Yet it can happen suddenly, unexpectedly, and most frequently in the half-light-of-glimpses, that we catch sight of another visible order which intersects with ours and has nothing to do with it. The speed of a cinema film is 25 frames per second. God knows how many frames per second flicker past in our daily perception. But it is as if, at the brief moments I’m talking about, suddenly and disconcertingly we see between frames. We come upon a part of the visible which wasn’t destined for us.
