What awakened Kant from his dogmatic slumber? On the traditional narrative, he was awakened by Hume's challenge to our cognition of causal connections. A more recent narrative claims that he was awakened by Hume's challenge to our cognition of non-logical connections more generally. In this paper, I argue that a key part of Kant's awakening was far wider-reaching: he came to realize that all dogmas must be abandoned. An oft-overlooked technical notion, dogmas are non-logical principles cognizable to unaided human reason. (...) I detail how Kant repudiated dogmas by the mid-1760's in engaging with his German predecessor, Christian Crusius. This repudiation lays the foundation for his critical project. For once liberated of dogmas, reason must look beyond itself for the principles that would enable rational cognitionof non-logical connections. (shrink)
