There are numerous Varieties of Figurative Motions in some Creatures; and in others, very few, in comparison: but, the occasion of that, is the manner of the Frame and Form of a Creature: for, some Creatures that are but small, have much more variety of Figurative Motions, than others that are very bigg and large Creatures: so that, it is not only the Quantity of Matter, or Number of Parts, but the several Changes of Motion, by the Variety of their Active Parts, that is the cause of it: for, Nature is not only an Infinite Body, but, being Self-moving, causes Infinite Variety, by the altered Actions of her Parts; every altered Action, causing both an altered Self-knowledg, and an altered Perceptive Knowledg. CHAP. III. Of the Variety of Corporeal Motion, of one and the same sort or kind of Motion. There is Infinite Variety of Motion of the same sorts and kinds of Motions; as for example, Of Dilatations, or Extensions, Expulsions, Attractions, Contractions, Retentions, Digestions, Respirations: There is also Varieties of Densities, Rarities, Gravities, Levities, Measures, Sizes, Agilness, Slowness, Strength, Weakness, Times, Seasons, Growths, Decays, Lives, Deaths, Conceptions, Perceptions, Passions, Appetites, Sympathies, Antipathies, and Millions the like kinds, or sorts. CHAP. IV. Of the Variety of particular Creatures. Nature is so delighted with _Variety_, that seldom two Creatures (although of the same sort, nay, from the same Producers) are just alike; and yet Human Perception cannot perceive above four kinds of Creatures, viz. _Animals, Vegetables, Minerals_, and _Elements_: but, the several sorts seem to be very numerous; and the Varieties of the several Particulars, Infinite: but, Nature is necessitated to divide her Creatures into Kinds and Sorts, to keep Order and Method: for, there may be numerous Varieties of sorts; as for example, Many several Worlds, and infinite Varieties of Particulars in those _Worlds_: for, Worlds may differ from each other, as much as several sorts of Animals, Vegetables, Minerals, or Elements; and yet be all of that sort we name Worlds: but, as for the Infinite Varieties of Nature, we may say, That every Part of Nature is Infinite, in some sort; because every Part of Nature is a perpetual Motion, and makes Infinite Varieties, by change or alteration of Action: but, there is so much Variety of the several Shapes, Figures, Forms, and Sizes, as, Bigger, and Less; as also, several sorts of Heats, Colds, Droughts, Moistures, Fires, Airs, Waters, Earths, Animals, Vegetables, and Minerals, as are not to be expressed. CHAP. V. Of Dividing, and Rejoyning, or Altering Exterior Figurative Motions.
