Many academics and world leaders have declared that there is a moral imperative to address climate change. But such claims often fall on deaf ears because the nature of the threat posed by global warming lacks many of the features of a paradigmatic moral transgression [Jamieson, Dale. 2007. The moral and political challenges of climate change. Working Paper, New York University, New York]. This paper explores these psychological obstacles to moral engagement about climate change. I argue that the temporal and (...) psychosocial distance of the threat of global warming undermines the kind of affective response that motivates moral concern. I conclude by suggesting that images focusing more on the personal and short-term consequences of global warming will generate stronger moral reactions. (shrink)

In this article I attempt to show conclusively that the apparent intrinsic difference between causing collateral damage and directly attacking innocents is an illusion. I show how eleven morally irrelevant alterations can transform an apparently permissible case of harming as a side-effect into an apparently impermissible case of harming as a means. The alterations are as obviously irrelevant as the victims’ skin colour, and consistently treating them as relevant would have unacceptable implications for choices between more and less harmful ways (...) of securing greater goods. This shows not only how the principles philosophers have proposed for distinguishing between these cases cannot withstand scrutiny, but how we can be sure that there are no relevant differences yet to be discovered. I conclude by considering reasons to think that there are deontological constraints against harming, but that they apply just as forcefully against collateral harms as they do against intended harms.

Various theories of moral cognition posit that moral intuitions can be understood as the output of a computational process performed over structured mental representations of human action. We propose that action plan diagrams—“act trees”—can be a useful tool for theorists to succinctly and clearly present their hypotheses about the information contained in these representations. We then develop a methodology for using a series of linguistic probes to test the theories embodied in the act trees. In Study 1, we validate the (...) method by testing a specific hypothesis (diagrammed by act trees) about how subjects are representing two classic moral dilemmas and finding that the data support the hypothesis. In Studies 2–4, we explore possible explanations for discrete and surprising findings that our hypothesis did not predict. In Study 5, we apply the method to a less well‐studied case and show how new experiments generated by our method can be used to settle debates about how actions are mentally represented. In Study 6, we argue that our method captures the mental representation of human action better than an alternative approach. A brief conclusion suggests that act trees can be profitably used in various fields interested in complex representations of human action, including law, philosophy, psychology, linguistics, neuroscience, computer science, robotics, and artificial intelligence.

An externalist view of intention is developed on broadly Wittgensteinian grounds, and applied to show that the classic Thomist doctrine of double effect, though it has good uses in casuistry, has also been overused because of the internalism about intention that has generally been presupposed by its users. We need a good criterion of what counts as the content of our intentional actions; I argue, again on Wittgensteinian grounds, that the best criterion comes not from foresight, nor from foresight plus (...) some degree of probability, nor from any metaphysics of “closeness”, but simply from our ordinary shared understanding of what counts as doing a given action, and what does not.

The trolley problem, first described by Foot (1967) and Thomson (The Monist, 59, 204–217, 1976), is one of the most famous and influential thought experiments in deontological ethics. The general story is that a runaway trolley is threatening the lives of five people. Doing nothing will result in the death of those persons, but acting in order to save those persons would unavoidably result in the death of another, sixth person. It appears that, depending on the situation, we have different (...) moral judgments about the permissibility of action. We will review and systematize all the proposals in the literature of the past 35 years that have attempted to grasp our moral intuitions in a simple deontological principle. In particular, seventeen proposals will be classified: six algorithmic, seven psychological, and four other invalid accounts. This review and classification sheds light on some subtle differences and clarify a few issues. (shrink)

This paper deals with the core version of the Trolley Problem. In one case many people favor an act which will bring about the death of one person but save five other persons. In another case most people would refuse to “sacrifice” one person in order to save five other lives. Since the two cases seem similar in all relevant respects, we have to explain and justify the diverging verdicts. Since I don’t find current proposals of a solution convincing, I (...) propose an alternative one according to which —but not —violates two forms of equality. I also test the underlying egalitarian principle against other cases. I argue that it offers a good explanation and also a normative justification of our intuitive verdicts about the cases. (shrink)

The Doctrine of Double Effect [DDE] states roughly that it is harder to justify causing or allowing harm as a means to an end than it is to justify conduct that results in harm as a side effect. This chapter argues that a theory of deontological constraints on harming needs something like the DDE in order to avoid the charge that it reflects a narcissistic obsession with the cleanliness of our own hands. Unfortunately, the DDE is often interpreted as maintaining (...) that we must avoid acting with certain intentions, which, this chapter contends, embodies an equally narcissistic obsession with the purity of our own hearts. The chapter argues that the DDE is better interpreted as a denial of the Machiavellian idea that beneficial ends justify harmful means. On this view, the objective fact that our conduct will secure benefits for some individuals at the expense of other individuals weakens the extent to which those benefits count as reasons to engage in that conduct. The chapter argues that this version of the DDE provides a plausible, non-narcissistic foundation for deontological constraints. (shrink)
