"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. You spoke of ‘infinity’ as if it were a number. It’s not. You may as well ask, 'What is truth divided by beauty?’ I have no clue. I only know how to divide numbers. ‘Infinity,’ ‘truth,’ ‘beauty’—those are not numbers.”"

"This is life. People stumble and grope blindly hither and thither, wondering if they did the right thing, occasionally knocking something over and hoping no-one noticed, striving for illusory goals, addled with guilt and insecurity."

"Wherever there is a jackboot stomping on a human face there will be a well-heeled Western liberal to explain that the face does, after all, enjoy free health care and 100 percent literacy."

"The fact is that political stupidity is a special kind of stupidity, not well correlated with intelligence, or with other varieties of stupidity."

"Marriage is one of those things that works best when people don’t think about it too much."

"American society is increasingly a conspiracy of the smart against the dumb."

"Stereotypes are, in fact, merely one aspect of the mind’s ability to make generalizations, without which science and mathematics, not to mention much of everyday life, would be impossible."

"Most people are not intellectuals — a fact that intellectuals have terrible trouble coming to terms with."

"The USA — and, to a much worse degree, Western Europe and Japan — have low birth rates, below replacement level. Poorer countries in Latin America, Africa, and the Middle East also have dropping birth rates; but their birth rates have only just started to drop, while ours have been falling for decades. So we are, or soon shall be, running out of people; they have people to spare. The easy and obvious answer, if we want to keep our populations stable, is to let people from those poorer, more philoprogenitive countries, come and live in ours. Hence the mass immigration that has been a feature of the advanced world — except for Japan — this past few decades. The trouble is, these policies are premised on the Multicultural Theorem; i.e. that masses of people of different races, from different places, practicing different folkways and religions, carrying various kinds of intercultural and interracial grievances, can live together in one country in reasonable harmony. Unfortunately no-one has bothered to prove the Multicultural Theorem; and the evidence is mounting that it may actually turn out to be false."
