Abstract

Two issues are at the core of a seemingly never-ending debate about Groundwork III: First, does Kant in GMS III still think he has to deduce the moral law partly from non-moral presuppositions by making a transition from theoretical to practical freedom, as Schönecker argues? Or does Kant already regard the categorical imperative as grounded in a fact of reason, as Puls argues? It is, secondly, no less unclear what exactly is meant by the “deduction” Kant mentions in three places in GMS III. While Puls claims that Kant is referring to the deduction of the idea of freedom from the unquestionable consciousness of pure practical reason, Schönecker contends that GMS III is ultimately about the deduction of the categorical imperative. Schönecker takes issue with Puls’s position as developed, and Puls replies.
