This book is about the respective roles of intuition and reasoning in ethics. It responds to a number of well-known philosophers and psychologists, and proposes a new perspective radical in its moderation. It examines in depth the work of the philosopher Joshua Greene and the psychologist Jonathan Haidt. With the so-called empirical turn in ethics, much work has been done to try to isolate the role of reason and intuition in forming our moral judgements, with Haidt and Greene leading the research programmes and attracting much of the professional and public attention, and many others following. The current view shared by both camps is that intuition is largely the driver of our moral judgements a view summed up in Haidts slogan intuition first, strategic reasoning second. Haidt believes we have to live with this and accept it. Greene does not: he contends that our intuitions, while suitable for the environments in which we evolved, are worthless in the modern, global, technological age, and to avoid ethical disaster we must learn to adopt reason as the arbiter of moral truth. This book steers a middle course between these two positions and is therefore of great interest to philosophers and psychologists alike. Intuition and reason, and different conceptions of them, lie behind many significant discussions in recent philosophical ethics and moral psychology. One effect of those discussions has been the insertion of a wedge between the two notions. In this engaging and fascinating book, McGee and Foster make a thought-provoking case for removing that wedge. - Professor Roger Crisp, Professor of Moral Philosophy, University of Oxford I wanted to cheer all the way through this beautifully written book one that is both incisive and profoundly humane. So much moral philosophy is ensnared in simple rationalism or simple intuitionism: this book argues that intuition and reason are not just at times compatible, in a sort of uneasy compromise, but that each is always essential to the proper functioning of the other. Its takedown of so much utilitarianism is long overdue. It embraces what can be learnt from neuroscience and at the same time appeals to morality in the practice of life, not just in the seminar room. A book that should be on every intelligent readers shelves. - Dr Iain McGilchrist, author of The Master and His Emissary and The Matter with Things What is the role of reason and intuition in ethics? This spirited and thought[1]provoking book makes the case that the relationship between reason and intuition has been fundamentally mischaracterized. And bewarethere is a degree of pain in store for those of us whove relied on (and enjoyed) elaborate philosophical thought experiments, such as the famous trolley problem. Theyre next to useless, the authors contend, in providing us with any genuine moral insight. - David Edmonds, author of Would You Kill the Fat Man?.
