 Henri Bergson (1859–1941) was one of the most famous and influential French philosophers of the late 19th century-early 20th century. Although his international fame reached cult-like heights during his lifetime, his influence decreased notably after the second World War. While such French thinkers as Merleau-Ponty, Sartre, and Lévinas explicitly acknowledged his influence on their thought, it is generally agreed that it was Gilles Deleuze’s 1966 Bergsonism that marked the reawakening of interest in Bergson’s work. Deleuze realized that Bergson’s most enduring contribution to philosophical thinking is his concept of multiplicity. Bergson’s concept of multiplicity attempts to unify in a consistent way two contradictory features: heterogeneity and continuity. Many philosophers today think that this concept of multiplicity, despite its difficulty, is revolutionary. It is revolutionary because it opens the way to a reconception of community.
