7 ideas
12270 | Being is one [Melissus, by Aristotle] |
Full Idea: Being is one. | |
From: report of Melissus (fragments/reports [c.443 BCE]) by Aristotle - Topics 104b23 | |
A reaction: I can only really understand this in terms of physics, as the belief that ultimately there is one simple theory which explains everything. That project doesn't look terribly promising, despite the lovely simplifications of modern physics. |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
3059 | There is no real motion, only the appearance of it [Melissus, by Diog. Laertius] |
Full Idea: There is no such thing as real motion, but there only appears to be such. | |
From: report of Melissus (fragments/reports [c.443 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.4.3 |
20972 | Joule showed that energy converts to heat, and heat to energy [Joule, by Papineau] |
Full Idea: James Joule established the equivalence of heat and mechanical energy, in the sense of showing that a specific amount of heat will always be produced by the expenditure of a given amount of energy, and vice versa. | |
From: report of James Joule (works [1870]) by David Papineau - Thinking about Consciousness App 4.2 | |
A reaction: This was a major step towards the law of conservation of energy. |
20645 | Heat is a state of vibration, not a substance [Joule] |
Full Idea: We consider heat not as a substance but as a state of vibration. | |
From: James Joule (works [1870]), quoted by Peter Watson - Convergence 01 'Nature's' | |
A reaction: The puzzle is that giving accurate accounts of vibrations, heat and movement require a quantitative substance, energy. But all we have here is movement, and the denial of a substance. Energy is 'nature's currency system'. |
5100 | The void is not required for change, because a plenum can alter in quality [Aristotle on Melissus] |
Full Idea: There is no need for void to be the cause of all change, because it is perfectly possible for a plenum to alter qualitatively (which is something Melissus overlooked). | |
From: comment on Melissus (fragments/reports [c.443 BCE]) by Aristotle - Physics 214a27 | |
A reaction: In modern physics this presumably gives us fluctuations in a force field. Motion is like a cat being digested by a python. The atomist claim that emptiness is needed if anything is to move still has intuitive appeal. |
456 | Nothing could come out of nothing [Melissus] |
Full Idea: If Nothing existed, in no way could anything come into being out of nothing. | |
From: Melissus (fragments/reports [c.443 BCE], B1), quoted by (who?) - where? |
