10. This guiding identity runs through all the surprises and contrasts of the piece, and characterizes every law. Man carries the world in his head, the whole astronomy and chemistry suspended in a thought. Because the history of nature is charactered in his brain, therefore is he the prophet and discoverer of her secrets. Every known fact in natural science was divined by the presentiment of somebody, before it was actually verified. A man does not tie his shoe without recognizing laws which bind the farthest regions of nature: moon, plant, gas, crystal, are concrete geometry and numbers. Common sense knows its own, and recognizes the fact at first sight in chemical experiment. The common sense of Franklin,[510] Dalton,[511] Davy[512] and Black,[513] is the same common sense which made the arrangements which now it discovers.
11. If the identity expresses organized rest, the counter action runs also into organization. The astronomers said,[514] “Give us matter, and a little motion, and we will construct the universe. It is not enough that we should have matter, we must also have a single impulse, one shove to launch the mass, and generate the harmony of the centrifugal and centripetal[515] forces. Once heave the ball from the hand, and we can show how all this mighty order grew.” “A very unreasonable postulate,” said the metaphysicians, “and a plain begging of the question. Could you not prevail to know the genesis of projection, as well as the continuation of it?” Nature, meanwhile, had not waited for the discussion, but, right or wrong, bestowed the impulse, and the balls rolled. It was no great affair, a mere push, but the astronomers were right in making much of it, for there is no end of the consequences of the act. That famous aboriginal push propagates itself through all the balls of the system, and through every atom of every ball, through all the races of creatures, and through the history and performances of every individual. Exaggeration is in the course of things. Nature sends no creature, no man into the world, without adding a small excess of his proper quality. Given the planet, it is still necessary to add the impulse; so, to every creature nature added a little violence of direction in its proper path, a shove to put it on its way; in every instance, a slight generosity, a drop too much. Without electricity the air would rot, and without
