Defence of Abortion Entails Defence of Infanticide

All arguments used to justify abortion also logically justify infanticide. Pro-abortion arguments such as that rights are acquired rather than inherent, as well as the numerous criteria that have been suggested to qualify for rights (such as achieving a level of rationality or certain physiological characteristics), all apply just as equally to newborn infanticide as they do to abortion.

This means that a defence of abortion logically entails a defence of infanticide. You cannot choose to defend abortion and not defend infanticide without contradiction. This is a matter of fact that influential pro-abortion philosophers explicitly accept. Here are some examples.

In Practical Ethics (1979), Peter Singer readily admits to the logical connection between arguments for abortion and infanticide:

liberals usually hold that it is permissible to kill an embryo or fetus but not a baby. I have argued that the life of a fetus (and even more plainly, of an embryo) is of no greater value than the life of a nonhuman animal at a similar level of rationality, self-awareness, capacity to feel and so on, and that because no fetus is a person, no fetus has the same claim to life as a person. Now we have to face the fact that these arguments apply to the newborn baby as much as to the fetus. A week-old baby is not a rational and self-aware being, and there are many nonhuman animals whose rationality, self-awareness, capacity to feel and so on, exceed that of a human baby a week or a month old. If, for the reasons I have given, the fetus does not have the same claim to life as a person, it appears that the newborn baby does not either. Thus, although my position on the status of fetal life may be acceptable to many, the implications of this position for the status of newborn life are at odds with the virtually unchallenged assumption that the life of a newborn baby is as sacrosanct as that of an adult… I do not regard the conflict between the position I have taken and widely accepted views about the sanctity of infant life as a ground for abandoning my position.

In Abortion and Infanticide (1983), Philosopher Michael Tooley acknowledges that pro-choice arguments are pro-infanticide arguments and he knows that this is a "difficult issue" to accept:

Most current discussions of abortion tend to treat it in isolation from the question of the morality of  infanticide. One of the central contentions to be advanced here is that it is very difficult indeed to arrive at a defensible position on abortion unless one is prepared to come to terms with the difficult issue of the moral status of infanticide.

David Boonin's 1998 book A Defense of Abortion evaluates various arguments in terms of how "attractive" they are to those wanting to defeat rights-based arguments against abortion. Having rejected one suggestion, he considers whether to defend abortion by defending infanticide, but decides that this is not "attractive" since to acknowledge that abortion is on a par with infanticide would delegitimise it:

A defender of abortion …. could agree that you and I have a right to life but deny that newborn infants do. If newborn infants do not have a right to life, then it will again be a simple matter to establish that fetuses lack such a right, and the rights-based argument against abortion will again be defeated. This suggestion is likely to strike most readers as hardly more attractive than the first. In the popular debate about abortion, at least, to say that abortion is morally on a par with killing newborn babies is simply to say that abortion is morally impermissible.

Having accepted that abortion may be on a par with infanticide and that, if so, this would lead many to consider abortion unjustifiable, Boonin chooses to simply ignore this problem without providing any defence or argument:

A number of philosophers, including such prominent figures as Peter Singer and Michael Tooley, have argued that human infants do not have a right to life. And these arguments deserve to be taken seriously on their own terms. But they need not be taken seriously here. For the purposes of this book, arguments for the claim that human infants do not have a right to life can simply be set aside.

Whereas Singer and Tooley at least accepted the logical consequences of their pro-abortion arguments openly, Boonin is less honest. He chooses to "set aside" those logical consequences of his argument that he knows many will find horrific.

The Inconsistency of Pro-Abortion Libertarians

A few oddballs calling themselves libertarians have openly argued for both a pro- abortion and pro-infanticide position. In his 1895 article L'Enfant Terrible, Benjamin Tucker accepted that if one considers abortion justified then one also considers killing a newborn infant justified:

If, then, the child is the mother's while in the womb, by what consideration does the title to it become vested in another than the mother on its emergence from the womb and pending the day of its emancipation? I think that no valid consideration can be shown; and if such is the case, then it is established that the unemancipated child is the property of its mother, of which, by an obvious corollary, she may dispose as freely as she may dispose of any other property belonging to her.

