Benjamin also believes that a more speculative metaphysics would necessitate the abolishment of the sharp distinction between Nature and Freedom—or causal mechanism and moral willing—in Kant’s architectonic. Since it is a specific understanding of “dialectic” which mediates between these two spheres in Kant’s critical system, this entails a speculative rethinking of the Kantian dialectic. This suggests that new possibilities of syllogistic logical relations might themselves be opened up, including what he calls “a certain nonsynthesis of two concepts in another” (SW 1, 106; cf. Weber 2008, 48). The relation of nonsynthesis hinted at here can be seen to inform Benjamin’s understanding of the Idea as a constellation of extremes in the Origin of the German Mourning-Play and of the dialectical image in his mature writings. In this sense, Benjamin’s metacritique of Kant represents an attempt to construct an alternative post-Kantian tradition to that of Hegelian dialectics. It therefore required a new philosophy of history.
