Like all our instincts, the instinct of solitude has its especial purpose, which appears to be the protection of rare and delicate natures from the commonplace world around them. Though recluses are considered by men of the world to be doomed to inevitable incompetence, the fact is that many of them have reached the highest distinction in intellectual pursuits. If Shelley had not disliked general society as he did, the originality of his own living and thinking would have been less complete; the influences of mediocre people, who, of course, are always in the majority, would have silently but surely operated to the destruction of that unequalled and personal delicacy of imagination to which we owe what is inimitable in his poetry. In the last year of his life, he said to Trelawny of Mary, his second wife, "She can't bear solitude, nor I society--the quick coupled with the dead." Here is a piteous prayer of his to be delivered from a party that he dreaded: "Mary says she will have a party! There are English singers here, the Sinclairs, and she will ask them, and every one she or you know. Oh the horror! For pity go to Mary and intercede for me! I will submit to any other species of torture than that of being bored to death by idle ladies and gentlemen." Again, he writes to Mary: "My greatest delight would be utterly to desert all human society. I would retire with you and our child to a solitary island in the sea; would build a boat, and shut upon my retreat the flood-gates of the world. I would read no reviews and talk with no authors. If I dared trust my imagination it would tell me that there are one or two chosen companions beside yourself whom I should desire. But to this I would not listen; where two or three are gathered together, the devil is among them." At Marlow he knew little of his neighbors. "I am not wretch enough," he said, "to tolerate an acquaintance." Wordsworth and Turner, if less systematic in their isolation, were still solitary workers, and much of the peculiar force and originality of their performance is due to their independence of the people about them. Painters are especial sufferers from the visits of talkative people who know little or nothing of the art they talk about, and yet who have quite influence enough to disturb the painter's mind by proving to him that his noblest thoughts are surest to be misunderstood. Men of science, too, find solitude favorable to their peculiar work, because it permits the concentration of their powers during long periods of time. Newton had a great repugnance to society, and even to notoriety--a feeling which is different, and in men of genius more rare. No one can doubt, however, that Newton's great intellectual achievements were due in some measure to this peculiarity of his temper, which permitted him to ripen them in the sustained tranquillity necessary to difficult investigations. Auguste Comte isolated himself not only from preference but on system, and whatever
