|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.

Definition mark/Luhmann: difference of signifier and signified - not "the designated"! - Character: a form with two sides: one always uses the inner side of the form. -> Spencer-Brown.

Character/world/ontology/Saussure/Luhmann: signs and signified are both linguistically internal. - One could not have words, if one does not mean something with them. - On the other hand: you can make any decisions without anything getting doubled. - The sign means what it means in use, so the meaning of apple, is not the apple itself - Ambiguous. Sense of the apple or speaker's intention?

sign/re-entry/Luhmann: Re-entry: the distinction between signifier and signified as a distinction is the sign. - The sign is the unity of distinction. - The signifier is not the sign. - This corresponds with a 2nd order observation. - I designate characters. - I designate my distinction - blind spot: the user of the sign cannot really use the unit as a unit. - For this he would need the concept of the sign._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
