"It may seem strange that there can be a structure for breaking all structures and that it can have a precise, limited form, and be built to particular specifications. Yet we have two major examples of such a structure in our experience. One is the mind as imagination. The other is society, progressively recast on the model of the imaginationː organized to shorten the distance between our context-preserving and context-transforming activities and to diminish the dependence of transformation on crisis."
