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.

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.

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.
