schoolmen had used the method; it is natural to the human mind. The Stagirite was the founder of a school, Bacon the teacher and populariser for a nation. Aristotle’s Greek was known to few, Bacon’s eloquent English opened out the subject to the many whom he impregnated with his own confidence in the grand progressiveness of human thought. Lewes says: “The spirit of his philosophy was antagonistic to theology, for it was a spirit of doubt and search; and its search was for visible and tangible results.” Bacon himself, in his essay on Superstition, says: “Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation, all which may be guides to an outward moral virtue, though religion were not; but superstition dismounts all these, and erecteth an absolute monarchy in the minds of men: therefore Atheism did never perturb states; for it makes men wary of themselves, as looking no further; and we see the times inclined to Atheism, as the time of Augustus Caesar, were civil times; but superstition hath been the confusion of many states, and bringeth in a new _primum mobile_ (the first motive cause), that ravisheth all the spheres of government.” It is true that he also wrote against Atheism, and this in strong language, but his philosophy was not used for the purpose of proving theological propositions. He said: “True philosophy is that which is the faithful echo of the voice of the world, which is written in some sort under the dictation of things, which adds nothing of itself, which is only the rebound, the reflexion of reality.” It has been well said that the words “Utility and Progress” give the keynotes of Bacon’s teachings. With one other extract we leave his writings. “Crafty men,” he says, “contemn studies, simple men admire them, and wise men use them; for they teach not their own use; but that is a wisdom without them, and above them, won by observation. Read not to contradict and confute, nor to believe and take for granted, nor to find talk and discourse; but to weigh and consider. Some books are to be tasted, others to be swallowed, and some few to be chewed and digested. Reading maketh a full man; conference a ready man; and writing an exact man; and therefore, if a man write little, he need have a great memory; if he confer little, he need have a present wit; and if he read little, he had need have much cunning, to seem to know that he doth not. Histories make men wise; poets witty; the mathematicis subtle; natural philosophy deep; moral, grave; logic and rhetoric, able to contend.” He was the father of experimental philosophy. In one of his suggestions as to the force of attraction of gravitation may be found the first aid to Sir Isaac Newton’s later demonstrations on this head; another of his suggestions, worked out by Torricelli, ended in demonstrating the weight of the atmosphere. But to the method he so popularised may be attributed the grandest discoveries of modern times.
