9560 | S5 provides the correct logic for necessity in the broadly logical sense [Fine,K] |
Full Idea: S5 provides the correct logic for necessity in the broadly logical sense. | |
From: Kit Fine (Model Theory for Modal Logic I [1978], 151), quoted by Charles Chihara - A Structural Account of Mathematics | |
A reaction: I have no view on this, but I am prejudiced in favour of the idea that there is a correct logic for such things, whichever one it may be. Presumably the fact that S5 has no restrictions on accessibility makes it more comprehensive and 'metaphysical'. |
604 | Knowledge is mind and knowing 'cohabiting' [Lycophron, by Aristotle] |
Full Idea: Lycophron has it that knowledge is the 'cohabitation' (rather than participation or synthesis) of knowing and the soul. | |
From: report of Lycophron (fragments/reports [c.375 BCE]) by Aristotle - Metaphysics 1045b | |
A reaction: This sounds like a rather passive and inert relationship. Presumably knowing something implies the possibility of acting on it. |
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? |
