| 4577 | There is no necessity higher than natural necessity, and that is just regularity [Quine] |
| Full Idea: In principle I see no higher or more austere necessity than natural necessity; and in natural necessity, or our attribution of it, I see only Hume's regularities | |
| From: Willard Quine (Necessary Truth [1963], p.76) | |
| A reaction: Presumably this allows logical necessity as a 'lower' necessity, but denies 'metaphysical' necessity, in line with Hume and other tough empiricists. Personally I adore metaphysical necessities, but they are a bit hard to establish conclusively. |
| 7765 | The use of a sentence is its commitments and entitlements [Brandom, by Lycan] |
| Full Idea: Brandom develops a particular conception of 'use', according to which a sentence's use is the set of commitments and entitlements associated with public utterance of that sentence. | |
| From: report of Robert B. Brandom (Articulating Reasons: Intro to Inferentialism [2000]) by William Lycan - Philosophy of Language Ch.6 | |
| A reaction: It immediately strikes me that a sentence could only have commitments and entitlements if it already had a meaning. However, the case of money shows how there might be nothing more to a thing's significance than its entitlements. |
| 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. |
