The Heidegger–Deleuze relationship has attracted significant attention of late. This paper contributes to this line of research by examining Deleuze’s claim, recently reiterated and developed by Philip Tonner, that Heidegger offers a univocal conception of Being where there is one sense of Being that is said throughout all entities. Although these authors maintain that this claim holds across Heidegger’s oeuvre, I purposefully adopt a conservative hermeneutical strategy that focuses on two writings from the 1927–1928 period—Being and Time and the following (...) year’s lecture course translated as The Metaphysical Foundations of Logic—and emphasize the lesson of the ontological difference that Being is always the Being of an entity, to argue that with regards to these texts, at least, an alternative equivocal interpretation is possible in which Being is always said differently. The conclusion draws out the implications of this for the relationship between Heidegger’s fundamental ontology and Deleuze’s differential ontology. (shrink)
