8720 | A logic is 'relevant' if premise and conclusion are connected, and 'paraconsistent' allows contradictions [Priest,G, by Friend] |
Full Idea: Priest and Routley have developed paraconsistent relevant logic. 'Relevant' logics insist on there being some sort of connection between the premises and the conclusion of an argument. 'Paraconsistent' logics allow contradictions. | |
From: report of Graham Priest (works [1998]) by Michèle Friend - Introducing the Philosophy of Mathematics 6.8 | |
A reaction: Relevance blocks the move of saying that a falsehood implies everything, which sounds good. The offer of paraconsistency is very wicked indeed, and they are very naughty boys for even suggesting it. |
19494 | Fictionalism allows that simulated beliefs may be tracking real facts [Yablo] |
Full Idea: The fictionalist offers the option that your simulated beliefs and assertions may be tracking a realm of genuine facts, or a realm of what you take to be facts. | |
From: Stephen Yablo (Go Figure: a Path through Fictionalism [2001], 13) | |
A reaction: This means that fictionalism does not have to be an error theory. That is, we aren't mistakenly believing something that we actually made up. Instead we are sensibly believing something we know to be not literally true. Love it. |
19493 | Governing possible worlds theory is the fiction that if something is possible, it happens in a world [Yablo] |
Full Idea: The governing fiction of possible worlds theory says that whenever something is possible, there is a world where it happens. | |
From: Stephen Yablo (Go Figure: a Path through Fictionalism [2001], 05) | |
A reaction: This sounds like the only sensible attitude to possible worlds I can think of. |
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? |
