Peoples able to adapt themselves progressively do not always escape revolution. It was only by means of a revolution that the English, in 1688, were able to terminate the struggle which had dragged on for a century between the monarchy, which sought to make itself absolute, and the nation, which claimed the right to govern itself through the medium of its representatives. The great revolutions have usually commenced from the top, not from the bottom; but once the people is unchained it is to the people that revolution owes its might. It is obvious that revolutions have never taken place, and will never take place, save with the aid of an important fraction of the army. Royalty did not disappear in France on the day when Louis XVI. was guillotined, but at the precise moment when his mutinous troops refused to defend him. It is more particularly by mental contagion that armies become disaffected, being indifferent enough at heart to the established order of things. As soon as the coalition of a few officers had succeeded in overthrowing the Turkish Government the Greek officers thought to imitate them and to change their government, although there was no analogy between the two regimes. A military movement may overthrow a government--and in the Spanish republics the Government is hardly ever destroyed by any other means--but if the revolution is to be productive of great results it must always be based upon general discontent and general hopes. Unless it is universal and excessive, discontent alone is not sufficient to bring about a revolution. It is easy to lead a handful of men to pillage, destroy, and massacre, but to raise a whole people, or any great portion of that people, calls for the continuous or repeated action of leaders. These exaggerate the discontent; they persuade the discontented that the government is the sole cause of all the trouble, especially of the prevailing dearth, and assure men that the new system proposed by them will engender an age of felicity. These ideas germinate, propagating themselves by suggestion and contagion, and the moment arrives when the revolution is ripe. In this fashion the Christian Revolution and the French Revolution were prepared. That the latter was effected in a few years, while the first required many, was due to the fact that the French Revolution promptly had an armed force at its disposal, while Christianity was long in winning material power. In the beginning its only adepts were the lowly, the poor, and the slaves, filled with enthusiasm by the prospect of seeing their miserable life transformed into an eternity of delight. By a phenomenon of contagion from below, of which history affords us more than one example, the doctrine finally invaded the upper strata of the nation, but it was a long time before an emperor considered the new faith sufficiently widespread to be adopted as the official religion. 4.
