Out upon nature, in upon himself, back through the mists that shroud the past, forward into the darkness that overhangs the future, turns the restless desire that arises when the animal wants slumber in satisfaction. Beneath things, he seeks the law; he would know how the globe was forged and the stars were hung, and trace to their origins the springs of life. And, then, as the man develops his nobler nature, there arises the desire higher yet—the passion of passions, the hope of hopes—the desire that he, even he, may somehow aid in making life better and brighter, in destroying want and sin, sorrow and shame. He masters and curbs the animal; he turns his back upon the feast and renounces the place of power; he leaves it to others to accumulate wealth, to gratify pleasant tastes, to bask themselves in the warm sunshine of the brief day. He works for those he never saw and never can see; for a fame, or maybe but for a scant justice, that can only come long after the clods have rattled upon his coffin lid. He toils in the advance, where it is cold, and there is little cheer from men, and the stones are sharp and the brambles thick. Amid the scoffs of the present and the sneers that stab like knives, he builds for the future; he cuts the trail that progressive humanity may hereafter broaden into a highroad. Into higher, grander spheres desire mounts and beckons, and a star that rises in the east leads him on. Lo! the pulses of the man throb with the yearnings of the god—he would aid in the process of the suns! Is not the gulf too wide for the analogy to span? Give more food, open fuller conditions of life, and the vegetable or animal can but multiply; the man will develop. In the one the expansive force can but extend existence in new numbers; in the other, it will inevitably tend to extend existence in higher forms and wider powers. Man is an animal; but he is an animal plus something else. He is the mythic earth-tree, whose roots are in the ground, but whose topmost branches may blossom in the heavens!
