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 EmersonDo not spill thy soul in running hither and yon, grieving over the mistakes and the vices of others. The one person whom it is most necessary to reform is yourself.
Ralph Waldo Emerson
