Abstract
What does Kant claim to have shown in the Resolution of the Third Antinomy? A recent publication by Bernd Ludwig shows the shortcomings of a fairly broad interpretative consensus around the claim that all that is at stake in the RTA is the mode of logical possibility. I argue that there is a lack of clarity as to what logical possibility, and that the real possibility of transcendental freedom is examined in much of the RTA. Ludwig’s own proposal that Kant shows the real possibility of TF however faces major problems. I formulate an alternative proposal that pays due attention to the claim of the antinomy’s thesis, the evolution of the argument of the RTA, and Kant’s later textual references to it. This also deals with the thorny issue of the relation between practical and TF.
