|Signs: signs are recognizable and definable forms that an observer can assign to two domains. The first domain is the repertoire of available forms that allows a distinction of similarity and dissimilarity within this domain, the second domain is a set of objects which also distinguishes between similarity and dissimilarity between these objects as well as distinguishing the objects of the second domain from the forms of the first domain. There are no signs without observation or interpretation. See also language, words, symbols, icons, systems, image, image theory, pictures, assignment._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Sign/Symbol/Fact/Duhem: There can be a connection between an abstract symbol and a concrete fact, but never perfect equality.
E.g. "This wire is flowed through by a current of so and so much amps" does not express a single fact but an immense number of possible facts._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
