This essay analyzes the category of “the holy” as developed by Rudolf Otto, examining his division of the holy into rational and non-rational elements. While rational elements of the holy are closely tied to ethics, another aspect of the holy can only be apprehended through sui generis feelings irreducible to other mental states. But how do non-rational elements relate to rational, ethical categories? I trace the distinction between rational and non-rational elements in Otto’s analysis to Kant’s two faculty psychology: the (...) holy is apprehended in one way through feeling, in another way through thought, but a single ultimate reality is experienced.
