A state of affairs in which a set of constraints is jointly implicated in maintaining the conditions of existence of the set, or “system.” In a system exhibiting organizational closure, each constraint will depend directly on at least one other constraint for its production and/or maintenance, and will have at least one other constraint that depends on it for its production and/or maintenance; so, the set of constraints exists as a closed network of mutually dependent components. See also, “Self-Determination.”
