Incommensurable Values

Format:Electronic

Abstract

Values, such as liberty and equality, are sometimes said to be incommensurable in the sense that their value cannot be reduced to a common measure. The possibility of value incommensurability is thought to raise deep questions about practical reason and rational choice as well as related questions concerning topics as diverse as akrasia, moral dilemmas, the plausibility of utilitarianism, and the foundations of liberalism. This entry outlines answers in the contemporary literature to these questions, starting with questions about the nature and possibility of value incommensurability.
