| 23295 | Truth cannot be reduced to anything simpler [Davidson] |
| Full Idea: We cannot hope to underpin the concept of truth with something more transparent or easier to grasp. | |
| From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.21) | |
| A reaction: I suppose precise accounts of correspondence or coherence are offered as replacements for truth, but neither of those ever seem to be possible. I agree with accepting truth as a primitive. |
| 23298 | Neither Aristotle nor Tarski introduce the facts needed for a correspondence theory [Davidson] |
| Full Idea: Neither Aristotle's formula nor Tarski's truth definitions are sympathetic to the correspondence theory, because they don't introduce entities like facts or states of affairs for sentences to correspond. | |
| From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.25) | |
| A reaction: This seems convincing, although it is often claimed that both theories offer a sort of correspondence. |
| 23297 | The language to define truth needs a finite vocabulary, to make the definition finite [Davidson] |
| Full Idea: If the definition of the truth predicate is to be finite (Tarski insisted on this), the definition must take advantage of the fact that sentences, though potentially infinite in number, are constructed from a finite vocabulary. | |
| From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.23) | |
| A reaction: Not sure whether this is in the object language or the meta-language, though I guess the former. |
| 23296 | We can elucidate indefinable truth, but showing its relation to other concepts [Davidson] |
| Full Idea: We can still say revealing things about truth, by relating it to other concepts like belief, desire, cause and action. | |
| From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.21) | |
| A reaction: The trickiest concept to link it to is meaning. I think Davidson's view points to the Axiomatic account of truth, which flourished soon after Davidson wrote this. We can give rules for the correct use of 'true'. |
| 23294 | It is common to doubt truth when discussing it, but totally accept it when discussing knowledge [Davidson] |
| Full Idea: You are following Plato's lead if you worry about the concept of truth when it is the focus of your attention, but you pretend you understand it when trying to cope with knowledge (or belief, memory, perception etc.). | |
| From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.20) | |
| A reaction: Nice to find someone pointing out this absurdity. He says Hume does the same with doubts about the external world, which he ignores when discussing other minds. Belief is holding true; only truths are actually remembered…. |
| 19087 | The meaning or purport of a symbol is all the rational conduct it would lead to [Peirce] |
| Full Idea: The entire intellectual purport of any symbol consists in the total of all modes of rational conduct which, conditionally upon all the possible different circumstances and desires, would ensue upon the acceptance of the symbol. | |
| From: Charles Sanders Peirce (Issues of Pragmaticism [1905], EP ii.246), quoted by Danielle Macbeth - Pragmatism and Objective Truth p.169 n1 | |
| A reaction: Macbeth says pragmatism is founded on this theory of meaning, rather than on a theory of truth. I don't see why the causes of a symbol shouldn't be as much a part of its meaning as the consequences are. |
| 22375 | Moral judgements need more than the relevant facts, if the same facts lead to 'x is good' and 'x is bad' [Foot] |
| Full Idea: It is suggested that anyone who has considered all the facts which could bear on his moral position has ipso facto produced a 'well founded' moral judgement, ...How 'x is good' can be well founded when 'x is bad' is equally well founded is hard to see. | |
| From: Philippa Foot (Moral Arguments [1958], p.96) | |
| A reaction: This seems to be a warning to particularists, if they hope that moral judgements just emerge from the facts. It doesn't rule out physicalist naturalism about morality, if the attitudes we bring to the facts have arisen out of further facts. |
| 22378 | We can't affirm a duty without saying why it matters if it is not performed [Foot] |
| Full Idea: I do not know what could be meant by saying it was someone's duty to do something unless there was an attempt to show why it mattered if this sort of thing was not done. | |
| From: Philippa Foot (Moral Arguments [1958], p.105) | |
| A reaction: The Kantian idea assumes that duty is an absolute, and yet each duty rests on a particular maxim which is going to be universalised. So why should that maxim be universalised, and not some other? |
| 22377 | Whether someone is rude is judged by agreed criteria, so the facts dictate the value [Foot] |
| Full Idea: Whether a man is speaking of behaviour as rude or not rude, he must use the same criteria as anyone else. ...We have here an example of a non-evaluative premise from which an evaluative conclusion can be deduced. | |
| From: Philippa Foot (Moral Arguments [1958], p.104) | |
| A reaction: We would now call 'rude' a 'thick' ethical concept (where 'good' is 'thin'). Her powerful point is, I take it, that evidence is always relevant to judgements of thick concepts, so there is no fact-value gap. 'Rude' has criteria, but 'good' may not. |
| 22376 | Facts and values are connected if we cannot choose what counts as evidence of rightness [Foot] |
| Full Idea: To show that facts and values are connected we must show that some things do and some things don't count in favour of a moral conclusion, and that no one can choose what counts as evidence for rightness or wrongness. | |
| From: Philippa Foot (Moral Arguments [1958], p.99) | |
| A reaction: But what sort of facts might do the job? I can only think of right functioning and health as facts which seem to imply value. Pleasure and misery don't quite get there. |
