I could never mix in the common murmur of that rising generation against monogamy, because no restriction on sex seemed so odd and unexpected as sex itself. … 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 had only been 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.
—From Orthodoxy by G.K. Chesterton, Ch. 4: The Ethics of Elfland
