Much of social science has been built as a citadel against metaphysics and politics. Faithful to the outlook produced by the modern revolt against an… - Roberto Mangabeira Unger

There is no aspect of a people's collective life that may not have to be abandoned for the sake of meeting a practical challenge, just as there is no aspect they may not have to jettison in order to deal with the visionary appeal in politics. Consequently, the different forms of social life that exist in the world are always less real than they seem; the differences among them subsist on a containment of conflict. If the nations of the world were exposed to constant practical and visionary conflict, none of the differences among them would have any permanence. This does not mean that the peoples would become alike; it does mean that the marks that distinguish their identities would constantly shift hands and that other marks, never before dreamt of, would suddenly appear.

By the structure of society, I mean the institutional and ideological presuppositions that shape the routine practices, conflicts, and transactions in that society, and that are largely taken for granted, even to the point of being invisible, as if they were part of the nature of things. In a free society, this institutional and ideological framework does not present itself as an alien fate beyond the reach of the transformative will and imagination.