In a 2019 article Abortion and Infanticide a Triple Libertarian and Critical-Rationalist Defence, Jan Lester argues for "the moral permissibility of the abortion and infanticide of unwanted humans" and states that "abortion and infanticide are, in themselves, morally neutral". Although the mind boggles at how anyone can evince such a profound level of moral bankrupcy, he is nonetheless correct when he states that the two positions are inseparable:

It is common, however, for people to accept some versions of these arguments as applied to abortion but reject them as regards infanticide. And that is simply to be logically inconsistent.

Yet this is not the usual stance of pro-choice libertarians. Most libertarian defenders of abortion want to hold the untenable position that abortion is valid but infanticide is not. A common way of attempting to square this circle is to argue that a baby in utero is some kind of aggressor by way of trespass, but this position relies on an unjustifiable denial of causal parental responsibility.

Libertarians who have attempted justifications of this kind include Murray Rothbard, Williamson Evers, and Walter Block. Rothbard's determination to deny causal parental obligations led him to argue the odd position that infanticide is justified if by deliberate starvation but not if by physical assault.

Most other pro-abortion libertarians fail to grapple with the logical implication of their view when it comes to infanticide. Unlike Benjamin Tucker and Jan Lester who say the quiet part out loud– openly advocating infanticide– pro-abortion libertarians usually either ignore their own inconsistency by not talking about infanticide or declare arbitrarily that they do not support it (despite supporting abortion).

If you are pro-abortion, at least have the honesty to accept the logical consequence: all your arguments for abortion also justify infanticide.

The Theory Of Acquired Rights Violates Hoppe's Specificity Principle

Listen to this article
Jake Desyllas

Hans-Herman Hoppe

Libertarians disagree about whether rights are inherent or acquired. In order to judge which theory of rights is valid, both theories must be evaluated against libertarian meta-ethical principles.

A fundamental principle of libertarian meta-ethics is that all property rights must be specific to individuals at definite points in time. This means that any property rule must provide a way to clearly identify the particular individual who has a property right and also provide a way to clearly identify the points in time when this right is valid. Let's call this The Specificity Principle.

Hans-Hermann Hoppe identified this principle. It is one of the meta-ethical principles of his framework of Argumentation Ethics. All the meta-ethical principles put forward by Hoppe in this framework have two key features:

  1. The principle must be accepted in argument, since it is logically derived from the act of argument itself and therefore is undeniable without contradiction:
  2. Any proposed property right is demonstrably unworkable a priori unless it conforms to the principle.

Hoppe showed how both these characteristics apply to the specificity principle:

Nobody can wait and suspend acting until everyone of an indeterminate class of late-comers happens to appear and agree to what one wants to do. Rather, insofar as a person finds himself alone, he must be able to act, to use, produce, consume goods straightaway, prior to any agreement with people who are simply not around yet (and perhaps never will be). And insofar as a person finds himself in the company of others and there is conflict over how to use a given scarce resource, he must be able to resolve the problem at a definite point in time with a definite number of people instead of having to wait unspecified periods of time for unspecified numbers of people. Simply in order to survive, then, which is a prerequisite to arguing in favor of or against anything, property rights cannot be conceived of as being timeless and nonspecific regarding the number of people concerned. Rather, they must necessarily be thought of as originating through acting at definite points in time for definite acting individuals.

The theory of acquired rights is not specific about when a child becomes a self owner

According to the theory of acquired rights, humans only have rights when they possess some characteristic or ability that confers rights-worthiness. However, there is no consensus on what exactly the characteristic or capability is. This fails to comply with the specificity principle because the theory of acquired rights is not specific about when a child becomes a self owner.

The specificity principle states that one must be able to point to a specific owner of a property right at any given time. Yet the theory of acquired rights does not do this. Almost all leading proponents of the theory of acquired rights acknowledge that their theory is ambiguous about when an individual becomes a self owner.

The ambiguity is shown in the way that they defend abortion. Their argument is:

  1. Some abortions are not murder (because the child is not a self owner).
  2. Some abortions are murder (because the child is a self owner).
  3. There is not a clear boundary between these two categories.
  4. In any disputed case, someone will have to determine whether or not an abortion is justified (the theory of acquired rights does not provide an objective basis to answer this a priori).
  5. Therefore abortion is justified, unless someone determines that it is not.

This vagueness is not how rights work. A valid theory of rights is supposed to be deducible by the agents on the ground who are making moral decisions. Yet advocates of the theory of acquired rights are quite content to acknowledge that they don't know when a child becomes a self owner. Here are some examples.

