In this paper, I problematize the prominence of understanding in Being and Time. In order to demonstrate that the conceptual modification that Nancy does of the relation as "reference" to the relational structure "being-to" is the key element to transform the Heideggerian ontology into an ontology of bodies. To do it, first, I evaluate the implications of the interpretation of language as doxa in the first Heidegger. Then, departing from Nancy, I develop the notion of sense as transitivity of being, supported by the structure "being-to". In third place, I expose another notion of the world, corresponding to the ontological opening without being aprioristic; which works against the ontological preeminence of the human and emphasizes the fundamentality of being-with. Finally, I explain two consequences of this methodological change: the transformation of the existence as creation, instead of comprehension, and of the community as a singular-plural ontological regime.
