Written between 1969 and 1999, these essays in political philosophy examine the standards by which social and political institutions should be justified and appraised. The collection includes the classic essays "Preference and Urgency", "A Theory of Freedom of Expression", and "Contractualism and Utilitarianism", as well as other essays that have not been generally accessible until now. The volume will be essential reading for all studying these topics from the perspective of political philosophy, politics, and law.
