The essays in this volume offer an approach to the history of moral and political philosophy that takes its inspiration from John Rawls. The distinctive feature of this approach is to address substantive normative questions in moral and political philosophy through an analysis of the texts and theories of major figures in the history of the subject: Aristotle, Hobbes, Hume, Rousseau, Kant, and Marx. By reconstructing the core of these theories in a way that is informed by contemporary theoretical concerns, the contributors show how the history of the subject is a resource for understanding present and perennial problems in moral and political philosophy.
