From ontological difference to political difference: Martin Heidegger, left-wing Heideggerian and post-foundationalism. The question of the "post-constitutional"

This paper will seek to develop the general approaches of Martin Heidegger's work based on the introduction made by Gianni Vattimo. Subsequently, the approaches of some left-wing Heideggerian and post-foundational political thought are presented, seeking to find the traces that unite these authors of the contingent foundations of the political and the social, evidencing the ontological difference and its simile to political difference. Finally, and by way of conclusion, the question arises as to whether it is possible to translate the ontological-political difference into a "constitutional difference" that allows laying the foundations of a radical democratic post-constitutionalism that establishes founding values that allow the government of the people, always subject to be defounded again, as a circle of contingent foundations foundationable / unfoundable.
