One of the most famous, and most derided, arguments against the morality of abortion is the argument from potential, which maintains that the fetus' potential to become a person and enjoy the valuable life common to persons, entails that its destruction is prima facie morally impermissible. In this paper, I will revisit and offer a defense of the argument from potential.

Drawing inspiration from the ethical pluralism of G. E. Moore's Principia Ethica, I contend that one empty world can be morally better than another. By ?empty? I mean that it is devoid of concrete entities (things that have a position in space or time). These worlds have no thickets or thimbles, no thinkers, no thoughts. Infinitely many of these worlds have laws of nature, abstract entities, and perhaps, space and time. These non-concrete differences are enough to make some of them (...) better than others. 1I thank Walter Sinnott-Armstrong, John Carroll, and Gideon Rosen for their comments and suggestions.

The most plausible pro-life argument claims that abortion is seriously wrong because it deprives the foetus of something valuable. This paper examines two recent versions of this argument. Don Marquis's version takes the valuable thing to be a 'future like ours', a future containing valuable experiences and activities. Jim Stone's version takes the valuable thing to be a future containing conscious goods, which it is the foetus's biological nature to make itself have. I give three grounds for rejecting these arguments. (...) First, they lead to unacceptable inequalities in the wrongness of killing. Second, they lead to counterintuitive results in a range of imaginary cases. Third, they ignore the role of psychological connectedness in determining the magnitude or seriousness of deprivation-based harms: because the foetus is only weakly psychologically connected to its own future, it cannot be seriously harmed by being deprived of that future.

A number of philosophers maintain that the destruction of an embryo in the first 2 weeks after fertilization is not morally problematic as it is metaphysically impossible for any human organism to then have existed. We contend that the typical adult human organism was once a zygote so there is no metaphysical shortcut to justify early abortion. We show that five arguments against human organisms ever having been zygotes fail. All of the arguments have to do with one variant or (...) another of the zygote or early embryo dividing. They do not provide any reason to believe that since some adult organisms are not identical to zygotes due to earlier divisions, none could have been. (shrink)

In her important and well-known discussion “On the Moral and Legal Status of Abortion,” Mary Anne Warren regrets that “it is not possible to produce a satisfactory defense of a woman’s right to obtain an abortion without showing that the fetus is not a human being, in the morally relevant sense.” Unlike some more cautious philosophers, Warren thinks that we can definitively demonstrate that the fetus is not a person. In this paper, Warren’s argument is critically examined with a focus (...) especially on the question of the foundation and the boundaries of the moral community. The fundamental thesis of the paper is that Warren’s approach is flawed for at least four reasons: (1) that being a person is not as obviously central to having full moral rights as Warren assumes, (2) that her exclusivism regarding moral status has dubious moral consequences independent of the abortion issue, (3) that it is not clear that a fetus is not a person, even on Warren’s own criteria, and (4) her criteria for personhood are themselves suspect.

Most opponents of abortion (OA) believe fetuses matter. Critics argue that OA act inconsistently with regards to fetal life, seeking to restrict access to induced abortion, but largely ignoring spontaneous abortion and the creation of surplus embryos by IVF. Nicholas Colgrove, Bruce Blackshaw, and Daniel Rodger call such arguments inconsistency arguments and contend they do not matter. They present three objections to these arguments — the other beliefs, other actions, and hypocrisy objection. Previously, I argued these objections fail and threaten (...) to undermine ethical inquiry. Colgrove et al. have recently replied, but here, I argue their reply fails as well and raises a new criticism of the other actions’ objection. This essay sets out to show, as well as any philosophical argument can, that inconsistency arguments are morally significant. (shrink)

Most opposition to induced abortion turns on the belief that human fetuses are persons from conception. On this view, the moral status of the fetus alone requires those in a position to provide aid—gestational mothers—to make tremendous sacrifices to benefit the fetus. Recently, critics have argued that this pro-life position requires more than opposition to induced abortion. Pro-life theorists are relatively silent on the issues of spontaneous abortion, surplus in vitro fertilisation human embryos, and the suffering and death of born (...) persons due to lack of access to food, shelter and medical care. Colgrove et al call such arguments inconsistency arguments, arguing they ‘do not matter’ and mischaracterise them as ad hominem attacks. Here, I argue these are better understood as moral dilemmas. While some critics argue pro-life inaction is evidence that they do not really believe human fetuses are persons, I contend this inaction is likely the result of resolvable confusion rather than moral negligence.

