We can ill spare the commanding social benefits of cities; they must be used; yet cautiously, and haughtily,—and will yield their best values to him who best can do without them. Keep the town for occasions, but the habits should be formed to retirement. Solitude, the safeguard of mediocrity, is to genius the stern friend, the cold, obscure shelter where moult the wings which will bear it farther than suns and stars. He who should inspire and lead his race must be defended from travelling with the souls of other men, from living, breathing, reading, and writing in the daily, time-worn yoke of their opinions. "In the morning,—solitude;" said Pythagoras; that Nature may speak to the imagination, as she does never in company, and that her favorite may make acquaintance with those divine strengths which disclose themselves to serious and abstracted thought. ’Tis very certain that Plato, Plotinus, Archimedes, Hermes, Newton, Milton, Wordsworth, did not live in a crowd, but descended into it from time to time as benefactors: and the wise instructor will press this point of securing to the young soul in the disposition of time and the arrangements of living, periods and habits of solitude. The high advantage of university-life is often the mere mechanical one, I may call it, of a separate chamber and fire,—which parents will allow the boy without hesitation at Cambridge, but do not think needful at home. We say solitude, to mark the character of the tone of thought; but if it can be shared between two or more than two, it is happier, and not less noble. "We four," wrote Neander to his sacred friends, "will enjoy at Halle the inward blessedness of a _civitas Dei_, whose foundations are forever friendship. The more I know you, the more I dissatisfy and must dissatisfy all my wonted companions. Their very presence stupefies me. The common understanding withdraws itself from the one centre of all existence."
