VII. Modern Man and His World Conception
The same is assumed for time. No process takes place at a definite time; it happens in a time-distance relative to another event. In this way, temporal distances in the relation of things and spatial intervals become homogenous and flow together. Time becomes a fourth dimension that is of the same nature as the three dimensions of space. A process in a thing can be determined only as something that takes place in a temporal and spatial distance relative to other events. The motion of a thing becomes something that can be thought only in relation to other things.
