Abstract
A recent issue of Research in Phenomenology contains a section on "The Future of Phenomenology," but none of the articles contained therein deals with a future engagement of phenomenology with science, especially mathematical natural science. In this paper, I discuss this engagement that was once so central to phenomenology and suggest lines along which its revival can fruitfully occur. Toward this end, I trace the contours of the Heisenberg-Heidegger exchange and show how recent readings of the Platonic , such as those of Sallis and Derrida, can extend this Auseinandersetzung into new regions.
