We have no knowledge, that is, no general principles drawn from the contemplation of particular facts, but what has been built up by pleasure, and exists in us by pleasure alone. The Man of Science, the Chemist and Mathematician, whatever difficulties and disgusts they may have had to struggle with, know and feel this. However painful may be the objects with which the Anatomist's knowledge is connected, he feels that his knowledge is pleasure; and where he has no pleasure he has no knowledge.
William WordsworthFor I have learned to look on nature, not as in the hour of thoughtless youth, but hearing oftentimes the still, sad music of humanity.
William WordsworthHappier of happy though I be, like them I cannot take possession of the sky, mount with a thoughtless impulse, and wheel there, one of a mighty multitude whose way and motion is a harmony and dance magnificent.
William Wordsworth
