Creative Evolution is a 1907 book by French philosopher Henri Bergson. Its English translation appeared in 1911. The book proposed a version of orthogenesis in place of Darwin's mechanism of evolution, suggesting that evolution is motivated by the 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.
