This work, peculiar to all Europe, produced greater ravages in Germany than anywhere else. In Germany, during a certain period, which was summed up by Schiller in his famous drama of The Robbers, robbery and plunder were raised into a protest against property and labor. They appropriated certain elementary ideas, specious and false, apparently just, and in reality absurd, wrapped themselves up in these ideas, and to some extent disappeared in them, assumed an abstract name, and passed into a theoretical state, and in this way circulated among the laborious, suffering, and honest masses, without even the cognizance of the imprudent chemists who prepared the mixture, and the masses that accepted it. Whenever a fact of this nature is produced it is serious. Suffering engenders passion; and while the prosperous blind themselves, or go to deep, the hatred of the unfortunate classes kindles its torch at some sullen or ill-constituted mind which is dreaming in a corner, and sets to work examining society. The examination of hatred is a terrible thing. Hence come, if the misfortune of the age desires it, those frightful commotions, formerly called Jacqueries, by the side of which purely political commotions are child's-play, and which are no longer the struggle of the oppressed with the oppressor, but the revolt of want against comfort. Everything is overthrown at such a time. Jacqueries are the earthquakes of nations. The French Revolution, that immense act of probity, cut short this peril, which was perhaps imminent in Europe toward the close of the eighteenth century. The French Revolution, which was nothing but the ideal armed with a sword, rose, and by the same sudden movement closed the door of evil and opened the door of good. It disengaged the question, promulgated the truth, expelled the miasma, ventilated the age, and crowned the people. We may say that it created man a second time by giving him a second soul,--justice. The nineteenth century inherits and profits by its work, and at the present day the social catastrophe which we just now indicated is simply impossible. Blind is he who denounces it, a fool who fears it, for the Revolution is the vaccine of Jacquerie. Thanks to the Revolution, the social conditions are altered, and the feudal and monarchical diseases are no longer in our blood. There is no middle age left in our constitution, and we are no longer at the time when formidable internal commotions broke out; when the obscure course of a dull sound could be heard beneath the feet; when the earth thrown out from the mole-holes appeared on the surface of civilization; when the soil cracked; when the roof of caverns opened, and monstrous heads suddenly emerged from the ground. The revolutionary sense is a moral sense, and the feeling of right being developed, develops the feeling of duty. The law of all is liberty, which ends where the liberty of another begins, according to Robespierre's admirable definition.
