 The rejection of cognitive dualism raises a rather vexing problem for Maimon: if the content of cognition is not to be found in the affection of the merely passive faculty of sensibility, where does the content come from? On the face of it, of course, it seems clear that humans are not wholly responsible for the world of experience, but rather encounter it; Maimon must provide some explanation of the ‘given’ content of experience without appealing to something like the Kantian cognitive dualism he finds so problematic.
