In this article, I take on a classic objection to Kant’s arguments in the Antinomy of Pure Reason: that the arguments are question-begging, as they draw illicit inferences from claims about representation to claims about reality. While extant attempts to vindicate Kant try to show that he does not make such inferences, I attempt to vindicate Kant’s arguments in a different way: I show that, given Kant’s philosophical backdrop, the inferences in question are not illicit. This is because the transcendental (...) realists that Kant was arguing against have certain philosophical commitments about the nature of ground which, if true, warrant the inferences that Kant draws. This historical corrective not only allows us to better understand Kant’s own thinking in the Antinomies but it also has important upshots for our understanding of Kant’s transcendental idealism.
