The Nature of Moral Thinking is an introductory text to the questions of ethics, offering a solid philosophical and historical basis for understanding the central issues. Francis Snare discusses in detail the classical philosophical arguments of Plato and Butler in relation to relativism and subjectivism and treats Marx and Nietzsche in regard to the origins and explanation of morality.

Although Lawrence Kohlberg provided major ideas for psychological research in morality for decades, today some critics regard his work as outmoded, beyond repair, and too faulty for anybody to take seriously. These critics suggest that research would advance more profitably by taking a different approach. Postconventional Moral Thinking acknowledges particular philosophical and psychological problems with Kohlberg's theory and methodology, and proposes a reformulation called "Neo-Kohlbergian." Hundreds of researchers have reported a large body of findings after having employed Kohlberg's theory and methods to the Defining Issues Test (DIT), therefore attesting to the relevance of his ideas. This book provides a coherent theoretical overview for hundreds of studies that have used the DIT. The authors propose reformulations in the underlying psychological and philosophical theories. This book pulls together the analysis of criticisms of a Kohlbergian approach, a rationale for DIT research, and new theoretical ideas and new research.

A Harvard scientist illuminates the biological basis for human morality in this groundbreaking book. With the diversity of moral attitudes found across cultures around the globe, it is easy to assume that moral perspectives are socially developed—a matter of nurture rather than nature. But in Moral Minds, Marc Hauser presents compelling evidence to the contrary, and offers a revolutionary new theory: that humans have evolved a universal moral instinct. Hauser argues that certain biologically innate moral principles propel us toward 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.

Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking—staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms—if it is, as Joyce writes, "just something that helped our ancestors make more babies"—might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject. Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality.

An exploration of the character and evolution of disgust and the role this emotion plays in our social and moral lives. People can be disgusted by the concrete and by the abstract—by an object they find physically repellent or by an ideology or value system they find morally abhorrent. Different things will disgust different people, depending on individual sensibilities or cultural backgrounds. In Yuck!, Daniel Kelly investigates the character and evolution of disgust, with an emphasis on understanding the role this emotion has come to play in our social and moral lives. Disgust has recently been riding a swell of scholarly attention, especially from those in the cognitive sciences and those in the humanities in the midst of the "affective turn." Kelly proposes a cognitive model that can accommodate what we now know about disgust. He offers a new account of the evolution of disgust that builds on the model and argues that expressions of disgust are part of a sophisticated but largely automatic signaling system that humans use to transmit information about what to avoid in the local environment. He shows that many of the puzzling features of moral repugnance tinged with disgust are by-products of the imperfect fit between a cognitive system that evolved to protect against poisons and parasites and the social and moral issues on which it has been brought to bear. Kelly's account of this emotion provides a powerful argument against invoking disgust in the service of moral justification.
