| 291 | Don't assume that wisdom is the automatic consequence of old age [Plato] |
| Full Idea: Don't assume that wisdom is the automatic consequence of old age. | |
| From: Plato (Laches [c.381 BCE], 188b) | |
| A reaction: I have taught teenagers who seemed to me wiser than nearly all the adults I have ever met. |
| 6215 | 'Contingent' means that the cause is unperceived, not that there is no cause [Hobbes] |
| Full Idea: For contingent, men do not mean that which hath no cause, but that which hath not for cause any thing that we perceive, as when a traveller meets a shower, they both had sufficient causes, but they didn't cause one another, so we say it was contingent. | |
| From: Thomas Hobbes (Of Liberty and Necessity [1654], §95) | |
| A reaction: Contingent nowadays means 'might not have happened', or 'does not happen in all possible worlds'. Personally I share Hobbes' doubts about the concept of contingency, and this is quite a good account of the misunderstanding. |
| 293 | Being unafraid (perhaps through ignorance) and being brave are two different things [Plato] |
| Full Idea: To be unafraid (like a small child who doesn't understand the danger) and to be brave are two quite different things. | |
| From: Plato (Laches [c.381 BCE], 197b) |
| 1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
| Full Idea: Archelaus was the first person to say that the universe is boundless. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
| 5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
| Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
| A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
