| 4547 | Plato measured the degree of reality by the degree of value [Nietzsche on Plato] |
| Full Idea: Plato measured the degree of reality by the degree of value. | |
| From: comment on Plato (The Republic [c.374 BCE], 518d) by Friedrich Nietzsche - The Will to Power (notebooks) §572 | |
| A reaction: A most interesting comment. It epitomises the Nietzschean reading of Plato, in which the will to power leads the sense of value, which in turn creates the metaphysics. |
| 20864 | Live in agreement, according to experience of natural events [Chrysippus] |
| Full Idea: The goal of life is to live in agreement, which is according to experience of the things which happen by nature. | |
| From: Chrysippus (fragments/reports [c.240 BCE]), quoted by John Stobaeus - Anthology 2.06a | |
| A reaction: Cleanthes added 'with nature' to Zeno's slogan, and Chyrisppus added this variation. At least it gives you some idea of what the consistent rational principle should be. You still have to assess which aspects of nature should influence us. |
| 2095 | If something has a function then it has a state of being good [Plato] |
| Full Idea: Anything which has been endowed with a function also has a state of being good. | |
| From: Plato (The Republic [c.374 BCE], 353b) | |
| A reaction: 'ought' from 'is'? |
| 2094 | A thing's function is what it alone can do, or what it does better than other things [Plato] |
| Full Idea: The function of anything is what it alone can do, or what it can do better than anything else. | |
| From: Plato (The Republic [c.374 BCE], 353a) | |
| A reaction: I take this concept to be the lynchpin of Aristotle's virtue ethics. Note that it arises earlier, in Plato. Perhaps he should say what it is 'meant to do'. |
| 2129 | Goodness is mental health, badness is mental sickness [Plato] |
| Full Idea: Goodness is a state of mental health, bloom and vitality; badness is a state of mental sickness, deformity and infirmity. | |
| From: Plato (The Republic [c.374 BCE], 444e) | |
| A reaction: A nice statement of the closeness of goodness to health for the Greeks. The key point is that health is a deeply natural concept, which bridges the fact-value divide. |
| 2168 | Clever criminals do well at first, but not in the long run [Plato] |
| Full Idea: Clever criminals are exactly like those runners who do well on the way up the track, and then flag on the way back. | |
| From: Plato (The Republic [c.374 BCE], 613b) | |
| A reaction: Presumably there is some concept of natural justice lurking behind this comparison. Apart from the money, though, it is hard to imagine any professional criminal leading a flourishing life. |
| 12 | If we were invisible, would the just man become like the unjust? [Plato] |
| Full Idea: Glaucon: with a ring of invisibility 'the just man would differ in no way from the unjust'. | |
| From: Plato (The Republic [c.374 BCE], 360c) | |
| A reaction: I think a highly altruistic person would behave well with the ring, but I'm sure Glaucon would claim that these habits would wear off after a while. But I doubt that. |
