The central philosophical challenge of metaethics is to account for the normativity of moral judgment without abandoning or seriously compromising moral realism. In Morality in a Natural World, David Copp defends a version of naturalistic moral realism that can accommodate the normativity of morality. Moral naturalism is often thought to face special metaphysical, epistemological, and semantic problems as well as the difficulty in accounting for normativity. In the ten essays included in this volume, Copp defends solutions to these problems. Three of the essays are new, while seven have previously been published. All of them are concerned with the viability of naturalistic and realistic accounts of the nature of morality, or, more generally, with the viability of naturalistic accounts of reasons.

What is morality and what is the source of our moral ideas? Philosophers have explored these questions for centuries, suggesting that both emotion and reason play roles but failing to explain how and why Homo sapiens developed these ideas. Author Roger Moseley argues that evolutionary forces that optimize human welfare provide the missing explanation. Morality: A Natural History presents a multi-disciplinary analysis of the topic and reveals a common thread among the seemingly diverse fields of religion, neuroscience, experimental psychology and game theory, child development, evolution and animal behavior, and anthropology and sociology. When humans first appeared, a simple self-interested survival morality sufficed. As societies became more complex, however, rules of behavior became necessary to limit conflict and promote cooperation. The brain evolved, producing language that allowed the articulation of moral ideas which were codified and enforced by religion and social forces. No species lasts forever, and it is at our peril today that we neglect those evolved moral values of cooperation, altruism, truthfulness, and empathy. Rooted in scientific evidence and interspersed with personal anecdotes and humorous observations, Moseley provides a unique perspective on the natural history of morality – how it appeared, evolved, and continues to evolve today. Morality: A Natural History is essential reading for academics and laypersons alike who seek to understand the origin and essence of human morality.

The essays in this collection belong to the tradition of naturalism in ethics. The tradition goes back to the beginnings of moral philosophy in ancient Greek thought. Its program is to explain moral thought and action as wholly natural phenomena. Its aim, in other words, is to explain such thought and action without recourse to either a reality separate from that of the natural world or volitional powers that operate independently of natural forces. Its greatest exponent in ancient thought was Aristotle. In modern thought Hume and Freud stand out as the most influential contributors to the tradition. All three thinkers made the study of human psychology fundamental to their work in ethics. All three built their theories on studies of human desires and emotions and assigned to reason the role of guiding the actions that spring from our desires and emotions toward ends that promise self-fulfillment and away from ends that are self-destructive. The collection's essays draw inspiration from their ideas. Its twelve principal essays are arranged to follow the lead of Aristotle's and Hume's ethics. The first three survey and examine general theories of emotion and motivation. The next two focus on emotions that are central to human sociability and that contemporary Anglo-American philosophers discuss under the rubric of reactive attitudes. Turning to distinctively cognitive powers necessary for moral thought and action, the sixth and seventh essays discuss the role of empathy in moral judgment and defend Bernard Williams's controversial account of practical reason. The final five essays use the studies in moral psychology of the previous chapters to treat questions in ethics and social philosophy. The treatment of these questions exemplifies the implementation of a naturalist program in these disciplines.

What make someone a good human being? Is there an objective answer to this question, an answer that can be given in naturalistic terms? For ages philosophers have attempted to develop some sort of naturalistic ethics. Against ethical naturalism, however, notable philosophers have contended that such projects are impossible, due to the existence of some sort of 'gap' between facts and values. Others have suggested that teleology, upon which many forms of ethical naturalism depend, is an outdated metaphysical concept. This book argues that a good human being is one who has those traits the possession of which enables someone to achieve those ends natural to beings like us. Thus, the answer to the question of what makes a good human being is given in terms both objective and naturalistic. The author shows that neither 'is-ought' gaps, nor objections concerning teleology pose insurmountable problems for naturalistic virtue ethics. This work is a much needed contribution to the ongoing debate about ethical theory and ethical virtue.

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

A Morally Complex World covers the methodology of moral theology; basic concepts such as conscience and moral agency; natural law and moral norms; how the Bible can be used in Christian ethics; how to dialogue on contested ethical issues; how to consider sin and moral failure; and how to mediate moral principles and moral teaching in a pastorally sensitive manner in concrete life situations.

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”.

What rational justification is there for conceiving of all living things as possessing inherent worth? In Respect for Nature, Paul Taylor draws on biology, moral philosophy, and environmental science to defend a biocentric environmental ethic in which all life has value. Without making claims for the moral rights of plants and animals, he offers a reasoned alternative to the prevailing anthropocentric view--that the natural environment and its wildlife are valued only as objects for human use or enjoyment. Respect for Nature provides both a full account of the biological conditions for life--human or otherwise--and a comprehensive view of the complex relationship between human beings and the whole of nature. This classic book remains a valuable resource for philosophers, biologists, and environmentalists alike--along with all those who care about the future of life on Earth. A new foreword by Dale Jamieson looks at how the original 1986 edition of Respect for Nature has shaped the study of environmental ethics, and shows why the work remains relevant to debates today.

The place of religion in society has changed profoundly in the last few centuries, particularly in the West. In what will be a defining book for our time, Taylor takes up the question of what these changes mean, and what, precisely, happens when a society becomes one in which faith is only one human possibility among others.

The environmental crisis besieges morality with unanswered questions and ethical dilemmas, requiring fresh examination of nature's value, animal rights, activism, and despair.
