- premises
- conclusion
- validity - if prems true then conclusion true
- Conclusion/Hypothesis: The referential view is false.
- Prem1: If RV holds, then CK means the same as SM
- Prem2: If CK means the same as SM, then “CK=SM” means the same as “SM=SM”
- Prem3: “CK=SM” has different cognitive value than “SM=SM”.
- Prem4: if 2 sents have diff cognitive value, then they don’t mean the same thing.
- Prem5: “CK=SM” does not mean the same as “SM=SM”.
- Prem6: “CK” has different meaning from “SM” (principle of compositionality)
- Prem5 contradicts Prem2.
- Prem6 contradicts the referential view (that two singular terms referring to the same thing, mean the same thing.)
