Single Idea 20295

[filed under theme 19. Language / E. Analyticity / 2. Analytic Truths ]

Full Idea

Frege appealed to definition, or (if 'meaning' is preserved) synonymy: the non-logical analytic truths can be converted to logical truths by substitution of definitions for defined terms, or synonyms for synonyms.

Gist of Idea

All analytic truths can become logical truths, by substituting definitions or synonyms

Source

report of Gottlob Frege (Grundlagen der Arithmetik (Foundations) [1884], §005, 88) by Georges Rey - The Analytic/Synthetic Distinction 1.2

A Reaction

This is a 'dogma of empiricism' attacked by Quine. It seems rather obvious (with hindsight?) that you can smuggle whatever is required to do the job into your definition. Or assert some slightly dubious synonymy.
