The Post-Critical Kant : Understanding the Critical Philosophy through the Opus Postumum

In this book, Bryan Wesley Hall breaks new ground in Kant scholarship, exploring the gap in Kant’s Critical philosophy in relation to his post-Critical work by turning to Kant’s final, unpublished work, the so-called Opus Postumum. This volume provides a powerful alternative to all current interpretations of the Opus Postumum, arguing that Kant’s transition project is best seen as the post-Critical culmination of his Critical philosophy. Hall carefully examines the deep connections between the Opus Postumum and the view Kant develops in the Critique of Pure Reason, to suggest that properly understanding the post-Critical Kant will significantly revise our view of Kant’s Critical period.

"Hall’s study offers a very clear, rigorous, stimulating and original attempt to reconstruct the systematic continuity between Kant’s critical and post-critical philosophy, rightly emphasizing the central meaning of the a priori concept of the ether in OP [Opus Postumum]." - Giovanni Pietro Basile, Hochschule für Philosophie München

In this book, Bryan Wesley Hall breaks new ground in Kant scholarship, exploring the gap in Kant’s Critical philosophy in relation to his post-Critical work by turning to Kant’s final, unpublished work, the so-called Opus Postumum. Although Kant considered this project to be the "keystone" of his philosophical efforts, it has been largely neglected by scholars. Hall argues that only by understanding the Opus Postumum can we fully comprehend both Kant’s mature view as well as his Critical project.

In letters from 1798, Kant claims to have discovered a "gap" in the Critical philosophy that requires effecting a "transition from the metaphysical foundations of natural science to physics"; unfortunately, Kant does not make clear exactly what this gap is or how the transition is supposed to fill the gap. To resolve these issues, Hall draws on the Opus Postumum, arguing that Kant’s transition project can solve certain perennial problems with the Critical philosophy. This volume provides a powerful alternative to all current interpretations of the Opus Postumum, arguing that Kant’s transition project is best seen as the post-Critical culmination of his Critical philosophy. Hall carefully examines the deep connections between the Opus Postumum and the view Kant develops in the Critique of Pure Reason, to suggest that properly understanding the post-Critical Kant will significantly revise our view of Kant’s Critical period.
