We might place nations in a scale of nationhood. The scale would correspond roughly to one in which they were arranged according to the degree to which the public good is the end, and the desire of it the motive, of men’s actions; this in turn would correspond to a scale in which they were arranged according to the degree of development and diffusion of the national consciousness, of the idea of the nation or society as a whole; and this again to one in which they were arranged according to the degree of intercourse they have had with other nations. At the bottom of the scale would stand the people of Thibet, the most isolated people of the world; near them the Chinese, who also have until recently been almost entirely excluded from international intercourse. Such peoples have a national consciousness and sentiment which is extremely vague and imperfect. They do not realise their weakness, their strength or their potentialities, but have an unenlightened pride without aspiration for a higher form of national life. A little above them would stand Russia, which has remained for so long outside the area of European international life. While at the top of the scale would be those nations which have borne their part in all the strain and stress and friction of European rivalry and intercourse. These degrees of international intercourse have been very largely determined by geographical conditions; isolation, and consequent backwardness in national evolution, being in nearly every case due to remoteness of position. The most important factor of modern times making for more rapid social evolution is probably the practical destruction or overcoming of the barriers between peoples; for thus all peoples are brought into the international arena, and their national spirit is developed through international intercourse and rivalry. It is this increasing contact and intercourse of peoples, brought about by the increased facilities of communication, which has quickened the growth of national self-consciousness throughout all the world and has made the principle of nationality or, more properly, the desire for nationhood and for national existence and development, for self-assertion and for international recognition, the all-important feature of modern times, overshadowing every other phenomenon that historians have to notice, or statesmen to reckon with.
