Martin Heidegger’s remarks in Being and time on the contrast between the modernly thought corporeality based on a mixture of soul-body, of Cartesian roots, and the existential corporeality from the being-in-the-world of Dasein, are widely known. After that, the major thematization on the body goes back to the Zollikon Seminars. This article looks for new ways of understanding the body based on what Heidegger considers as the ambiguity of truth in the various versions of the lecture “Of the essence of (...) truth”. The truth of the body would allow to understand the body in its erring as Körper and, on the other hand, in as much mystery as Leib. Such a perspective allows a non-unilateral understanding of the body and at the same time opens the possibilities for thinking about it from the Being-in-the-world, as Heidegger had announced it at various moments of his work.
