Freud was dying of cancer, not far from this pub actually, yet he refused morphine. He wanted to continue to work and didn’t want to have his mind clouded. If you believe that pleasure, or at least the absence of pain, is man’s highest ideal, then Freud’s decision made no sense. Yet happiness, as Tim sees it, is more than simply an uninterrupted series of pleasurable moments, and that’s a point he feels the positive-psychology movement misses.
