Abstract
This article aims to expose three ways how the facts of the Commune of Paris has had effect of event in the theoretical work of three authors: Guyau, Badiou and Abensour. For Guyau, present in the facts, it meant the absolute transformation towards a post-foundational and de-normativized thought. For Badiou, the Commune, in addition to be an event in itself, the realization of a form of philosophy based on ontological foundations resulting from the transformation of mathematics in recent centuries. And for Abensour it is evident that this absence of foundations that contemporary philosophy holds is concretized in a way of understanding politics and politics as a way of life in which humans articulate permanent and mutable conventions of organization.
