“A welcome renewal and defense of John Dewey's ethical naturalism, which Johnson claims is the only morality ‘fit for actual human beings.’” —Notre Dame Philosophical Reviews What is the difference between right and wrong? This is no easy question to answer, yet we constantly try to make it so, frequently appealing to absolutes, whether drawn from God, universal reason, or societal authority. Combining cognitive science with a pragmatist philosophical framework, Mark Johnson argues that appealing solely to absolute principles is not only scientifically unsound but even morally suspect. He shows that the standards for the kinds of people we should be and how we should treat one another are frequently subject to change. Taking context into consideration, he offers a nuanced, naturalistic view of ethics that sees us creatively adapt our standards according to given needs, emerging problems, and social interactions. Ethical naturalism is not just a revamped form of relativism. Indeed, Johnson attempts to overcome the absolutist-versus-relativist impasse that has been one of the most intractable problems in the history of philosophy. Much of our moral thought, he shows, is automatic and intuitive, gut feelings that we attempt to justify with rational analysis and argument. However, good moral deliberation is not limited to intuitive judgments supported after the fact by reasoning. Johnson points out a crucial third element: we imagine how our decisions will play out, how we or the world would change with each action we might take. Plumbing this imaginative dimension of moral reasoning, he provides a psychologically sophisticated view of moral problem solving, one perfectly suited for the embodied, culturally embedded, and ever-developing human creatures that we are.

Using path-breaking discoveries of cognitive science, Mark Johnson argues that humans are fundamentally imaginative moral animals, challenging the view that morality is simply a system of universal laws dictated by reason. According to the Western moral tradition, we make ethical decisions by applying universal laws to concrete situations. But Johnson shows how research in cognitive science undermines this view and reveals that imagination has an essential role in ethical deliberation. Expanding his innovative studies of human reason in Metaphors We Live By and The Body in the Mind, Johnson provides the tools for more practical, realistic, and constructive moral reflection.

Many debates about the moral status of things—for example, debates about the natural rights of human fetuses or nonhuman animals—eventually migrate towards a discussion of the capacities of the things in question—for example, their capacities to feel pain, think, or love. Yet the move towards capacities is often controversial: if a human’s capacities are the basis of its moral status, how could a human having lesser capacities than you and I have the same "serious" moral status as you and I? This book answers this question by arguing that if something is human, it has a set of typical human capacities; that if something has a set of typical human capacities, it has serious moral status; and thus all human beings have the same sort of serious moral status as you and I. Beginning from what our common intuitions tell us about situations involving "temporary incapacitation"—where a human organism has, then loses, then regains a certain capacity—this book argues for substantive conclusions regarding human fetuses and embryos, humans in a permanent vegetative state, humans suffering from brain diseases, and humans born with genetic disorders. Since these conclusions must have some impact on our ongoing moral and political debates about the proper treatment of such humans, this book will be useful to professionals and students in philosophy, bioethics, law, medicine, and public policy.

Sam Harris dismantles the most common justification for religious faith--that a moral system cannot be based on science.

Michael Tomasello offers the most detailed account to date of the evolution of human moral psychology. Based on experimental data comparing great apes and human children, he reconstructs two key evolutionary steps whereby early humans gradually became an ultra-cooperative and, eventually, a moral species capable of acting as a plural agent “we”.

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.
