Such philosophy as shall not vanish in the fume of subtile, sublime, or delectable speculation but shall be operative to the endowment and betterment of man's life.
Suspicions that the mind, of itself, gathers, are but buzzes; but suspicions that are artificially nourished and put into men's heads by the tales and whisperings of others, have stings.
If I go to the National Gallery and I look at one of the great paintings that excite me there, it's not so much the painting that excites me as that the painting unlocks all kinds of valves of sensation within me which return me to life more violently.
He that seeketh to be eminent amongst able men hath a great task; but that is ever good for the public. But he that plots to be the only figure amongst ciphers is the decay of a whole age.
Another 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.
Moreover, the works already known are due to chance and experiment rather than to sciences; for the sciences we now possess are merely systems for the nice ordering and setting forth of things already invented; not methods of invention or directions for new works.
