As every wind draws music out of the Æolian harp, so doth every object in Nature draw music out of his mind. Is it not true that every landscape I behold, every friend I meet, every act I perform, every pain I suffer, leaves me a different being from that they found me? That poverty, love, authority, anger, sickness, sorrow, success, all work actively upon our being and unlock for us the concealed faculties of the mind? Whatever private or petty ends are frustrated, this end is always answered. Whatever the man does, or whatever befalls him, opens another chamber in his soul,--that is, he has got a new feeling, a new thought, a new organ. Do we not see how amazingly for this end man is fitted to the world? What leads him to science? Why does he track in the midnight heaven a pure spark, a luminous patch wandering from age to age, but because he acquires thereby a majestic sense of power; learning that in his own constitution he can set the shining maze in order, and finding and carrying their law in his mind, can, as it were, see his simple idea realized up yonder in giddy distances and frightful periods of duration. If Newton come and first of men perceive that not alone certain bodies fall to the ground at a certain rate, but that all bodies in the Universe, the universe of bodies, fall always, and at one rate; that every atom in nature draws to every other atom,--he extends the power of his mind not only over every cubic atom of his native planet, but he reports the condition of millions of worlds which his eye never saw. And what is the charm which every ore, every new plant, every new fact touching winds, clouds, ocean currents, the secrets of chemical composition and decomposition possess for Humboldt? What but that much revolving of similar facts in his mind has shown him that always the mind contains in its transparent chambers the means of classifying the most refractory phenomena, of depriving them of all casual and chaotic aspect, and subordinating them to a bright reason of its own, and so giving to man a sort of property,--yea, the very highest property in every district and particle of the globe. By the permanence of Nature, minds are trained alike, and made intelligible to each other. In our condition are the roots of language and communication, and these instructions we never exhaust. In some sort the end of life is that the man should take up the universe into himself, or out of that quarry leave nothing unrepresented. Yonder mountain must migrate into his mind. Yonder magnificent astronomy he is at last to import, fetching away moon, and planet, solstice, period, comet and binal star, by comprehending their relation and law. Instead of the timid stripling he was, he is to be the stalwart Archimedes, Pythagoras, Columbus, Newton, of the physic, metaphysic and ethics of the design of the world.
