Distinctions have been proposed between systems of reasoning for centuries. This article distills properties shared by many of these distinctions and characterizes the resulting systems in light of recent findings and theoretical developments. One system is associative because its computations reflect similarity structure and relations of temporal contiguity. The other is "rule based" because it operates on symbolic structures that have logical content and variables and because its computations have the properties that are normally assigned to rules. The systems serve (...) complementary functions and can simultaneously generate different solutions to a reasoning problem. The rule-based system can suppress the associative system but not completely inhibit it. The article reviews evidence in favor of the distinction and its characterization. (shrink)

Climate change is an ethical issue, because it involves the distribution of a scarce resource – the capacity of the atmosphere to absorb our waste gases without producing consequences that no one wants. Various principles might be used to decide what distribution is just. This commentary argues that on any plausible principle, the industrialised nations should be doing much more than they are doing now, and much more than they are required to do by the Kyoto protocol, to reduce their (...) greenhouse gas emissions. The commentary also responds specifically to some issues raised by MacCracken, Toman and Gardiner, including feasibility, the discount rate, and grounds for pessimism. (shrink)

The series of 'trolley' examples issue a challenge to moral principles based on intentions, since it seems that these give the wrong answers in two important cases: 'Fat Man', where they seem to say that it is permissible to push someone in front of a trolley to save others, and 'Loop', where they seem to say that it is wrong to divert a trolley towards a single person whose body will stop it and save others. I reply, first, that there (...) is a parallel between the wrongful intention to mutilate in 'Transplant', where one person's vital organs are removed to save others' lives, and the intention to assault in Fat Man. Secondly, I defend Frances Kamm's view that in Loop one can divert the trolley towards the one without an intention to kill or assault, since good potential side-effects can be taken into account in deciding what to do, without their becoming intentions.

“The Trolley Problem” is the name Judith Jarvis Thomson has given to a difficult problem in moral philosophy and legal theory. The problem arises by considering a series of cases, all of which involve a choice of evils. Many, but not all of these cases, involve an out-of-control trolley about to run over a group of five people. In each case we are asked for our intuitive judgment as to whether it would be permissible to save the five people at (...) risk when doing so would require the death of, or the imposition of a high risk of death on, another human being.

Research on moral judgment has been dominated by rationalist models, in which moral judgment is thought to be caused by moral reasoning. The author gives 4 reasons for considering the hypothesis that moral reasoning does not cause moral judgment; rather, moral reasoning is usually a post hoc construction, generated after a judgment has been reached. The social intuitionist model is presented as an alternative to rationalist models. The model is a social model in that it deemphasizes the private reasoning done (...) by individuals and emphasizes instead the importance of social and cultural influences. The model is an intuitionist model in that it states that moral judgment is generally the result of quick, automatic evaluations (intuitions). The model is more consistent than rationalist models with recent findings in social, cultural, evolutionary, and biological psychology, as well as in anthropology and primatology. (shrink)

Traditional concern for the gradual, incremental effects of climate change remains; but now greater attention is being paid to the possibility of breaching major thresholds in the climate system with catastrophic consequences. It might be thought that the potential for abrupt climate change (a) undermines the usual (economic, psychological, and intergenerational) analyses of the climate change problem, and (b) in doing so helps us to act. Against this, I argue both that much of the psychological and intergenerational analyses remains in (...) place, and that abrupt climate change may make action more difficult, perhaps even setting off an intergenerational arms race.

Very few moral philosophers have written on climate change.1 This is puzzling, for several reasons. First, many politicians and policy makers claim that climate change is not only the most serious environmental problem currently facing the world, but also one of the most important international problems per se.2 Second, many of those working in other disciplines describe climate change as fundamentally an ethical issue.3.

The peculiar features of the climate change problem pose substantial obstacles to our ability to make the hard choices necessary to address it. Climate change involves the convergence of a set of global, intergenerational and theoretical problems. This convergence justifies calling it a 'perfect moral storm'. One consequence of this storm is that, even if the other difficult ethical questions surrounding climate change could be answered, we might still find it difficult to act. For the storm makes us extremely vulnerable (...) to moral corruption. (shrink)

Hume's place in history -- Moral psychology -- Strategic analysis -- Convention -- Political theory -- Justice as order -- Utilitarianism -- Value theory -- Retrospective.

