Indeed, the whole of Professor Bergson's philosophy centres round his conception of real concrete duration and the specific feeling of duration which our consciousness has when it does away with convention and habit and gets back to its natural attitude.

"If a man were to inquire of Nature the reason of her creative activity, and if she were willing to give ear and answer, she would say — 'Ask me not, but understand in silence, even as I am silent and am not wont to speak.'"

What makes hope such an intense pleasure is the fact that the future, which we dispose of to our liking, appears to us at the same time under a multitude of forms, equally attractive and equally possible. Even if the most coveted of these becomes realized, it will be necessary to give up the others, and we shall have lost a great deal.
