Any casual observer of humankind will have been struck by the incongruity with which we may lavish great passion upon the trivial, the frivolous, and the ephemeral or upon collective crusades to which, suddenly and with little reason or reflection, we sacrifice everything. When ordinary men and women, living in the ordinary situations society offers them, move beyond the domain of their most intimate personal relations, they often find little to deserve their surviving intensity—little other than the great historical storms that occasionally sweep them up or fanciful individual escapes that remain disconnected from their daily lives.... A program like the one outlined here remains united to the cause of progressive thought by its emphasis upon the liberation of ordinary people from drudgery and humiliation.

Society will oscillate between long periods of relative stagnation in which state-protected privileges crowd out experiments in the organization of production and brief interludes in which much is destroyed before anything can be created. To perpetuate the practice of innovation, societies must replace such drastic and violent swings with a more constant liquefaction of deals and privileges. They must invent the structures that make structures easier to change.

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.
