When the moral history of the 1990s is written, it might be titled Desperately Seeking Satan. With peace and harmony ascendant, Americans seemed to be searching for substitute villains. We tried drug dealers (but then the crack epidemic waned) and child abductors (who are usually one of the parents). The cultural right vilified homosexuals; the left vilified racists and homophobes. As I thought about these various villains, including the older villains of communism and Satan himself, I realized that most of them share three properties: They are invisible (you can’t identify the evil one from appearance alone); their evil spreads by contagion, making it vital to protect impressionable young people from infection (for example from communist ideas, homosexual teachers, or stereotypes on television); and the villains can be defeated only if we all pull together as a team. It became clear to me that people want to believe they are on a mission from God, or that they are fighting for some more secular good (animals, fetuses, women’s rights), and you can’t have much of a mission without good allies and a good enemy.

Creating gods who can see everything, and who hate cheaters and oath breakers, turns out to be a good way to reduce cheating and oath breaking.

So, we’ve reached the state that George Will described. He said there’s a certain kind of liberal that wants diversity in everything, except thought. And so, we do need certain kinds of diversity. But the key to remember is that, diversity by its very nature is divisive, and so, what’s the function of your group? If your group needs cohesion, you don’t want diversity. If your group needs good, clear thinking and you want people to challenge your prejudices, then you need it. So in the academic world, we need that kind of diversity, and we don’t have it.
