NATIONALITY

equitable, and subjects must be compelled to transfer their allegiance to an authority for which they have no attach- ment, and \vhich may be practically a foreign domination. Connected with this theory in nothing except in the common enmity of the absolute state, is the theory which represents nationality as an essential, but not a supreme element in determining the forms of the State. It is distinguished from the other, because it tends to diversity and not to uniformity, to harmony and not to unity; because it aims not at an arbitrary change, but at careful respect for the existing conditions of political life, and because it obeys the laws and results of history, not the aspirations of an ideal future. While the theory of unity makes the nation a source of despotism and revolution, the theory of liberty regards it as the bulwark of self- government, and the foremost limit to the excessive power of the State. Private rights, \vhich are sacrificed to the unity, are preserved by the union of nations. No power can so efficiently resist the tendencies of centralisation, of corruption, and of absolutism, as that community which is the vastest that can be included in a State, which im- poses 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 sove- reignty 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." U
