Autonomy for Kant is not just a synonym for the capacity to choose, whether simple or deliberative. It is what the word literally implies: the imposition of a law on one’s own authority and out of one’s own rational resources. In Kant and the Limits of Autonomy, Shell explores the limits of Kantian autonomy—both the force of its claims and the complications to which they give rise. This book is both a rigorous, philosophically and historically informed study of Kantian autonomy and an extended meditation on the foundation and limits of modern liberalism.

Immanuel Kant’s claim that the categorical imperative of morality is based in practical reason has long been a source of puzzlement and doubt, even for sympathetic interpreters. In The Form of Practical Knowledge, Stephen Engstrom provides an illuminating new interpretation of the categorical imperative, arguing that we have exaggerated and misconceived Kant’s break with tradition. By developing an account of practical knowledge that situates Kant’s ethics within his broader epistemology, Engstrom’s work deepens and reshapes our understanding of Kantian ethics.

John Rawls never published anything about his own religious beliefs, but after his death two texts were discovered which shed extraordinary light on the subject. A Brief Inquiry into the Meaning of Sin and Faith is Rawls’s undergraduate senior thesis, submitted in December 1942, just before he entered the army. The present volume includes these two texts, together with an Introduction by Joshua Cohen and Thomas Nagel, which discusses their relation to Rawls’s published work, and an essay by Robert Merrihew Adams, which places the thesis in its theological context.
