These essays focus on questions that arise when morality is considered from the perspective of rational choice and evolution. It links questions like ""is it rational to be moral?"" to the evolution of co-operation, and uses models from game theory, evolutionary biology and cognitive science.

It is certainly the case that morality governs the interactions that take place between individuals. But what if morality exists because of these interactions? This book, first published in 2007, argues for the claim that much of the behaviour we view as 'moral' exists because acting in that way benefits each of us to the greatest extent possible, given the socially structured nature of society. Drawing upon aspects of evolutionary game theory, the theory of bounded rationality, and computational models of social networks, it shows both how moral behaviour can emerge in socially structured environments, and how it can persist even when it is not typically viewed as 'rational' from a traditional economic perspective. This book also provides a theory of how moral principles and the moral sentiments play an indispensable role in effective choice, acting as 'fast and frugal heuristics' in social decision contexts.

Why do people behave in moral ways in some circumstances, but not in others? In order to account fully for morality, Dennis Krebs departs from traditional approaches to morality that suggest that children acquire morals through socialization, cultural indoctrination, and moral reasoning. He suggests that such approaches can be subsumed, refined, and revised gainfully within an evolutionary framework. Relying on evolutionary theory, Krebs offers an account of how notions of morality originated in the human species. He updates Darwin's early ideas about how dispositions to obey authority, to control antisocial urges, and to behave in altruistic and cooperative ways originated and evolved, then goes on to update Darwin's account of how humans acquired a moral sense.Krebs explains why the theory of evolution does not dictate that all animals are selfish and immoral by nature. On the contrary, he argues that moral behaviors and moral judgments evolved to serve certain functions. Krebs examines theory and research on the evolution of primitive forms of prosocial conduct displayed by humans and other animals, then discusses the evolution of uniquely human prosocial behaviors. He describes how a sense of morality originated during the course of human evolution through strategic social interactions among members of small groups, and how it was expanded and refined in modern societies, explaining how this sense gives rise to culturally universal and culturally relative moral norms. Krebs argues that although humans' unique cognitive abilities endow them with the capacity to engage in sophisticated forms of moral reasoning, people rarely live up their potential in their everyday lives. Four conceptions of what it means to be a moral person are identified, with the conclusion that people are naturally inclined to meet the standards of each conception under certain conditions. The key to making the world a more moral place lies in creating environments in which good guys finish first and cheaters fail to prosper.

Winner of the William James Book Award Winner of the inaugural Expanded Reason Award A wide-ranging exploration of the role of childhood experiences in adult morality. Moral development has traditionally been considered a matter of reasoning—of learning and acting in accordance with abstract rules. On this model, largely taken for granted in modern societies, acts of selfishness, aggression, and ecological mindlessness are failures of will, moral problems that can be solved by acting in accordance with a higher rationality. But both ancient philosophy and recent scientific scholarship emphasize implicit systems, such as action schemas and perceptual filters that guide behavior and shape human development. In this integrative book, Darcia Narvaez argues that morality goes “all the way down” into our neurobiological and emotional development, and that a person’s moral architecture is largely established early on in life. Moral rationality and virtue emerge “bottom up” from lived experience, so it matters what that experience is. Bringing together deep anthropological history, ethical philosophy, and contemporary neurobiological science, she demonstrates where modern industrialized societies have fallen away from the cultural practices that made us human in the first place. Neurobiology and the Development of Human Morality advances the field of developmental moral psychology in three key ways. First, it provides an evolutionary framework for early childhood experience grounded in developmental systems theory, encompassing not only genes but a wide array of environmental and epigenetic factors. Second, it proposes a neurobiological basis for the development of moral sensibilities and cognition, describing ethical functioning at multiple levels of complexity and context before turning to a theory of the emergence of wisdom. Finally, it embraces the sociocultural orientations of our ancestors and cousins in small-band hunter-gatherer societies—the norm for 99% of human history—for a re-envisioning of moral life, from the way we value and organize child raising to how we might frame a response to human-made global ecological collapse. Integrating the latest scholarship in clinical sciences and positive psychology, Narvaez proposes a developmentally informed ecological and ethical sensibility as a way to self-author and revise the ways we think about parenting and sociality. The techniques she describes point towards an alternative vision of moral development and flourishing, one that synthesizes traditional models of executive, top-down wisdom with “primal” wisdom built by multiple systems of biological and cultural influence from the ground up.

This book discusses how scientific and other types of cognition make use of models, abduction, and explanatory reasoning in order to produce important and innovative changes in theories and concepts. Gathering revised contributions presented at the international conference on Model-Based Reasoning (MBR18), held on October 24–26 2018 in Seville, Spain, the book is divided into three main parts. The first focuses on models, reasoning, and representation. It highlights key theoretical concepts from an applied perspective, and addresses issues concerning information visualization, experimental methods, and design. The second part goes a step further, examining abduction, problem solving, and reasoning. The respective papers assess different types of reasoning, and discuss various concepts of inference and creativity and their relationship with experimental data. In turn, the third part reports on a number of epistemological and technological issues. By analyzing possible contradictions in modern research and describing representative case studies, this part is intended to foster new discussions and stimulate new ideas. All in all, the book provides researchers and graduate students in the fields of applied philosophy, epistemology, cognitive science, and artificial intelligence alike with an authoritative snapshot of the latest theories and applications of model-based reasoning.

Explores the role of artificial intelligence in the development of a claim that morality is person made and rational.This book explores the role of artificial intelligence in the development of a claim that morality is person-made and rational. Professor Danielson builds moral robots that do better than amoral competitors in a tournament of games like the Prisoners Dilemma and Chicken. The book thus engages in current controversies over the adequacy of the received theory of rational choice. It sides with Gauthier and McClennan, who extend the devices of rational choice to include moral constraint. Artificial Morality goes further, by promoting communication, testing and copying of principles and by stressing empirical tests.

In this short and accessible book, Ronald de Sousa shows us that in order to understand what is truly important about our reasoning capacity, we need to change our thinking about what rationality actually is.

Publisher Description

Drawing on the tools of game theory, social choice theory, experimental psychology, and evolutionary theory, Gerald Gaus advances a revised account of public reason liberalism, showing how a free society can secure a moral equilibrium that is endorsed by all, and how a just state respects, and develops, such an equilibrium.
