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 three volumes bring together some of the most innovative work by both philosophers and psychologists in this emerging interdisciplinary field.

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.

Our personal and political worlds are rife with arguments and disagreements, some of them petty and vitriolic. The inability to compromise and understand the opposition is epidemic today, from countries refusing to negotiate, to politicians pandering to their base. Social media has produced a virulent world where extreme positions dominate. There is much demonization of the other side, very little progress is made, and the end result is further widening of positions. How did this happen, and what might be done to address it? Walter Sinnott-Armstrong says there is such a thing as a "good" argument: Reasonable arguments can create more mutual understanding and respect, and even if neither party is convinced by the other, compromise is still possible. Think Again shows the importance of good arguments and reveals common misunderstandings. Rather than a means to persuade other people or beat them in an intellectual competition, Sinnott-Armstrong sees arguments as an essential tool for constructive interaction with others. After showing how the failure of good arguments has led us to society's current woes, he shows readers what makes a good argument. In clear, lively, and practical prose, and with plentiful examples from politics, popular culture, and everyday life, Sinnott-Armstrong explains what defines an argument, identifies the components of good arguments as well as fallacies to avoid, and demonstrates what good arguments can accomplish. Armed with these tools, readers will be able to spot bad reasoning and bad arguments, and to advance their own views in a forceful yet logical way. These skills could even help repair our tattered civic culture.

Whether psychopathy is a mental disease or illness can affect whether psychiatrists should treat it and whether it could serve as the basis for an insanity defense in criminal trials. Our understanding of psychopathy has been greatly improved in recent years by new research in psychology and neuroscience. This illuminating research enables us to argue that psychopathy counts as a mental disease on any plausible account of mental disease. In particular, Szasz's and Pickard's eliminativist views and Sedgwick's social constructivist account of mental illness that might exclude psychopathy are not plausible, and there is no reason to exclude psychopathy under Boorse's and Scadding's biomedical accounts, Wakefield's harmful dysfunction account, and the DSM-IV-TR objective harm account of mental disease. The basic reason is that psychopathy involve neural dysfunction that increases risk of serious harm and loss to people with psychopathy.

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.
