La parole qui voit, la vision qui parle: De la question du Logos dans «Être et temps»

This essay explores the role played by the Logos in Heidegger's Being and Time. The A. argues that there is an essential albeit implicit link between Heidegger's concept of Logos and the structure of the book. The function of the Logos is to ensure that phenomena are seen as they are, but its theoretical and apophantical character seems to conflict with Heidegger's return to the world of praxis. In order to resolve this tension the A. shows how Heidegger constructs Division I of Being and Time as a double description: the first is naïve and lacks Logos, while the second is reasoned and marked by Dasein and its speech. This dual structure makes different modes of vision change their function and status throughout Division I, so that Logos can ultimately find its proper function as "seeing speech", where speech and vision take place through each other.
