Back matter: "A welcome attempt to resurrect an older tradition of moral and political reflection and to show its relevance to our current condition." -- John Gray "Cosmopolitanism is... of wide interest-invitingly written and enlivened by personal history... Appiah is wonderfully perceptive and levelheaded about this tangle of issues." -- Thomas Nagel "Elegantly provocative." -- Edward Rothstein "[Appiah's] belief in having conversations across boundaries, and in recognizing our obligations to other human beings, offers a welcome prescription for a world still plagued by fanaticism and intolerance." -- Kofi A. Annan, former United Nations secretary-general "[Appiah's] exhilarating exposition of his philosophy knocks one right off complacent balance... All is conveyed with flashes of iconoclastic humor." -- Nadine Gordimer, winner of the 1991 Nobel Prize in Literature "An attempt to redefine our moral obligations to others based on a very humane and realistic outlook and love of art... I felt like a better person after I read it, and I recommend the same experience to others." -- Orham Pamuk, winner of the 2006 Nobel Prize in Literature.

Publisher's Note: In the past few decades, scientists of human nature—including experimental and cognitive psychologists, neuroscientists, evolutionary theorists, and behavioral economists—have explored the way we arrive at moral judgments. They have called into question commonplaces about character and offered troubling explanations for various moral intuitions. Research like this may help explain what, in fact, we do and feel. But can it tell us what we ought to do or feel?

In Experiments in Ethics, the philosopher Kwame Anthony Appiah explores how the new empirical moral psychology relates to the age-old project of philosophical ethics. Some moral theorists hold that the realm of morality must be autonomous of the sciences; others maintain that science undermines the authority of moral reasons. Appiah elaborates a vision of naturalism that resists both temptations. He traces an intellectual genealogy of the burgeoning discipline of “experimental philosophy,” provides a balanced, lucid account of the work being done in this controversial and increasingly influential field, and offers a fresh way of thinking about ethics in the classical tradition.

Appiah urges that the relation between empirical research and morality, now so often antagonistic, should be seen in terms of dialogue, not contest. And he shows how experimental philosophy, far from being something new, is actually as old as philosophy itself. Beyond illuminating debates about the connection between psychology and ethics, intuition and theory, his book helps us to rethink the very nature of the philosophical enterprise.

Diversifying Syllabi: Thesis: Those affected by mental disorders whose actions are episodically influenced by their disorder are often overlooked by philosophers of moral and ethical responsibility. Allen gives us reasons for thinking it is inappropriate to either: a) “summarily exclude people with mental problems out of the universe of moral agents, reducing them to the status of rocks, trees, animals, and infants” b) “include the group on the false assumption that their moral lives are precisely like the paradigmatic moral lives of the epistemically-sound and well-regulated people never personally touched by a mental condition” We must explore a revised approach to moral and ethical responsibility and obligation for this group.

Abstract: Many accounts of informed consent in medical ethics claim that it is valuable because it supports individual autonomy. Unfortunately there are many distinct conceptions of individual autonomy, and their ethical importance varies. A better reason for taking informed consent seriously is that it provides assurance that patients and others are neither deceived nor coerced. Present debates about the relative importance of generic and specific consent (particularly in the use of human tissues for research and in secondary studies) do not address this issue squarely. Consent is a propositional attitude, so intransitive: complete, wholly specific consent is an illusion. Since the point of consent procedures is to limit deception and coercion, they should be designed to give patients and others control over the amount of information they receive and opportunity to rescind consent already given.
