15 ideas
The theory of definite descriptions aims at finding correct truth conditions [Russell, by Lycan]
     Full Idea: Russell's theory of definite descriptions proceeds by sketching the truth conditions of sentences containing descriptions, and arguing on various grounds that they are the correct truth conditions.
     From: report of Bertrand Russell (On Denoting [1905]) by William Lycan - Philosophy of Language Ch.9
     A reaction: It seems important to see both where Russell was going, and where Davidson has come from. The whole project of finding the logical form of sentences (which starts with Frege and Russell) implies that truth conditions is what matters.
Truth-condition theorists must argue use can only be described by appeal to conditions of truth [Dummett]
     Full Idea: To demonstrate the necessity of a truth-conditional theory of meaning, a proponent of such a theory must argue that use cannot be described without appeal to the conditions for the truth of statements.
     From: Michael Dummett (Truth and the Past [2001], 1)
     A reaction: Unlike Dummett, I find that argument rather appealing. How do you decide the possible or appropriate use for a piece of language, if you don't already know what it means. Basing it all on social conventions means it could be meaningless ritual.
The truth-conditions theory must get agreement on a conception of truth [Dummett]
     Full Idea: It is not enough for the truth-condition theorist to argue that we need the concept of truth: he must show that we should have the same conception of truth that he has.
     From: Michael Dummett (Truth and the Past [2001], 2)
     A reaction: Davidson invites us to accept Tarski's account of truth. It invites the question of what the theory would be like with a very robust correspondence account of truth, or a flabby rather subjective coherence view, or the worst sort of pragmatic view.
Davidson's theory of meaning focuses not on terms, but on relations between sentences [Rorty]
     Full Idea: A theory of meaning, for Davidson, is not an assemblage of "analyses" of the meanings of individual terms, but rather an understanding of the inferential relations between sentences.
     From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 6.1)
     A reaction: Put that way, the influence of Frege on Davidson is obvious. Purely algebraic expressions can have inferential relations, using variables and formal 'sentences'.
Top-down semantic analysis must begin with truth, as it is obvious, and explains linguistic usage [Davidson]
     Full Idea: Truth is the essential semantic concept with which to begin a top-down analysis of sentences, since truth, or lack of it, is the most obvious semantic property of sentences, and provides the clearest explanation of judging and conveying information.
     From: Donald Davidson (Truth and Predication [2005], Intro)
     A reaction: [a bit compressed] Presumably this goes with giving sentences semantic priority. The alternative approach is compositional, and is likely to give reference of terms priority over truth of the sentence. But accurate reference is a sort of truth.
Community implies assertability-conditions rather than truth-conditions semantics [Kripke, by Hanna]
     Full Idea: If we take account of the fact that a speaker is in a community, then we must adopt an assertability-conditions semantics (based on what is legitimately assertible), and reject truth-conditional semantics (based on correspondence to the facts).
     From: report of Saul A. Kripke (Wittgenstein on Rules and Private Language [1982]) by Robert Hanna - Rationality and Logic 6.1
     A reaction: [Part of Hanna's full summary of Kripke's argument] This sounds wrong to me. There are conditions where it is agreed that a lie should be told. Two people can be guilty of the same malapropism.
I can understand "He has a beard", without identifying 'he', and hence the truth conditions [Jackson]
     Full Idea: If I hear someone say "He has a beard", and I don't know whether it is Jackson, Jones, or someone else, I don't know which proposition is being expressed in the sense of not knowing the conditions under which what is said is true.
     From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3)
     A reaction: This is the neatest and simplest problem I have encountered for Davidson's truth-conditions account of meaning. However, we probably just say that we understand the sense but not the reference. The strict-and-literal but not contextual meaning.
Truth in a language is explained by how the structural elements of a sentence contribute to its truth conditions [Harman]
     Full Idea: A theory of truth for a language shows how the truth conditions of any sentence depend on the structure of that sentence. The theory will say, for each element of structure, what its contribution is.
     From: Gilbert Harman (Thought [1973], 5.1)
     A reaction: This just seems to push the problem of truth back a stage, as you need to know where the truth is to be found in the elements from which the structure is built.
To understand an utterance, you must understand what the world would be like if it is true [Stalnaker]
     Full Idea: To understand what is said in an utterance of 'The first dog born at sea was a basset hound', one needs to know what the world would have been like in order for what was said in that utterance to be true.
     From: Robert C. Stalnaker (Reference and Necessity [1997], 3)
     A reaction: Put like that, the idea is undeniable. Understanding involves truth conditions. Does mean involve the understanding of the meaning. What do you understand when you understand a sentence? Just facts about dogs? Or something in the sentence?
Externalist semantics are necessary to connect the contents of beliefs with how the world is [Fodor]
     Full Idea: You need an externalist semantics to explain why the contents of beliefs should have anything to do with how the world is.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: Since externalist semantics only emerged in the 1970s, that implies that no previous theory had any notion that language had some connection to how the world is. Eh?
Semantic content is a proposition made of sentence constituents (not some set of circumstances) [Soames]
     Full Idea: The semantic content of a sentence is not the set of circumstances supporting its truth. It is rather the semantic content of a structured proposition the constituents of which are the semantic contents of the constituents of the sentence.
     From: Scott Soames (Why Propositions Aren't Truth-Supporting Circumstance [2008], p.74)
     A reaction: I'm not sure I get this, but while I like the truth-conditions view, I am suspicious of any proposal that the semantic content of something is some actual physical ingredients of the world. Meanings aren't sticks and stones.
There is information if there are symbols which refer, and which can combine into a truth or falsehood [McGinn]
     Full Idea: There is information in a system if there are symbols in it that refer to things and that together form strings that can be true or false.
     From: Colin McGinn (The Mysterious Flame [1999], p.225)
     A reaction: We can also directly apprehend information by perception. Are facts identical with correct information? Can a universal generalisation be information?
Truth conditions will come out the same for sentences with 'renate' or 'cordate' [Lycan]
     Full Idea: A Davidsonian truth theory will not be able to distinguish the meaning of a sentence containing 'renate' from that of one containing 'cordate'.
     From: William Lycan (Philosophy of Language [2000], Ch. 9)
     A reaction: One might achieve the distinction by referring to truth conditions in possible worlds, if there are possible worlds where some cordates are not renate. See Idea 7773.
Truth-conditions as subject-matter has problems of relevance, short cut, and reversal [Yablo]
     Full Idea: If the subject-matter of S is how it is true, we get three unfortunate results: S has truth-value in worlds where its subject-matter draws a blank; learning what S is about tells you its truth-value; negating S changes what it's about.
     From: Stephen Yablo (Aboutness [2014], 02.8)
     A reaction: Together these make fairly devastating objections to the truth-conditions (in possible worlds) theory of meaning. The first-objection concerns when S is false
If truth is deflationary, sentence truth-conditions just need good declarative syntax [Miller,A]
     Full Idea: On a deflationary concept of truth, for a sentence to possess truth-conditions it is sufficient that it be disciplined by norms of correct usage, and that it possess the syntax distinctive of declarative sentences.
     From: Alexander Miller (Philosophy of Language [1998], 5.3)
     A reaction: Idea 6337 gives the basic deflationary claim. He mentions Boghossian as source of this point. So much the worse for the deflationary concept of truth, say I. What are the truth-conditions of "Truth rotates"?
