As to his personal belonging to Nazism, I can not deny that he had his membership card of the German Socialist National Political Party, I can not deny that in his black notebooks we find anti-Semitic remarks to a certain extent whether under the implicit or explicit form, but I retain two things:

- on the one hand, I can not deny the extremely fruitful conceptual contributions that heidegger can bring through his new approach to the exercise of philosophy as phenomenological ontology ,
- I can not deny either that we undergo a cognitive bias that develops a tendency to easily forget that the philosopher does not have to be a sage, and that Pythagoras responds that is not "sophos" (wise), but "philo-sophos" to the tyrant of Phlionte; Plato by three times wanted to sympathize with the tyranny of Sycilia to become a philosopher king, and three times he risked his life and was made to explode.

Sartre refused to admit the existence of the Red Guard in China and some camps in the USSR, no one is devoid of all vice or stupidity. I maintain that his belonging to Nazism does not detract from the fruitfulness of his work and I am extremely attentive to the world in which we live and I realize that we owe him a lot and that he influenced us enormously.
