There is, however, a speedy limit to the use of heroes. Every genius is defended from approach by quantities of unavailableness. They are very attractive, and seem at a distance our own; but we are hindered on all sides from approach. The more we are drawn, the more we are repelled. There is something not solid in the good that is done for us. The best discovery the discoverer makes for himself. It has something unreal for his companion, until he too has substantiated it. It seems as if the Deity dressed each soul which he sends into nature in certain virtues and powers not communicable to other men, and, sending it to perform one more turn through the circle of beings, wrote, "_Not transferable_," and "_Good for this trip only_," on these garments of the soul. There is somewhat deceptive about the intercourse of minds. The boundaries are invisible, but they are never crossed. There is such good will to impart, and such good will to receive, that each threatens to become the other; but the law of individuality collects its secret strength: you are you, and I am I, and so we remain. For Nature wishes everything to remain itself; and whilst every individual strives to grow and exclude, and to exclude and grow, to the extremities of the universe, and to impose the law of its being on every other creature, Nature steadily aims to protect each against every other. Each is self-defended. Nothing is more marked than the power by which individuals are guarded from individuals, in a world where every benefactor becomes so easily a malefactor, only by continuation of his activity into places where it is not due; where children seem so much at the mercy of their foolish parents, and where almost all men are too social and interfering. We rightly speak of the guardian angels of children. How superior in their security from infusions of evil persons, from vulgarity and second thought! They shed their own abundant beauty on the objects they behold. Therefore, they are not at the mercy of such poor educators as we adults. If we huff and chide them, they soon come not to mind it, and get a self-reliance; and if we indulge them to folly, they learn the limitation elsewhere.
