Motion and Change and Its Perception

“Motion has from an early time been criticised severely, and it has never been defended with much success. (…) Motion implies that what is moved is in two places in one time; and this seems not possible. That motion implies two places is obvious; that these places are successive is no less obvious. But, on the other hand, it is clear that the process must have unity. The thing moved must be one; and, again, the time must be one. If the time were only many times, out of relation, and not parts of a single temporal whole, then no motion would be found. But if there time is one, then, as we have seen, it cannot also be many.”

F. H. Bradley — Appearance and reality (1893)
