  Opposed to peace as modus vivendi is what Aron calls, “peace by satisfaction” (Aron 1966, 160 ff). This is a peace that results from a lack of grievances and hostility. In the history of the West, this sort of peace is often linked to what Augustine called the “tranquility of order” (Augustine 1958, Book 19, Chapter 13)  In recent Western thought, this idea often follows Kant in claiming that liberal democracy is the key to such a tranquil order.
