|Paradoxes||GLU 131 ff
Paradox/Luhmann: paradoxes arise when conditions of its possibility are also conditions of its impossibility simultaneously - Eg.g paradox of Epimenides: This sentence is false - condition of falsehood is also condition of truth.
The paradox does not have therefore the form A = Not A, that would be a contradictory, but not paradoxical statement, but A because not A - paradoxes arise when the observer (each observation is a distinction) asks the question of the unity of the distinction.
Any distinction is paradoxical, because both sides are always simultaneously present. - Paradox: the system observes that its environment is nothing more than an internal product of its operations.
Paradoxes/Luhmann are a problem for the observer, not necessary for the operations of the observing system. - Asymmetrisization can reverse paradoxes.
Paradox/Luhmann/GLU: logical form: not A = not A but because A non-A. - The conditions of possibility are at the same time the conditions of its impossibility. A paradox arises when the observer raises the question of the unity of the distinction. - Every distinction is paradoxical, because both sides are always simultaneously present - they are a problem for the observer - not for the operations of the system.
