In this paper, I show that Kant’s solution to the third antinomy is a reply sui generis to the consequence argument. If sound, the consequence argument yields that we are not morally responsible for our actions because our actions are not up to us. After expounding the modal version of the consequence argument advanced by Peter van Inwagen, I show that Kant accepts a key inference rule of the argument as well as a requirement of alternate possibilities for moral blame. (...) Kant must therefore reject one of the premises of the consequence argument to be able to deny its conclusion. Whereas Kantian altered-past compatibilism denies the premise of the consequence argument which states the fixity of the past, Kantian altered-law compatibilism denies the premise that states the fixity of the laws of nature. My analysis shows that Kantian altered-past and altered-law compatibilism are logically consistent, yet it also reveals that they depend on strong metaphysical premises. It must be investigated whether these premises withstand textual scrutiny and whether they are credible in their own right. By way of conclusion, I draw the outlines of this investigation. (shrink)

The aim of this paper is to situate Kant in the debate on free will. Whereas Kantians often assume that Kant's views on free will cannot be brought under any of the headings of this debate, contemporary free will theorists commonly assume that Kant is an incompatibilist of the libertarian type. I argue against both assumptions: Kant can and should be characterized as a compatibilist and more specifically as a soft determinist. After removing some persistent misconceptions about Kant's position in (...) the free will debate, I contend that Kant affirms the truth of determinism, that he rejects the possibility of libertarian free will and that he considers the sort of freedom required for moral responsibility to be compatible with determinism.

In this paper, I give a reconstruction of the so‐called Reinhold–Sidgwick objection and show that Korsgaard‐style Kantian constructivists are committed to two key premises of the underlying argument. According to the Reinhold–Sidgwick objection, the Kantian conception of autonomy entails the absurd conclusion that no one is ever morally responsible for a morally wrong action. My reconstruction of the underlying argument reveals that the objection depends on a third premise, which says that freedom is a necessary condition for moral responsibility. After (...) mapping the common replies to the objection, I demonstrate that none of these replies is available to Kantian constructivists. But they need not be committed to the absurd conclusion that no one is ever morally blameworthy. Kantian constructivists who want to resist the Reinhold–Sidgwick objection are well advised to subject the third premise of the underlying argument to critical scrutiny. (shrink)
