Full Idea
Logically valid sentences are a species of analytic sentence, being true not just in virtue of the meanings of their words, but true in virtue of the meanings of their logical words.

A Reaction
A helpful link between logical truths and analytic truths, which had not struck me before.
| 18751 | Natural language includes connectives like 'because' which are not truth-functional [McGee] |
| 18754 | Logically valid sentences are analytic truths which are just true because of their logical words [McGee] |
| 18755 | Validity is explained as truth in all models, because that relies on the logical terms [McGee] |
| 18753 | An ontologically secure semantics for predicate calculus relies on sets [McGee] |
| 18757 | Soundness theorems are uninformative, because they rely on soundness in their proofs [McGee] |
| 18760 | The culmination of Euclidean geometry was axioms that made all models isomorphic [McGee] |
| 18761 | Second-order variables need to range over more than collections of first-order objects [McGee] |
| 18762 | A maxim claims that if we are allowed to assert a sentence, that means it must be true [McGee] |
