The Emotions Morality And The Brain

In the last fifteen years, there has been significant interest in studying the brain structures involved in moral judgments using novel techniques from neuroscience such as functional magnetic resonance imaging (fMRI). Many people, including a number of philosophers, believe that results from neuroscience have the potential to settle seemingly intractable debates concerning the nature, practice, and reliability of moral judgments. This has led to a flurry of scientific and philosophical activities, resulting in the rapid growth of the new field of moral neuroscience. There is now a vast array of ongoing scientific research devoted towards understanding the neural correlates of moral judgments, accompanied by a large philosophical literature aimed at interpreting and examining the methodology and the results of this research. This is the first volume to take stock of fifteen years of research of this fast-growing field of moral neuroscience and to recommend future directions for research. It features the most up-to-date research in this area, and it presents a wide variety of perspectives on this topic.

Philosophers and psychologists discuss new collaborative work in moral philosophy that draws on evolutionary psychology, cognitive science, and neuroscience.

“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.

An overview of the latest interdisciplinary research on human morality, capturing moral sensibility as a sophisticated integration of cognitive, emotional, and motivational mechanisms. Over the past decade, an explosion of empirical research in a variety of fields has allowed us to understand human moral sensibility as a sophisticated integration of cognitive, emotional, and motivational mechanisms shaped through evolution, development, and culture. Evolutionary biologists have shown that moral cognition evolved to aid cooperation; developmental psychologists have demonstrated that the elements that underpin morality are in place much earlier than we thought; and social neuroscientists have begun to map brain circuits implicated in moral decision making. This volume offers an overview of current research on the moral brain, examining the topic from disciplinary perspectives that range from anthropology and neurophilosophy to justice and law. The contributors address the evolution of morality, considering precursors of human morality in other species as well as uniquely human adaptations. They examine motivations for morality, exploring the roles of passion, extreme sacrifice, and cooperation. They go on to consider the development of morality, from infancy to adolescence; findings on neurobiological mechanisms of moral cognition; psychopathic immorality; and the implications for justice and law of a more biological understanding of morality. These new findings may challenge our intuitions about society and justice, but they may also lead to more a humane and flexible legal system. Contributors Scott Atran, Abigail A.

Scientists no longer accept the existence of a distinct moral organ as phrenologists once did. A generation of young neurologists is using advanced technological medical equipment to unravel specific brain processes enabling moral cognition. In addition, evolutionary psychologists have formulated hypotheses about the origins and nature of our moral architecture. Little by little, the concept of a ‘moral brain’ is reinstated. As the crossover between disciplines focusing on moral cognition was rather limited up to now, this book aims at filling the gap. Which evolutionary biological hypotheses provide a useful framework for starting new neurological research? How can brain imaging be used to corroborate hypotheses concerning the evolutionary background of our species? In this reader, a broad range of prominent scientists and philosophers shed their expert view on the current accomplishments and future challenges in the field of moral cognition and assess how cooperation between neurology and evolutionary psychology can boost research into the field of the moral brain.

Since the 1990s, many philosophers have drawn on recent advances in cognitive psychology, brain science and evolutionary psychology to inform their work. These three volumes bring together some of the most innovative work by both philosophers and psychologists in this emerging, collaboratory field.

Jesse Prinz argues that recent work in philosophy, neuroscience, and anthropology supports two radical hypotheses about the nature of morality: moral values are based on emotional responses, and these emotional responses are inculcated by culture, not hard-wired through natural selection. In the first half of the book, Jesse Prinz defends the hypothesis that morality has an emotional foundation. Evidence from brain imaging, social psychology, and psychopathology suggest that, when we judge something to be right or wrong, we are merely expressing our emotions. Prinz argues that these emotions do not track objective features of reality; rather, the rightness and wrongness of an act consists in the fact that people are disposed to have certain emotions towards it. In the second half of the book, he turns to a defence of moral relativism. Moral facts depend on emotional responses, and emotional responses vary from culture to culture. Prinz surveys the anthropological record to establish moral variation, and he draws on cultural history to show how attitudes toward practices such as cannibalism and marriage change over time. He also criticizes evidence from animal behaviour and child development that has been taken to support the claim that moral attitudes are hard-wired by natural selection. Prinz concludes that there is no single true morality, but he also argues that some moral values are better than others; moral progress is possible. Throughout the book, Prinz relates his views to contemporary and historical work in philosophical ethics. His views echo themes in the writings of David Hume and Friedrich Nietzsche, but Prinz supports, extends, and revises these classic theories using the resources of cutting-edge cognitive science. The Emotional Construction of Morals will stimulate and challenge anyone who is curious about the nature and origin of moral values.

Despite the many attempts to disentangle the relationship between morality and emotion, as is clear from the myriad of approaches that try to understand the nature and importance of their connection, the extent of this synergy remains rather controversial. The multidisciplinary framework of the present volume was specifically designed to challenge self-containing disciplinary views, encouraging a more integrative analysis that covers various methodological angles and theoretical perspectives. Contributions include discussions on the interrelation between moral philosophy, emotion and identity, namely the clash between grand ethical theories and the practicality of human life; philosophical considerations on akrasia or the so called weakness of will, and the factors behind it; anthropological reflections on empathy and prosocial behavior; accounts from artificial intelligence and evolutionary game theory; and literary and artistic dissections of emotional responses to the representational power of fiction and the image. The inclusion of chapters from varied scientific backgrounds substantially enriches this debate and shows that several core questions, such as the ones related to identity and to the way we perceive the other and ourselves, are transversal. It is therefore valuable and pressing to further explore these common threads, and to encourage disciplinary dialogues across both traditional and emerging fields to help shed new light on the puzzling and fascinating ways in which morality and emotion are mutually imbricated.
