We should search all the annals of history in vain for a political revolution of the same character; that character is only to be found in certain religious revolutions. And accordingly it is to them that the French Revolution must be compared, if any light is to be thrown upon it by analogy. Schiller remarks, with truth, in his ‘History of the Thirty Years’ War,’ that the great Reformation of the sixteenth century had the effect of bringing together nations which scarcely knew each other, and of closely uniting them by new sympathies. Thus it was that Frenchmen warred against Frenchmen, while Englishmen came to their assistance; men born on the most distant shores of the Baltic penetrated into the very heart of Germany in order to defend Germans of whose existence they had never heard until then. International wars assumed something of the character of civil wars, whilst in every civil war foreigners were engaged. The former interests of every nation were forgotten in behalf of new interests; territorial questions were succeeded by questions of principle. The rules of diplomacy were involved in inextricable confusion, greatly to the horror and amazement of the politicians of the time. The very same thing happened in Europe after 1789. The French Revolution was then a political revolution, which in its operation and its aspect resembled a religious one. It had every peculiar and characteristic feature of a religious movement; it not only spread to foreign countries, but it was carried thither by preaching and by propaganda. It is impossible to conceive a stranger spectacle than that of a political revolution which inspires proselytism, which its adherents preach to foreigners with as much ardour and passion as they have shown in enacting it at home. Of all the new and strange things displayed to the world by the French Revolution, this assuredly is the newest. On penetrating deeper into this matter, we shall most likely discover that this similarity of effects must be produced by a latent similarity of causes.
