11 ideas
343 | The unexamined life is not worth living for men [Socrates] |
Full Idea: The unexamined life is not worth living for men. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - The Apology 38a | |
A reaction: I wonder why? I can see Nietzsche offering aristocratic heroes and dancers as counterexamples. Compare Idea 3798. |
10245 | One geometry cannot be more true than another [Poincaré] |
Full Idea: One geometry cannot be more true than another; it can only be more convenient. | |
From: Henri Poincaré (Science and Method [1908], p.65), quoted by Stewart Shapiro - Philosophy of Mathematics | |
A reaction: This is the culminating view after new geometries were developed by tinkering with Euclid's parallels postulate. |
12729 | The cause of a change is not the real influence, but whatever gives a reason for the change [Leibniz] |
Full Idea: That thing from whose state a reason for the changes is most readily provided is adjudged to be the cause. ...Causes are not derived from a real influence, but from the providing of a reason. | |
From: Gottfried Leibniz (Specimen inventorum [1689], A6.4.1620), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 5 | |
A reaction: Leibniz is not denying that there are real influences. He seems to be offering the thesis which I am pursuing, that the need for explanation is the crucial factor in shaping the structure of our metaphysics. |
339 | Men fear death as a great evil when it may be a great blessing [Socrates] |
Full Idea: No one knows whether death may not be the greatest of all blessings for a man, yet men fear it as if they knew that it is the greatest of evils. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - The Apology 29a | |
A reaction: As a neutral observer, I see little sign of it being a blessing, except as a relief from misery. It seem wrong to view such a natural thing as evil, but it is the thing most of us least desire. |
344 | If death is like a night of dreamless sleep, such nights are very pleasant [Socrates] |
Full Idea: If death is like a night of dreamless sleep it is an advantage, for such nights are very pleasant, and eternity would seem like a single night. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - The Apology 40d | |
A reaction: Dreamless sleep is only pleasant if being awake is unpleasant. Very quiet days are only pleasant if the active days are horrible. A desire for a totally quiet life is absurd. |

Full Idea: One should never return an injustice nor harm another human being no matter what one suffers at their hands. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - Crito 49c | |

Full Idea: One ought not to return a wrong or an injury to any person, whatever the provocation is. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - Crito 49b | |
A reaction: The same as the essential moral teachings of Jesus (see Idea 6288) and Lao Tzu (Idea 6324). The big target is not to be corrupted by the evil of other people. |
341 | Wealth is good if it is accompanied by virtue [Socrates] |
Full Idea: Wealth does not bring about excellence, but excellence makes wealth and everything else good for men. | |
From: Socrates (reports of last days [c.399 BCE]), quoted by Plato - The Apology 30b |
347 | Will I stand up against the law, simply because I have been unjustly judged? [Socrates] |
