Élan vital, coined by French philosopher Henri Bergson in his 1907 book Creative Evolution, was translated in the English edition as "vital impetus", but is usually translated by his detractors as "vital force". It is a hypothetical explanation for evolution and development of organisms, which Bergson linked closely with consciousness.
It was believed by others that this essence (élan vital) could be harvested and embedded into an inanimate substance and activated with electricity, perhaps taking literally another of Bergson's metaphorical descriptions, the "current of life".
gotta love Wikipedia!
