This book investigates how to navigate medical decision-making for patients with disorders of consciousness when clinical certainty is unattainable. Bioethicist L. Syd M. Johnson utilizes empirical data and philosophical inquiry to challenge traditional frameworks regarding moral standing and personhood. The author proposes a novel ethical approach centered on epistemic and ethical risk, providing a structured method for surrogate decision-makers to manage complex, high-stakes medical choices.

Experts recognize this work as a significant contribution to the field of bioethics for its integration of empirical evidence with philosophical rigor. Readers frequently note that the prose is accessible yet intellectually demanding, making it a valuable resource for clinicians and ethicists alike.
