The question of time is one of the most significant problems to emerge in political philosophy. This article presents a radical critique of the notion of time in traditional philosophy from the perspective of Antonio Negri's materialist phenomenology. It demonstrates that the "materialist turn" was achieved only with a deep review of this concept. Negri deconstructed the metaphysical and phenomenological assumptions that were founded on the idea of time to build a new ontology to establish a new relationship between the subject, time,  the temporal,  and temporality.
