On observing the visible man with your own eyes what do you try to find in him? The invisible man. These words which your ears catch, those gestures, those airs of the head, his attire and sensible operations of all kinds, are, for you, merely so many expressions; these express something, a soul. An inward man is hidden beneath the outward man, and the latter simply manifests the former. You have observed the house in which he lives, his furniture, his costume, in order to discover his habits and tastes, the degree of his refinement or rusticity, his extravagance or economy, his follies or his cleverness. You have listened to his conversation and noted the inflections of his voice, the attitudes he has assumed, so as to judge of his spirit, self-abandonment or gayety, his energy or his rigidity. You consider his writings, works of art, financial and political schemes, with a view to measure the reach and limits of his intelligence, his creative power and self-command, to ascertain the usual order, kind, and force of his conceptions, in what way he thinks and how he resolves. All these externals are so many avenues converging to one centre, and you follow these only to reach that centre; here is the real man, namely, that group of faculties and of sentiments which produces the rest. Behold a new world, an infinite world; for each visible action involves an infinite train of reasonings and emotions, new or old sensations which have combined to bring this into light and which, like long ledges of rock sunk deep in the earth, have cropped out above the surface and attained their level. It is this subterranean world which forms the second aim, the special object of the historian. If his critical education suffices, he is able to discriminate under every ornament in architecture, under every stroke of the brush in a picture, under each phrase of literary composition, the particular sentiment out of which the ornament, the stroke, and the phrase have sprung; he is a spectator of the inward drama which has developed itself in the breast of the artist or writer; the choice of words, the length or shortness of the period, the species of metaphor, the accent of a verse, the chain of reasoning--all are to him an indication; while his eyes are reading the text his mind and soul are following the steady flow and ever-changing series of emotions and conceptions from which this text has issued; he is working out its psychology. Should you desire to study this operation, regard the promoter and model of all the high culture of the epoch, Goethe, who, before composing his "Iphigenia" spent days in making drawings of the most perfect statues and who, at last, his eyes filled with the noble forms of antique scenery and his mind penetrated by the harmonious beauty of antique life, succeeded in reproducing internally, with such exactness, the habits and yearnings of Greek imagination as to provide us with an almost twin sister of the
