The student uprisings of May 1968 reinforced Badiou's commitment to the far Left, and he participated in increasingly militant groups, such as the Union des communistes de France marxiste-léniniste (UCFml). To quote Badiou himself, the UCFml is "the Maoist organization established in late 1969 by Natacha Michel, Sylvain Lazarus, myself and a fair number of young people". During this time, Badiou joined the faculty of the newly founded University of Paris VIII/Vincennes-Saint Denis which was a bastion of counter-cultural thought. There he engaged in fierce intellectual debates with fellow professors Gilles Deleuze and Jean-François Lyotard, whose philosophical works he considered unhealthy deviations from the Althusserian program of a scientific Marxism.
