abstract="This article presents a few remarks concerning the time when revolts and revolutions usually take place. Specifically, the author proposes that a discontented people can be kept cowed by fear, by the use of force, as a general rule, in normal times; but when the instinct of self-preservation is aroused by hunger, cold, etc., the people are much more ready for revolt, and a previously existing discontent will break out openly.
