Finnis’ natural law theory seems to say that “procreation” is the “basic value” at which an act of sexual intercourse naturally aims. This seems to mean that the natural purpose of sexual intercourse is procreation. So anything that prevents an act of sexual intercourse from achieving its natural purpose of procreation is morally wrong. What are the differences between this natural law theory of John Finnis and Aquinas’ natural law theory? What are the similarities? Is either theory correct? Why?
