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.
Ralph Waldo EmersonIt is much better to learn the elements of geology, of botany, or ornithology and astronomy by word of mouth from a companion than dully from a book.
Ralph Waldo Emerson
