“It is enough to regard science as an attempt to humanize things as faithfully as possible; in describing things and their successions, we learn to describe ourselves ever more precisely. Cause and effect—there probably is no such duality; in truth, a continuum stands before us, two segments of which we isolate, just as we perceive movement always only as isolated points and, so, do not really but infer it. The abruptness with which any effects leap out misleads us; it is an abruptness only for us.”
