"My little Animal, after you have mentally divided every little Visible Body, into an infinite many little invisible Bodies; you must imagine, That the infinite Universe consists only of these Atomes, which are most solid, most incorruptible, and most simple; whose Figures are partly Cubical, partly Parallelograms, partly Angular, partly Round, partly Sharp-pointed, partly Pyramidal, partly Six-cornered, and partly Oval; which act all severally, according to their Various Figures: And to shew that it is so, put a very round Ivory Bowl upon a very smooth place, and with the least touch you give it will be half a quarter of an hour before it rest: Now I say, that if it were perfectly round, as some of the Atomes I speak of are, and the Surface on which it is put perfectly smooth, it would never rest. If Art then be capable of inclining a Body to a perpetual Motion, why may we not believe that Nature can do it? It's the same with the other Figures, of which the Square requires a perpetual Rest, others an oblique Motion, others a half Motion, as Trepidation; and the Round, whose Nature is to move, joyning a Pyramidal, makes that, perhaps, which we call Fire; because not only Fire is in continual Agitation, but also because it easily penetrates: Besides, the Fire hath different effects, according to the openings and quality of the Angles, when the round Figure is joyned; for Example, The Fire of Pepper is another thing than the Fire of Sugar, the Fire of Sugar differs from that of Cinnamon; that of Cinnamon, from that of the Clove; and this from the Fire of a Faggot. Now the Fire, which is the Architect of the parts and whole of the Universe, hath driven together, and Congregated into an Oak, the quantity of Figures which are necessary for the Composition of that Oak.