The contemporary philosophical literature on abortion primarily revolves around three seemingly intractable debates, concerning the (1) moral status of the fetus, (2) scope of women’s rights and (3) moral relevance of the killing/letting die distinction. The possibility of ectogenesis—technology that would allow a fetus to develop outside of a gestational mother’s womb—presents a unique opportunity for moral compromise. Here, I argue those opposed to abortion have aprima faciemoral obligation to pursue ectogenesis technology and provide ectogenesis for disconnected fetuses as part (...) of a moral compromise.

Patients in a minimally conscious state (MCS) fall into a different diagnostic category than patients in the more familiar vegetative states (VS). Not only are MCS patients conscious in some sense, they have a higher chance for recovery than VS patients. Because of these differences, we ostensibly have reason to provide MCS patients with care that goes beyond what we provide to patients with some VS patients. But how to justify this differential treatment? I argue we can’t justify it solely (...) by looking to MCS patients’ actual levels of consciousness. We must look also to the ways in which these patients are potentially conscious. Specifically, I argue that certain sensible and well-regarded policy recommendations cannot be justified by looking solely to patients’ actual levels of consciousness, but that they can be justified by looking to patients’ potential for consciousness. Insofar then as we have prima facie reason to follow the recommendations, we also have prima facie reason to view the potential for consciousness as morally salient. If that is true, however, several important implications follow: first, if the potential for consciousness is morally salient, this translates into actual and pressing obligations to patients with disorders of consciousness generally. Second, if the potential for consciousness is morally salient, this has implications that go beyond our obligations to patients with disorders of consciousness. Indeed, if the potential for consciousness is morally salient, this adds an important layer of complexity to the normative landscape, a layer we may not have sufficiently noticed before. (shrink)

Lockean accounts of personhood propose that an individual is a person just in case that individual is characterized by some advanced cognitive capacity. On these accounts, human beings with severe cognitive impairment are not persons. Some accept this result—I do not. In this paper, I therefore advance and defend an account of personhood that secures personhood for human beings who are cognitively impaired. On the account for which I argue, an individual is a person just in case that individual belongs (...) to a natural kind that is normally characterized by advanced cognitive capacities. Since “human being” is just such a natural kind, individual human beings can be persons even when they do not themselves have advanced cognitive capacities. I argue, furthermore, that we have good reason to accept this account of personhood over rival accounts since it is uniquely able to accommodate the intuitive concept of an impaired person. (shrink)

I discuss the propositional knowledge of an omniscient being, knowledge of facts that can be represented by that-clauses in sentences such as ‘John knows that the world is round.’ I shall focus upon questions about a supposedly omniscient being who propositionally knows the truth about all current states of affairs. I shall argue that there is no such being.

In this paper, a rights-based argument for the impermissibility of abortion, infanticide and neglect of some pre-natal organisms and infants/children is advanced. I argue, in opposition to most rights-ethicists, that the potentiality for autonomous agency gives individuals negative rights. I also examine the conjecture that potential autonomous agents have positive rights in virtue of their vulnerability. According to this suggestion, once an individual obtains actual autonomous agency, he or she has merely negative rights. Possible solutions to conflicts of rights between (...) parents and their offspring are investigated. Finally, I discuss a lexical order between positive and negative rights, which may solve conflicts between the rights of potential autonomous agents and actual autonomous agents. (shrink)
