Robert E. Goodin, a philosopher with many books on political theory, public policy and applied ethics to his credit, defends utilitarianism against its critics and shows how it can be applied most effectively over a wide range of public policies. In discussions of such issues as paternalism, social welfare policy, international ethics, nuclear armaments, and international responses to the environment crisis, he demonstrates what a flexible tool his brand of utilitarianism can be in confronting the dilemmas of public policy in the real world.
