- 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.
- True sentence = subject snow and predicate 'is white'
- When correspond, a likeness of structure.
- A truthbearer + correspondent both structured complexes.
- 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!
- Congruence.
- 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.
- Field: a causal relation.
- Too vacuous?
- Disquotation: 'snow' refers to snow.
- Correspondence holds between objects + properties.
- Truth of a sentence determined by relations of reference and satisfaction.
- Tarski provides the core of this.
- 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...!
- 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'.
- 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!
- Unclear what facts could correspond!
- Slingshot Argument
- Realism about truth
