If once this method were followed with diligence and attention, there is nothing that lyes within the power of human Wit (or which is far more effectual) of human Industry, which we might not compass; we might not only hope for Inventions to equalize those of _Copernicus_, _Galileo_, _Gilbert_, _Harvy_, and of others, whose Names are almost lost, that were the Inventors of _Gun-powder_, the _Seamans Compass_, _Printing_, _Etching_, _Graving_, _Microscopes_, &c. but multitudes that may far exceed them: for even those discoveries seem to have been the products of some such method, though but imperfect; What may not be therefore expected from it if thoroughly prosecuted? _Talking_ and _contention of Arguments_ would soon be turn’d into _labours_; all the fine _dreams_ of Opinions, and _universal metaphysical natures_, which the luxury of subtil Brains has devis’d, would quickly vanish, and give place to _solid Histories_, _Experiments_ and _Works._ And as at first, mankind _fell_ by _tasting_ of the forbidden Tree of Knowledge, so we, their Posterity, may be in part _restor’d_ by the same way, not only by _beholding_ and _contemplating_, but by _tasting_ too those fruits of Natural knowledge, that were never yet forbidden. From hence the World may be assisted with _variety_ of Inventions, _new_ matter for Sciences may be _collected_, the _old improv’d_, and their _rust_ rubb’d away; and as it is by the benefit of Senses that we receive all our Skill in the works of Nature, so they also may be wonderfully benefited by it, and may be guided to an easier and more exact performance of their Offices; ’tis not unlikely, but that we may find out wherein our Senses are deficient, and as easily find wayes of repairing them. The Indeavours of Skilful men have been most conversant about the assistance of the Eye, and many noble Productions have followed upon it; and from hence we may conclude, that there is a way open’d for advancing the operations, not only of all the other Senses, but even of the Eye it self; that which has been already done ought not to content us, but rather to incourage us to proceed further, and to attempt greater things in the same and different wayes. ’Tis not unlikely, but that there may be yet invented several other helps for the eye, at much exceeding those already found, as those do the bare eye, such as by which we may perhaps be able to discover _living Creatures_ in the Moon, or other Planets, the _figures_ of the compounding Particles of matter, and the particular _Schematisms_ and _Textures_ of Bodies.
