A mystery, a figment—and all-powerful. It conditions the exterior world, it is motion married to and mingled with the existence of bodies in space, and with the motion of these. Would there then be no time if there were no motion? No motion if no time? We fondly ask. Is time a function of Space? Or space of time? Or are they identical? Echo answers. Time is functional, it can be referred to as action; we say a thing’s “brought about” by time. What sort of thing? Change! Now is not then, here not there, for between them lies motion. But the motion by which one measures time is circular, is in a closed circle; and might almost equally well be described as rest, as cessation of movement—for the there repeats itself constantly in the here, the past in the present. Furthermore, as our utmost effort cannot conceive a final limit either to time or in space, we have settled to think of them as eternal and infinite—apparently in the hope that if this is not very successful, at least it will be more so than the other.
