Never since man first walked erect have his relations toward nature been so changed, within the same space of time, as they have been since Washington was elected President and the Parisian mob stormed the Bastille. Washington found the task of a readjustment heavy enough, but the civilization he knew was simple. When Washington lived, the fund of energy at man's disposal had not very sensibly augmented since the fall of Rome. In the eighteenth, as in the fourth century, engineers had at command only animal power, and a little wind and water power, to which had been added, at the end of the Middle Ages, a low explosive. There was nothing in the daily life of his age which made the legal and administrative principles which had sufficed for Justinian insufficient for him. Twentieth-century society rests on a basis not different so much in degree, as in kind, from all that has gone before. Through applied science infinite forces have been domesticated, and the action of these infinite forces upon finite minds has been to create a tension, together with a social acceleration and concentration, not only unparalleled, but, apparently, without limit. Meanwhile our laws and institutions have remained, in substance, constant. I doubt if we have developed a single important administrative principle which would be novel to Napoleon, were he to live again, and I am quite sure that we have no legal principle younger than Justinian. As a result, society has been squeezed, as it were, from its rigid eighteenth-century legal shell, and has passed into a fourth dimension of space, where it performs its most important functions beyond the cognizance of the law, which remains in a space of but three dimensions. Washington encountered a somewhat analogous problem when dealing with the thirteen petty independent states, which had escaped from England; but his problem was relatively rudimentary. Taking the theory of sovereignty as it stood, he had only to apply it to communities. It was mainly a question of concentrating a sufficient amount of energy to enforce order in sovereign social units. The whole social detail remained unchanged. Our conditions would seem to imply a very considerable extension and specialization of the principle of sovereignty, together with a commensurate increment of energy, but unfortunately the twentieth-century American problem is still further complicated by the character of the envelope in which this highly volatilized society is theoretically contained. To attain his object, Washington introduced a written organic law, which of all things is the most inflexible. No other modern nation has to consider such an impediment.
