Durée is indivisible; but this does not imply that past and present are simultaneous. On the contrary, durée is essentially succession: only it is a succession that does not imply a “before” and an “after” external to each other. You can get a clear sense of this by listening to a melody, letting yourself be lulled by the sound and leaving aside all visual images which, in spite of yourself, distort your auditory perception—visual images of musical notes written on paper, visual images of musical instruments being played and stopping, and so on.
