That all authority in the last analysis rests on opinion is never more forcefully demonstrated than when, suddenly and unexpectedly, a universal refusal to obey initiates what then turns into a revolution. To be sure, this moment – perhaps the most dramatic moment in history – opens the doors wide to demagogues of all sorts and colours, but what else does even revolutionary demagogy testify if not to the necessity of all regimes, old and new, ‘to rest on opinion’? Unlike human reason, human power is not only ‘timid and cautious when left alone’, it is simply non-existent unless it can rely on others; the most powerful king and the least scrupulous of all tyrants are helpless if no one obeys them, that is, supports them through obedience; for, in politics, obedience and support are the same.
- Hannah Arendt (1963) On Revolution (p. 228)
