Arguing against the grain of much recent scholarly commentary, Rosen asserts that Kant's principles of justice are direct corollaries of the Categorical Imperative and that Kant does not support an absolute or even near-absolute duty of obedience to governments. He also maintains that Kant has principled and important reasons for repudiating a right of revolution and that Kant is not, as he is almost always taken to be, an advocate of the nightwatchman or minimal state. The Kant that emerges from Rosen's pages is an appealing and surprisingly modern philosopher, whose preoccupation with individual freedom still resonates in contemporary political and philosophical debates, and whose attempts to define the proper limits of individual liberty remain relevant even at the end of the twentieth century.
