This paper focuses on Anaximander's pinax, the first map according to Western tradition. Its aim is to demonstrate that it is only after the realization of the pinax that it was possible to distinguish between Being and beings in a Heideggerian sense, that is to pose the question of the ontological difference. Consequently, all the history of Western thought is nothing but the history of the raising of cartographical representation, and of reason here embodied, from the dark rigidity of death (...) to the rarefied splendours of Pure Reason.
