I could never mix in the common murmur of the rising generation against monogamy, because no restriction on sex seemed so odd and unexpected as sex itself. To be allowed, like Endymion, to make love to the moon and then to complain that Jupiter kept his own moons in a harem seemed to me (bred on fairy tales like Endymion’s) a vulgar anticlimax. Keeping to one woman is a small price for so much as seeing one woman. To complain that I could only be married once was like complaining that I could only be born once. It was incommensurate with the terrible excitement of which one was talking. It showed, not an exaggerated sensibility to sex, but a curious insensibility to it. A man is a fool who complains that he cannot enter Eden by five gates at once. Polygamy is a lack of the realization of sex; it is like a man plucking five pears in mere absence of mind.
