Abstract

The paper aims to argue that, despite his imposing elaboration of the question of Being, Heidegger’s major contribution to ontology is a critical one. The restatement of the Seinsfrage rests on presuppositions that are radically non-ontological i.e. phenomenological. Notwithstanding his suspicion of transcendental reduction, Heidegger subscribes to the Husserlian idea of a priority of the sense over the being. This thesis is supported by both the evolution of Heidegger comprehension of ontology and by the pivotal role of the Dasein in the Seinsfrage.
