Can eafily conceive that Men fhould fet up Principles of Logick and Ethicks, both of quando their own making; because our Reafo- fundamen ponebam nings and our Actions, about which thefe Difci-ta terra? plines are converfant, are properly the Work of indica miMan: But I can by no means comprehend, how if babes they fhould dare to advance their own Principles tiam. intelligenof Phyficks, the Object of which is Nature, and Job Nature the Work of God. By what Sagacity xxxvii. fhall we, who have not Skill enough to pene- Numquid trate the Intention of the Creature, be able to tu primus trace out the Defign of the Creator? Was it by ante colles bomo, our Understanding, that he ftretch'd out the formatus? Heavens by our Wisdom, that he laid the Job XV. Foundations of the Earth? Or what Philofo- Sapientiam pher has yet founded the Depths of that eternal Wifdom, which was before all Things, to declare cedentent its Counfels, or fhew us its Secrets?

there's nothing fo certain in Nature, but what Singula may be made the Subject of Difpute. The improvi- Confequence of this, is not that we fhould comtalitatem mence Scepticks, and entertain a general Doubt involvunt, and Diftruft of all Things, but that we fhould ut inter i. not too easily receive the Propofals of those fta certum Authors, who are every Day for building new fit nibil Worlds, and offering new Principles of Phynec mife- ficks; we ought to examine them before we emrius quid. brace them, fhould not fuffer our felves to be furquam bo- priz'd with their Novelty, before we are fatismine, nec fied of their Probability.

almost an abfolute Stranger. Lucretius, however Nam daring and prefumptuous in pronouncing of quamvis rerum ig natural Things, has yet happily confefs'd, that norem prihe was unacquainted with their Originals. We mordiaque may affirm therefore, in general, That the firft fint. 1, 2. Naturalifts advanc'd their Principles only as Con- Quis bojectures; for Nature is too ftately to discover poteft fciher felf to any Beholder. The visible Effects of re confiher Operations may indeed let us into fone lium Dei, Notion of her invifible Powers. But what Eye cogitare quid velit! is ftrong enough to pry into her fecret CounSapien.IX fels, and to pierce thro' the thick Veil of her Defigns? Let us therefore look upon the several Systems, only as fo many probable Explications of what may happen in Nature, not as fo many Laws to neceffitate what muft happen. Let us confider Pythagoras's Numbers, Democritus's Atoms, Leucippus's Plenum and Vacuum, Plato's Ideas, Ariftotle's Matter and Form, Defcartes's Vortices and Corpufcula, only as Notions offer'd to our Scrutiny, not as Rules impos'd upon our Underftanding. Let us hear thofe with the most Favour, who give the most rational Account of all Things; becaufe 'tis plain they have the Art of ranging their Imaginations in the best Order, and with the finest Chain. But let us not fanfie them to have been fo abfurd, as to have given us Opinion for Science, and Probability for Truth. This is a very neceffary Precaution, which we ought to take along with us, if we would tread fecurely in the doubtful and intricate Paths of Nature. For as a falfe Level will drive a whole Building awry, fo a falfe Principle will render a whole Plan of Phyficks irregular and defective.
