Bergson argues for free will by showing that the arguments against it come from a confusion of different conceptions of time. As opposed to physicists' idea of measurable time, in human experience life is perceived as a continuous and unmeasurable flow rather than as a succession of marked-off states of consciousness--something that can be measured not quantitatively, but only qualitatively. His conclusion is that free will is an observable fact.
