Single Idea 17988

[filed under theme 5. Theory of Logic / G. Quantification / 4. Substitutional Quantification ]

Full Idea

The view that all quantification is substitutional is not very plausible in general. Some uses of quantifiers clearly seem to have the function to make a claim about a domain of objects out there, no matter how they relate to the terms in our language.

Gist of Idea

Quantification can't all be substitutional; some reference is obviously to objects

A Reaction

Robust realists like myself are hardly going to say that quantification is just an internal language game.
