#### [catalogued under 5. Theory of Logic / G. Quantification / 2. Domain of Quantification]

Full Idea

The 'logica magna' [of the Fregean tradition] has quantifiers ranging over a fixed domain, namely everything there is. In the Boolean tradition the domains differ from interpretation to interpretation.

Gist of Idea

Big logic has one fixed domain, but standard logic has a domain for each interpretation
