It would be unsound fancy and self-contradictory to expect that things which have never yet been done can be done except by means which have never yet been tried.
Francis BaconAnother argument of hope may be drawn from this-that some of the inventions already known are such as before they were discovered it could hardly have entered any man's head to think of; they would have been simply set aside as impossible. For in conjecturing what may be men set before them the example of what has been, and divine of the new with an imagination preoccupied and colored by the old; which way of forming opinions is very fallacious, for streams that are drawn from the springheads of nature do not always run in the old channels.
Francis BaconNothing doth so much keep men out of the Church, and drive men out of the Church, as breach of unity.
Francis Bacon
