I do not write this in a spirit of sourness or personal disappointment of any kind, nor do I have any romantic attachment to suffering as a source of insight or virtue. On the contrary, I would like to see more smiles, more laughter, more hugs, more happiness and, better yet, joy. In my own vision of utopia, there is not only more comfort, and security for everyone — better jobs, health care, and so forth — there are also more parties, festivities, and opportunities for dancing in the streets. Once our basic material needs are met — in my utopia, anyway — life becomes a perpetual celebration in which everyone has a talent to contribute. But we cannot levitate ourselves into that blessed condition by wishing it. We need to brace ourselves for a struggle against terrifying obstacles, both of our own making and imposed by the natural world. And the first step is to recover from the mass delusion that is positive thinking.
