5. Of Pores.

AS I have mentioned in my former Discourse, that I do verily believe all or most natural Creatures have some certain kind of respiration, so do I also find it most probable, that all or most natural Creatures have Pores: not empty Pores; for there can be no Vacuum in Nature, but such passages as serve for re∣spiration, which respiration is some kind of receiving and discharging of such matter as is proper to the na∣ture of every Creature: And thus the several Organs of Animal Creatures, are, for the most part, imploy∣ed as great large pores; for Nature being in a perpe∣tual motion, is always dissolving and composing, changing and ordering her self-moving parts as she pleases. But it is well to be observed, that there is difference between Perception and Respiration; for Perception is onely an action of Figuring or Pattern∣ing, when as the Rational and Sensitive Motions do Page  17 figure or pattern out something: but Respiration is an action of drawing, sucking, breathing in, or receiving any ways outward parts, and of venting, discharging, or sending forth inward parts. Next, although there may be Pores in most natural Creatures, by reason that all, or most have some kind of Respiration, yet Nature hath more ways of dividing and uniting of parts, or of ingress and egress, then the way of drawing in, and sending forth by Pores; for Nature is so full of variety, that not any particular corporeal figurative motion can be said the prime or fundamental, unless it be self-motion, the Architect and Creator of all fi∣gures: Wherefore, as the Globular figure is not the prime or fundamental of all other figures, so neither can Respiration be called the prime or fundamental motion; for, as I said, Nature has more ways then one, and there are also retentive Motions in Nature, which are neither dividing nor composing, but keep∣ing or holding together.
