ABSTRACT
But through this complexity, which is due to the complexity of reality itself, we believe that the reader will find his way if he keeps a fast hold on the two principles which we have used as a clue throughout our own researches. The first is that in psychological analysis we must never forget the utilitarian character of our mental functions, which are essentially turned toward action. The second is that the habits formed in action find their way up to the sphere of speculation, where they create fictitious problems, and that metaphysics must begin by dispersing this artificial obscurity. (Bergson, 1910/1988, p. 16)
