Si régulière que soit une physionomie, si harmonieuse qu'on en suppose les lignes, si souples les mouvements, jamais l'équilibre n'en est absolument … - Henri Bergson

Europe is overpopulated, the world will soon be in the same condition, and if the self-reproduction of man is not rationalized... we shall have war.

Time is this very hesitation, or it is nothing. Suppress the conscious and the living (and you can do this only through an artificial effort of abstraction, for the material world once again implies perhaps the necessary presence of consciousness and of life), you obtain in fact a universe whose successive states are in theory calculable in advance, like the images placed side by side along the cinematographic film, prior to its unrolling. Why, then, the unrolling? Why does reality unfurl? Why is it not spread out? What good is time? (I refer to real, concrete time, and not to that abstract time which is only a fourth dimension of space.)17 This, in days gone by, was the starting-point of my reflections. Some fifty years ago I was very much attached to the philosophy of Spencer. I perceived one fine day that, in it, time served no purpose, did nothing. Nevertheless, I said to myself, time is something. Therefore it acts. What can it be doing? Plain common sense answered: time is what hinders everything from being given at once. It retards, or rather it is retardation. It must therefore, be elaboration. Would it not then be a vehicle of creation and of choice? Would not the existence of time prove that there is indetermination in things? Would not time be that indetermination itself? If such is not the opinion of most philosophers, it is because human intelligence is made precisely to take things by the other end. I say intelligence, I do not say thought, I do not say mind. Alongside of intelligence there is in effect the immediate perception by each of us of his own activity and of the conditions in which it is exercised. Call it what you will; it is the feeling we have of being creators of our intentions, of our decisions, of our acts, and by that, of our habits, our characters, ourselves.

We seize, in the act of perception, something which outruns perception itself.
