  • Correspondence Theory
    • Realism about truth
      • Bivalence!
      • A statement is true if it corresponds to the way the world is.
    • The Correspondene Relation
      • Congruence.
        • A truthbearer + correspondent both structured complexes.
          • When correspond, a likeness of structure.
            • True sentence = subject snow and predicate 'is white'
              • Corresponding fact: snow + property of whiteness.
              • Can be a relation of identity or likeness.
      • Correspondence holds between fact and proposition when have same structure, and same constituents in same structural position.
      • Aristotle: a statement is true if it says of what is that it is!
    • Correspondence Without Facts?
      • Tarski provides the core of this.
        • Truth of a sentence determined by relations of reference and satisfaction.
          • Correspondence holds between objects + properties.
            • Disquotation: 'snow' refers to snow.
              • Too vacuous?
                • Field: a causal relation.
                  • Thoughts + sentences have content they do as a result of a representation relation to the external world.
    • Problems
      • Slingshot Argument
        • P and Q denote same fact if: Loically equivalent, or differ only through co-extensive terms.
        • 'S' abbreviates some true sentence. Corresponds to fact that s.
          • Can substitute for this fact: '[The X, such that X is identical to Diogenes and S is identical to [The X, such that X is identical with DIogenes'.
            • So in other words, given the principle of substitution, we can substitute 't' for 's', so long as 't' is true~
            • Basically can get to the fact that grass is green from the fact that snow is white...!
        • If truths correspond to facts, all correspond to the same 'Great Fact'.
          • Or at least - if a statement corresponds to one fact, it corresponds to them all (Red Bluff example!)
      • Logically compound truths
        • Unclear what facts could correspond!
          • Respond - truth makers? Can make multiple truths true!
