Unity and Uniformity were the whole motive of philosophy, and if Darwin, like a true Englishman, preferred to back into it — to reach God a posterior… - Henry Adams

One could divine pretty nearly where the force lay, since the last ten years had given to the great mechanical energies — coal, iron, steam — a distinct superiority in power over the old industrial elements — agriculture, handwork, and learning; but the result of this revolution on a survivor from the fifties resembled the action of the earthworm; he twisted about, in vain, to recover his starting-point; he could no longer see his own trail; he had become an estray; a flotsam or jetsam of wreckage; a belated reveller, or a scholar-gipsy like Matthew Arnold's. His world was dead. Not a Polish Jew fresh from Warsaw or Cracow — not a furtive Yacoob or Ysaac still reeking of the Ghetto, snarling a weird Yiddish to the officers of the customs — but had a keener instinct, an intenser energy, and a freer hand than he — American of Americans, with Heaven knew how many Puritans and Patriots behind him, and an education that had cost a civil war.

It is in dealing with administration, as I apprehend, that civilizations have usually, though not always, broken down, for it has been on administrative difficulties that revolutions have for the most part supervened. Advances in administration seem to presuppose the evolution of new governing classes, since apparently, no established type of mind can adapt itself to changes in environment even in slow-moving civilizations, as fast as environments change. Administration is the capacity of coordinating many, and often conflicting, social energies in a single organism, so adroitly that they shall operate as a unity. This presupposes the power of recognizing a series of relations between numerous special social interests, with all of which no single man can be intimately acquainted. Probably no very highly specialized class can be strong in this intellectual quality because of the intellectual isolation incident to specialization; and yet administration or generalization is not only the faculty upon which social stability rests, but is possibly the highest faculty of the human mind.

Like so many other great observers, Langley was not a mathematician, and like most physicists, he believed in physics. Rigidly denying himself the amusement of philosophy, which consists chiefly in suggesting unintelligible answers to insoluble problems, he still knew the problems, and liked to wander past them in a courteous temper, even bowing to them distantly as though recognising their existence though doubting their respectability.
