“A great writer is always like a foreigner in the language which he expresses himself, even if this is his native tongue. At the limit, he draws his strength from a mute and unknown minority that belongs only to him. He is a foreigner in his own language: he does not mix another language with his own language, he carves out a nonpreexistent foreign language within his own language. He makes the language itself scream, stutter, stammer, or murmur.”
