The Self-moving Parts, or Corporeal Motions, are the Producers of all Composed Figures, such as we name _Creatures_: for, though all Matter hath Figure, by being Matter; for it were non-sense to say, _Figureless Matter_; since the most pure Parts of Matter, have Figure, as well as the grossest; the rarest, as well as the densed: But, such Composed Figures which we name _Creatures_, are produced by particular Associations of Self-moving Parts, into particular kinds, and sorts; and particular Creatures in every kind, or sort. The particular kinds, that are subject to Human Perceptions, are those we name Animals, Vegetables, Minerals, and Elements; of which kinds, there are numerous sorts; and of every sort, infinite particulars: And though there be Infinite Varieties in Nature, made by the Corporeal Motions, or Self-moving Parts, which might cause a Confusion: Yet, considering Nature is intire in her self, as being only Material, and as being but one United Body; also, poysing all her Actions by Opposites; 'tis impossible to be any ways in Extreams, or to have a Confusion. CHAP. II. Of Productions in general. The Sensitive Self-moving Parts, or Corporeal Motions, are the Labouring Parts of all Productions, or Fabricks of all Creatures; but yet, those Corporeal Motions, are parts of the Creature they produce: for, Production is only a Society of particular Parts, that joyn into particular Figures, or Creatures: but, as Parts produce Figures, by Association; so they dissolve those Figures by Division: for, Matter is a perpetual Motion, that is always dividing and composing; so that not any Creature can be eternally one and the same: for, if there were no Dissolvings, and Alterings, there would be no varieties of Particulars; for, though the kinds and sorts may last, yet not the Particulars. But, mistake me not, I do not say those Figures are lost, or annihilated in Nature; but only, their Society is dissolved, or divided in Nature. But this is to be noted, That some Creatures are sooner produced and perfected, than others; and again, some Creatures are sooner decayed, or dissolved. CHAP. III. Of Productions in general.
