" Madness and passion have always been interchangeable. Throughout the entire western literary tradition. Madness is an abundance of existence. Madness is a way of asking difficult questions. What did he mean, the powerless tyrant king? O Fool, I shall go mad.
Maybe madness is the excess of possibility,.... And writingis about reducing possibility to ne idea, one book, one sentence, one word. Madness is a form of self-expression. It is the opposite of creativity. You cannot make anything that can be separated from yourself if you are mad. And yet, look at Rimbaud -- and your wonderful Christopher Smart. But don't harbour any romantic ideas about what it means to be mad. My language was my protection, my guarantee against madness and when there was no one to listen my language vanished along with my reader. "
