Among the hardest cases in the ethics of killing are those in which one innocent person poses a lethal threat to another. I argue in favour of the intuition that lethal self-defence is permissible in these cases, despite the difficulties that some philosophers (e.g., Otsuka and McMahan) have raised about it. Philosophers writing in this area—including those sympathetic to the intuition (e.g. Thomson and Kamm)—have downplayed or ignored an essential and authoritative role for intuition per se (as against discursive general (...) principles): one based in moral sensibility and imagination rather than discursive argument or conceptual analysis. I am concerned to call attention to and rehabilitate this role for intuition. (shrink)

This paper takes a novel approach to the active bioethical debate over whether advance medical directives have moral authority in dementia cases. Many have assumed that advance directives would lack moral authority if dementia truly produced a complete discontinuity in personal identity, such that the predementia individual is a separate individual from the postdementia individual. I argue that even if dementia were to undermine personal identity, the continuity of the body and the predementia individual’s rights over that body can support (...) the moral authority of advance directives. I propose that the predementia individual retains posthumous rights over her body that she acquired through historical embodiment in that body, and further argue that claims grounded in historical embodiment can sometimes override or exclude moral claims grounded in current embodiment. I close by considering how advance directives grounded in historical embodiment might be employed in practice and what they would and would not justify. (shrink)

In war a soldier behaving properly should take into account a universal requirement not to kill, to be applied strictly in dealing with civilians, but at the same time to support the exception of taking the life of enemy combatants as an act of selfdefense. This is the usual way to distinguish morally the proper treatment to soldiers and civilians. In this article the author criticizes it and outlines a different way to understand and justify the moral distinction mentioned.

Subjectivism about welfare is the view that something is basically good for you if and only if, and to the extent that, you have the right kind of favorable attitude toward it under the right conditions. I make a presumptive case for the falsity of subjectivism by arguing against nearly every extant version of the view. My arguments share a common theme: theories of welfare should be tested for what they imply about newborn infants. Even if a theory is intended (...) to apply only to adults, the fact that it is false of newborns may give us sufficient reason to reject it. (shrink)

According to theories of wrongful life (WL), the imposition upon a child of an existence of poor quality can constitute an act of harming, and a violation of the child’s rights. The idea that there can be WLs may seem intuitively compelling. But, as this paper argues, liberals who commit themselves to WL theories may have to compromise some of their other beliefs. For they will thereby become committed to the claim that some women are under a stringent moral duty (...) to have an abortion: a duty that could, without injustice, at least sometimes be enforced by the state. WL theories in other words imply that some women will lack a right to choose, under which both the decision to abort, and the decision to carry the fetus to term, are protected against interference. The paper exposes a dilemma, then, for liberals who are committed both to (a) the rights of future people not to be subjected to a harmful existence, and (b) the rights of women to refuse an abortion.

Anti-abortion violence (‘AAV’) is anathema to almost everyone, on all sides of the abortion debate. Yet, as this article aims to show, it is far more difficult than has previously been recognised to avoid the deeply unpalatable conclusion that it can sometimes be justified. Some of the most frequently-occupied positions on the morality of abortion will imply precisely that conclusion, I argue, unless conjoined with an especially stringent and unattractive form of pacifism. This is true not only of strict anti-abortion (...) views, but also, more surprisingly, of some of the most familiar and influential moderate defences of abortion rights. The latter conclusion raises the question, which further work will be required to fully resolve, of what our account of abortion ethics and prenatal moral status must be if it is to enable reconciliation of the common-sense rejections of both pacifism and AAV. I end with reasons to expect that the path to an account that satisfies this demand, without generating further significant intuitive problems, will be far from straightforward. (shrink)

Most people are skeptical of the claim that the expectation that a person would have a life that would be well worth living provides a reason to cause that person to exist. In this essay I argue that to cause such a person to exist would be to confer a benefit of a noncomparative kind and that there is a moral reason to bestow benefits of this kind. But this conclusion raises many problems, among which is that it must be (...) determined how the benefits conferred on people by causing them to exist weigh against comparable benefits conferred on existing people. In particular, might the reason to cause people to exist ever outweigh the reason to save the lives of existing people? (shrink)

