This paper takes on several distinct but related tasks. First, I present and discuss what I will call the “Ignorance Thesis,” which states that whenever an agent acts from ignorance, whether factual or moral, she is culpable for the act only if she is culpable for the ignorance from which she acts. Second, I offer a counterexample to the Ignorance Thesis, an example that applies most directly to the part I call the “Moral Ignorance Thesis.” Third, I argue for a (...) principle—Don’t Know, Don’t Kill—that supports the view that the purported counterexample actually is a counterexample. Finally, I suggest that my arguments in this direction can supply a novel sort of argument against many instances of killing and eating certain sorts of animals. (shrink)

: To what extent do moral judgments depend on conscious reasoning from explicitly understood principles? We address this question by investigating one particular moral principle, the principle of the double effect. Using web-based technology, we collected a large data set on individuals’ responses to a series of moral dilemmas, asking when harm to innocent others is permissible. Each moral dilemma presented a choice between action and inaction, both resulting in lives saved and lives lost. Results showed that: patterns of moral (...) judgments were consistent with the principle of double effect and showed little variation across differences in gender, age, educational level, ethnicity, religion or national affiliation and a majority of subjects failed to provide justifications that could account for their judgments. These results indicate that the principle of the double effect may be operative in our moral judgments but not open to conscious introspection. We discuss these results in light of current psychological theories of moral cognition, emphasizing the need to consider the unconscious appraisal system that mentally represents the causal and intentional properties of human action.

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.

Experimental ethicists investigate traditional ethical questions with non-traditional means, namely with the methods of the empirical sciences. Studies in this area have made heavy use of philosophical thought experiments such as the well-known trolley cases. Yet, the specific function of these thought experiments within experimental ethics has received little consideration. In this paper we attempt to fill this gap. We begin by describing the function of ethical thought experiments, and show that these thought experiments should not only be classified according (...) to their function but also according to their scope. On this basis we highlight several ways in which the use of thought experiments in experimental ethics can be philosophically relevant. We conclude by arguing that experimental philosophy currently only focuses on a small subcategory of ethical thought experiments and suggest a broadening of its research agenda. (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)

Advances in reproductive genetic engineering have the potential to transform human lives. Not only do they promise to allow us to select children free of diseases, they can also enable us to select children with desirable traits. In this paper, I consider two clusters of arguments for the moral permissibility of reproductive genetic engineering, what I call the Perfectionist View and the Libertarian View; and two clusters of arguments against reproductive genetic engineering, what I call the Human Nature View and (...) the Motivation View. I argue that an adequate theory of the ethics of reproductive genetic engineering should take into account insights gained from these views. (shrink)

This thesis takes up a rights-based perspective to discuss a number of issues related to the problem of permissible harm. It appeals to a person’s capacity to shape her life in accordance with her own ideas of the good to explain why her death can be bad for her, and why each of us should have primary say over what may be done to her. The thesis begins with an investigation of the badness of death for the person who dies. (...) If death is bad for us, this helps explain the wrongness of killing. The thesis defends the deprivation account—i.e. the idea that death is bad for us when and because it deprives us of good life—against two Epicurean challenges. It adds that death is also bad when and because it thwarts our agency. Next, the thesis deals with the logic of our moral rights to non-interference. It proposes a conception of rights according to which the stringency of our rights derives from and is justified by the rational aspect of our human nature. It argues that this conception of moral rights solves the paradox of deontology. While our rights to non-interference are stringent, they are not absolute. The thesis considers two possible exceptions to the general rule that it is impermissible to harm an innocent person against her consent. First, using an actual case from WWII, it investigates the circumstances under which a government may expose some parts of its population to an increased risk of harm in order to decrease the risk to others. Second, it considers the permissibility of self-defence against an innocent threat. It argues that the potential victim of an innocent threat has a justice-based reason to treat her own interests as on a par with those of the threat. (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)

