"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."
