While many philosophers agree that evolutionary theory has important implications for the study of ethics, there has been no consensus on what these implications are. I argue that we can better understand these implications by examining two related yet distinct issues in evolutionary theory: the evolution of our moral beliefs and the evolution of cooperative behavior. While the prevailing evolutionary account of morality poses a threat to moral realism, a plausible model of how altruism evolved in human beings provides the grounding for a research program that focuses on achieving some of the more practical goals shared by ethicists. †To contact the author, please write to: Department of Political Science, Economics, and Philosophy, College of Staten Island/City University of New York, 2800 Victory Blvd., Staten Island, NY 10314; e‐mail: stephen.morris@csi.cuny.edu.

In the years leading up to the Second World War the ethologists Konrad Lorenz and Nikolaas Tinbergen, created the tradition of rigorous, Darwinian research on animal behavior that developed into modern behavioral ecology. At first glance, research on specifically human behavior seems to exhibit greater discontinuity that research on animal behavior in general. The 'human ethology' of the 1960s appears to have been replaced in the early 1970s by a new approach called ‘sociobiology’. Sociobiology in its turn appears to have been replaced by an approach calling itself Evolutionary Psychology. Closer examination, however, reveals a great deal of continuity between these schools. At present, whilst Evolutionary Psychology is the most visible form of evolutionary psychology, empirical and theoretical research on the evolution of mind and behavior is marked by a diversity of ideas and approaches and it is far from clear which direction(s) the field will take in future.

Classical evolutionary explanations of social behavior classify behaviors from their effects, not from their underlying mechanisms. Here lies a potential objection against the view that morality can be explained by such models, e.g. Trivers’reciprocal altruism. However, evolutionary theory reveals a growing interest in the evolution of psychological mechanisms and factors them in as selective forces. This opens up perspectives for evolutionary approaches to problems that have traditionally worried moral philosophers. Once the ability to mind-read is factored-in among the relevant variables in the evolution of moral abilities and counted among the selection pressures that have plausibly shaped our nature as moral agents, an evolutionary approach can contribute, so I will argue, to the solution of a long-standing debate in moral philosophy and psychology concerning the basic motivation for moral behavior.

Contemporary moral psychology has been enormously enriched by recent theoretical developments and empirical findings in evolutionary biology, cognitive psychology and neuroscience, and social psychology and psychopathology. Yet despite the fact that some theorists have developed specifically “social heuristic” (Gigerenzer, 2008) and “social intuitionist” (Haidt, 2007) theories of moral judgment and behavior, and despite regular appeals to the findings of experimental social psychology, contemporary moral psychology has largely neglected the social dimensions of moral judgment and behavior. I provide a brief sketch of these dimensions, and consider the implications for contemporary theory and research in moral psychology.

Human Nature After Darwin is an original investigation of the implications of Darwinism for our understanding of ourselves and our situation. It casts new light on current Darwinian controversies, and in doing so provides an introduction to philosophical reasoning and a range of philosophical problems. Janet Radcliffe Richards claims that many current battles about Darwinism, in particular about evolutionary psychology and religion, are based on mistaken assumptions about the implications of the rival views. Her analysis of these implications provides a much-needed guide to the fundamentals of Darwinism and the so-called Darwin-wars, as well as providing a set of philosophical techniques relevant to wide areas of moral and political debate. It also raises philosophical problems of knowledge and certainly, free will and responsibility, altruism, the status of ethics, and the relevance of Darwinism to questions of ethics, politics and religion. The lucid presentation makes the book an ideal introduction to both philosophy and Darwinism, as well as a substantive contribution to topics of intense current controversy. It will be of interest to students of philosophy, science and the social sciences, and critical thinking.

The defining insight of evolutionary psychology consists of bringing considerations drawn from evolutionary biology to bear on the study of human psychology. So characterized, evolutionary psychology encompasses a large range of views about the nature and evolution of human psychology as well as diverging opinions about the proper method for studying them.¹ In this article, I propose to clarify and evaluate various aspects of evolutionary psychologists’ methodology, with a special focus on their heuristics of discovery—i.e., their methods for developing plausible hypotheses—and their strategies of confirmation—i.e., their methods for providing empirical support for these hypotheses.² I will also evaluate several well-known objections raised against evolutionary psychology. Note that because views about psychology and evolution differ among evolutionary psychologists, I do not pretend to cover every method used in evolutionary psychology.³.
