Science is facts; just as houses are made of stone, so is science made of facts; but a pile of stones is not a house, and a collection of facts is not necessarily science. - Jules Henri Poincaré (1854-1912) French mathematician.
Science is nothing but trained and organized common sense differing from the latter only as a veteran may differ from a raw recruit: and its methods differ from those of common sense only as far as the guardsman's cut and thrust differ from the manner in which a savage wields his club. - Thomas Henry Huxley (1825-95) English biologist. "The Method of Zadig" in Collected Essays IV.
