Les failles grandissaient, ou plutôt le mur, semblait-il, perdait de lui-même sa solidité sans pour autant cesser d'être opaque, comme s'il s'agissait d'une muraille de fumée au lieu d'une muraille de pierre.(L'abîme)

I think still that someone wiser than I might well have remained happy till his death.

I have come to think that great men are characterized precisely by the extreme position which they take, and that their heroism consists in holding to that extremity throughout their lives.

I don't think I ever relinquish a person I have known, and surely not my fictional characters. I see them, I hear them, with a clarity that I would call hallucinatory if hallucination didn't mean something else ... A character whom we create can never die, any more than a friend can die ... Through [my characters] I've lived many parallel lives.

A touch of madness is, I think, almost always necessary for constructing a destiny.
