All contentious moral issues--from gay marriage to abortion and affirmative action--raise difficult questions about the justification of moral beliefs. How can we be justified in holding on to our own moral beliefs while recognizing that other intelligent people feel quite differently and that many moral beliefs are distorted by self-interest and by corrupt cultures? Even when almost everyone agrees--e.g. that experimental surgery without consent is immoral--can we know that such beliefs are true? If so, how? These profound questions lead to fundamental issues about the nature of morality, language, metaphysics, justification, and knowledge. They also have tremendous practical importance in handling controversial moral questions in health care ethics, politics, law, and education. Sinnott-Armstrong here provides an extensive overview of these difficult subjects, looking at a wide variety of questions, including: Are any moral beliefs true? Are any justified? What is justified belief? The second half of the book explores various moral theories that have grappled with these issues, such as naturalism, normativism, intuitionism, and coherentism, all of which are attempts to answer moral skepticism. Sinnott-Armstrong argues that all these approaches fail to rule out moral nihilism--the view that nothing is really morally wrong or right, bad or good. Then he develops his own novel theory,--"moderate Pyrrhonian moral skepticism"--which concludes that some moral beliefs can be justified out of a modest contrast class but no moral beliefs can be justified out of an extreme contrast class. While explaining this original position and criticizing alternatives, Sinnott-Armstrong provides a wide-ranging survey of the epistemology of moral beliefs.

Philosophers have discussed virtue and character since Socrates, but many traditional views have been challenged by recent findings in psychology and neuroscience. This fifth volume of Moral Psychology grows out of this new wave of interdisciplinary work on virtue, vice, and character. It offers essays, commentaries, and replies by leading philosophers and scientists who explain and use empirical findings from psychology and neuroscience to illuminate virtue and character and related issues in moral philosophy. The contributors discuss such topics as eliminativist and situationist challenges to character; investigate the conceptual and empirical foundations of self-control, honesty, humility, and compassion; and consider whether the virtues contribute to well-being.

Philosophers and psychologists discuss new collaborative work in moral philosophy that draws on evolutionary psychology, cognitive science, and neuroscience. For much of the twentieth century, philosophy and science went their separate ways. In moral philosophy, fear of the so-called naturalistic fallacy kept moral philosophers from incorporating developments in biology and psychology. Since the 1990s, however, many philosophers have drawn on recent advances in cognitive psychology, brain science, and evolutionary psychology to inform their work. This collaborative trend is especially strong in moral philosophy, and these volumes bring together some of the most innovative work by both philosophers and psychologists in this emerging interdisciplinary field. The contributors to volume 1 discuss recent work on the evolution of moral beliefs, attitudes, and emotions. Each chapter includes an essay, comments on the essay by other scholars, and a reply by the author of the original essay. Topics include a version of naturalism that avoids supposed fallacies, distinct neurocomputational systems for deontic reasoning, the evolutionary psychology of moral sentiments regarding incest, the sexual selection of moral virtues, the evolution of symbolic thought, and arguments both for and against innate morality. Taken together, the chapters demonstrate the value for both philosophy and psychology of collaborative efforts to understand the many complex aspects of morality.

The contributors to volume 2 discuss recent empirical research that uses the diverse methods of cognitive science to investigate moral judgments, emotions, and actions. Each chapter includes an essay, comments on the essay by other scholars, and a reply by the author of the original essay. Topics include moral intuitions as a kind of fast and frugal heuristics, framing effects in moral judgments, an analogy between Chomsky's universal grammar and moral principles, the role of emotions in moral beliefs, moral disagreements, the semantics of moral language, and moral responsibility. Walter Sinnott-Armstrong is Professor of Philosophy and Hardy Professor of Legal Studies at Dartmouth College.

The neuroscience of morality is in its infancy, with the first brain imaging studies of moral development undertaken only in 2001. The contributors to volume 3 sample the best work in this very new field, discussing a variety of approaches, including functional imaging, lesion studies, abnormal psychology, and developmental neuroscience. Each chapter includes an essay, comments on the essay by other scholars, and a reply by the author of the original essay. Topics include the neural basis of moral emotions and moral judgments as well as comparisons of normal adult moral judgments with those made by children, adolescents, and people with psychopathy, brain damage, and autism.

