|Supervaluation, philosophy: The term goes back to a proposal by B. van Fraassen (“The Journal of Philosophy”, Vol. 63, No. 17, (Sept. 15, 1966), pp. 481-495). If not enough information is available for a decision, the consequences of different possible decisions are compared. Cases which each time produce the truth value t are called "super-true", corresponding for the truth value f as "super-false". One problem is the persistence of truth value gaps. See also truth value clusters, truth value gaps, valuation, evaluation, vagueness, sorites, indeterminacy, dialethism, paradoxes._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Supervaluation/Field: can be used as a kind of semantics with Boolean values: - the Boolean value of a formula is the set of all those (combinations of) candidates of extensions in which the sentence is true - which in turn is a special case of a lattice-value semantics (lattive-valued semantics).
Supervaluation/Field: E.g. "determined p" is true iff p is true in all permissible interpretations of the language._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
