Afterword

The proposal that Hume woke Kant by challenging the principle of sufficient reason lets us understand why Kant saw Hume as an opponent of speculative theodicy, since speculative theodicy was grounded in that principle. It thereby also allows us to understand Kant’s turn to Rousseau, who “saved Providence,” and the turn from speculative to practical metaphysics that characterizes Kant’s critical philosophy. The difficulty people have had in understanding Kant’s account of how Hume roused him has to do with the fact that they wish to avoid his transcendental idealism, since that account implies that Hume woke him by putting him on the path to transcendental idealism. To understand the Critique, we must understand it as the “execution” of Hume’s problem understood as the problem of metaphysics.
