An international socialism is the stated ideal of most socialists; an international liberalism is the unstated tendency of the liberal. To neither system is it thinkable that men live, not by universal aspirations but by local attachments; not by a "solidarity" that stretches across the globe from end to end, but by obligations that are understood in terms which separate men from most of their fellows-in terms such as national history, religion, language, and the customs that provide the basis of legitimacy.
