Distinguishing non-knowledge

In the following essay, reference is made to the ambivalent position of non -knowledge between ensuring the production of scientific knowledge and risk y decision-making. It will also be shown that this ambivalence is the resul t of system-internal operations and not of external facts, on which "incomp lete constructivism" essentially depends. Finally, it is shown that the con cept of risk marks the interface where modern society oscillates between ex perience (cognition) and action (risk) and that even this state is due to i ts own operations and not to an overall insight into some better option. Ba sically, the argument of this article demonstrates fundamental modes of fra ming uncertainty in modem society.
