What we should in fact do, is stop allowing philosophers to reflect "on" things. The philosopher creates, he doesn't reflect.
I'm criticized for going back to Bergson's analyses. Actually, to distinguish as Berson did between perception, affection, and action as three kinds of motion is a very novel approach. It remains novel because I don't think it's ever been quite absorbed; it's one of the most difficult, and finest, bits of Bergson's thought. But this analysis applies automatically to cinema: cinema was invented while Bergson's thought was taking shape. Motion was brought into concepts at precisely the same time it was brought into images. Berson presents one of the first cases of self-moving thought. Because it's not enough simply to say concepts possess movement; you also have to construct intellectually mobile concepts. Just as it's not enough to make moving shadows on the wall, you have to construct images that can move by themselves.
