Abstract
The Thesis of Kant’s Third Antinomy asserts that, because it is “necessary to assume another causality through freedom” in order to derive all the appearances of the world, “causality in accordance with the laws of nature is not the only one” (A444/B472). The argument Kant supplies in support of this, however, has been the subject of interpretative disagreement since at least Schopenhauer, with the most plausible reconstructions being dismissed as question-begging, resting on a conflation relating to the principle of sufficient reason, or attacking a straw-man of the Antithesis position. In this paper, I attempt to provide a novel interpretation of the argument for the Thesis position, one that offers a more compelling case against a charitably interpreted Antithesis position.
