ABSTRACT Reformed epistemology has reclaimed for contemporary apologetics not only Calvin's notion of sensus divinitatis, but also its negative counterpart—the idea of the corruption of human intellectual capacities through original sin. But while Alvin Plantinga's retrieval of the concept finds some support in Calvin's Institutes, it does not do full justice to the exegetically determined historical dynamism of Calvin's anthropology. I will support my argument with a close reading of Calvin's exegesis of the Fall, which highlights the Christological mediation of true knowledge, and Calvin's identification of disordered imagination as the primary noetic accompaniment of sin. These features deserve the attention of any contemporary retrieval of the noetic effects of original sin, while Calvin's exegesis continues to be of theological interest in itself.
