There Are Only Four Pro-Choice Arguments

Eamonn Clark, STL

Naturally, being a moralist who is active in western society, I have encountered and thought a lot about various arguments in favor of the “pro-choice” position. Summarizing all of the arguments, we find that there are really only four; while they can be mixed together, they are nonetheless discernible in basically every argument ever made in favor of the “right” to have an abortion, or that abortion is morally acceptable. And yes, they are each erroneous. Let’s go through them: they are the physical (or biological) error, the metaphysical error, the ethical error, and the metaethical error.

The Physical Error

The first error is that the fetus is not a distinct living organism. Any biologist can debunk this. If the fetus is not a distinct living organism, there is no such thing. It is true that there is a physical connection through the umbilical cord, but first of all, the zygote pre-existed this stage, and second of all, we acknowledge that the cord actually connects two organisms, each of which exhibit the standard signs of biological life: homeostasis, cellular organization, metabolism, reproductive capacity (actual in the zygotic phase when asexual reproduction can occur, potential in the fetal stage as sexual reproduction), response to stimuli, growth, heredity… There is simply no argument to be made here. The advocate of abortion who is taken by this error would be forced to admit that a pregnant woman has eight limbs, two heads, and maybe male reproductive organs, which she then ceases to have upon delivering a child. There is no point in arguing with someone who will not budge on this. However, if we say this is a distinct living organism, we admit that to abort it is to kill it.

The Metaphysical Error

The second error is that the distinct living organism is not a human (or a person). The advocate will say that eventually the organism will become a human, based on certain actions or activated capacities – cognition (but usually excluding sleepers, for reasons inexplicable), self-reliance (of a high-level, let it be noted), capacity to be a productive member of society (whatever that means)… These are signs of humanity, it is true. However, to say that these are constitutive of humanity is quite problematic. First of all, most would agree that we are human beings, not human doings – that is to say, we can do human things because we are actually humans first. (Agere sequitur esse, as the axiom goes – action follows being.) Second, if we define humanity based on certain kinds of actions, we must ask, why is it these actions which are characteristics of humanity and not other actions? And why should it be actions at all? Why not “traits,” like race or sex or eye color? Of course, some do in fact say that something as arbitrary as “3 months” or “being outside the womb” in fact turns the very same living organism into a human being. Plenty will say that it is a “capacity to feel pain,” sometimes mixed with “capacity for memory,” which typically ignores folks with congenital analgesia – the chronic inability to feel pain – and is also simply based on the emotional discomfort coming from an empathetic impulse). Strange… We can see the problem – once we detach the definition of humanity from “being,” as a substance, we are left with arbitrary values leading to arbitrary norms. (A substance is that which is not predicated of another – we do not say “human” of anything, but we do say “cognition” or “race” of a human.) So, to the point: it is the same being (the same living organism!) which is thinking and feeling and “self-relying” that is growing in the womb. What changes are traits and actions – size, strength, organ development, mental activity, mobility, etc. The “being” does not change – it is the same substance. It is a human being who is simply not doing the most human-like things at this moment. This error is the most prevalent and most difficult to get one to see the problems of. But if we admit the metaphysical reality of humanity in the fetus, we are forced to conclude that aborting the fetus is murder.

The Ethical Error

The third error – and perhaps the most repulsive – is that one is never bound to suffer for another individual human being. We’ve shown that biology says that the fetus is not “my body,” but why not still have “my choice” despite that? “So, it is a human being, who cares? This person is inconvenient for my life.” Well, it could be true. However, if a mother is not bound to suffer for her own child, and, what is more, in the precise way that the woman exists as such, namely, to generate life and gestate that life within herself, one could hardly ever be bound to suffer for another. This seems to eliminate all moral responsibility of any kind, or it at least comes very close. In the case that the advocate bites this bullet, he is simply a terrible person and is unlikely to be persuaded by anything one can say. The problem with the ethical error is grasped intuitively by most – this error is therefore quite rare in its pure form. It does show up in weaker forms, however, in the context of diminishing the humanity of the fetus, as described above. It is much easier to argue that one is not obliged to suffer for a pre-human than for a human…

The Metaethical Error

The final error is the rejection of the possibility of real moral obligations altogether. (“Metaethics” is the branch of ethics which asks or studies “what do we mean by ‘ethics’ in the first place?”) The error here is to relegate all ethical norms to the dictates of individual wills (namely, one’s own, or perhaps the “will of the people/government”). The only question then is about strategy – how to get what you want. Plato’s famous thought experiment in the Republic addresses this head-on… The one who wears the Ring of Gyges could get away with anything (yes – exactly like the One Ring to rule them all). Do moral laws really apply to such a person when he is wearing the ring? Let’s say yes, it is still “good” to follow the moral law. Then we can ask with Nietzsche, “Why be good?” The entire meaning of morality collapses in on itself. “Autonomous” morality is no morality at all. This includes every kind of utilitarianism and consequentialism in the strict sense. Who gets to determine what counts as “utility”? And how would we even know how to reach maximum utility anyway? These are the first problems. (Consequentialism is worth its own post.) At the end of the day, we are left with one’s own values being imposed on others, with nothing to do but play power games to achieve what makes us feel warm and fuzzy by making “contracts” and playing nice. And the unborn are powerless.

These four arguments can be combined in various ways. But they are always there. For example, the famous “violinist” example of Thomson commits the ethical error indirectly. Perhaps we don’t have to suffer for a famous violinist who is artificially connected with our body – but a mother does have to suffer for her own child who is naturally connected with her body by the very fact of womanhood’s intrinsic order, namely, generation of new life within the body.

The point of ethics is not merely avoiding wrongdoing, it is fundamentally about achieving happiness through flourishing – which entails the faculties of human nature striving moderately in accord with the order of reason toward their proper ends. Killing innocent children does not lead to such flourishing, as we are intrinsically ordered towards life in community in a common pursuit of the truth – it is one of the primordial precepts of the natural law. Abortion is immoral, and it will never make a person truly happy. And we see this validated by the fact that so few parents regret having any of their children, while the opposite claim does not hold.

Comet and Cupid

The 67P/Churyumov-Gerasimenko Comet (or “Rosetta’s Comet”) has been found to have organic elements on board. That’s quite a discovery, but how much bigger would it have been if the Mars Rover had found a little clump of algae?

There’s an entire industry around extraterrestrial life. One can just imagine with what care and reverential fear the world’s scientists would handle (or even discuss) some Petri dish of alien amoebas. How many billions of dollars would go to the protection, preservation, and cultivation of that life?

Meanwhile, it’s springtime, and you know what that means: hormones. And we all know hormones lead people to make dumb choices.

Nobody seems to care so much about destroying human life in the womb, even though it behooves us far more to protect our own kind than to grovel over some alien fungus. Space-grass won’t take care of you when you’re old. It will never look you in the eye and tell you it loves you. And no matter how hard you try, you will not be able to teach it how to ride a bike. The list goes on.



Yes, aliens. But yes, humans, too. Shouldn’t we be our first priority? Shouldn’t we figure out how to flourish on our own before trying to flourish as an inter-galactic community?

The drive to search for space-buddies isn’t as strong as the drive for human intimacy. And no matter how many remakes there are of War of the Worlds, the prospect of having a child is more threatening. So we cheat the system.

Pfft. Puny humans.

Although this is less ridiculous than the fact that the destruction of the eggs of endangered turtles carries a higher penalty than the destruction of your own child. At least aliens are cool… No offense to the hawksbill turtle.

One last question… If there really is intelligent extraterrestrial life, and they know anything about our planet, why exactly would they want to have anything to do with us?
