In an age of genetic information and promised enhancements, we wonder what biology can tell us – and what it can't - about how we should live. This superbly clear and sensible book, written by a philosopher trained in biology, is a perfect introduction to this important question. Professor DeMelo-Martin takes us briskly through central social controversies concerning intelligence, aggression, gender, cloning, and genetics, on a guided tour of blind alleys, inaccurate assumptions, and logical mistakes. DeMelo-Martin shows exceptional skill in guiding the reader through complex terrain with balance and objectivity. This book holds rewards for scientists, philosophers, students, and citizens. It provides ideal stepping-off points for classroom discussions and public debates.

Full of common sense, De Melo-Martin's book shows why biological determinism need not undercut moral responsibility. With a rich background in both biology and philosophy, she does a good job of uncovering scientific and ethical flaws in some arguments about cloning and genetic technologies.

In a culture in tension between biotechnological enthusiasms for a post-human future and fearful anti-evolutionist ideologies, de Melo-Martin carefully defends the importance of social and political policies to guide the bio-ethical co-construction of a better life for all. As she argues with edifying balance, only by taking biology seriously can we become serious in appreciating its true benefits and counter the illusory hopes and fears that are often projected upon it.

Professor de Melo-Martin shows herself to be as knowledgeable as she says philosophers and others making ethical and political claims should be. Though many will disagree with her views, it is welcome to have a clearly stated and well argued position with which others can choose to disagree or not.

This book is an empirically rich, theoretically cogent, and sorely needed account of the interdependence of biology and ethics in matters that affect us all.

Mary Mahowald, University of Chicago

Dr. de Melo-Martin offers an insightful and sensible account of the mistakes that philosophers, scientists, and policy makers commit when drawing conclusions about genetics.
