Natural Law, Animals, and Purposes
Jason Kuznicki on Mar 22nd 2007
Commenter JC writes as follows:
Natural law has nothing to do with “what animals do.” And I always question the “gay” interpretations of animal behavior (e.g., people argue that dogs “humping” each other is “homoerotic,” yet dogs do not ejaculate except for a female in heat).
Natural Law has to do with examining the intent and purpose of an action. E.g,. eating is for nutrition *first*. Yes, eating is pleasurable, but if we ate only for pleasure, we’d all end up 300 lbs, toothless, and dying of massive coronaries at 25. Our “health” movement is a perfect example of natural law: eating is for nutrition first. You look at the nutritional value of the food, *then* at its pleasurable taste.
The same holds for sexual intercourse. The primary purpose is procreation; unity and pleasure are secondary.
First of all, homosexual acts among animals commonly produce ejaculation (No, I never thought I’d have to argue this point, either):
Geist (1974) in his mountain sheep demonstrates that male-male mounting is a “normal” part behavior and happens frequently. When a dominant ram is courting and copulating with an estrous ewe, the subordinate males become excited and mount each other indiscriminately. Geist counted sixty-nine male homosexual mounts out of one hundred encounters in such a situation. Feral goats show the same behavior. Rams may ejaculate at any time during the year in homosexual interaction.
Even if gay animals didn’t couple to the point of ejaculation, what would the reasoned conclusion be? That lifelong, exclusively homosexual love would be natural, so long as we just humped each others’ legs and no one had an orgasm? I somehow doubt that Christian conservatives would agree.
Now, as to the old Thomistic saw of primary purposes…
Suppose I told you that the primary purpose of reading is to gain knowledge. You would probably agree.
So what do we do with Shakespeare, whom we read chiefly for his aesthetic merit and almost never for the knowledge that we gain? Is reading Shakespeare illegitimate or immoral, because it deviates from the primary purpose of reading?
The very idea that any general category of action must always have one primary purpose is a bit of pedantry that even this Aristotelian must strongly reject. That any specific action must have a primary purpose seems reasonable enough — but that a whole class of actions, or that many different performances of the same action, must always have the same purpose, is ridiculous. Even within a specific type of action, as it were, multiple purposes may exist.
If I deposit a large jar of change at the bank, my primary purpose may be to rid myself of clutter in the house. A secondary purpose might be to free up the jar for another use. A third might purpose be to have more money in my bank account. Are these second and third purposes illegitimate? Should I feel guilty or ashamed that I enjoy having achieved them, too? Certainly not.
Now, what if I didn’t care very much about how cluttered my house was, and if I didn’t really need the money, but I highly valued the use of the jar? And what if I was broke, and I needed cash in my bank account, but a tidy house and an extra jar were merely a couple of fringe benefits?
Any one of these could be the primary purpose of the very same action. In no case would the other purposes become wrong, whether for me or for anyone else. The same is true of sexual acts, which may have many different purposes. They may satisfy a purely biological urge, or express a lifelong romantic devotion, or be the start of a hoped-for new life. They may even express hatred or contempt, as in the case of rape.
Why don’t we just take the commonsense approach, and confine ourselves to moral analysis of these purposes in themselves, and of the harm or the good that the action may do? Here’s another bit of Thomism for all of you natural-law types:
…just as the primary goodness of a natural thing is derived from its form, which gives it its species, so the primary goodness of a moral action is derived from its suitable object: hence some call such an action “good in its genus”; for instance, “to make use of what is one’s own.” And just as, in natural things, the primary evil is when a generated thing does not realize its specific form (for instance, if instead of a man, something else be generated); so the primary evil in moral actions is that which is from the object, for instance, “to take what belongs to another.” And this action is said to be “evil in its genus,” genus here standing for species, just as we apply the term “mankind” to the whole human species.
It stacks the deck inappropriately to crown one purpose “primary” and to judge all the others as immoral, particularly when this reasoning is divorced from all thought of real-world outcomes. As I understand it, this is the way that Aquinas would have us judge natural phenomena — not questions of moral action.