Tibor Machan openly admitted that he doesn't know when an individual becomes "a human being":

Finally, something more must be said about the grey area of borderline cases. The best solution to this problem is probably to provide a forum for debate. Given the seriousness of what is at stake, the courts—the judicial system—would seem to be the appropriate forum. When someone believes that a planned abortion could involve the killing of a human being—for example, at a very late stage of pregnancy—it might be appropriate to ask for a hearing on the matter.

-The Morality of Non-Interference by Tibor Machan

Judith Jarvis Thompson, author of the most influential philosophical defence of abortion, openly conceded that some abortions are unjustifiable killings but failed to identify what determined the validity of any particular case. She defended abortion but abdicated all responsibility for providing a clear moral rule by breezily saying that there is "room for much discussion":

there are some cases in which the unborn person has a right to the use of its mother’s body, and therefore some cases in which abortion is unjust killing. There is room for much discussion and argument as to precisely which, if any. At any rate the argument certainly does not establish that all abortion is unjust killing.

-A Defense of Abortion by Judith Jarvis Thomson

Stephan Kinsella simply assumes that a zygote cannot have rights but that an unborn child in late pregnancy does have rights, but gives no rule as to how to determine when rights acquisition occurs:

it seems obvious to me that a one-day old zygote has no rights yet, even though it is a potential human person, and biologically a “human life.”It also seems obvious to me that infants have rights, so that infanticide is murder. And that there is little difference between late-term abortion and infanticide

- Legal Foundations of a Free Society by Stephan Kinsella

To make a valid property rule, you have to specify which individual holds the property right and identify the points in time when he has these rights. If you don't specify these things, you've done it wrong and your property rule is invalid. This is the case with the theory of acquired rights. The property rule "children come to own themselves at some point before birth but it is unclear when" is a badly-formulated and invalid property rule.

Advocates of the theory of acquired rights sometimes resort to the defence that it is not their fault that the start of personhood or rights is unspecific, this is merely a reflection of the nature of things. They argue that fetuses become rights-bearing individuals at some point, but there is no way to provide a clear cutoff since it is a gradual process that cannot be made into a binary in a non-arbitrary way. Therefore it is impossible to be specific about when the child becomes a self owner.

This is not true. The ambiguity in this theory is not imposed by nature, it is chosen. At least for some advocates, the choice seems to be the result of motivated reasoning. Whatever the reason, such ambiguity is objectively unnecessary since there is a valid formulation of rights theory that is unambiguous. It is possible to identify an objective point at which a child becomes a self owner. The theory of inherent rights does this.

The Theory of Inherent Rights Conforms To The Specificity Principle

According to the theory of inherent rights, individuals have rights from the moment they come into existence. Unlike the theory of acquired rights, there is no vague and unspecified transition between a parent "owning" a child and a child becoming a self owner. Every individual is a self owner from the moment he comes into existence without ambiguity.

The theory of inherent rights provides an objective and definite temporal start to rights, and therefore is in compliance with Hoppe's specificity principle. The objective start is conception. As the philosopher Richard Werner pointed out, there is a non-arbitrary difference between two gametes prior to conception and a zygote after conception:

unlike the fetus immediately prior to birth and the baby immediately afterward, there is a significant and important difference between the ovum or sperm immediately before fertilization and the zygote immediately afterward. Given the proper environment the embryo, qua itself, is a growing developing organism. All things being equal, the zygote will grow into a person. On the other hand, the ovum or sperm qua itself is neither growing nor developing no matter what sort of environment one should find it, or put it into. A gamete will not, by itself, grow into anything other than what it already is— a gamete. In this sense it is inert and, thereby, nonhuman. A necessary condition of the ovum becoming human is that it begin to grow and develop into a person, that it be fertilized by a sperm cell. Otherwise, it remains inert never developing or growing into anything whatever and, as such, is no more a human being than is one of my red blood cells. Admittedly an acorn is not an oak, nor is an ovum or sperm cell human, but an acorn germinated in the soil is indeed an oak and so is the impregnated ovum a human.

Of the competing libertarian rights theories, only the theory of inherent rights is consistent with libertarian meta-ethical principles. Therefore rights are inherent, not acquired.
