In Book I of the Religion within the Boundaries of Mere Reason Kant offers an explanation of freedom and moral good and evil that is different from that offered in the Groundwork for a Metaphysics of Morals. My primary goal in this paper is to analyze and elucidate this new theory. My secondary goal is to contrast this new theory with the older one that it is replacing. I argue that the new theory, which centers on the idea that evil (...) involves a sort of misprioritizing, enables Kant to get around two problems associated with the older theory. (shrink)
