I answer: That if all the Rational and Sensitive Parts of Nature, are Perceptive, and that no part is without Perception; then all Artificial Productions are Perceptive. CHAP. XIII. Of several Kinds and Sorts of Species. According to my Opinion, though the _Species_ of this World, and all the several Kinds and Sorts of _Species_ in this World, do always continue; yet, the particular Parts of one and the same Kind or sort of _Species_, do not continue: for, the particular Parts are perpetually altering their Figurative Actions. But, by reason some Parts compose or unite, as well as some Parts dissolve or disunite; all kinds and sorts of _Species_, will, and must last so long as Nature lasts. But mistake me not, I mean such kinds and sorts of _Species_ as we name Natural, that is, the Fundamental Species; but not such _Species_, as we name Artificial. CHAP. XIV. Of Different WORLDS. Tis probable if Nature be Infinite, there are several kinds and sorts of those Species, Societies, or Creatures, we name _Worlds_; which may be so different from the Frame, Form, Species, and Properties of this World, and the Creatures of this World, as not to be any ways like this World, or the Creatures in this World. But mistake me not, I do not mean, not like this World, as it is Material and Self-moving; but, not of the same Species, or Properties: as for example, That they have not such kind of Creatures, or their Properties, as Light, Darkness, Heat, Cold, Dry, Wet, Soft, Hard, Leight, Heavy, and the like. But some may say, _That is impossible: for, there can be no World, but must be either Light or Dark, Hot or Cold, Dry or Wet, Soft or Hard, Heavy or Leight; and the like_.
