L'asimmetria del principio: principio di ragione ed evento

For something to happen there must be an asymmetry. This is what both Hegel and Heidegger tried to reflect upon, the former through the unity of being and nothingness and the notions of ontological difference, the latter through ἀλήθεια and event. The discussion about this thesis revolves around the way in which they both conceived of: a) identity, referring, above all, to those systems of abstract identity – which, for Hegel, are represented by Parmenides and Spinoza; b) the principle of reason, referring to logical, rational truths and factual or contingent truths. “Asymmetry of the principle” means that every “coming into being”, every phenomenalisation, that is, every event, is the result of a diffraction of the undifferentiated identity. It means, therefore, that the principle can only be conceived as differential.
