We can afford to allow the limitation, if we know it is the meter of the growing man. We can stand against Fate, as children stand up against the wall in their father's house, and notch their height from year to year. But when the boy grows to man, and is master of the house, he pulls down that wall, and builds a new and bigger. 'Tis only a question of time. Every brave youth is in training to ride, and rule this dragon. His science is to make weapons and wings of these passions and retarding forces. Now whether, seeing these two things, fate and power, we are permitted to believe in unity? The bulk of mankind believe in two gods. They are under one dominion here in the house, as friend and parent, in social circles, in letters, in art, in love, in religion: but in mechanics, in dealing with steam and climate, in trade, in politics, they think they come under another; and that it would be a practical blunder to transfer the method and way of working of one sphere into the other. What good, honest, generous men at home, will be wolves and foxes on change! What pious men in the parlor will vote for what reprobates at the polls! To a certain point, they believe themselves the care of a Providence. But in a steamboat, in an epidemic, in war, they believe a malignant energy rules. But relation and connection are not somewhere and sometimes, but everywhere and always. The divine order does not stop where their sight stops. The friendly power works on the same rules, in the next farm and the next planet. But where they have not experience, they run against it, and hurt themselves. Fate, then, is a name for facts not yet passed under the fire of thought--for causes which are unpenetrated. But every jet of chaos which threatens to exterminate us is convertible by intellect into wholesome force. Fate is unpenetrated causes. The water drowns ship and sailor, like a grain of dust. But learn to swim, trim your bark, and the wave which drowned it will be cloven by it, and carry it, like its own foam, a plume and a power. The cold is inconsiderate of persons, tingles your blood, freezes a man like a dew-drop. But learn to skate, and the ice will give you a graceful, sweet, and poetic motion. The cold will brace your limbs and brain to genius, and make you foremost men of time. Cold and sea will train an imperial Saxon race, which nature cannot bear to lose, and, after cooping it up for a thousand years in yonder England, gives a hundred Englands, a hundred Mexicos. All the bloods it shall absorb and domineer: and more than Mexicos--the secrets of water and steam, the spasms of electricity, the ductility of metals, the chariot of the air, the ruddered balloon, are awaiting you.
