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.
