Abstract
The interpretation of Plato and even more of Aristotle has in the Heidegger´s thought a central role. Heidegger would have understood thanks to the exegesis of the thought that is the pratical dimension that expresses the essence of Dasein, that is the inherent peculiarity of the motility of life, Bewegtheit, grasped in the phronesis and which comes true in the sophia, as dynamis, a being that recognizes itself with the relation to the other-than-self and, even more, that is the possibililty of any relationship.
