|Vagueness, philosophy: there are descriptions of objects or situations that are necessarily not fully determined. For example, the indication whether a given hue is still red or already orange is not always decidable. It is a property of the language to provide vague predicates. Whether vagueness is a property of the world is controversial. See also sorites, indeterminacy, under-determinateness, intensification, penumbra._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Vagueness/Williamson Puzzles/WilliamsonVsNonfactualism/Field: (Williamson 1994): thesis: for any question there is a simple argument for the conclusion that it has a specific, objective, factual answer. - E.g. Joe is rich or Joe is not rich. - Then there is in each case a fact if he is rich or if he is not rich. Then E.g. Verdi/Bizet is pointless for Williamson. FieldVsWilliamson: E.g. then there must be an inaccessible fact which decides whether the pre-Newtonians mean mass or weight: implausible.
Quantum mechanics: here the Nonfactualism is different._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number. The corresponding books are indicated on the right hand side. ((s)…): Comment by the sender of the contribution.
