This essay aims to clarify the theory of «time» in Negri's thought by considering his two fundamental test on this issue, «The Constitution of Time» and 'Kairòs, Alma Venus, Multitude'. The former text, written in prison in 1982, can be considered the high point of the first period of Negri’s thought, which poses the basis for his «ontological turn». The second text, written during Negri’s period in prison after his Parisian exile, develops a theory of temporality as the realization of his political theory in between 'Insurgencies' and 'Empire'.
