In comparing an alien culture with one’s own, one is forced to ask oneself questions more fundamental than any that usually arise in regard to home affairs. One is forced to ask: What are the things that I ultimately value? What would make me judge one sort of society more desirable than another sort? What sort of ends should I most wish to see realized in the world? Different people will answer these questions differently, and I do not know of any argument by which I could persuade a man who gave an answer different from my own. I must therefore be content merely to state the answer which appeals to me, in the hope that the reader may feel likewise.
