Morals from Nature: What about sex?

If Nature, by providing a teleology for Man, is the source of our morality, then what is the morality of sex?

There have been a number of answers to this question over the years. The Catholic Church has articulated a theology of sexuality which is probably familiar in outline to most people: sex is good inside marriage when it is for the sake of begetting children; but sex outside of marriage, or sex acts where children are impossible (think of contraception, masturbation, or many other examples), are "intrinsically disordered" and wrong. What is interesting is that a number of authors who believe they are writing science find themselves in a similar boat for a similar reason: these are the authors who look at sex through the lens of sociobiology or "evolutionary psychology". They seem to have a lot to say about sexual jealousy, differential investments in childrearing, and so on, but to have some trouble accounting for non-procreative sexual activity. And of course the argument would be that non-procreative sexual activity doesn't leave children behind (obviously!) and therefore can hardly be selected-for in any normal Darwinian sense.

What interests me about both these positions is that on the surface they look so logical, but in their consequences they look totally at odds with the way human beings really live -- around the globe and over the ages. What's more, it is easy to think you have found the flaw in the argument and then go astray in another direction.

Both the Catholic and the "evolutionary psychological" positions rest on the premise that the purpose of sex is reproduction. From that, all the rest follows. If you want to reject those conclusions, the easiest way is to reject teleology and say "There are no purposes! Go do what you want!" But you know by now that I consider teleology to be a basic fact about living beings, so that too is an error.

What then?

If an argument leads to results which look absurd, but all the steps of the argument are logical, the error is probably in its premises. As noted, the premise behind both the Catholic and the "evolutionary psychological" teachings is this: Reproduction is the purpose of sex. But where is the error? If we concede that there are purposes in Nature, how can this premise possibly be false? Isn't that how we get children, through sex? Isn't it the only possible way to create new children?

Of course it is. And while I do affirm there is an error in that sentence, it's subtle. Only one word is wrong, and that word is not "reproduction." Its "the."

The point is that this premise ("Reproduction is the purpose of sex") itself relies on an earlier, hidden premise which states, "A thing can have only one purpose." But where is the evidence for that? How would you ever go about proving it? Can you prove it?

Presumably the argument would start by conceding that a thing can be used in lots of different ways, but would insist that only one of them is the true natural end or goal or purpose. A car can be used to get money (by selling it) or to impress your neighbor (by polishing it ostentatiously and parking it where he has to see it); but its natural purpose is to drive. And as far as it goes, the analogy sounds plausible. Does it work the same way in Nature? You could argue that I can use the hair on top of my head to make a political or fashion statement depending on how I wear it, but its natural purpose is to keep my head warm. Maybe the rest of Nature is like that too.

Only it's not. I can formally disprove the allegation that everything has only one purpose, as follows:
Lemma: It is possible for a thing to have more than one natural purpose.  
Proof: For the sake of an example, consider the penis. What is its natural function: elimination of waste, or reproduction of the species? Both are essential to survival. Neither one can possibly be considered an incidental, side use. Neither one can be considered an abuse. Both purposes are absolutely fundamental. But they are different. Therefore it is possible for a thing to have more than one natural purpose. QED.

And with this proof, both the Catholic and the "evolutionary psychological" teachings collapse. Because while it is obvious that reproduction is a purpose of sex, there is no evidence whatever that it is the only one.

What else then? What other purpose can we reasonably suppose sex to have? Recall that I recently argued that the highest end for Man is friendship. And recall the argument I made ... gosh, almost three years ago, by now ... that the purpose of the orgasm is to make love -- to create or generate love even where it did not exist before (and therefore a fortiori to strengthen it where it does). Based on these two arguments, I think it is inescapable that one essential, natural purpose for sex is to bind us together, to help us love each other, to unite us as friends and lovers.

Naturally there are other ways to make friends too. Don't misunderstand me to say sex is the only path to friendship! But it can be one of them.

But if the purpose -- oops, excuse me, one of the purposes -- of sex is friendship and human bonding, then what should the morality of sex look like? Suddenly there is nothing wrong with all the different varieties of non-procreative sex (including contraception, masturbation, and all the others), as long as they are serving the purposes of love and bringing people together. On the other hand, rape is pretty obviously still bad because it takes something that should be a means towards unity and makes it a violent weapon instead.

I don't have a complete teaching to offer about the other consequences of this new understanding. This is new ground, and I am still thinking it through. But I expect the changes to be real, and -- what is more important -- closer in line with our lived human experience than the earlier teachings were.
