The burgeoning science of ethics has produced a trend toward pessimism. Ordinary moral thought and action, we're told, are profoundly influenced by arbitrary factors and ultimately driven by unreasoned feelings. This book counters the current orthodoxy on its own terms by carefully engaging with the empirical literature. The resulting view, optimistic rationalism, shows the pervasive role played by reason our moral minds, and ultimately defuses sweeping debunking arguments in ethics. The science does suggest that moral knowledge and virtue don't come easily. However, despite the heavy influence of automatic and unconscious processes that have been shaped by evolutionary pressures, we needn't reject ordinary moral psychology as fundamentally flawed or in need of serious repair. Reason can be corrupted in ethics just as in other domains, but a special pessimism about morality in particular is unwarranted. Moral judgment and motivation are fundamentally rational enterprises not beholden to the passions.

“Surprising and remarkable…Toggling between big ideas, technical details, and his personal intellectual journey, Greene writes a thesis suitable to both airplane reading and PhD seminars.”—The Boston Globe Our brains were designed for tribal life, for getting along with a select group of others (Us) and for fighting off everyone else (Them). But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we can find our common ground. A grand synthesis of neuroscience, psychology, and philosophy, Moral Tribes reveals the underlying causes of modern conflict and lights the way forward. Greene compares the human brain to a dual-mode camera, with point-and-shoot automatic settings (“portrait,” “landscape”) as well as a manual mode. Our point-and-shoot settings are our emotions—efficient, automated programs honed by evolution, culture, and personal experience. The brain’s manual mode is its capacity for deliberate reasoning, which makes our thinking flexible. Point-and-shoot emotions make us social animals, turning Me into Us. But they also make us tribal animals, turning Us against Them. Our tribal emotions make us fight—sometimes with bombs, sometimes with words—often with life-and-death stakes. A major achievement from a rising star in a new scientific field, Moral Tribes will refashion your deepest beliefs about how moral thinking works and how it can work better.

Examines how practical reasoning can be put into the service of ethical and moral theory.

NEW YORK TIMES BESTSELLER • The acclaimed social psychologist challenges conventional thinking about morality, politics, and religion in a way that speaks to conservatives and liberals alike—a “landmark contribution to humanity’s understanding of itself” (The New York Times Book Review). Drawing on his twenty-five years of groundbreaking research on moral psychology, Jonathan Haidt shows how moral judgments arise not from reason but from gut feelings. He shows why liberals, conservatives, and libertarians have such different intuitions about right and wrong, and he shows why each side is actually right about many of its central concerns. In this subtle yet accessible book, Haidt gives you the key to understanding the miracle of human cooperation, as well as the curse of our eternal divisions and conflicts. If you’re ready to trade in anger for understanding, read The Righteous Mind.

In thirteen new essays and an introduction, Motivational Internalism collects a structured overview of current debates about motivational internalism and examines the nature of and evidence for forms of internalism, internalism's relevance for moral psychology and moral semantics, and ways of bridging the gap between internalist and externalist positions.

A new way of understanding the essence of moral obligation The Moral Nexus develops and defends a new interpretation of morality—namely, as a set of requirements that connect agents normatively to other persons in a nexus of moral relations. According to this relational interpretation, moral demands are directed to other individuals, who have claims that the agent comply with these demands. Interpersonal morality, so conceived, is the domain of what we owe to each other, insofar as we are each persons with equal moral standing. The book offers an interpretative argument for the relational approach. Specifically, it highlights neglected advantages of this way of understanding the moral domain; explores important theoretical and practical presuppositions of relational moral duties; and considers the normative implications of understanding morality in relational terms. The book features a novel defense of the relational approach to morality, which emphasizes the special significance that moral requirements have, both for agents who are deliberating about what to do and for those who stand to be affected by their actions. The book argues that relational moral requirements can be understood to link us to all individuals whose interests render them vulnerable to our agency, regardless of whether they stand in any prior relationship to us. It also offers fresh accounts of some of the moral phenomena that have seemed to resist treatment in relational terms, showing that the relational interpretation is a viable framework for understanding our specific moral obligations to other people.

An argument that moral functioning is immeasurably complex, mediated by biology but not determined by it. Throughout history, humanity has been seen as being in need of improvement, most pressingly in need of moral improvement. Today, in what has been called the beginnings of “the golden age of neuroscience,” laboratory findings claim to offer insights into how the brain “does” morality, even suggesting that it is possible to make people more moral by manipulating their biology. Can “moral bioenhancement”—using technological or pharmaceutical means to boost the morally desirable and remove the morally problematic—bring about a morally improved humanity? In The Myth of the Moral Brain, Harris Wiseman argues that moral functioning is immeasurably complex, mediated by biology but not determined by it. Morality cannot be engineered; there is no such thing as a “moral brain.” Wiseman takes a distinctively interdisciplinary approach, drawing on insights from philosophy, biology, theology, and clinical psychology. He considers philosophical rationales for moral enhancement, and the practical realities they come up against; recent empirical work, including studies of the cognitive and behavioral effects of oxytocin, serotonin, and dopamine; and traditional moral education, in particular the influence of religious thought, belief, and practice. Arguing that morality involves many interacting elements, Wiseman proposes an integrated bio-psycho-social approach to the consideration of moral enhancement. Such an approach would show that, by virtue of their sheer numbers, social and environmental factors are more important in shaping moral functioning than the neurobiological factors with which they are interwoven.

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