A controversial inquiry into the origins of human values.

While most people throughout history have believed that we are both physical and spiritual beings, the rise of science has called into question the existence of the soul. Many now argue that neurophysiology demonstrates the radical dependence, indeed, identity, between mind and brain. Advances in genetics and in mapping human DNA, some say, show there is no need for the hypothesis of body-soul dualism. Even many Christian intellectuals have come to view the soul as a false Greek concept that is outdated and unbiblical. Concurrent with the demise of dualism has been the rise of advanced medical technologies that have brought to the fore difficult issues at both edges of life. Central to questions about abortion, fetal research, reproductive techologies, cloning and euthanasia is our understanding of the nature of human personhood, the reality of life after death and the value of ethical or religious knowledge as compared to scientific knowledge. In this careful treatment, J. P. Moreland and Scott B. Rae argue that the rise of these problems alongside the demise of Christian dualism is no coincidence. They therefore employ a theological realism to meet these pressing issues, and to present a reasonable and biblical depiction of human nature as it impinges upon critical ethical concerns. This vigorous philosophical and ethical defense of human nature as body and soul, regardless of whether one agrees or disagrees, will be for all a touchstone for debate and discussion for years to come.

A distinguished international team of philosophers offer responses to the work of Bernard Williams, followed by the author's reply.

“Provocative and richly textured. . . .Schwartz’s analyses of the inadequacies of contemporary scientific views of human nature are compelling, but the consequences are even more worthy of note.” —Los Angeles Times Out of the investigations and speculations of contemporary science, a challenging view of human behavior and society has emerged and gained strength. It is a view that equates “human nature” utterly and unalterably with the pursuit of self-interest. Influenced by this view, people increasingly appeal to natural imperatives, instead of moral ones, to explain and justify their actions and those of others.

The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

“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.

A concise and accessible introduction to natural law ethics, this book introduces readers to the mainstream tradition of Western moral philosophy. Building on philosophers from Plato through Aquinas to John Finnis, Alfonso Gómez-Lobo links morality to the protection of basic human goods--life, family, friendship, work and play, the experience of beauty, knowledge, and integrity--elements essential to a flourishing, happy human life. Gómez-Lobo begins with a discussion of Plato's Crito as an introduction to the practice of moral philosophy, showing that it requires that its participants treat each other as equals and offer rational arguments to persuade each other. He then puts forth a general principle for practical rationality: one should pursue what is good and avoid what is bad. The human goods form the basis for moral norms that provide a standard by which actions can be evaluated: do they support or harm the human goods? He argues that moral norms should be understood as a system of rules whose rationale is the protection and enhancement of human goods. A moral norm that does not enjoin the preservation or enhancement of a specific good is unjustifiable. Shifting to a case study approach, Gómez-Lobo applies these principles to a discussion of abortion and euthanasia. The book ends with a brief treatment of rival positions, including utilitarianism and libertarianism, and of conscience as our ultimate moral guide. Written as an introductory text for students of ethics and natural law, Morality and the Human Goods makes arguments consistent with Catholic teaching but is not based on theological considerations. The work falls squarely within the field of philosophical ethics and will be of interest to readers of any background.

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”.

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.
