Because of accelerating technological progress, humankind may be rapidly approaching a critical phase in its career. In addition to well-known threats such as nuclear holocaust, the propects of radically transforming technologies like nanotech systems and machine intelligence present us with unprecedented opportunities and risks. Our future, and whether we will have a future at all, may well be determined by how we deal with these challenges. In the case of radically transforming technologies, a better understanding of the transition dynamics from (...) a human to a "posthuman" society is needed. Of particular importance is to know where the pitfalls are: the ways in which things could go terminally wrong. While we have had long exposure to various personal, local, and endurable global hazards, this paper analyzes a recently emerging category: that of existential risks. These are threats that could case our extinction or destroy the potential of Earth - originating intelligent life. Some of these threats are relatively well known while others, including some of the gravest, have gone almost unrecognized. Existential risks have a cluster of features that make ordinary risk management ineffective. A final section of this paper discusses several ethical and policy implications. A clearer understanding of the threat picture will enable us to formulate better strategies. (shrink)

Focusing on the breakthrough field of molecular engineering--a new technology enabling scientists to build tiny machines atom by atom--the author offers projections on how this technological revolution will affect the future of computer science, space travel, medicine, and manufacturing.

Global Ethics, along with its companion volume Global Justice, will aid in the study of global justice and global ethical issues with significant global dimensions. Some of those issues directly concern what individuals, countries, and other associations ought to do in response to various global problems, such as poverty, population growth, and climate change. Others concern the concepts that are commonly used to discuss such issues, such as "development" and "human rights." And still others concern the legitimacy of various phenomena (...) that structure the global scene, such as national borders, the institutions of national sovereignty and self-determination, and attitudes such as nationalism and patriotism. In recent decades, literature on such issues has started to build up in the Western philosophical tradition. Until now, though, no up-to-date sample of this literature has been available to students and other interested parties. These two books, companion volumes sold separately, fill this gap by providing a sample of the best recent work on these themes. (shrink)

Is morality rational? In this book Gauthier argues that moral principles are principles of rational choice. He proposes a principle whereby choice is made on an agreed basis of cooperation, rather than according to what would give an individual the greatest expectation of value. He shows that such a principle not only ensures mutual benefit and fairness, thus satisfying the standards of morality, but also that each person may actually expect greater utility by adhering to morality, even though the choice (...) did not have that end primarily in view. In resolving what may appear to be a paradox, the author establishes morals on the firm foundation of reason. Gauthier's argument includes an account of value, linking it to preference and utility; a discussion of the curcumstances in which morality is unnecessary; and an application of morals by agreement to relations between peoples at different levels of development and different generations. Finally, he reflects on the assumptions about individuality and community made by his account of rationality and morality. (shrink)

In this book, Weikart helps unlock the mystery of Hitler ’s evil by vividly demonstrating the surprising conclusion that Hitler ’s immorality flowed from a coherent ethic. Hitler was inspired by evolutionary ethics to pursue the utopian project of biologically improving the human race. This ethic underlay or influenced almost every major feature of Nazi policy: eugenics, euthanasia, racism, population expansion, offensive warfare, and racial extermination.

If the greatness of a philosophical work can be measured by the volume and vehemence of the public response, there is little question that Rousseau's Social Contract stands out as a masterpiece. Within a week of its publication in 1762 it was banished from France. Soon thereafter, Rousseau fled to Geneva, where he saw the book burned in public. At the same time, many of his contemporaries, such as Kant, considered Rousseau to be 'the Newton of the moral world', as (...) he was the first philosopher to draw attention to the basic dignity of human nature. The Social Contract has never ceased to be read and debated in the 250 years since its publication. Rousseau's Social Contract: An Introduction offers a thorough and systematic tour of this notoriously paradoxical and challenging text. David Lay Williams offers readers a chapter-by-chapter reading of the Social Contract, squarely confronting these interpretive obstacles. The book also features a special extended appendix dedicated to outlining Rousseau's famous conception of the general will, which has been the object of controversy since the Social Contract's publication in 1762.

Examining the theoretical and empirical status of applied ethics, this volume demonstrates how a pluralistic and democratic society can deal with ethical issues in the light of its moral conscience.
