Last of all, as I do not beleeve my selfe to be deceiv'd in that which make up the grosse and main of the designe, so I do not expect that all that I shall advance in the sequel upon this connexion of the Languages, should be receiv'd by all for uncontrouleable truths, of which I my selfe am sufficiently perswaded; I am too well acquainted with the nature of truth to beleeve my selfe so succesfull as to have alwayes uncover'd that in the most imbroyld and the most doubtfull affaires of the world; yet I confesse that notwithstanding that great respect that is due to it, I have in some cases lesse regarded it when it did not appear to comply with the capacityes of ordinary men, persuading my selfe that conjecture well fram'd and adjusted by a plausible Air is more rellishing to ingenious persons, then an obscure and fainting truth, of which sort there is a very great number in the present subject. I propose then to the Learned, this new systeme of the Languages, not as an incontestable Thesis in all its parts but only as an Hypothesis, not altogether irrationall and which besides hath this particular advantage, that although it should be the falsest thing in the world in speculation, it may at least be allowable in the practice, And I hope to receive the same favour that persons (that were most obstinately resolv'd against his Hypothesis) granted Copernicus by their confession, that let it be never so false it is however the best accommodated to use and Astronomicall supputations.
