Stability is not immobility. Prince Klemens von Metternich
Tis plain that there is not in nature a point of stability to be found: everything either ascends or declines. When wars are ended abroad, sedition begins at home, and when men are freed from fighting for necessity, they quarrel through ambition. Sir Walter Scott
All great natures delight in stability; all great men find eternity affirmed in the very promise of their faculties. Ralph Waldo Emerson
True stability results when presumed order and presumed disorder are balanced. A truly stable system expects the unexpected, is prepared to be disrupted, waits to be transformed. Tom Robbins
Success makes men rigid and they tend to exalt stability over all the other virtues; tired of the effort of willing they become fanatics about conservatism. Walter Lippmann
No civilization … would ever have been possible without a framework of stability, to provide the wherein for the flux of change. Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other. Hannah Arendt
