Valentin Cartillier - The (re)commencement of Aleatory Materialism: reading the appearances of the void across the oeuvre of Louis Althusser
In the light of the series of posthumous publications of the works of Louis Althusser, the concept of the void is increasingly being recognised as a central tenet of his theoretical output by scholars such as François Matheron, G.M Goshgarian, Isabel Garo, André Tosel, and Stefano Pippa. However, given the heterogeneity of its appearances across the different domains of his thought, it has proven a difficult, yet fecund, concept to understand. This is in part due to Althusser’s own insistence that the void is not a philosophical concept that can be systematised. At times it is used as a theory of historical change, other times it implicitly scaffolds his theory of subjectivity, it dictates the purpose of philosophy in relation to scientific and political practice, and most explicitly, it serves as the basis for his theory of aleatory materialism. This thesis will not content itself with simply a descriptive reading of the appearances of the void but instead understand these appearances and transformations across different domains as a disclosure of the structure of his late concept of aleatory materialism. This structure, consisting of atoms (elements), the void, and the swerve (encounter, or clinamen) will serve to elaborate the two central theses at stake in this reading. The first is that the contingent encounters of elements within the void discloses its structure, while the second, which results from the first, contends that there exists an ‘ontological break,’ in Althusser’s work. To reduce our line of inquiry to a single question: How do the appearances of the void throughout his work help us understand the primacy of contingency posited by aleatory materialism and the ontological break? This thesis will therefore track the appearances, transformations, and conceptual uses of the void in Althusser’s thought in order to interrogate the theoretical and practical consistency of aleatory materialism across what can easily appear to be very disparate works. It will consist of a close, slightly altered chronological rereading of Althusser’s oeuvre, beginning with an exposition of his later concept of aleatory materialism which will then serve as the basis to track changes in how the void is formulated from early on in his career, in a master’s thesis on the G.W.F. Hegel to his later work on Lenin and Machiavelli.
