By abandoning English constitutionalism and creating a new republic based on the rights of the individual, the North Americans introduced a new force in the world. Ideas spread most rapidly when they have found adequate concrete expression. Thus republicanism entered our Romanic/Germanic world... Up to this point, the conviction had prevailed in Europe that monarchy best served the interests of the nation. Now the idea spread that the nation should govern itself. But only after a state had actually been formed on the basis of the theory of representation did the full significance of this idea become clear. All later revolutionary movements have this same goal... This was the complete reversal of a principle. Until then, a king who ruled by the grace of God had been the center around which everything turned. Now the idea emerged that power should come from below... These two principles are like two opposite poles, and it is the conflict between them that determines the course of the modern world. In Europe the conflict between them had not yet taken on concrete form; with the French Revolution it did.
