Fora do mundo: lugar e sentido da não-humanidade na ontologia fundamental

This paper outlines a critical interpretation of Martin Heidegger’s thought, focused on the question about the place of non-humanity in the philosophical project of fundamental ontology (1925-1930). By reconstructing briefly the existential concepts of world, history, nature, and life, it aims to investigate the meaning of the relation between human and nonhuman that heideggerian ontology projects from the bond of the existing humanity with being as such. What is the situation of that which, in or outside of man, constitutes itself ontologically against the proper sense of existence as being-in-the-world?
