3 ideas
| 9283 | Our ancient beliefs can never be overthrown by subtle arguments [Euripides] |
| Full Idea: Teiresias: We have no use for theological subtleties./ The beliefs we have inherited, as old as time,/ Cannot be overthrown by any argument,/ Nor by the most inventive ingenuity. | |
| From: Euripides (The Bacchae [c.407 BCE], 201) | |
| A reaction: [trans. Philip Vellacott (Penguin)] Compare Idea 8243. While very conservative societies have amazing resilience in maintaining traditional beliefs, modern culture eats into them, not directly by argument, but by arguments at fifth remove. |
| 14963 | Surely the past phases of a thing are not parts of the thing? [Broad] |
| Full Idea: It is plainly contrary to common sense to say that the phases in the history of a thing are parts of the thing. | |
| From: C.D. Broad (Examination of McTaggart's Philosophy [1933], I.349-50), quoted by Richard Cartwright - Scattered Objects n18 | |
| A reaction: Nicely expressed! To suggest that me ten years ago is a mere part of some huge me, or that you are only talking to a part of me now, is a very long way indeed from normal usage. |
| 12709 | Motion is not absolute, but consists in relation [Leibniz] |
| Full Idea: In reality motion is not something absolute, but consists in relation. | |
| From: Gottfried Leibniz (On Motion [1677], A6.4.1968), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 3 | |
| A reaction: It is often thought that motion being relative was invented by Einstein, but Leibniz wholeheartedly embraced 'Galilean relativity', and refused to even consider any absolute concept of motion. Acceleration is a bit trickier than velocity. |
