Kasper Lippert-Rasmussen tackles the major questions concerning luck egalitarianism, providing deep, penetrating and original discussion of recent academic discourses on distributive justice as well as responses to some of the main objections in the literature. He offers a new answer to the "Why equality?" and "Equality of what?" questions, and provides a robust luck egalitarian response to the recent criticisms of luck egalitarianism by social relations egalitarians. This systematic, theoretical introduction illustrates the broader picture of distributive justice and enables the reader to understand the core intuitions underlying, or conflicting with, luck egalitarianism.
