Single Idea 22965
[filed under theme 27. Natural Reality / D. Time / 1. Nature of Time / d. Time as measure
]
Full Idea
Since time is the measure of change, it will be measure of rest also.
Gist of Idea
Time measures rest, as well as change
Source
Aristotle (Physics [c.337 BCE], 221b07)
Book Ref
Aristotle: 'Physics Books III and IV', ed/tr. Hussey,Edward [OUP 1983], p.48
A Reaction
The thought seems to be that change leads us to a system of temporal measurement, which is then available fro measurement periods of rest. But totally eventless time would be a problem. Aristotle had no clocks.
