She was a phantom of delight When first she gleamed upon my sight, A lovely apparition, sent To be a moment's ornament; Her eyes as stars of twilight fair, Like twilights too her dusky hair, But all things else about her drawn From May-time and the cheerful dawn.
William WordsworthWe 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 Wordsworth
