[catalogued under 3. Truth / A. Truth Problems / 2. Defining Truth]

Full Idea

It is plain that the distinction between object and metalanguage is required for the definability of truth.

Gist of Idea

Any definition of truth requires a metalanguage


Volker Halbach (Axiomatic Theories of Truth [2011], 11)

Book Reference

Halbach,Volker: 'Axiomatic Theories of Truth' [CUP 2011], p.148

A Reaction

Halbach's axiomatic approach has given up on definability, and therefore it can seek to abandon the metalanguage and examine 'type-free' theories.
