Over the past twenty years, the debate between neutrality and perfectionism has been at the center of political philosophy. Now Perfectionism and Neutrality: Essays in Liberal Theory brings together classic papers and new ideas on both sides of the discussion. Editors George Klosko and Steven Wall provide a substantive introduction to the history and theories of perfectionism and neutrality, expertly contextualizing the essays and making the collection accessible to everyone interested in the interaction between morals and the state.

Prioritarianism holds that improvements in someone's life (gains in well-being) are morally more valuable, the worse off the person would otherwise be. The doctrine is impartial, holding that a gain in one person's life counts exactly the same as an identical gain in the life of anyone equally well off. If we have some duty of beneficence to make the world better, prioritarianism specifies the content of the duty. Unlike the utilitarian, the prioritarian holds that we should not only seek to increase human well-being, but also distribute it fairly across persons, by tilting in favor of the worse off. A variant version adds that we should also give priority to the morally deserving - to saints over scoundrels. The view is a standard for right choice of individual actions and public policies, offering a distinctive alternative to utilitarianism (maximize total well-being), sufficiency (make everyone's condition good enough) and egalitarianism (make everyone's condition the same).
