Many great changes have passed over Europe and have left the fundamentals untouched; the Revolution, which might so easily have remoulded the shape of society, did more and possibly worse: it rebuilt from the foundations. How many unquestioned dogmas were suddenly brought out into broad daylight! All our modern indecision, our confused philosophies, our innumerable doubts, spring from that stirring of the depths. Is property a right? May men own land? Is marriage sacred? Have we duties to the State, to the family? All these questions begin to be raised. A German Pole has denied the sequence of cause and effect. Occasionally a man suddenly rises and asks, “Is there a God?” There is nothing left in reserve for the amusement of posterity. Well, this unexampled violence, which, like the wind on the Red Sea, has bared for a moment things that had lain hidden for centuries—this war of twenty years and its results were due to the fact that the Revolution, which might have started in a different form from almost any European centre, started as fact from France. That France was the agent of the reform is the leading condition of the whole story, for it was her centralisation that made the change so rapid and so effectual, her temperament that framed the abstract formulæ which could spread like a religion, her political position in Europe that led to the crusade against her; and this war in its turn (acting on a Paris that led and governed the nation) produced all the further consequences of the Revolution from the Terror to Waterloo. Let us examine the conditions of the Revolution as a purely French thing, see what it was that made it break out when it did, what guided its course, what gave Paris its position, what led to the wars and the Terror. In the first place, the causes of the Revolutionary movement in France. They were two: First, the immediate material necessity for reform which coincided with the Revolutionary period; secondly, the philosophy which had permeated society for a generation, and which, when once a change was undertaken, guided and controlled the development of that change. As for the material circumstances that led to so urgent a necessity for reform, they may be stated as follows:—The governmental machinery, which had been growing more and more inefficient, had finally broken down; and this failure had been accelerated by a series of natural accidents, the most prominent among them being two successive years of scarcity.
