16660 | Are things distinct if they are both separate, or if only one of them can be separate? [Duns Scotus, by Pasnau] |
Full Idea: Later standard theories said that a real distinction obtains between two things that can each exist without the other. For Scotus a real distinction requires only that one of the pair be able to exist without the other. | |
From: report of John Duns Scotus (In Metaphysics [1304], V.5-6 n91) by Robert Pasnau - Metaphysical Themes 1274-1671 12.5 | |
A reaction: His example is the similarity relation, which is independent of the whiteness on which it is based (since the other thing can become non-white). |
16626 | Substance is only grasped under the general heading of 'being' [Duns Scotus] |
Full Idea: No substance is understood in its own right, except in the most universal of concepts, namely of 'being'. | |
From: John Duns Scotus (In Metaphysics [1304], III n. 116), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 07.3 | |
A reaction: This is a fairly standard scholastic pessimism about knowing anything about substance. The modern view suggests that actually scientists know 'substance' pretty well. |
14303 | Truth-functional conditionals have a simple falsification, when A is true and B is false [Peirce] |
Full Idea: The utility of [truth-functional conditionals] is that it puts us in possession of a rule...[namely] The hypothetical proposition may be ...falsified by a single state of things, but only by one in which A [antecedent] is true and B [consequent] is false. | |
From: Charles Sanders Peirce (On the Algebra of Logic [1895], p.218), quoted by Stephen Mumford - Dispositions | |
A reaction: Personally I am rather more interested in verifying conditionals than in falsifying them. I certainly don't accept them until they are falsified, unless they have massive support from surrounding facts. |
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? |
