: 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.

Crashes involving self-driving cars at least superficially resemble trolley dilemmas. This article discusses what lessons machine ethicists working on the ethics of self-driving cars can learn from trolleyology. The article proceeds by providing an account of the trolley problem as a paradox and by distinguishing two types of solutions to the trolley problem. According to an optimistic solution, our case intuitions about trolley dilemmas are responding to morally relevant differences. The pessimistic solution denies that this is the case. An optimistic (...) solution would yield first-order moral insights for the ethics of self-driving cars, but such a solution is difficult to come by. More plausible is the pessimistic solution, and it teaches us a methodological lesson. The lesson is that machine ethicists should discount case intuitions and instead rely on intuitions and judgments at a higher level of generality. (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.

A dominant trend in the philosophical literature on abortion has been concerned with the question of whether the fetus has moral status and how such a status might or might not conflict with women's liberties. However, a new and powerful trend against abortion requires philosophical examination. We refer to this trend as the paternalistic argument. In a nutshell, this argument holds that, insofar as motherhood is a constitutive end of women's well-being, abortion harms women; thus, abortion is wrong and should (...) be prohibited, restricted, or avoided when possible regardless of the moral status of the fetus. In this article we undertake three tasks. First, we analyze four variations of this reasoning: what we call the Kantian PA, the Aristotelian PA, the Catholic Church PA, and the Psychological PA. Second, we show how some public policies that regulate or prohibit abortion around the world are now in fact following paternalistic justifications and imposing distinctive paternalistic restrictions ; we refer to these policies as “the new abortion laws.” Finally, we argue that both the four paternalistic arguments presented and the new abortion laws are at times ill-intentioned, comprehensive in nature and thus unsuited for guiding public policy, empirically flawed, or else unjustified.

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

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)
