16025 | If things change they become different - but then no one thing undergoes the change! [Gallois] |
Full Idea: If things really change, there can't literally be one thing before and after the change. However, if there isn't one thing before and after the change, then no thing has really undergone any change. | |
From: André Gallois (Identity over Time [2011], Intro) | |
A reaction: [He cites Copi for this way of expressing the problem of identity through change] There is an obvious simple ambiguity about 'change' in ordinary English. A change of property isn't a change of object. Painting a red ball blue isn't swapping it. |
16026 | 4D: time is space-like; a thing is its history; past and future are real; or things extend in time [Gallois] |
Full Idea: We have four versions of Four-Dimensionalism: the relativistic view that time is space-like; a persisting thing is identical with its history (so objects are events); past and future are equally real; or (Lewis) things extend in time, with temporal parts. | |
From: André Gallois (Identity over Time [2011], §2.5) | |
A reaction: Broad proposed the second one. I prefer 3-D: at any given time a thing is wholly present. At another time it is wholly present despite having changed. It is ridiculous to think that small changes destroy identity. We acquire identity by dying?? |
16027 | If two things are equal, each side involves a necessity, so the equality is necessary [Gallois] |
Full Idea: The necessity of identity: a=b; □(a=a); so something necessarily = a; so something necessarily must equal b; so □(a=b). [A summary of the argument of Marcus and Kripke] | |
From: André Gallois (Identity over Time [2011], §3) | |
A reaction: [Lowe 1982 offered a response] The conclusion seems reasonable. If two things are mistakenly thought to be different, but turn out to be one thing, that one thing could not possibly be two things. In no world is one thing two things! |
7777 | We accept a metaphor when we see the sentence is false [Davidson] |
Full Idea: It is only when a sentence is taken to be false that we accept it as a metaphor. | |
From: Donald Davidson (What Metaphors Mean [1978], p.40) | |
A reaction: This strikes me as a very nice and true generalisation, even though Davidson mentions "no man is an island" as a counterexample. We thirst for meaning, and switch to a second meaning when the first one looks peculiar. |
7775 | Understanding a metaphor is a creative act, with no rules [Davidson] |
Full Idea: Understanding a metaphor is as much a creative endeavour as making a metaphor, and as little guided by rules. | |
From: Donald Davidson (What Metaphors Mean [1978], p.29) | |
A reaction: This is good news for literature studies courses. Davidson's point is that the metaphor itself only gives you a literal meaning, so it doesn't tell you how to interpret it. It seems an attractive proposal. |
7776 | Metaphors just mean what their words literally mean [Davidson] |
Full Idea: Metaphors mean what the words, in their most literal interpretation, mean, and nothing more. | |
From: Donald Davidson (What Metaphors Mean [1978], p.30) | |
A reaction: This pronouncement must be the result of Davidson anguishing over the truth conditions for metaphors, which are usually either taken to have a 'metaphorical meaning', or to be abbreviated similes. He solved his problem at a stroke! Plausible. |
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? |