It is natural for those with permissive attitudes toward abortion to suppose that, if they have examined all of the arguments they know against abortion and have concluded that they fail, their moral deliberations are at an end. Surprisingly, this is not the case, as I argue. This is because the mere risk that one of those arguments succeeds can generate a moral reason that counts against the act. If this is so, then liberals may be mistaken about the morality (...) of abortion. However, conservatives who claim that considerations of risk rule out abortion in general are mistaken as well. Instead, risk-based considerations generate an important but not necessarily decisive reason to avoid abortion. The more general issue that emerges is how to accommodate fallibilism about practical judgment in our decision-making. (shrink)

This paper deals with the conditions of liability to self-defense. When I use the term liability, I mean moral liability. This is different from desert. If I am liable to be killed in self-defense, it does not follow that I deserve to be killed. In short, desert entails liability but liability does not entail desert. My use of the term in this paper may be stated succinctly as follows: if killing a person will neither wrong him nor violate his rights, (...) he is morally liable to be killed. A person poses an unjust threat when he threatens harms that are neither justified nor excused. A person is culpable for an unjust threat if he intends the threat he poses, is a morally responsible agent, and there are no mitigating circumstances, such as duress, that excuse his actions. A person is at fault, but not culpable, for an unjust threat if he is a morally responsible agent, has acted unreflectively, recklessly, though not maliciously, in a way that poses risks to others. Though culpability entails fault, fault does not entail culpability; as I will explain later, a person does not have to be culpable in order to be at fault for an unjust threat. (shrink)

From the standpoint of a Christian philosopher, heeding the teaching and exhortations of Pope John Paul II and previous popes, I examine three directions in which the recent philosophical debate has developed. In the last seven or eight years there has been 1) a renewed focus on the biological issue of when a human individual comes to be, 2) new arguments for the proposition that personhood is a characteristic acquired after birth, and 3) refinements of the early argument of Judith (...) Thomson. Replying to these developments, I defend, on philosophical grounds, the pro-life position. I argue that a distinct, whole (though immature) human individual comes to be at conception, that he or she is a person, with full moral worth, from the moment he or she comes to be, and the mothers and fathers have a special responsibility to their children which entails (at least) that they ought not to choose to abort them. I conclude by briefly indicating, from the standpoint of Christian faith, why Christian philosophers should vigorously pursue this debate. (shrink)

Jon Shields's finding—that certain evangelical pro‐life activist groups are more interested in deliberative discussions about abortion than are pro‐choice activists—is wrong on methodological, normative, and philosophical grounds. He generalizes about pro‐life civility from a small, trained sample group, and ignores possibly important variables that would explain pro‐choicers' incivility. Further, politeness is not necessarily a requirement of democratic deliberation—which entails not forcing one's own beliefs on the public, as pro‐lifers manifestly are trying to do, despite their calm demeanor. Conversely, some pro‐choicers' (...) refusal to engage in debates is not a deliberative failure, as Shields suggests, as deliberation includes such things as campaigning and canvassing. Lastly, Shields, and the pro‐lifers he has observed, use the weakest of the pro‐choice arguments, instead of focusing on the best academic work in the field. (shrink)

The role of responsibility in our common-sense morality of self-defense is complex. According to common-sense morality, one can sometimes use substantial, even deadly, force against people who are only minimally responsible for posing a threat to us. The role of responsibility in self-defense is thus limited. However, responsibility is still sometimes relevant. It sometime affects how much force you can use against a threatener: less if they are less responsible and more if they are more responsible. Is there a well-motivated (...) theory that can explain both why the role of responsibility is limited and why it is sometimes relevant? It is hard to see what theory could unify these disparate elements of our common-sense morality, and if one cannot be found then we may simply have to revise some of our pre-theoretic beliefs. But it would be an important advantage of a theory if it could justify those beliefs. I will argue that there is a theory of this kind: surprisingly, the familiar rights theory of self-defense, defended by Judith Thomson, can do so if it is suitably supplemented. Along the way I will survey some alternative theories of self-defense and show why they are not up to the task. (shrink)
