This article takes up Heidegger's commentary on Rimbaud's Lettres du voyant as the starting point for an exploration of the question of rhythm in Heidegger's thought, and an attempt to situate it within his understanding of technics and Being. Besides pursuing a historical study of the concept of rhythm in Heidegger's work, this article proposes to understand rhythm through the concept of individuation. It responds to the French philosopher Jacques Garelli's critique of Heidegger that the latter ignores the question of individuation and always starts with beings that are already individuated. On the contrary, this article attempts to sketch a theory of individuation of rhythm in Heidegger's proper thinking through a re-interpretation of the Fug - a word he used to translate the Greek word δκη and words derived from it: Joint (Fuge), structure (Gefüge), submission (sich fugen), etc.
