Free Will, Determinism, Vitalism

Though the ostensible goal of Time and Free Will is to establish the existence of Free Will, subsequent developments indicate that it has a different, nascent, aim.  For, while the existence of Free Will is central in a Theology according to which humans are the source of Evil, in its maturity, Bergson's project is revealed as Vitalist.  Thus, retrospectively, what he can be understood as trying to accomplish in his earlier work is a demonstration of the irreducibility of Biological principles to mechanistic Physics.  To that end, explaining the independence of Duration from Physicist Time suffices, even if his concept of Free Will remains problematic.  Still, it is not until Matter and Memory, and Creative Evolution, that he more compellingly shows that not only are Vitalism and Physics compatible, the latter is derived from the former.  To that end, whether or not all human behavior is irresistibly determined by Elan Vital, is irrelevant.
