Bacon is daringly turning this around and announcing that finding out the facts is far more important than theorizing.,Warming up,3 I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me. Sir Isaac Newton, 17th-century English physicist and mathematician, who discovered the laws of gravity,Newton is acclaimed as a great genius who has opened up understanding of nature, but he humbly points out how very little he does actually know especially when compared with all that there is to know.
