Abstract

No understanding of morality has more zealous or influential defenders among academic philosophers than Kant’s. Yet as Michael Rosen demonstrates in The Shadow of God, there is a sense in which Kant’s critics take his conception of freedom more seriously nowadays than his defenders. As a result, contemporary versions of “Kantian ethics” often end up challenging what Rosen calls “the ethics of Kant,” not just the claims of rival moral theories. Rosen supports this surprising conclusion with some powerful arguments, showing that we cannot make sense of Kantian moral philosophy or its extraordinary impact on modern philosophy while detaching it from Kant’s conception of transcendental freedom. But Rosen overstates the continuity between Kant and the Idealist philosophers that he inspired. Thinkers like Schiller, Schelling, and Hegel took Kant’s concept of transcendental freedom far more seriously than defenders of Kantian ethics do today. But precisely because they did so, they felt compelled to address a whole new set of problems, which could be solved only by radically transforming the conception of freedom that they received from Kant.
