To Bacon was given the honor of having distinguished between the fantasies of old wives' tales and the certainty of empiricism. Moved by the ghost of Bacon, the Royal Society had for its purpose, according to Hooke, "To improve the knowledge of naturall things, and all useful Arts, Manufactures, Mechanick practises, Engynes and Inventions by Experiments."[i-3] The zeal for experiment was equaled only by its miscellaneousness. Cheese making, the eclipses of comets, and the intestines of gnats were alike the objects of telescopic or microscopic scrutiny. The full implication of Baconian empiricism came to fruition in Newton, who in 1672 was elected a Fellow of the Royal Society. Bacon was not the least of those giants upon whose shoulders Newton stood. To the experimental tradition of Kepler, Brahe, Harvey, Copernicus, Galileo, and Bacon, Newton joined the mathematical genius of Descartes; and as a result became "as thoroughgoing an empiricist as he was a consummate mathematician," for whom there was "no _a priori_ certainty."[i-4] At this time it is enough to note of Newtonianism, that for the incomparable physicist "science was composed of laws stating the mathematical behaviour of nature solely--laws clearly deducible from phenomena and exactly verifiable in phenomena--everything further is to be swept out of science, which thus becomes a body of absolutely certain truth about the doings of the physical world."[i-5] The pattern of ideas known as Newtonianism may be summarized as embracing a belief in (1) a universe governed by immutable natural laws, (2) which laws constitute a sublimely harmonious system, (3) reflecting a benevolent and all-wise Geometrician; (4) thus man desires to effect a correspondingly harmonious inner heaven; (5) and feels assured of the plausibility of an immortal life. Newton was a believer in scriptural revelation. It is ironical that through his cosmological system, mathematically demonstrable, he lent reinforcement to deism, the most destructive intellectual solvent of the authority of the altar.
