To struggle against censorship, whatever its nature, and whatever the power under which it exists, is my duty as a writer, as are calls for freedom of the press. I am a passionate supporter of that freedom, and I consider that if any writer were to imagine that he could prove he didn't need that freedom, then he would be like a fish affirming in public that it didn't need water.
