whatever we want it to. It teaches absolutely nothing, for it contains everything and gives examples of everything.

To be sincere means to be the same person when one is with oneself; that is to say, alone - but that is all it means.

The advantage of the incomprehensible is that it never loses its freshness.

Nothing is more natural than mutual misunderstanding; the contrary is always surprising. I believe that one never agrees on anything except by mistake, and that all harmony among human beings is the happy fruit of an error.

Every beginning is a consequence - every beginning ends some thing.

Everything changes but the avant-garde.