Natural phenomena, which have one definite end, must be judged good or bad solely on whether they achieve that end: A person may be born with genetic defects or other handicaps, or not, and we would call the former bad, while calling the latter good. Actions, however, can aim at many different things — so we must judge them first of all by their aims. “To have sexual intercourse” can be a supremely virtuous action, or an utterly depraved one. What matters is the end in mind. If we are concerned with the status of a moral action, let us use the criteria that Aquinas laid out for judging moral action — and not the criteria that Aquinas laid out for judging natural phenomena.
Now, one may argue that the aim of true love is never served by homosexual actions, but this is entirely different from what most the natural rights theorists say about homosexuality. Instead, they argue — as JC does above — that the primary purpose of sexual intercourse is reproduction, not love, and they proceed to judge all sexual acts based on how close they come to achieving that aim. This isn’t even Thomism. It’s sophistry.
In short, my problem with Thomistic natural law thinkers is not that they use medieval philosophy against gays and lesbians. It’s that they haven’t even read their own medieval philosophy, which despite its age and its technical prose offers undreamed of possibilities for freedom, dignity, and love.

Ughh . . . want . . . to . . . vomit . . . teleologico-metaphysico-nonsense overload (not directed at your post, Dr. Kuznicki, but at the silly argument you are debunking).
Look, in biology there is no such thing as “purpose”. There are only outcomes. Evolution is not directed, and neither is the life of an organism. Individual organisms can do whatever they want with all of the adaptations and spandrels they formed with. Some of these things will be pleasurable, some won’t. Some actions are possible, others aren’t. Some will lead to reproduction, others won’t. So what? Studying for an MBA, eating sorbet, and masturbating aren’t “natural” either. Time to ban these?
Excellent post, Jason.
There is another way in which arguments of this sort tend to overlook basic traditional distinctions in natural law theory. Aquinas, to take the most convenient example, distinguishes between natural laws that are individual-directed and natural laws that are species-directed. This comes out very clearly in his discussion of manual labor. Thomas holds that it is a precept of natural law that we should engage in manual labor (in a broad sense of the term, involving any working with the hands) to support ourselves. But this is a natural law governing the species: the human race, in general, should be doing the manual labor required to support all its members. This does, in fact, set up a sort of presumption that we should all be doing the work required to support ourselves. However, this is only ceteris paribus. Individuals may have very good reasons for not doing it — for instance, they may be called to a form of non-manual labor that enriches everyone, like teaching, that makes it difficult to do the sort of manual labor involved in supporting oneself and those in need. The requirement that we work to support ourselves is a species-level requirement of practical reason, not an individual-level requirement.
Aquinas is very clear that sex for procreation is a species-level dictate of practical reason. This does set up a presumption or preference in favor of sexual activity that’s procreative in general; sex is a procreative function in general, whatever else it may also be. But individual cases are different, and particular individuals may have good reason for sex that they know very well will not result in procreation. And everyone, in fact, recognizes at least some cases like this.
So even if sex’s only general purpose were procreative — something no one usually wants to concede — the argument still wouldn’t be strong enough; because the procreative end of sex has to be an end of sexual activity in general, there would be a general presumption against non-procreative sex, but not one that could rule out the possibility of individuals having good reasons to reject the presumption in their particular case, just as a particular teacher have good reasons to regard her particular work of teaching as something that might reasonably done instead of manual labor, despite the general precept that everyone should do the work required to support themselves and their dependents. And that’s the strongest it seems one could argue for on this line of thought — and even that ceteris paribus principle depends on a premise that is far stronger than most people want to concede.
One of the things I dislike about this general line of argument is that it overlooks the fact that natural law reasoning is hard; good practical reasoning is a lot of work, because it can’t rely too much on idealizations, it deals with things that are highly variable and contingent, and it has to recognize that slight changes in circumstances can sometimes make big differences. This type of argument, though, is trying to short-circuit the whole thing.
