 We are so constructed that the feeling of pleasure is inevitable in certain situations: sexual intercourse, eating delicious food, and the like. If sexual pleasure in marriage is not sinful, then the pleasure itself, inside or outside of marriage, is not sinful; if it is sinful, then marriage cannot sanctify it—and if the conclusion were drawn that such acts should be performed wholly without pleasure, then Abelard declares they cannot be done at all, and it was unreasonable (of God) to permit them only in a way in which they cannot be performed.
