When I say,[13] A little head may be full, and a great head may be empty of rational matter, I mean there may be as it were an ebbing or flowing, that is more or less of Rational Matter joyned with the Sensitive and Inanimate: And when I say, That, if all the heads of Mankind were put into one, and sufficient quantity of Rational Matter therein, that Creature would not onely have the knowledge of every particular, but that Understanding and Knowledge would increase like Use-money, my meaning is, that if there were much of those parts of rational matter joyned, they would make more variety by self-change of corporeal motions.
When I name Humane sense and reason, I mean such sensitive and rational perception and knowledge as is proper to the nature of Man; and when I say Animal sense and reason, I mean such as is proper to the nature of all Animals; for I do not mean that the sensitive and rational corporeal motions which do make a man, or any Animal, are bound to such figures eternally, but whilest they work and move in such or such figures, they make such perceptions as belong to the nature of those figures; but when those self-moving parts dissolve the figure of an Animal into a Vegetable or any other Creature, then they work according to the nature of that same figure, both exteriously and interiously.
When I say,[14] That Place, Space, Measure, Number, Weight, Figures, &c. are mixed with Substance, I do not mean they are incorporeal, and do inhere in substance as so many incorporeal modes or accidents; but my meaning is, they are all corporeal parts and actions of Nature, there being no such thing in Nature that may be called incorporeal; for Place, Figure, Weight, Measure, &c. are nothing without Body, but Place and Body are but one thing, and so of the rest. Also when I say,[15] That sometimes Place, sometimes Time, and sometimes Number gives advantage, I mean, that several parts of Matter are getting or losing advantage.
When I say,[16] an Animal or any thing else that has exterior local motion, goeth or moveth to such or such a place, I mean, to such or such a body; and when such a Creature doth not move out of its place, I mean, it doth not remove its body from such or such parts adjoyning to it.
When I say,[17] The rational animate matter divides it self into as many parts, and after as many several manners as their place or quantity will give way to, I mean their own place and quantity: also, as other parts will give way to those parts, for some parts will assist others, and some do obstruct others.
When I say,[18] That the Nature of extension or dilation strives or endeavours to get space, ground, or compass, I mean those corporeal motions endeavour to make place and space by their extensions, that is, to spread their parts of matter into a larger compass or body. And when I say, That Contractions endeavour to cast or thrust out space, place, ground, or compass, My meaning is, That those corporeal motions endeavour to draw their parts of matter into a more close and solid body, for there is no place nor space without body.
Also when I name[19] several tempered substances and matters, I mean several changes and mixtures of corporeal motions.
Also when I speak of Increase and Decrease, I mean onely an alteration of corporeal figurative motions, as uniting parts with parts, and dissolving or separating parts from parts.
When I say,[20] That the motions of cold, and the motions of moisture, when they meet, make cold and moist effects, and when the motions of heat and moisture meet, make hot and moist effects; and so for the motions of cold and dryness: I mean, that when several parts do joyn in such several corporeal motions, they cause such effects; and when I say cold and heat presses into every particular Creature, I mean, that every Creatures natural and inherent perceptive motions make such patterns as their exterior objects are, viz. hot or cold, if they do but move regularly, for if they be irregular, then they do not: as for example; those in an Ague will shake for cold in a hot Summers day, and those that are in a Fever will burn with heat, although they were at the Poles.
When I say,[21] that hot motions, and burning motions, and hot figures, and burning figures do not associate or joyn together in all Creatures: I mean, that the corporeal motions in some figures or creatures, do act in a hot, but not in a burning manner; and when I say, some creatures have both hot and burning motions and figures, I mean, the corporeal motions act both in a hot and burning manner; for though heat is in a degree to burning, yet it is not always burning, for burning is the highest degree of heat, as wetness is the highest degree of moisture.
