[catalogued under 3. Truth / G. Axiomatic Truth / 2. FS Truth Axioms]

Full Idea

The Friedman-Sheard truth system FS is based on compositional theory CT. The axioms of FS are obtained by relaxing the type restriction on the CT-axioms, and adding rules inferring sentences from their truth, and vice versa.

Gist of Idea

Friedman-Sheard is type-free Compositional Truth, with two inference rules for truth

Book Reference

A Reaction

The rules are called NEC and CONEC by Halbach. The system FSN is FS without the two rules.
