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.
There is much in nature against us. But we forget:
Take nature altogether since time began,
Including human nature, in peace and war,
And it must be a little more in favor of man.
Mid-summer ... when the alchemy of Nature transmutes the sylvan landscape to one vivid and almost homogeneous mass of green; when the senses are well-nigh intoxicated with the surging seas of moist verdure and the subtly indefinable odours of the soil and the vegetation. In such surroundings the mind loses its perspective; time and space become trivial and unreal, and echoes of a forgotten prehistoric past beat insistently upon the enthralled consciousness.
Nature shows us only the tail of the lion. But there is no doubt in my mind that the lion belongs with it even if he cannot reveal himself to the eye all at once because of his huge dimension.
Nature is one with rapine, a harm no preacher can heal; The Mayfly is torn by the swallow, the sparrow speared by the shrike, And the whole little wood where I sit is a world of plunder and prey.
When the last tree is cut, the last fish is caught, and the last river is polluted; when to breathe the air is sickening, you will realize, too late, that wealth is not in bank accounts and that you can't eat money.
From the oyster to the eagle, from the swine to the tiger, all animals are to be found in men and each of them exists in some man, sometimes several at the time. Animals are nothing but the portrayal of our virtues and vices made manifest to our eyes, the visible reflections of our souls. God displays them to us to give us food for thought.
Nature is a language and every new fact one learns is a new word; but it is not a language taken to pieces and dead in the dictionary, but the language put together into a most significant and universal sense. I wish to learn this language - not that I may know a new grammar, but that I may read the great book which is written in that tongue.
This revelation of the secrets of nature, long mercifully withheld from man, should arouse the most solemn reflections in the mind and conscience of every human being capable of comprehension. We must indeed pray that these awful agencies will be made to conduce to peace among the nations, and that instead of wreaking measureless havoc upon the entire globe, may become a perennial fountain of world prosperity.
To be sure, it is not the fruits of scientific research that elevate a man and enrich his nature, but the urge to understand, the intellectual work, creative or receptive.
The glory of the farmer is that, in the division of labors, it is his part to create. All trade rests at last on his primitive activity. He stands close to Nature; he obtains from the earth the bread and the meat. The food which was not, he causes to be.
The use of natural history is to give us aid in supernatural history: the use of the outer creation, to give us language for the beings and changes of the inward creation.
