This book investigates whether the existence of plural and conflicting values renders rational ethics impossible. Michael Stocker, a philosopher known for his work on moral psychology and value theory, challenges the traditional philosophical assumption that value conflict is inherently irrational. By examining the historical roots of these concepts in Aristotelian thought, Stocker constructs a framework that reconciles the reality of competing values with the possibility of coherent, rational ethical decision-making.

Scholars in the field of moral philosophy frequently cite this work as a significant contribution to the discourse on value pluralism. Readers often note the academic density of the prose, which is intended for those with a background in ethical theory.
