This book investigates the extent to which contemporary bioethical debates rely on unexamined and potentially flawed assumptions regarding the nature of biological reality. Tim Lewens, a philosopher of science, utilizes a rigorous analytical framework to evaluate how biological concepts inform ethical arguments in emerging fields. By scrutinizing the underlying logic of these debates, the author challenges the neutrality of scientific claims in moral discourse.

Scholars in the field of philosophy of science recognize this work as a significant contribution to the intersection of biology and ethics. Readers frequently note the academic density of the prose, which is best suited for those with a background in philosophical argumentation or bioethical theory.
