But would you kindly ponder this question: What would your good do if evil didn't exist, and what would the earth look like if all the shadows disappeared? After all, shadows are cast by things and people. Here is the shadow of my sword. But shadows also come from trees and living beings. Do you want to strip the earth of all trees and living things just because of your fantasy of enjoying naked light? You're stupid.
Mikhail BulgakovTo 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.
