The Antihumanism of the Young Deleuze: Sartre, Catholicism, and the Perspective of the Inhuman, 1945–48

Gilles Deleuze, along with Jacques Derrida, Michel Foucault, and to a lesser extent Jean-François Lyotard, is considered an avatar of post-structuralism, and often associated with the critique of the concepts of identity and subjectivity. In this essay, I seek to identify the early sources of Deleuze's rejection of the notions of ego and person. In the decade following 1944, one buzzword linked these two notions: humanism. Inspired by the evidential paradigm,¹ and by using archival documents and little-known writings, I suggest why Deleuze's position, and the context in which it developed, can illuminate his mature work, especially his use of the concepts of immanence and univocity.

Deleuze's engagement with anti-humanism—or, to be precise, with "inhumanism" and "impersonalism," the expressions Deleuze and his friends used during the 1940s—is rooted in his radicalization of Jean-Paul Sartre's atheistic philosophy, which he read and discussed between 1943 and 1948. During this period, Deleuze was involved in gatherings organized by Catholic historians of medieval philosophy, including his mentor Maurice de Gandillac and Marie-Madeleine Davy. Gandillac, Davy, and their circles were interested in the existentialist and phenomenological movements, which they occasionally read within a theological framework. By radicalizing the positions detailed in works such as Being and Nothingness (1943) and "Transcendence of the Ego" (1936), Deleuze and his friend Michel Tournier confronted the mutation of Sartre's philosophy that began with his lecture "Existentialism Is a Humanism" (given in 1945 and published as a book the following year). They considered this turn to be incoherent with the core of his philosophy and to have conservative political consequences. This radical stance distinguished them from an older generation of scholars.

Stefanos Geroulanos has shown that opposition to humanism, broadly conceived, emerged in French thought during the 1930s.² To him, the idea that humanism had to be rejected and especially that anthropological questions had to be overcome began in the middle of that decade and reemerged in the later 1940s, with atheist and secular rejections of liberal humanism shadowing Catholic and, to a lesser degree, communist ones. However, I would argue that this ideological transformation in fact slowed somewhat in the decade following 1944. During this period, as Edward Baring has also claimed, most French intellectuals utilized "humanism" to oppose totalitarian and "anti-human" ideologies and to promote doctrines underlining the uniqueness of man as compared to other beings, the centrality of freedom, and the importance of defending human rights.³ Critiques of humanism took a final turn during the 1950s, after the publication of Martin Heidegger's "Letter on Humanism" (1947).⁴ From the late 1950s, and even more so during the 1960s, the question of Being and the analysis of unconscious structures became common among scholars born during the interwar years as ways to overcome humanism and its limitations. During the 1960s, far more than during the 1930s, opposition to humanism and to the centrality of the notion of human subjectivity became radical and explicit; in this period, the term "anti-humanism" took hold, whereas, prior to the 1960s, it was rare and used as a pejorative. Deleuze used "inhumanism" far earlier than other authors of his cohort, already in 1945–48: by comparison, in the early 1950s, both Foucault and Derrida were still relying on different forms of humanism—in the case of the former, Marxist/existentialist; in the case of the latter, existential/spiritualist.⁵ Their turn toward anti-humanism during the mid-1950s was the result of the influence of Heidegger, Jean Hyppolite, Jules Vuillemin, and linguistic structuralism, through Lévi-Strauss.⁶ Not only did Deleuze reach antihumanist positions earlier, before even some of his professors, but he got there along a different way. Sartre's works were a defining theoretical influence at the beginning of Deleuze's intellectual trajectory, and they gave it a peculiar theoretical direction. During the 1940s, authors such as Bergson, Spinoza, and Nietzsche were not yet dear to Deleuze, and they did not occupy the important role that they...
