Single Idea 8475

[from 'W.V. Quine' by Alex Orenstein, in 5. Theory of Logic / G. Quantification / 4. Substitutional Quantification ]

Full Idea

The substitution view of quantification explains 'there-is-an-x-such-that x is a man' as true when it has a true substitution instance, as in the case of 'Socrates is a man', so the quantifier can be read as 'it is sometimes true that'.

Gist of Idea

The substitution view of quantification says a sentence is true when there is a substitution instance

A Reaction

The word 'true' crops up twice here. The alternative (existential-referential) view cites objects, so the substitution view is a more linguistic approach.
