For, I should tell you that I have sometimes thought it not unfit, that to the Principles which may be assign'd to things, as the World is now Constituted, we should, if we consider the Great Mass of matter as it was whilst the Universe was in making, add another, which may Conveniently enough be call'd an Architectonick Principle or power; by which I mean those Various Determinations, and that Skilfull Guidance of the motions of the small parts of the Universal matter by the most wise Author of things, which were necessary at the beginning to turn that confus'd _Chaos_ into this Orderly and beautifull World; and Especially, to contrive the Bodies of Animals and Plants, and the Seeds of those things whose kinds were to be propagated. For I confess I cannot well Conceive, how from matter, Barely put into Motion, and then left to it self, there could Emerge such Curious Fabricks as the Bodies of men and perfect Animals, and such yet more admirably Contriv'd parcels of matter, as the seeds of living Creatures. I should likewise tell you upon what grounds, and in what sence, I suspected the Principles of the World, as it now is, to be Three, _Matter_, _Motion_ and _Rest_. I say, _as the World now is_, because the present Fabrick of the Universe, and especially the seeds of things, together with the establisht Course of Nature, is a Requisite or Condition, upon whose account divers things may be made out by our three Principles, which otherwise would be very hard, if possible, to explicate. I should moreover declare in general (for I pretend not to be able to do it otherwise) not only why I Conceive that Colours, Odors, Tasts, Fluidness and Solidity, and those other qualities that Diversifie and Denominate Bodies may Intelligibly be Deduced from these three; _but how two of the Three_ Epicurean Principles (which, I need not tell, you [Transcriber's Note: tell you,] are Magnitude, Figure and Weight) are Themselves Deducible from Matter and Motion; since the Latter of these Variously Agitating, and, as it were, Distracting the Former, must needs disjoyne its parts; which being Actually separated must Each of them necessarily both be of some Size, and obtain some shape or other. Nor did I add to our Principles the _Aristotelean Privation_, partly for other Reasons, which I must not now stay to insist on; and partly because it seems to be rather an Antecedent, or a _Terminus a quo_, then a True Principle, as the starting-Post is none of the Horses Legs or Limbs.
