Schematism and Embodiment in Kant's _Opus postumum_

Two intertwined themes run through Kant’s last, unfinished work, known to us as the Opus postumum: the comprehensibility of physics as a science and of human freedom as a causal power.1 The two themes come together in Kant’s theory of self-positing. Although the Opus postumum has received substantial attention in recent decades, there has been an insufficient focus on human embodiment (self-positing) as the bridge between nature and freedom in Kant’s final period. In this paper, I contribute to remedying this defect by showing the centrality of embodiment for Kant’s motivating project of a transition from the metaphysics of natural science to the actual science of physics. Many times in the disordered manuscripts, Kant characterizes this transition in terms of a schematism conceived of as parallel to—or as an extension of—the first Critique schematism. I argue here that Kant’s theory of self-positing places human embodiment in the role of serving as this schematism and making the needed transition.