Policy-makers have attempted to frame the ethical requirements that are relevant to the creation of human beings via reproductive technologies. Various reports and laws enacted in New Zealand, Canada, Australia, and Britain have introduced tests for how we should weigh child welfare when using these technologies. A number of bioethicists have argued that child welfare should be interpreted as a “best interests” test. Others have argued that there are ethical reasons why we should abandon this kind of test. I will (...) argue that at least some of the relevant policy can be interpreted as requiring those wishing to exercise their procreative liberty to have a reasonable plan to care and nurture any resulting child, thereby respecting the internal preconditions of that liberty. This interpretation of child welfare requirements answers some of the ethical worries about a child welfare test. (shrink)

Agent-relative restrictions prohibit minimizing violations: that is, they require us not to minimize the total number of their violations by violating them ourselves. Frances Kamm has explained this prohibition in terms of the moral worth of persons, which, in turn, she explains in terms of persons’ high moral status as inviolable beings. I press the following criticism of this account: even if minimizing violations are permissible, we need not have a lower moral status provided other determinants thereof boost it. Thus, (...) Kamm’s account is incomplete at best. And when, to address this incompleteness, it is insisted that our moral worth derives from specific moral statuses, the inviolability account comes to seem deficient because it begs the question against those who are not initially persuaded that minimizing violations are impermissible.

A growing body of scholarship argues that by disentangling gestation from the body, artificial wombs will alter the relationship between men, women, and fetuses such that reproduction is effectively ‘degendered’. Scholars have claimed that this purported ‘degendering’ of gestation will subsequently create greater equity between men and women. I argue that, contrary to the assumptions made in this literature, it is law, not biology, that acts as a primary barrier to the ‘degendering’ of gestation. With reference to contemporary case law (...) involving disputes over frozen embryos, I demonstrate that though reproductive technologies have already made it possible for gendered progenitors to have an ‘equal’ say in gestation, law mires the possibilities of these technologies in traditional stories of gendered parenthood. Looking to the way binary assumptions about gender limit the self-determination of trans men and nonbinary and genderqueer people who are gestational parents, I argue the ‘degendering’ of gestation will come not with artificial wombs but with the end of limited legal paradigms for gendered gestational parenthood.

It is sometimes proposed that killing or harming abortion providers is the only logically consistent position available to opponents of abortion. Since lethal violence against morally responsible attackers is normally viewed as justified in order to defend innocent parties, pro-lifers should also think so in the case of the abortion doctor and so they should act to defend the unborn. In our paper, we defend the mainstream pro-life view against killing abortion doctors. We argue that the pro-life view can, in (...) various ways, reject the assumption that defensive violence to save innocent individuals is always permissible. Now even if that assumption is accepted, we contend that defensive violence against abortion doctors still is not justified. Drawing on Frances Kamm’s work, we contend that there are structural similarities between abortion and letting someone die who needs your help to stay alive; and we argue that it is impermissible to kill those who kill in order to avoid giving life-saving aid.

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 essay explores whether dependent relationships might justify extending direct moral consideration to nonhuman animals. After setting out a formal conception of moral standing as relational, scalar, and unilateral, I consider whether and how an appeal to dependencies might be the basis for an animal’s moral standing. If dependencies generate reasons for extending direct moral consideration, such reasons will admit of significant variations in scope and stringency.

Re-Reading: Judith Jarvis Thompson, 'A Defense of Abortion'.

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 philosophers Peter Singer and Jeff McMahan hold variations of the view that infant interests in continued life are suspect because infants lack the cognitive complexity to anticipate the future. Since infants cannot see themselves as having a future, Singer argues that the future cannot have value for them, and McMahan argues that the future can only have minimal value for an infant. This paper critically analyzes these arguments and defends the view that infants can have interests in continuing to (...) live. Even though infants themselves lack a strong psychological connection to the future, others who are involved in an infant’s life can anticipate, on an infant’s behalf, the kind of future that awaits the infant, and on the basis of this insight judge that continuing to live would be in the infant’s interests. After defending this position, I argue that this position on the interests of infants in continued life does not commit one to opposing abortion, and it does not commit one to the view that our ethical obligations to protect the lives of sentient animals are the same as our ethical obligations to protect infant lives.
