Moral Calculations

What does game theory tell us about rational behavior? Is there such a thing as rational behavior, and if so, is it of any use to us? In this fascinating book, renowned Hungarian economist Laszlo Mero shows how game theory provides insight into such aspects of human psychology as altruism, competition, and politics, as well as its relevance to disparate fields such as physics and evolutionary biology. This ideal guide shows us how mathematics can illuminate the human condition.

The idea that all persons are in some way moral equals or owe each other equal respect and concern has become dogma, and thinkers who question it are often reviled as "Nazis" or "racists". The authors in this volume, however, take a more reflective and critical attitude and try to clarify concepts, showing that the argument is far from obvious.

Originally published in 1987, this book discusses how matters of fact influence moral judgments and also how the judgments themselves influence facts. It demonstrates that ethics is a practical subject affecting our moral assessment of inter-personal behaviour and the conduct of public affairs. It is designed as in introduction to moral philosophy for first-year undergraduates and provides an excellent basis for further study as well as serving as a valuable background text for those whose primary interests are in law, politics, sociology, social history and education.

“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.

Mary Anne Warren explores a theoretical question which lies at the heart of practical ethics: what are the criteria for having moral status? In other words, what are the criteria for being an entity towards which people have moral obligations? Some philosophers maintain that there is one intrinsic property—for instance, life, sentience, humanity, or moral agency. Others believe that relational properties, such as belonging to a human community, are more important. In Part I of the book, Warren argues that no single property can serve as the sole criterion for moral status; instead, life, sentience, moral agency, and social and biotic relationships are all relevant, each in a different way. She presents seven basic principles, each focusing on a property that can, in combination with others, legitimately affect an agent's moral obligations towards entities of a given type. In Part II, these principles are applied in an examination of three controversial ethical issues: voluntary euthanasia, abortion

This exploration of virtue ethics offers an original theory in moral philosophy, identifying a 'moral reflection' as a virtue that has not yet been considered properly by philosophers. The author argues that taking our moral lives seriously must involve some reflection on our moral past.

This book explains the basic concepts of environmental ethics and applies them to global environmental problems. The author concisely introduces basic moral theories, discusses how these theories can be extended to consider the non-human world, and examines how environmental ethics interacts with modern society’s economic approach to the environment.
