The premier political philosopher of his day, John Rawls, in three decades of teaching at Harvard, has had a profound influence on the way philosophical ethics is approached and understood today. This book brings together the lectures that inspired a generation of students--and a regeneration of moral philosophy. It invites readers to learn from the most noted exemplars of modern moral philosophy with the inspired guidance of one of contemporary philosophy's most noteworthy practitioners and teachers.

Central to Rawls's approach is the idea that respectful attention to the great texts of our tradition can lead to a fruitful exchange of ideas across the centuries. In this spirit, his book engages thinkers such as Leibniz, Hume, Kant, and Hegel as they struggle in brilliant and instructive ways to define the role of a moral conception in human life. The lectures delineate four basic types of moral reasoning: perfectionism, utilitarianism, intuitionism, and--the ultimate focus of Rawls's course--Kantian constructivism. Comprising a superb course on the history of moral philosophy, they also afford unique insight into how John Rawls has transformed our view of this history.

A distinguished moral philosopher and a leading interpreter of Kant's ethics, Barbara Herman draws on Kant to address timeless issues in ethical theory as well as ones arising from current moral problems, such as obligations to distant need, the history of slavery as it bears on affirmative action, and the moral costs of reparative justice.

Challenging various Kantian orthodoxies, Herman offers a view of moral competency as a complex achievement, governed by rational norms and dependent on supportive social conditions. She argues that the objectivity of duties and obligations does not rule out the possibility of or need for moral invention. Her goal is not to revise Kant but to explore the issues and ask the questions that he did not consider.

Some of the essays involve explicit interpretation of Kant, and others are prompted by ground-level questions. For example, how should we think about moral character given what we know about the fault lines in normal development? If ordinary moral life is saturated by the content of local institutions, how should our accounts of moral obligation and judgment accommodate this?

Barbara Herman argues for a radical shift in the way we perceive Kant's ethics. She convincingly reinterprets the key texts, at once allowing Kant to mean what he says while showing that what Kant says makes good moral sense. She urges us to abandon the tradition that describes Kantian ethics as a deontology, a moral system of rules of duty. She finds the central idea of Kantian ethics not in duty but in practical rationality as a norm of unconditioned goodness. This book both clarifies Kant's own theory and adds programmatic vitality to modern moral philosophy.
