Abstract

When Heidegger pursues his destructive interpretation of Leibniz's doctrine of judgment, he identifies a principle of abyssal ground and a concealed metaphysics of truth that undermine the priority of logic with respect to ontology. His reading turns on an account of Leibniz's methodological generation of metaphysical principles and the relation between reason and identity, which, I argue, is at once deeply flawed and extremely productive. This essay pursues the implications of Heidegger's quickly abandoned suggestion that Leibniz's principle of identity is reflexively self-grounding, arguing that this claim makes possible a rigorous interpretation of Leibnizian method as an abyssal logic of repetition. I hold that the identification of such a methodology requires a modified account of the metaphysics of truth operative in Leibniz that reinvigorates Heidegger's reading even while moving beyond his now exhausted trope of a hidden presupposition of subjectivity.
