 First, we are going to look at the concept of vital impulse. In Creative Evolution, Bergson starts out by criticizing mechanism as it applies to the concepts of life and evolution. The mechanistic approach would preclude the possibility of any real change or creativity, as each development would be potentially contained in the preceding ones. However, Bergson continues, the teleological approach of traditional finalism equally makes genuine creation of the new impossible, since it entails, just as mechanism, that the “whole is given.” Therefore, neither mechanism nor strict finalism can give a satisfying account of the phenomenon of change that characterizes life. Nevertheless, Bergson argues, there is a certain form of finalism that would adequately account for the creation of life while allowing for the diversity resulting from creation. It is the idea of an original vital principle. If there is a telos to life, then, it must be situated at the origin and not at the end (contra traditional finalism), and it must embrace the whole of life in one single indivisible embrace (contra mechanism). But, this hypothesis does not yet account for evolution in the diversity of its products, nor does it explain the principle of the nature of life.
