In What is Philosophy?, Deleuze and Guattari make the claim that ‘[i]t may be that believing in this world, in this life, becomes our most difficult task, or the task of a mode of existence still to be discovered on our plane of immanence today. This is the empiricist conversion.’ What are we to make of such a calling? The paper explicates why and in what sense this statement is of exemplary significance both for an appropriate understanding of Deleuze's political (...) thought and for a most timely conceptualisation of politics in a world so clearly defined by immanence, and nothing but immanence. I argue that Deleuze's rigorously constructive approach to the world is not beyond politics, as some recent readings have declared (e.g. those of Badiou and Hallward). Rather, we have to appreciate that in Deleuze and Guattari's demand for a ‘belief in this world’ the political intersects with the dimension of the ethical in such a way that our understanding of both is transformed. Only after this ‘empiricist conversion’ can we truly think of a Deleuzian politics that does justice to a plane of immanence ‘immanent only to itself’. (shrink)

This paper compares two influential but conflicting contemporary models of politics as an activity: those of Hannah Arendt and Alain Badiou. It discovers the fundamental difference between their approaches to politics in their opposing evaluations of the contemporary political significance of the legacy of Plato, Platonism, and the Platonic Idea. Karl Popper’s and Arendt’s analyses of the inherently ideological nature of totalitarianism are contrasted with Badiou’s vindication of an ideological “politics of the Idea.” Arendt and Badiou are shown to share (...) an understanding of politics as a realm for the human deployment of novelty and world-transformation. Their key disagreement concerns the form of activity that accomplishes this deployment. For Arendt, political activity has the basic form of noninstrumental and nonteleological action (praxis), devalued by the Platonic tradition of political philosophy. Badiou, by contrast, follows Plato in regarding politics essentially as a process of production (poiēsis) oriented to an ideal end. (shrink)

This thesis offers a naturalist revision of Alain Badiou’s philosophy. This goal is pursued through an encounter of Badiou’s mathematical ontology and theory of truth with contemporary trends in philosophy of mathematics and philosophy of science. I take issue with Badiou’s inability to elucidate the link between the empirical and the ontological, and his residual reliance on a Heideggerian project of fundamental ontology, which undermines his own immanentist principles. I will argue for both a bottom-up naturalisation of Badiou’s philosophical approach (...) to mathematics and a top-down naturalisation. Articulating my particular understanding of what realism and naturalism should commit us to, I propose a creative fusion of Badiou’s attention to metamathematical results with a structural-informational metaphysics, proposing a ‘matherialism’ uniting the more daring speculative insights of the former with the naturalist and empiricist commitments motivating the latter.
