This book investigates whether the core objectives of transhumanism—specifically the radical enhancement of human biology and cognition—can actually deliver the promised state of posthuman bliss. Susan B. Levin, a professor of philosophy, utilizes a rigorous analytical framework to examine the philosophical, ethical, and social implications of transhumanist goals. She argues that the movement often relies on flawed assumptions regarding human nature and the societal impact of technological intervention, ultimately questioning the feasibility and desirability of its proposed future.

Scholars in the field of bioethics frequently cite this work for its systematic deconstruction of transhumanist rhetoric. Experts highlight the text as a necessary counter-perspective to the optimistic technological projections often found in popular discourse.
