Double standards are inspiration to men of letters, but they are apt to be fatal to politicians. Adams had no reason to care whether his standards were popular or not, and no one else cared more than he; but Roosevelt and Lodge were playing a game in which they were always liable to find the shifty sands of American opinion yield suddenly under their feet. With this game an elderly friend had long before carried acquaintance as far as he wished. There was nothing in it for him but the amusement of the pugilist or acrobat. The larger study was lost in the division of interests and the ambitions of fifth-rate men; but foreign affairs dealt only with large units, and made personal relation possible with Hay which could not be maintained with Roosevelt or Lodge. As an affair of pure education the point is worth notice from young men who are drawn into politics. The work of domestic progress is done by masses of mechanical power -- steam, electric, furnace, or other -- which have to be controlled by a score or two of individuals who have shown capacity to manage it. The work of internal government has become the task of controlling these men, who are socially as remote as heathen gods, alone worth knowing, but never known, and who could tell nothing of political value if one skinned them alive. Most of them have nothing to tell, but are forces as dumb as their dynamos, absorbed in the development or economy of power. They are trustees for the public, and whenever society assumes the property, it must confer on them that title; but the power will remain as before, whoever manages it, and will then control society without appeal, as it controls its stokers and pit-men.
Modern politics is, at bottom, a struggle not of men but of forces. The men become every year more and more creatures of force, massed about central power-houses. The conflict is no longer between the men, but between the motors that drive the men, and the men tend to succumb to their own motive forces.
This is a moral that man strongly objects to admit, especially in mediæval pursuits like politics and poetry, nor is it worth while for a teacher to insist upon it. What he insists upon is only that in domestic politics, every one works for an immediate object, commonly for some private job, and invariably in a near horizon, while in foreign affairs the outlook is far ahead, over a field as wide as the world. There the merest scholar could see what he was doing. For history, international relations are the only sure standards of movement; the only foundation for a map. For this reason, Adams had always insisted that international relation was the only sure base for a chart of history.
He cared little to convince any one of the correctness of his view, but as teacher he was bound to explain it, and as friend he found it convenient.
The Secretary of State has always stood as much alone as the historian.
Required to look far ahead and round hm, he measures forces unknown to party managers, and has found Congress more or less hostile ever since Congress first sat. The Secretary of State exists only to recognize the existence of a world which Congress would rather ignore; of obligations which Congress repudiates whenever it can; of bargains which Congress distrusts and tries to turn to its advantage or to reject. Since the first day the Senate existed, it has always intrigued against the Secretary of State whenever the Secretary has been obliged to extend his functions beyond the appointment of Consuls in Senators' service.
This is a matter of history which any one may approve or dispute as he will; but as education it gave new resources to an old scholar, for it made of Hay the best schoolmaster since 1865. Hay had become the most imposing figure ever known in the office. He had an influence that no other Secretary of State ever possessed, as he had a nation behind him such as history had never imagined. He needed to write no state papers; he wanted no help, and he stood far above counsel or advice; but he could instruct an attentive scholar as no other teacher in the world could do; and Adams sought only instruction -- wanted only to chart the international channel for fifty years to come; to triangulate the future; to obtain his dimension, and fix the acceleration of movement in politics since the year 1200, as he was trying to fix it in philosophy and physics; in finance and force.
