This volume investigates whether the moral objections and endorsements surrounding human enhancement technologies are grounded in rigorous philosophical reasoning or influenced by underlying psychological biases. The authors, a collaborative team of international ethicists, utilize current scientific research and established moral philosophy to evaluate the implications of using medical procedures and pharmaceuticals to surpass human biological limits. By dissecting the arguments for and against enhancement, the text provides a structured framework for navigating the intersection of emerging biotechnology and ethical theory.

Experts recognize this work as a significant contribution to the field of bioethics, noting its balanced approach to a polarized subject. Readers frequently highlight the academic density of the prose, which makes it a suitable resource for students and scholars of moral philosophy.
