|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/Language/Gärdenfors: Language is full of vagueness. Since Leibniz, philosophers have dreamed of a precise language.
Gärdenfors thesis: vague concepts are necessary in a language for reasons of cognitive economy. The vagueness results for the most part from the fact that we learn concepts through individual examples and counterexamples.
Explanation of the vagueness:
1. With changing boundary lines of the domains, there is a different probability for the localization of a prototype.
2. Vagueness stems from the changing weighting of the dimensions in one domain. The different weights result in changing contexts. > Perception/Gärdenfors, > prototypes/Gärdenfors, categories/Gärdenfors.
General: cognitive limitations relating to the location of the prototypes and relative weighting of the dimensions explain why terms are generally vague and why categorial perception is omnipresent._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
