COSMOPOLITAN (Gr. κόσμος, world, and πολίτης, citizen), of or belonging to a “citizen of the world,” i.e. one whose sympathies, interests, whether commercial, political or social, and culture are not confined to the nation or race to which he may belong, opposed therefore to “national” or “insular.” As an attribute the word may be applied to a cultured man of the world, who has travelled widely and is at home in many forms of civilization, to such races as the Jewish, scattered through the civilized world, yet keeping beneath their cosmopolitanism the racial type pure, and also to mark a profound line of cleavage in economic and political thought.
