There is not any Creature in Nature, that is not composed of Self-moving Parts, (_viz._ both of Rational and Sensitive) as also of the Inanimate Parts, which are Self-knowing: so that all Creatures, being composed of these sorts of Parts, must have a Sensitive, and Rational Knowledg and Perception, as Animals, Vegetables, Minerals, Elements, or what else there is in Nature: But several kinds, and several sorts in these kinds of Creatures, being composed after different manners, and ways, must needs have different Lives, Knowledges, and Perceptions: and not only every several kind, and sort, have such differences; but, every particular Creature, through the variations of their Self-moving Parts, have varieties of Lives, Knowledges, Perceptions, Conceptions, and the like; and not only so, but every particular part of one and the same Creature, have varieties of Knowledges, and Perceptions, because they have varieties of Actions. But, (as I have declared) there is not any different kind of Creature, that can have the like Life, Knowledg, and Perception; not only because they have different Productions, and different Forms; but, different Natures, as being of different kinds. CHAP. III. Of Perception of Parts, and United Perception. All the Self-moving Parts are perceptive; and, all Perception is in Parts, and is dividable, and compoundable, as being Material; also, Alterable, as being Self-moving: Wherefore, no Creature that is composed, or consists of many several sorts of Corporeal Figurative Motions, but must have many sorts of Perception; which is the reason that one Creature, as Man, cannot perceive another Man any otherwise but in Parts: for, the Rational, and Sensitive; nay, all the Parts of one and the same Creature, perceive their Adjoining Parts, as they perceive Foreign Parts; only, by their close conjunction and near relation, they unite in one and the same actions. I do not say, they always agree: for, when they move irregularly, they disagree: And some of those United Parts, will move after one manner, and some after another; but, when they move regularly, then they move to one and the same Design, or one and the same United Action. So, although a Creature is composed of several sorts of Corporeal Motions; yet, these several sorts, being properly united in one Creature, move all agreeably to the Property and Nature of the whole Creature; that is, the particular Parts move according to the property of the whole Creature; because the particular Parts, by conjunction, make the Whole: So that, the several Parts make one Whole; by which, a Whole Creature hath both a general Knowledg, and a Knowledg of Parts; whereas, the Perceptions of Foreign Objects, are but in the Parts: and this is the reason why one Creature perceives not the Whole of another Creature, but only some Parts. Yet this is to be noted, That not any Part hath another Part's Nature, or Motion, nor therefore, their Knowledg, or Perception; but,
