[en] Crossings, crises, men-bridges : paths on the performative precipitation of language in the face of the disproportion of living. The paper intends to act as a reflection on the forms of life that compare their design with the limits of the languages and the terrain of "game" assigned to them, thus not presenting a radicalism, but an ethic centered on the vulnerability of its position of enunciation. The arts and the sciences live the paradox of the investiture of a mediating tension. The strenuous commitment to the new has exhausted the excessive institutionalization of this mandate, withdrawing into a culture of the extreme that seems to hold in contempt any "humanistic" centrality. Instead, the latter rises up again, where civilization appears in the disproportion of a landscape that is opposed to any preventive linguistic territorialization. It is for this reason that our paper starts from a reflection on the cultures expressed by the Arctic peoples about the "nature" of living.
