The poet alone knows astronomy, chemistry, vegetation, and animation, for he does not stop at these facts, but employs them as signs. He knows why the plain, or meadow of space, was strown with these flowers we call suns, and moons, and stars; why the deep is adorned with animals, with men, and gods; for, in every word he speaks he rides on them as the horses of thought.
Ralph Waldo EmersonThe 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.
Ralph Waldo Emerson
