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 he is 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.
What a man does, that he has. What has he to do with hope or fear? In himself is his might. Let him regard no good as solid but that which is in his nature, and which must grow out of him as long as he exists. The goods of fortune may come and go like summer leaves; let him scatter them on every wind as the momentary signs of his infinite productiveness.
We do not yet trust the unknown powers of thought. Whence came all these tools, inventions, book laws, parties, kingdoms? Out of the invisible world, through a few brains. The arts and institutions of men are created out of thought. The powers that make the capitalist are metaphysical, the force of method and force of will makes trade, and builds towns.
Only by obedience to his genius; only by the freest activity in the way constitutional to him, does an angel seem to arise beforea man, and lead him by the hand out of all the wards of the prison.
Respect the child. Wait and see the new product of Nature. Nature loves analogies, but not repetitions. Respect the child. Be not too much his parent. Trespass not on his solitude.
The axioms of physics translate the laws of ethics. Thus, "the whole is greater than its part;" "reaction is equal to action;" "the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;" and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.
