This article presents a decades-long conflict in the upper echelons of postwar French academic philosophy between the self-identifying “Cartesian” Ferdinand Alquié, professor at the Sorbonne, and the “Spinozist” Martial Gueroult of the Collège de France. Tracking the development of this rivalry serves to illuminate the historical drama that occurred in France as phenomenology was integrated into the Cartesian tradition and resisted by a commitment to rationalism grounded in a specifically French understanding of Spinozism. Over the course of Alquié and Gueroult's (...) polemic, however, we nevertheless witness a shared concern to preserve philosophy from the reductive tendencies of historicism and its possible assimilation to theology. What is more, the ultimate impasse of this conflict continues to inform the most innovative projects in French thought in the wake of structuralism and the “theological turn” of French phenomenology.

This thesis seeks to understand the nature of and relation between science and philosophy articulated in the early work of the French philosopher Gilles Deleuze. It seeks to challenge the view that Deleuze’s metaphysical and metaphilosophical position is in important part an attempt to respond to twentieth century developments in the natural sciences, claiming that this is not a plausible interpretation of Deleuze’s early thought. The central problem identified with such readings is that they provide an insufficient explanation of the (...) nature of philosophy’s contribution to the encounter between philosophy and science that they discern in Deleuze’s work. The philosophical, as opposed to scientific, dimension of the position attributed to Deleuze remains obscure. In chapter 1, it is demonstrated that this question of philosophy’s contribution to intellectual life and of how to differentiate philosophy from the sciences is a live one in Deleuze’s early thought. An alternative, less anachronistic interpretation of the parameters of Deleuze’s early project is offered. The remaining chapters of the thesis examine the early Deleuze’s understanding of the divergence between philosophy and science. Chapter 2 gives an account of Deleuze’s metaphilosophy, alongside a reconstruction of his largely implicit early understanding of science. The divergent intellectual processes and motivating concerns that account for Deleuze’s understanding of the differentiation of science and philosophy are thus clarified. In chapter 3, Deleuze’s use of mathematical and physical concepts is examined. It is argued that these concepts are used metaphorically. In chapter 4, the association between modern science and the Deleuzian concept of immanence that has been proposed by some Deleuze scholars is examined and ultimately challenged. The thesis concludes with some reflections on the significance of Deleuze’s early work for contemporary debates concerning the future of continental philosophy and the nature of philosophy more generally.
