Heidegger’s deconstruction of the history of Western metaphysics has been a major influence behind poststructural critiques of modernity as well as more apologetic attempts to maintain a dialogue with historical sources, such as Gadamer’s philosophical hermeneutics. This bifurcation has intensified the ambiguity of Heidegger’s project: was it an attempt to relinquish philosophical ties to the past or a call for a fundamental reinterpretation of them? In this article I argue the latter,focusing my analysis on Heidegger’s notions of appropriation and historicity. (...) On the one hand, appropriation is the hermeneutical event by which ontology is reinfused into a reading of historical sources. On the other hand, historicity is the self-reflexive historical involvement by which we become aware of what contemporary, philosophical conditions necessitate this reengagement. In the end, Heidegger’s critique of metaphysics arises from this self-reflexivity. It deconstructs the prevailing misunderstandings of philosophical sources in order to allow for reinterpretation at a revivified ontological level constantly in view of the question of being.

In modern continental thought, natural science is widely portrayed as an exclusively instrumental mode of reason. The breadth of this consensus has partly preempted the question of how it came to persuade. The process of persuasion, as it played out in Germany, can be explored by reconstructing the intellectual exchanges among three twentieth-century theorists of science, Heidegger, Habermas, and Werner Heisenberg. Taking an iconic Heisenberg as a kind of limiting case of “the scientist,” Heidegger and Habermas each found themselves driven (...) to place new constraints on their previously more capacious assessments of science, especially its capacity to reflect on its method. Tracing how that happened, through archival and historical contextualization and close readings of their texts, lets us make visible Heidegger and Habermas’s intellectual affinities and argumentative parallels, which derived not only from their shared grounding in earlier reactions against positivism, but also from confrontation with contemporary events. The latter included, for Heidegger, the rise of a technically powerful science exemplified by nuclear physics, and for Habermas, post-World War II controversies over science, technology, and their socially critical possibilities.
