|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. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. |

Color/vagueness/Wright: shades could be characterized as "accepted" the description as "vague". One could denote something as "red", without being obliged to it. But should one say then that this has both mandatory and permissive moves? Or should we rather conclude that it is wrong to speak of "borderline cases" that permit decisions, but do not prescribe anything?
Definition Vagueness: does not mean the existence of an "inbetween realm".
Vagueness/Wright: is rather the fact that the contrast between what "red" prescribes and that what "not red" prescribes, is not clear everywhere. Also ambiguous shades contrast with unambiguous. ((s) WittgensteinVs, sorites).
Vagueness/convergence/conditions/criteria/Wright: Could there not be a completely permissive discourse? It is clear that the contrast between conditions, that allow an assertion and such for which nothing applies, cannot be completely permissive itself.
Otherwise, there could be no information without additional information. Nothing would be excluded by the "correctness" of such an information ("per se"). There would be nothing then in which this correctness could exist.

Vagueness/sorites/Wright: the existence of borderline cases does not include blurred boundaries - blurred boundaries instead blurry in logical space - Frege/Russell: lack of our language - WrightVs: vague predicates merely partial functions - consistent with a sharp distinction between cases where applicable and where not - not lack of instruction, but demand I that the borders are not drawn - continuity of the world.
