The danger, Eco says, is confusing power and force. Force is causality. And causality is reversible. That reversal is called revisionism. On the other hand, to change power is to make a revolution.
Compromises are revisionistic.
Revolution, however, is the sum total of a long series of revisions, the violent overturn of progressive revisions. Society becomes a universe devoid of a center. Everything is periphery. There is no longer the heart of anything. Only romantic terrorists of the Red Brigades thought that the state had a heart and that the heart was vulnerable.
