Logic is the science of pure time, just as geometry is the science of pure space.

In the past one would not have dared make such a statement. Just as geometry seemed to deal only with stable shapes and not with transformations and deformations, logic seemed to deal with the static modalities of thought and among its connections only with the syllogistic—and that as a matter of privilege. But geometry has become the science of moving spatial shapes; everywhere mathematics has brought in the fluxional element; on the whole, science considers rest as an extreme instance of motion. Logic too—even leaving aside mathematical logic— cannot keep its classical image. For thought cannot confine itself— and confines itself even less than mathematics does—to reflecting the static. While a circle can still be looked upon as a simple circle and not deformed by topological vision, a form of thought is always condensed time.
