| 14725 | Maybe motion is a dynamical quantity intrinsic to a thing at a particular time [Sider] |
| Full Idea: There is an alternative to the Russellian 'at-at' theory of motion, according to which dynamical quantities are intrinsic to times. Whether and how an object is moving at a time is a fact about what that object is like then. | |
| From: Theodore Sider (Four Dimensionalism [2001], 2.2) | |
| A reaction: I think I find this quite appealing, because there is too much of a tendency to think of objects as passive and inert, with laws, forces, motions etc. imposed from the outside. But nature is active and dynamic. However, motion can't be wholly intrinsic. |
