Creative Evolution (L'Evolution créatrice) is a 1907 book by French philosopher Henri Bergson. Its English translation appeare in 1911. The book provides an alternate explanation for Darwin's mechanism of evolution, suggesting that evolution is motivated by an élan vital, a "vital impetus" that can also be understood as humanity's natural creative impulse. The book was very popular in the early decades of the twentieth century, before the Neodarwinian synthesis was developed.
