''Consider the capacity of the human body for pleasure. Sometimes, it is pleasant to eat, to drink, to see, to touch, to smell, to hear, to make love. The mouth. The eyes. The fingertips. The nose. The ears. The genitals. Our voluptific faculties (if you will forgive me the coinage) are not exclusively concentrated in these places, but it is undeniable that they are concentrated here. The whole body is susceptible to pleasure, but in places there are wells from which it may be drawn up in greater quantity. But not inexhaustibly. How long is it possible to know pleasure? Rich Romans ate to satiety, and then purged their overburdened bellies and ate again. But they could not eat for ever. A rose is sweet, but the nose becomes habituated to its scent. And what of the most intense pleasures, the personality-annihilating ecstasies of sex? ... Even if I were a woman, and could string orgasm on orgasm like beads upon a necklace, in time I should sicken of it. Yet consider. Consider pain. Give me a cubic centimeter of your flesh and I could give you pain that would swallow you as the ocean swallows a grain of salt. And you would always be ripe for it, from before the time of your birth to the moment of your death. We are always in season for the embrace of pain. To experience pain requires no intelligence, no maturity, no wisdom, no slow working of the hormones in the moist midnight of our innards. We are always ripe for it. All life is ripe for it. Always. ... Consider the ways in which we may gain pleasure. Consider. Consider the ways in which we may be given pain. The one is to the other as the moon is to the sun.''
