|Information, information theory: A character or a character combination contains information when it is clear to the recipient that this character or the character combination appears instead of another possible character or a possible character combination. The supply of possible characters determines to a part the probability of the occurrence of a character from this supply. In addition, the expected probability of the appearance of a character can be increased by already experienced experiences of regularities. The amount of information transmitted by a character depends on the improbability of the occurrence of the character.|

Definition information/Maturana/Luhmann: Vs genetic information: Information is always a moment of communication, only within a system. - It works as an information when it comes to finding the next operation - ((s) not circular: - "A works as A, when ...-" - Information: is not -"data" - that would be "transmission theory" - two aspects: 1 from which is selected - 2. this and nothing else is selected - only within a system possible - the system determines what information is - E.g. socialist planned economy: only performance - capitalist: unemployment numbers no information - no information without communication - but communication may repeat itself, information does not - understanding: does not exist outside communication.
