In this paper, I explore the possibility of developing a Kantian account of the ethics of belief by deploying the tools provided by Kant's ethics. To do so, I reconstruct epistemic concepts and arguments on the model of their ethical counterparts, focusing on the notions of epistemic principle, epistemic maxim and epistemic universalizability test. On this basis, I suggest that there is an analogy between our position as moral agents and as cognizers: our actions and our thoughts are subject to (...) the same rational norm. (shrink)
