Nonmathematical people sometimes ask me, “You know math, huh? Tell me something I’ve always wondered, What is infinity divided by infinity?” I can only reply, “The words you just uttered do not make sense. That was not a mathematical sentence.

I only know how to divide numbers. ‘Infinity,’ ‘truth,’ ‘beauty’—those are not numbers.”

After the many hundreds of generations that Australian, East Asian, African, European and indigenous American populations of Homo sapians developed in isolation from each other, in different environments, there ought to be divergence aplenty, though nowhere near to speciation. And so there is. That is why a roomful of Australian aborigines looks nothing like a roomful of Hungarians, and neither looks anything like a roomful of Quechua-speaking South American indigenes.

I have never read the Koran and at this point I most likely never shall. It looks really boring. I can’t offer an informed opinion about Islam, any more than 99.9 percent of other Americans can. I certainly don’t wish any harm to Muslims in general. Jolly good luck to them all. Hate? Not here. But it is surely obvious that if you let masses of Muslims settle in your non-Muslim country, you’ve gotten yourself some frictions and problems you didn’t have before. Why bring such troubles on yourself?
