“A pessimist is a man who thinks everybody is as nasty as himself, and hates them for it.”

As quoted in "The Joking Troubadour of Gloom" in The Daily Telegraph (26 April 1993) http://www.webheights.net/speakingcohen/feb93.htm
Context: I am so often accused of gloominess and melancholy. And I think I'm probably the most cheerful man around. I don't consider myself a pessimist at all. I think of a pessimist as someone who is waiting for it to rain. And I feel completely soaked to the skin. … I think those descriptions of me are quite inappropriate to the gravity of the predicament that faces us all. I've always been free from hope. It's never been one of my great solaces. I feel that more and more we're invited to make ourselves strong and cheerful..... I think that it was Ben Jonson who said, I have studied all the theologies and all the philosophies, but cheerfulness keeps breaking through.

Context: There is no hate without fear. Hate is crystallized fear, fear's dividend, fear objectivized. We hate what we fear and so where hate is, fear will be lurking. Thus we hate what threatens our person, our liberty, our privacy, our income, our popularity, our vanity and our dreams and plans for ourselves. If we can isolate this element in what we hate we may be able to cease from hating. Analyse in this way the hatred of ideas or of the kind of people whom we have once loved and whose faces are preserved in Spirits of Anger. Hate is the consequence of fear; we fear something before we hate; a child who fears noises becomes the man who hates them.
