Abstract

: John Haugeland's distinctive approach to Heidegger's ontology rests on taking scientific explanation to be a paradigmatic case of understanding the being of entities. I argue that this paradigm, and the more general account that Haugeland develops from it, misses a crucial component of Heidegger's picture: the dynamic character of being. While this dimension of being first comes to the fore after Being and Time, it should have been present all along. Its absence grounds Heidegger's persistent confusion about whether world is an entity, as well as problems that both Haugeland's Heidegger and Heidegger's Plato run into with the ontological difference. Retrieving the dynamic character of being reveals the proper object of Heidegger's fundamental ontology as well as a distinctive feature of his metaphysics of normativity, which is all but impossible to see if we grasp Heidegger's account through the special case of scientific explanation—at least as usually understood.
