In this classic text, Kant sets out to articulate and defend the Categorical Imperative - the fundamental principle that underlies moral reasoning - and to lay the foundation for a comprehensive account of justice and human virtues. This new edition and translation of Kant's work is designed especially for students. An extensive and comprehensive introduction explains the central concepts of Groundwork and looks at Kant's main lines of argument. Detailed notes aim to clarify Kant's thoughts and to correct some common (...) misunderstandings of his doctrines. (shrink)

In this engaging study, the authors put casuistry into its historical context, tracing the origin of moral reasoning in antiquity, its peak during the sixteenth and early seventeenth century, and its subsequent fall into disrepute from the mid-seventeenth century.

Researchers in moral psychology and social justice have agreed that morality is about matters of harm, rights, and justice. On this definition of morality, conservative opposition to social justice programs appears to be immoral, and has been explained as a product of various non-moral processes such as system justification or social dominance orientation. In this article we argue that, from an anthropological perspective, the moral domain is usually much broader, encompassing many more aspects of social life and valuing institutions as (...) much or more than individuals. We present theoretical and empirical reasons for believing that there are five psychological systems that provide the foundations for the world’s many moralities. The five foundations are psychological preparations for detecting and reacting emotionally to issues related to harm/care, fairness/reciprocity, ingroup/loyalty, authority/respect, and purity/sanctity. Political liberals have moral intuitions primarily based upon the first two foundations, and therefore misunderstand the moral motivations of political conservatives, who generally rely upon all five foundations.

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)

Marc Hauser puts forth the theory that humans have evolved a universal moral instinct, unconsciously propelling us to deliver judgments of right and wrong independent of gender, education, and religion. Combining his cutting-edge research with the latest findings in cognitive psychology, linguistics, neuroscience, evolutionary biology, economics, and anthropology, Hauser explores the startling implications of his provocative theory vis-à-vis contemporary bioethics, religion, the law, and our everyday lives.

Immanuel Kant's Groundwork of the Metaphysics of Morals ranks alongside Plato's Republic and Aristotle's Nicomachean Ethics as one of the most profound and influential works in moral philosophy ever written. In Kant's own words its aim is to search for and establish the supreme principle of morality, the categorical imperative. Kant argues that every human being is an end in himself or herself, never to be used as a means by others, and that moral obligation is an expression of the (...) human capacity for autonomy or self-government. This edition presents the acclaimed translation of the text by Mary Gregor, together with an introduction by Christine M. Korsgaard that examines and explains Kant's argument. (shrink)

Intended to convert religiously indifferent readers to Christianity, Pascal’s Pensees were published posthumously, to wide and ongoing acclaim. This selection of highlights focuses on their secular aspects and the author’s sensitive examination of human psychology as well as his popular epigrams. Written between 1656 and 1657 in support of the Jansenist movement, Provincial Letters captivated a large audience—including many of the cause’s opponents—with their satirical wit, righteous indignation, and effervescent style. This is the only dual-language edition available of these frequently (...) studied works. Introduction, notes. (shrink)

An Essay on the Nature and Conduct of the Passions and Affections, with Illustrations on the Moral Sense (1728), jointly with Francis Hutcheson’s earlier work Inquiry into the Original of Our Ideas of Beauty and Virtue (1725), presents one of the most original and wide-ranging moral philosophies of the eighteenth century. These two works, each comprising two semi-autonomous treatises, were widely translated and vastly influential throughout the eighteenth century in England, continental Europe, and America. -/- The two works had their (...) greatest impact in Scotland and influenced many well-known Scottish philosophers, particularly those writing after the last Jacobite upheaval, in 1745. This can be seen in the concern of the post-1745 generation with analyzing human nature as the foundation of moral theory, with the “moral sense” and moral epistemology more generally, with the impartial spectator and the calm passions, and with the independence of benevolence from self-interest. In addition to the influence of his writings, Hutcheson was also a famed teacher whose Glasgow students, notably Adam Smith, held sway over generations of Scottish moral philosophers. -/- Despite their impact on Scottish letters, the four treatises were in fact written in Dublin, and the philosophers to whom Hutcheson responded and with whom he debated were in the main not Scottish but English, Irish, French, Roman, and Greek. Consequently, part of Hutcheson’s legacy was a cosmopolitan outlook among enlightened Scots, who learned to turn their eyes far from home. (shrink)

An implicit association test (IAT) measures differential association of 2 target concepts with an attribute. The 2 concepts appear in a 2-choice task (e.g., flower vs. insect names), and the attribute in a 2nd task (e.g., pleasant vs. unpleasant words for an evaluation attribute). When instructions oblige highly associated categories (e.g., flower + pleasant) to share a response key, performance is faster than when less associated categories (e.g., insect + pleasant) share a key. This performance difference implicitly measures differential association (...) of the 2 concepts with the attribute. In 3 experiments, the IAT was sensitive to (a) near-universal evaluative differences (e.g., flower vs. insect), (b) expected individual differences in evaluative associations (Japanese + pleasant vs. Korean + pleasant for Japanese vs. Korean subjects), and (c) consciously disavowed evaluative differences (Black + pleasant vs. White + pleasant for self-described unprejudiced White subjects).

One of the reasons why most of us feel puzzled about the problem of abortion is that we want, and do not want, to allow to the unborn child the rights that belong to adults and children. When we think of a baby about to be born it seems absurd to think that the next few minutes or even hours could make so radical a difference to its status; yet as we go back in the life of the fetus we (...) are more and more reluctant to say that this is a human being and must be treated as such. No doubt this is the deepest source of our dilemma, but it is not the only one. For we are also confused about the general question of what we may and may not do where the interests of human beings conflict. We have strong intuitions about certain cases; saying, for instance, that it is all right to raise the level of education in our country, though statistics allow us to predict that a rise in the suicide rate will follow, while it is not all right to kill the feeble-minded to aid cancer research. It is not easy, however, to see the principles involved, and one way of throwing light on the abortion issue will be by setting up parallels involving adults or children once born. So we will be able to isolate the “equal rights” issue and should be able to make some advance... (shrink)

A long series of studies in social psychology have shown that the explanations people give for their own behaviors are fundamentally different from the explanations they give for the behaviors of others. Still, a great deal of uncertainty remains about precisely what sorts of differences one finds here. We offer a new approach to addressing the problem. Specifically, we distinguish between two levels of representation ─ the level of linguistic structure (which consists of the actual series of words used in (...) the explanation) and the level of conceptual structure (which consists of the concepts these words are used to express). We then formulate and test hypotheses both about self-other differences in conceptual structure and about self-other differences in the mapping from conceptual structure to linguistic structure.
