The Sceptical Chymist | Page 8

pause, during which he turn'd himself to Eleutherius and me) he did in this manner.
Notwithstanding the subtile reasonings I have met with in the books of the Peripateticks, and the pretty experiments that have been shew'd me in the Laboratories of Chymists, I am of so diffident, or dull a Nature, as to think that if neither of them can bring more cogent arguments to evince the truth of their assertion then are wont to be brought; a Man may rationally enough retain some doubts concerning the very number of those materiall Ingredients of mixt bodies, which some would have us call Elements, and others principles. Indeed when I considered that the Tenents concerning the Elements are as considerable amongst the Doctrines of natural Philosophy as the Elements themselves are among the bodies of the Universe, I expected to find those Opinions solidly establish'd, upon which so many others are superstructed. But when I took the pains impartially to examine the bodies themselves that are said to result from the blended Elements, and to torture them into a confession of their constituent Principles, I was quickly induc'd to think that the number of the Elements has been contended about by Philosophers with more earnestness then success. This unsatisfiedness of mine has been much wonder'd at, by these two Gentlemen (at which words he pointed at Themistius and Philoponus) who though they differ almost as much betwixt themselves about the question we are to consider, as I do from either of them, yet they both agree very well in this, that there is a determinate number of such ingredients as I was just now speaking of, and that what that number is, I say not, may be, (for what may not such as they perswade?) but is wont to be clearly enough demonstrated both by Reason and Experience. This has occasion'd our present Conference. For our Discourse this afternoon, having fallen from one subject to another, and at length setl'd on this, they proffer'd to demonstrate to me, each of them the truth of his opinion, out of both the Topicks that I have freshly nam'd. But on the former (that of Reason strictly so taken) we declin'd insisting at the present, lest we should not have time enough before supper to go thorough the Reasons and Experiments too. The latter of which we unanimously thought the most requisite to be seriously examin'd. I must desire you then to take notice Gentlemen (continued Carneades) that my present business doth not oblige me so to declare my own opinion on the Subject in question, as to assert or deny the truth either of the Peripatetick, or the Chymical Doctrine concerning the number of the Elements, but only to shew you that neither of these Doctrines hath been satisfactorily proved by the arguments commonly alledged on its behalfe. So that if I really discern (as perhaps I think I do) that there may be a more rational account then ordinary, given of one of these opinions, I am left free to declare my self of it, notwithstanding my present engagement, it being obvious to all your observation, that a solid truth may be generally maintained by no other, then incompetent Arguments. And to this Declaration I hope it will be needless to add, that my task obliges me not to answer the Arguments that may be drawn either for Themistius or Philoponus's Opinion from the Topick of reason, as opposed to experiments; since 'tis these only that I am to examine and not all these neither, but such of them alone as either of them shall think fit to insist on, and as have hitherto been wont to be brought either to prove that 'tis the four Peripatetick Elements, or that 'tis the three Chymical Principles that all compounded bodies consist of. These things (adds Carneades) I thought my self obliged to premise, partly lest you should do these Gentlemen (pointing at Themistius and Philoponus, and smiling on them) the injury of measuring their parts by the arguments they are ready to propose, the lawes of our Conference confining them to make use of those that the vulgar of Philosophers (for even of them there is a vulgar) has drawn up to their hands; and partly, that you should not condemn me of presumption for disputing against persons over whom I can hope for no advantage, that I must not derive from the nature, or rules of our controversy, wherein I have but a negative to defend, and wherein too I am like on several occasions to have the Assistance of one of my disagreeing adversaries against the other.
Philoponus and Themistius soon returned this complement with civilities of the like nature, in which Eleutherius perceiving them engaged, to prevent the further loss of
