Return to Motion

The concept of "location" arises in the context of entities which are at rest relative to each other. A thing's location is the place where it is situated. But a moving object is not at any one place—it is in motion. One can locate a moving object only in the sense of specifying the location of the larger fixed region through which it is moving during a given period of time. For instance: "Between 4:00 and 4:05 p.m., the car was moving through New York City." One can narrow down the time period and, correspondingly, the region; but one cannot narrow down the time to nothing in the contradictory attempt to locate the moving car at a single, fixed position. If it is moving, it is not at a fixed position.

The law of identity does not attempt to freeze reality. Change exists; it is a fact of reality. When a thing is changing, that is what it is doing, that is its identity for that period. What is still is still. What is in process is in process. A is A.