In Moral Knowledge?: New Readings in Moral Epistemology, editors Walter Sinnott-Armstrong and Mark Timmons bring together eleven newly written essays by distinguished moral philosophers exploring the nature and possibility of moral knowledge. Each essay represents a major position within the exciting field of moral epistemology in which a proponent of the position presents and defends his or her view and locates it vis-a-vis competing views. The first chapter, written by Walter Sinnott-Armstrong, provides a framework for understanding the basic concepts and viewpoints in moral epistemology and presents a limited skeptical challenge to the justification of moral beliefs. The following essays represent various options in response to moral skepticism. Peter Railton and Simon Blackburn take different stances on moral truth and realism, Robert Audi defends a version of intuitionism, and Geoffrey Sayre-McCord adopts coherentism, while R.M. Hare combines elements of both foundationalism and coherentism. Richard Brandt discusses the relevance of empirical science to moral knowledge, Christopher Morris develops a contractarian account of moral justification, and David Copp bases moral knowledge on rational choices by societies. Margaret Urban Walker aruges for a feminist perspective on moral knowledge, and Mark Timmons expounds contextualism in moral epistemology. The lively and clear selections do not presuppose specialized knowledge of philosophy, and the philosophical vocabulary used throughout the anthology is uniform, in order to facilitate understanding by those not familiar with the field. The first chapter includes a sustained critical discussion of the major views represented in the following chapters, thereby furnishing beginning students with appropriate background to understand the selections. The volume is further enhanced by an index and an extensive bibliography, which is divided into sections corresponding to the chapters of the book. Moral Knowledge provides the most up-to-date work on moral knowledge and justification and serves as an excellent text for undergraduate and graduate courses.

Moral intuitions are strong, stable, immediate moral beliefs. Moral philosophers ask when they are justified. This question cannot be answered separately from a psychological question: How do moral intuitions arise? Their reliability depends upon their source. This chapter develops and argues for a new theory of how moral intuitions arise—that they arise through heuristic processes best understood as unconscious attribute substitutions. That is, when asked whether something has the attribute of moral wrongness, people unconsciously substitute a different question about a separate but related heuristic attribute (such as emotional impact). Evidence for this view is drawn from psychology and neuroscience, and competing views of moral heuristics are contrasted. It is argued that moral intuitions are not direct perceptions and, in many cases, are unreliable sources of evidence for moral claims.

A strong tradition in philosophy denies the possibility of moral dilemmas. Recently, several philosophers reversed this tradition. In this dissertation, I clarify some fundamental issues in this debate, argue for the possibility of moral dilemmas, and determine some implications of this possibility. ;In chapter I, I define moral dilemmas roughly as situations where an agent morally ought to adopt each of two alternatives but cannot adopt both. Moral dilemmas are resolvable if and only if one of the moral oughts overrides the other. ;In chapter II, I criticize several opponents of moral dilemmas, including utilitarians, Kant, Aquinas, and Ross. My main criticism is that no opponent of moral dilemmas can adequately justify moral residue . ;Chapters III and IV concern the two main arguments against the possibility of moral dilemmas. First, the argument for 'ought' implies 'can' runs as follows. If the agent cannot adopt both, then it is not the case that the agent ought to adopt both. But the agent ought to adopt both, since the agent ought to adopt each . Thus, the defining judgements of a moral dilemma seem to imply a contradiction. In response, I argue that the relation between 'ought' and 'can' is not a logical implication but a conversational implicature. ;Chapter IV concerns the argument from 'ought' implies 'permitted': If the agent ought to adopt one alternative, then the agent is permitted to adopt that alternative, which means that it is not the case that the agent ought not to adopt that alternative. But the agent ought not to adopt that alternative, since the agent ought to adopt the other alternative and cannot adopt both. I respond that 'ought' does not logically imply but conversationally implicates 'permitted'. ;In chapter V, I argue that, despite recent claims, both moral realism and anti-realism are compatible with the possibility of moral dilemmas. Thus, there are several reasons to accept and no reasons to deny the possibility of moral dilemmas
