3. Truth / A. Truth Problems / 2. Defining Truth
Truth cannot be reduced to anything simpler
                        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.
3. Truth / C. Correspondence Truth / 3. Correspondence Truth critique
Neither Aristotle nor Tarski introduce the facts needed for a correspondence theory
                        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.
3. Truth / F. Semantic Truth / 1. Tarski's Truth / c. Meta-language for truth
The language to define truth needs a finite vocabulary, to make the definition finite
                        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.
3. Truth / G. Axiomatic Truth / 1. Axiomatic Truth
We can elucidate indefinable truth, but showing its relation to other concepts
                        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'.
13. Knowledge Criteria / A. Justification Problems / 1. Justification / a. Justification issues
It is common to doubt truth when discussing it, but totally accept it when discussing knowledge
                        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….
