I've never been an optimist but that's fine because pessimists have the possibility of being agreeably surprised, and that's a reason for being pessimistic, but I've always defended a certain kind of pessimism because what is known as optimism is really a collection of illusions and I think one must recognise what all religious people know, which is that human beings are imperfect and fallen and there's no way in which they can alone surmount the problems which they themselves create.
