2 ideas
| 20365 | We only see points in motion, and thereby infer movement [Rescher] |
| Full Idea: We perceive motion only as isolated points, and then infer it without actually seeing it. | |
| From: Nicholas Rescher (Scepticism [1980], §112) | |
| A reaction: Note how writing suddenly becomes readable as you slow down on entering a railway station. Is that points suddenly becoming unified? This is an empiricist endorsement of Russell's 'at-at' account of motion. |
| 19384 | Space and time are the order of all possibilities, and don't just relate to what is actual [Leibniz] |
| Full Idea: Space and time taken together constitute the order of possibilities of the one entire universe, so that these orders relate not only to what actually is, but also to anything that could be put in its place. | |
| From: Gottfried Leibniz (Reply to 'Rorarius' 2nd ed [1702], GP iv 568), quoted by Richard T.W. Arthur - Leibniz 7 'Space and Time' | |
| A reaction: A very nice idea. Rather like the 'space of reasons', where all rational thought must exist, space and time are the 'space of existence and action'. Their concepts involve more than relations between what actually exists. |
