In these things, therefore, the several nations \vill differ from each other; for they themselves have produced them, and they do not owe them to the State \vhich rules them all. This diversity in the same State is a firm barrier against the intrusion of the government beyond the political sphere \vhich is common to all into the social department which escapes legislation and is ruled by spontaneous la\vs. This sort of interference is character- istic of an absolute government, and is sure to provoke a reaction, and finally a remedy. That intolerance of social freedom which is natural to absolutism is sure to find a corrective in the national diversities, which no other force could so efficiently provide.

Where political and national bound- aries coincide, society ceases to advance, and nations re- lapse into a condition corresponding to that of men who renounce intercourse \vith their fellow-men. The difference between the two unites mankind not only by the benefits
