This chapter addresses the discovery of 'governance' as the complex art of steering multiple agencies, institutions, and systems that are both operationally autonomous from one another and structurally coupled through various forms of reciprocal interdependence. This discovery reflects the dramatic intensification of societal complexity that flows from growing functional differentiation of institutional orders within an increasingly global society and what this implies for the widening and deepening of systemic interdependencies across various social, spatial, and temporal horizons of action. The chapter state the general links between contingent necessity, complexity, and governance and explores this in terms of semiosis, structuration, collibration; as elements in the governance of complexity.
