Can the phenomena of religion and ethics be reduced to the phenomena of biology? Holmes Rolston says no, and in this sweeping account of the subject, written with considerable verve and clarity, he challenges the sociobiological orthodoxy that would naturalize science, ethics, and religion. The book is thoroughly up to date on current biological thought and is written by one of the most well-respected figures in the philosophy of biology and religion. It is likely to provoke considerable controversy among a wide range of readers in such fields as philosophy, religious studies, and biology, as well as being suitable for courses on science and religion.
