That this Conjecture or Opinion of mine, should be detracting from the Dignity of _Moral Virtue_, or have a Tendency to bring it into Disrepute, I can not see. I have already own'd, that it ever was and ever will be preferable to Vice, in the Opinion of all wise Men. But to call Virtue it self Eternal, can not be done without a strangely Figurative Way of Speaking. There is no Doubt, but all Mathematical Truths are Eternal, yet they are taught; and some of them are very abstruse, and the Knowledge of them never was acquir'd without great Labour and Depth of Thought. _Euclid_ had his Merit; and it does not appear that the Doctrine of the _Fluxions_ was known before Sir _Isaac Newton_ discover'd that concise Way of Computation; and it is not impossible that there should be another Method, as yet unknown, still more compendious, that may not be found out these Thousand Years. All Propositions, not confin'd to Time or Place, that are once true, must be always so; even in the silliest and most abject Things in the World; as for Example, It is wrong to under-roast Mutton for People who love to have their Meat well done. The Truth of this, which is the most trifling Thing I can readily think on, is as much Eternal, as that of the Sublimest Virtue. If you ask me, where this Truth was, before there was Mutton, or People to dress or eat it, I answer, in the same Place where Chastity was, before there were any Creatures that had an Appetite to procreate their Species. This puts me in mind of the inconsiderate Zeal of some Men, who even in Metaphysicks, know not how to think abstractly, and cannot forebear mixing their own Meanness and Imbecillities, with the Idea's they form of the Supreme Being.
