Below there is a link to a paper by Jon Roffe, presented at the Melbourne School of Continental Philosophy Research Day on Spinoza and the Infinite, December 2005: "In lieu of an introduction, let me simply say that my subject here is Alain Badiou’s discussion of Spinoza’s ontology in his masterpiece L’être et l’événement.

He proposes a reading that foregrounds a concept which is as central and celebrated to his philosophy as it is strictly excluded by Spinoza: the void. In short, Badiou contents that for all Spinoza’s effort to offer an ontology of total plenitude, the void returns in his philosophy under the (at first sight) unlikely name of infinite mode. What follows is organised into three moments. I will first give an exposition of Badiou’s intricate critique of Spinoza. Next, I will challenge on a number of points Badiou’s exposition of Spinoza, notably his treatment of infinite and finite.1 It is my contention that Badiou only presents the version of Spinoza amenable to his theoretical orientation, and that a more substantial account of the issues opens up alternatives to the reintroduction of the concept of void in order to provide his philosophy with consistency. Turning then to Deleuze, I will argue that he provides just such an alternative, on the basis of his account of the relationship between modal essence and individual existing modes."
