The question for the who of being-with: Heidegger in his Being and Time

In order to radicalize, extend and locate in its most genuine possibility the existential word being-with, this Paper tries to think and open its horizon from phenomenological analyzes developed by Heidegger I Section of the Book Being and Time ( 25-27), respecting and accepting its own and intrinsic limitations and despite the seemingly negative character that surrounds this existential. For this reason, through a phenomenological interpretation, it has been tried to enhance the possible yields of a being-with-property. To this end, the emphasis has been placed on the need to interpret the Heideggerian opus magnum from the horizon of the Selfhood of Dasein. In order to think a being-with-property the conclusion of this Paper would like to point out two routes: a) to take the Selfhood of Dasein as necessary and sufficient condition to think a being-with-property, being that the Selfhood of Dasein constitutes an executive possibility of existing where this entity is what it is; b) to establishes a relationship between being-with, freedom and Selfhood in the which has its thematic foundation in a presumed equality of pre-ontological order.
