| 6735 | All motion is relative, so a single body cannot move [Berkeley] |
| Full Idea: There cannot be any motion other than relative; …if there was one only body in being it could not possibly move. | |
| From: George Berkeley (The Principles of Human Knowledge [1710], §112) | |
| A reaction: This seems to agree with with Leibniz in denying the Newton-Clarke idea of absolute space. See Idea 2100. Suppose there were two bodies racing towards one another, when one of them suddenly vanished? |
