It is idle to expect any great advancement in science from the superinducing and engrafting of new things upon old. We must begin anew from the very foundations, unless we would revolve for ever in a circle with mean and contemptible progress.
It is by discourse that men associate, and words are imposed according to the apprehension of the vulgar. And therefore the ill and unfit choice of words wonderfully obsesses the understanding. Nor do the definitions or explanations wherewith in some things learned men are wont to guard and defend themselves, by any means set the matter right. But words plainly force and overrule the understanding, and throw all into confusion, and lead men away into innumerable and inane controversies and fancies.
For first of all we must prepare a Natural and Experimental History, sufficient and good; and this is the foundation of all; for we are not to imagine or suppose, but to discover, what nature does or may be made to do.
I had rather believe all the Fables in the Legend, and the Talmud, and the Alcoran, then that this universall Frame, is without a Minde. And therefore, God never wrought Miracle, to convince Atheisme, because his Ordinary Works Convince it. It is true, that a little Philosophy inclineth Mans Minde to Atheisme; But depth in Philosophy, bringeth Mens Mindes about to Religion.
There is in man's nature a secret inclination and motion towards love of others, which, if it be not spent upon some one or a few, doth naturally spread itself towards many, and maketh men become humane and charitable, as it is seen sometimes in friars. Nuptial love maketh mankind, friendly love perfecteth it, but wanton love corrupteth and embaseth it.
Again men have been kept back as by a kind of enchantment from progress in science by reverence for antiquity, by the authority of men counted great in philosophy, and then by general consent.
