This article examines the role of the language of Zerrissenheit in the Phenomenology of Spirit, through the Diderotian figure of Rameau’s Nephew. The study highlights the satirical and dialogical form of Diderot’s text as a resource for Hegel’s dialectic, where the experience and language of alienation become critical expressions of modern Bildung. Rameau embodies a disintegrated consciousness whose speech both reveals and enacts alienation, offering Hegel a paradigmatic case of how language simultaneously reflects the dialectical tension between faith (Glauben) and pure insight (reine Einsicht). The thesis advanced here is that both the honest and serious language of the honest consciousness (Moi) and the fragmented speech of the base consciousness (Lui), despite their opposition, in fact articulate the same discursive structure of the Verstand. Hegel’s appropriation of the controversial Le Neveu de Rameau thus not only marks the philosophical overcoming of Enlightenment culture but also underscores the necessity of Enlightenment critique, situating its contradictions as a necessary moment within the broader process of reason (Vernunft).
