Abstract
This article delineates the core concerns and motivations of the ontological work of Gilles Deleuze, and is intended as a programmatic statement for a general philosophical audience. The article consists of two main parts. In the first, two early writings by Deleuze are analysed in order to clarify his understanding of ontology broadly, and to specify the precise aim of his understanding of being in terms of difference. The second part of the article looks at the work of Heidegger and Derrida in order to distinguish Deleuze's conceptions of ontology and difference from theirs. A final section clarifies Deleuze's efforts to undertake the construction of an ontology divergent from the dominant tradition and in contrast to the emphasis on the closure of metaphysics in the thought of Heidegger and Derrida.
