This book investigates the conceptual clarity and practical application of Immanuel Kant's humanity formula, specifically the injunction to treat persons as ends in themselves rather than merely as means. Robert Audi, a prominent philosopher, utilizes his extensive background in moral theory to deconstruct these Kantian concepts. He argues that by anchoring these notions outside of strictly Kantian frameworks, one can enhance their utility in contemporary ethical discourse and practical decision-making.

Experts recognize this work as a significant contribution to the clarification of deontological principles in modern ethics. Readers frequently note the analytical rigor of the prose, which serves as a bridge between abstract philosophical theory and applied moral practice.
