This paper has three aims. First, to show Kant’s originality in using the celebrated example of the hundred thalers as a criticism of the ontological proof, despite being inspired by a 1780 booklet by Johann Bering. Second, to assess Bering’s and Kant’s different reasons for supporting the truth meant to be illustrated by the case of the thalers. Third, to point out that the debate on the example demands a discussion of the problem of universals. Indeed, the value and scope (...) of Kant’s (and Bering’s) critique of the ontological argument is decisively determined by his position on this problem. (shrink)
