which is the vastest that can be included in a State, which imposes on its members a consistent similarity of character, interest, and opinion, and which arrests the action of the sovereign by the influence of a divided patriotism. The presence of different nations under the same sovereignty is similar in its effect to the independence of the Church in the State. It provides against the servility which flourishes under the shadow of a single authority, by balancing interests, multiplying associations, and giving to the subject the restraint and support of a combined opinion. In the same way it promotes independence by forming definite groups of public opinion, and by affording a great source and centre of political sentiments, and of notions of duty not derived from the sovereign will. Liberty provokes diversity, and diversity preserves liberty by supplying the means of organisation. All those portions of law which govern the relations of men with each other, and regulate social life, are the varying result of national custom and the creation of private society. In these things, therefore, the several nations will differ from each other; for they themselves have produced them, and they do not owe them to the State which rules them all. This diversity in the same State is a firm barrier against the intrusion of the government beyond the political sphere which is common to all into the social department which escapes legislation and is ruled by spontaneous laws. This sort of interference is characteristic 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. The co-existence of several nations under the same State is a test, as well as the best security of its freedom. It is also one of the chief instruments of civilisation; and, as such, it is in the natural and providential order, and indicates a state of greater advancement than the national unity which is the ideal of modern liberalism.
