REVOLUTION, n. In politics, an abrupt change in the form of
misgovernment. Specifically, in American history, the substitution of
the rule of an Administration for that of a Ministry, whereby the
welfare and happiness of the people were advanced a full half-inch.
Revolutions are usually accompanied by a considerable effusion of
blood, but are accounted worth it -- this appraisement being made by
beneficiaries whose blood had not the mischance to be shed. The
French revolution is of incalculable value to the Socialist of to-day;
when he pulls the string actuating its bones its gestures are
inexpressibly terrifying to gory tyrants suspected of fomenting law
and order.
-- Ambrose Bierce, "The Devil's Dictionary"
