of Philosophy, as to make this Notion attended by a few lesse considerable ones) pass for a New Philosophy itself. Nay, since they boast so much of this phancie of theirs, that the famous Quercetanus scruples not to write, that if his most certain Doctrine of the three Principles were sufficiently Learned, Examin’d, and Cultivated, it would easily Dispel all the Darkness that benights our minds, and bring in a Clear Light, that would remove all Difficulties. This School affording Theorems and Axiomes irrefragable, and to be admitted without Dispute by impartial Judges; and so useful withal, as to exempt us from the necessity of having recourse, for want of the knowledg of causes, to that Sanctuary of the igorant, Occult Qualities; since, I say, this Domestick Notion of the Chymists is so much overvalued by them, I cannot think it unfit, they should be made sensible of their mistake; and be admonish’d to take in more fruitful and comprehensive Principles, if they mean to give us an account of the Phænomena of Nature; and not confine themselves and (as far as they can) others to such narrow Principles, as I fear will scarce inable them to give an account (I mean an intelligible one) of the tenth part (I say not) of all the Phænomena of Nature; but even of all such as by the Leucippian or some of the other sorts of Principles may be plausibly enough explicated. And though I be not unwilling to grant, that the incompetency I impute to the Chymical Hypothesis is but the same which may be Objected against that of the four Elements, and divers other Doctrines that have been maintain’d by Learned men; yet since ’tis the Chymical Hypothesis only which I am now examining, I see not why, if what I impute to it be a real inconvenience, either it should cease to be so, or I should scruple to object it, because either Theories are lyable thereunto, as well as the Hermetical. For I know not why a Truth should be thought lesse a Truth for the being fit to overthrow variety of Errors.
I am oblig’d to You (continues Carneades, a little smiling) for the favourable Opinion You are pleas’d to express of my Equity, if there be no design in it. But I need not be tempted by an Artifice, or invited by a Complement,
