And if there is nothing intrinsically wrong with contraceptive intercourse, and if it could become general practice everywhere when there is intercourse but ought to be no begetting, then it’s very difficult to see the objection to this morality, for the ground of objection to fornication and adultery was that sexual intercourse is only right in the sort of set-up that typically provides children with a father and mother to care for them. If you can turn intercourse into something other than the reproductive type of act (I don’t mean of course that every act is reproductive any more than every acorn leads to an oak-tree but it’s the reproductive type of act) then why, if you can change it, should it be restricted to the married? Restricted, that is, to partners bound in a formal, legal, union whose fundamental purpose is the bringing up of children? For if that is not its fundamental purpose there is no reason why for example "marriage" should have to be between people of opposite sexes. But then, of course, it becomes unclear why you should have a ceremony, why you should have a formality at all. And so we must grant that children are in this general way the main point of the existence of such an arrangement. But if sexual union can be deliberately and totally divorced from fertility, then we may wonder why sexual union has got to be married union. If the expression of love between the partners is the point, then it shouldn’t be so narrowly confined.
The only objection, then, to the new heathen, contraceptive morality will be that the second condition I mentioned – near-universality of contraception where there ought not to be begetting – simply won’t be fulfilled. Against the background of a society with that morality, more and more people will have intercourse with little feeling of responsibility, little restraint, and yet they just won’t be so careful about always using contraceptives. And so the widespread use of contraceptives naturally leads to more and more rather than less and less abortion (The exception to this in the short term is where abortion has been encouraged and contraceptives not available, making contraceptives available then produces an immediate but only temporary reduction in abortions.) Indeed, abortion is now being recommended as a population control measure – a second line of defence.
Now if this – that you won’t get this universal “taking care” – is the only objection then it’s a pretty miserable outlook. Because, like the fear of venereal disease, it’s an objection that’s little capable of moving people or inspiring them as a positive ideal of chastity may.
