Single Idea 13232

[filed under theme 5. Theory of Logic / A. Overview of Logic / 4. Pure Logic ]

Full Idea

Logic does not study formal languages for their own sake, which is formal grammar. Logic evaluates arguments, and primarily considers formal languages as interpreted.

Gist of Idea

Logic studies arguments, not formal languages; this involves interpretations

A Reaction

Hodges seems to think logic just studies formal languages. The current idea strikes me as a much more sensible view.
