[catalogued under 7. Existence / D. Theories of Reality / 10. Vagueness / f. Supervaluation for vagueness]

Full Idea

For a 'precisification' we take a trivalent interpretation and preserve the T and F values, and then assign all the third values in some way to either T or F.

Clarification

A 'trivalent' interpretation has T, F and a third value, such as 'undetermined'

Gist of Idea

A 'precisification' of a trivalent interpretation reduces it to a bivalent interpretation
