“Here is something I have learned the hard way, but which a lot of well-meaning people in the West have a hard time accepting: All human beings are equal, but all cultures and religions are not. A culture that celebrates femininity and considers women to be the masters of their own lives is better than a culture that mutilates girls' genitals and confines them behind walls and veils or flogs or stones them for falling in love. A culture that protects women's rights by law is better than a culture in which a man can lawfully have four wives at once and women are denied alimony and half their inheritance. A culture that appoints women to its supreme court is better than a culture that declares that the testimony of a woman is worth half that of a man.”

Playboy interview (1973)
Context: I've often thought there ought to be a manual to hand to little kids, telling them what kind of planet they're on, why they don't fall off it, how much time they've probably got here, how to avoid poison ivy, and so on. I tried to write one once. It was called Welcome to Earth. But I got stuck on explaining why we don't fall off the planet. Gravity is just a word. It doesn't explain anything. If I could get past gravity, I'd tell them how we reproduce, how long we've been here, apparently, and a little bit about evolution. I didn't learn until I was in college about all the other cultures, and I should have learned that in the first grade. A first grader should understand that his or her culture isn't a rational invention; that there are thousands of other cultures and they all work pretty well; that all cultures function on faith rather than truth; that there are lots of alternatives to our own society. Cultural relativity is defensible and attractive. It's also a source of hope. It means we don't have to continue this way if we don't like it.

"Peace is not a natural state of man, as the great pacifist Gandhi told us. But man can create it. If we have broken down walls that seemed unbreakable, we will not passively agree that more profound differences should their place."
