| 7803 | Modal logic began with translation difficulties for 'If...then' [Lewis,CI, by Girle] |
| Full Idea: C.I.Lewis began his groundbreaking work in modal logic because he was concerned about the unreliability of the material conditional as a translation of 'If ... then' conditionals. | |
| From: report of C.I. Lewis (Symbolic Logic (with Langford) [1932]) by Rod Girle - Modal Logics and Philosophy 12.3 | |
| A reaction: Compare 'if this is square then it has four corners' with 'if it rains then our afternoon is ruined'. Different modalities seem to be involved. We even find that 'a square has four corners' will be materially implied if it rains! |
| 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? |
| 21989 | Man is dominated by money, which is the essence of his alienation [Marx] |
| Full Idea: Money is the alienated essence of man's labour and life, and this alien essence dominates him as he worships it. | |
| From: Karl Marx (On the Jewish Question [1844], p.60), quoted by Peter Singer - Marx 3 | |
| A reaction: Presumably this is inherit in the very nature of money, rather than in the wickedness of capitalists who control it. But money is not inherently alienting for the rich, or for the comfortable bourgeoisie (is it?). |
| 20519 | Marxists say liberal rights are confrontational, and liberal equality is a sham [Marx, by Wolff,J] |
| Full Idea: For Marx liberal rights are egoistic rights of separation: they encourage each individual to view others as limitations to his or her freedom. ....Liberals set up a sham community of 'equal' citizens. | |
| From: report of Karl Marx (On the Jewish Question [1844]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 4 'Marxist' | |
| A reaction: The point is that equality in law does not ensure equal treatment in daily life. I suppose a liberal right can be seen as an opt-out clause for some aspect of society. |
