nation State is a moral and intellectual whole, whose unifying principle has something of the force of personality. And, just as the metaphysicians have found that, though personality is one of the least ambiguous of words, its conception defies analysis, so, though we all know what we mean by nationality, none of us can define it.

Generally, the common Government has preceded and helped in no small degree to foster the sentiment of nationhood, by which the Government is, in its turn, supported; but occasionally, as in the classic instances of Germany and Italy, the sentiment of nationhood has historically preceded and helped to create the common Government.
