And you may wonder, OK, that's all fine, sounds great -- moral direction in history -- but what about this so-called clash of civilizations? Well, first of all, I would emphasize that it fits into the non-zero-sum framework, OK. If you look at the relationship between the so-called Muslim world and Western world -- two terms I don't like, but can't really avoid; in such a short span of time, they're efficient if nothing else -- it is non-zero-sum. And by that I mean, if people in the Muslim world get more hateful, more resentful, less happy with their place in the world, it'll be bad for the West. If they get more happy, it'll be good for the West.