David Hume (1711-76) is one of the greatest figures in the history of British philosophy. Of all of Hume's writings, the philosophically most profound is undoubtedly his first, A Treatise on Human Nature. Hume on Morality introduces and assesses: Hume's life and the background of the Treatise ; the ideas and text in the Treatise ; and Hume's continuing importance to philosophy. James Baillie provides us with a map to Books 2 and 3 of the Treatise, focusing on Hume's theory (...) of the passions and morality. This book sets out its principal ideas and arguments of the Treatise in a clear and readable way and is ideal for anyone coming to Hume's work for the first time. (shrink)

Climate change and justice are so closely associated that many people take it for granted that a global climate treaty should--indeed, must--directly address both issues together. But, in fact, this would be a serious mistake, one that, by dooming effective international limits on greenhouse gases, would actually make the world's poor and developing nations far worse off. This is the provocative and original argument of Climate Change Justice. Eric Posner and David Weisbach strongly favor both a climate change agreement and (...) efforts to improve economic justice. But they make a powerful case that the best--and possibly only--way to get an effective climate treaty is to exclude measures designed to redistribute wealth or address historical wrongs against underdeveloped countries. In clear language, Climate Change Justice proposes four basic principles for designing the only kind of climate treaty that will work--a forward-looking agreement that requires every country to make greenhouse--gas reductions but still makes every country better off in its own view. This kind of treaty has the best chance of actually controlling climate change and improving the welfare of people around the world. (shrink)

In our everyday lives, we confront a host of moral issues. Once we have deliberated and formed judgments about what is right or wrong, good or bad, these judgments tend to have a marked hold on us. Although in the end, we do not always behave as we think we ought, our moral judgments typically motivate us, at least to some degree, to act in accordance with them. When philosophers talk about moral motivation, this is the basic phenomenon they seek (...) to understand. Moral motivation is an instance of a more general phenomenon—what we might call normative motivation—for our other normative judgments also typically have some motivating force. When we make the normative judgment that something is good for us, or that we have a reason to act in a particular way, or that a specific course of action is the rational course, we also tend to be moved. Many philosophers have regarded the motivating force of normative judgments as the key feature that marks them as normative, thereby distinguishing them from the many other judgments we make. In contrast to our normative judgments, our mathematical and empirical judgments, for example, seem to have no intrinsic connection to motivation and action. The belief that an antibiotic will cure a specific infection may move an individual to take the antibiotic, if she also believes that she has the infection, and if she either desires to be cured or judges that she ought to treat the infection for her own good. All on its own, however, an empirical belief like this one appears to carry with it no particular motivational impact; a person can judge that an antibiotic will most effectively cure a specific infection without being moved one way or another.

Hume's position in ethics, which is based on his empiricist theory of the mind, is best known for asserting four theses: (1) Reason alone cannot be a motive to the will, but rather is the slave of the passions (see Section 3) (2) Moral distinctions are not derived from reason (see Section 4). (3) Moral distinctions are derived from the moral sentiments: feelings of approval (esteem, praise) and disapproval (blame) felt by spectators who contemplate a character trait or action (see (...) Section 7). (4) While some virtues and vices are natural (see Section 13), others, including justice, are artificial (see Section 9). There is heated debate about what Hume intends by each of these theses and how he argues for them. He articulates and defends them within the broader context of his metaethics and his ethic of virtue and vice. Hume's main ethical writings are Book 3 of his Treatise of Human Nature, Of Morals (which builds on Book 2, Of the Passions), his Enquiry concerning the Principles of Morals, and some of his Essays. In part the moral Enquiry simply recasts central ideas from the moral part of the Treatise in a more accessible style; but there are important differences. The ethical positions and arguments of the Treatise are set out below, noting where the moral Enquiry agrees; differences between the Enquiry and the Treatise are discussed afterwards. (shrink)
