[10] of these voluntary acts which may be compared to reflex movements, and he has restricted freedom to moments of crisis. But he does not seem to have noticed that the process of our free activity goes on, as it were, unknown to ourselves, in the obscure depths of our consciousness at every moment of duration, that the very feeling of duration comes from this source, and that without this heterogeneous and continuous duration, in which our self evolves, there would be no moral crisis. The study, even the close study, of a given free action will thus not settle the problem of freedom. The whole series of our heterogeneous states of consciousness must be taken into consideration. In other words, it is in a close analysis of the idea of duration that the key to the problem must be sought.
