The nature, reach and prescriptive force of this prospective coalescence through neutralisation may perhaps best be appreciated in the light of what has already come to pass, without design or mandatory guidance, in those lines of human interest where the national frontiers interpose no bar, or at least no decisive bar, whether by force of unconcern or through impotence. Fashions of dress, equipage and decorous usage, e.g., run with some uniformity throughout these modern nations, and indeed with some degree of prescriptive force. There is, of course, nothing mandatory, in the simpler sense, about all this; nor is the degree of conformity extreme or uniform throughout. But it is a ready-made generalisation that only those communities are incorporated in this cosmopolitan coalescence of usage that are moved by their own incitement, and only so far as they have an effectually felt need of conformity in these premises. It is true, a dispassionate outsider, if such there be, would perhaps be struck by the degree of such painstaking conformity to canons of conduct which it frequently must cost serious effort even to ascertain in such detail as the case calls for. Doubtless, or at least presumably, conformity under the jurisdiction of the fashions, and in related provinces of decorum, is obligatory in a degree that need not be looked for throughout the scheme of use and wont at large, even under the advisedly established non-interference of the authorities. Still, on a point on which the evidence hitherto is extremely scant it is the part of discretion to hold no settled opinion. A more promising line of suggestion is probably that afforded by the current degree of contact and consistency among the modern nations in respect of science and scholarship, as also in the aesthetic or the industrial arts. Local color and local pride, with one thing and another in the way of special incitement or inhibition, may come in to vary the run of things, or to blur or hinder a common understanding and mutual furtherance and copartnery in these matters of taste and intellect. Yet it is scarcely misleading to speak of the peoples of Christendom as one community in these respects. The sciences and the arts are held as a joint stock among these peoples, in their elements, and measurably also in their working-out. It is true, these interests and achievements of the race are not cultivated with the same assiduity or with identical effect throughout; but it is equally true that no effectual bar could profitably be interposed, or would be tolerated in the long run in this field, where men have had occasion to learn that unlimited collusion is more to the purpose than a clannish discrimination. * * * * *
