This fascinating and timely volume explores current thinking on vital topics in moral psychology, spanning the diverse disciplines that contribute to the field. Academics from cognitive science, evolutionary biology, anthropology, philosophy, and political science address ongoing and emerging questions aimed at understanding the thought processes and behaviors that underlie our moral codesβand our transgressions. Cross-cutting themes speak to individual, interpersonal, and collective morality in such areas as the development of ethical behavior, responses to violations of rules, moral judgments in the larger discourse, and universal versus specific norms. This wide-angle perspective also highlights the implications of moral psychology research for policy and justice, with cogent viewpoints from: Β· Philosophy: empiricism and normative questions, moral relativism. Β· Evolutionary biology: theories of how altruism and moral behavior evolved. Β· Anthropology: common moral values seen in ethnographies from different countries. Β· Cognitive and neural sciences: computational models of moral systems and decision-making. Β· Political science: politics, governance, and moral values in the public sphere. Β· Advice on moral psychology researchβand thoughts about its futureβfrom prominent scholars. With the goal of providing a truly multidisciplinary forum for moral psychology, this volume is sure to spark conversations across disciplines and advance the field as a whole. Sampling the breadth and depth of an equally expansive and transformative field, Moral Psychology: A Multidisciplinary Guide will find an engaged audience among psychologists, philosophers, evolutionary biologists, anthropologists, political scientists, neuroscientists, lawyers, and policymakers, as well as a more general audience interested in better understanding the complexity of moral psychology research.
