§. 4. BUT, Secondly, How can they prove Impenetrability is an Essential Attribute of Body; or that Penetrability is an Essential Attribute of Spirit? Why may not Body be more or less impenetrable, and Spirit more or less penetrable, as it may, and indeed doth happen in all other Attributes? For, ex. gr. some Body may be more or less heavy or light, condensed or rarefied, solid or liquid, hot or cold; then why may it not also be more or less penetrable, or impenetrable? If it be said, that in all those other Mutations we always observe, that a Body remains impenetrable, as Iron when it is heat red-hot, yet remains still impenetrable: I Answer, I grant it may remain impenetrable of any other Body of equal thickness; yet may, and is entirely penetrated of a more subtile Body, sc. of the Fire which hath entred into it, and penetrated all its parts, whereby 'tis made so soft; and if the Fire be stronger, begins wholly to melt. But if, against this, they Object, that the ingress of Fire into the Iron, is not penetration in a Philosophical Sence, nor as they understand it, viz. as though the Fire and Iron did possess but one place, and so the one could be intrinsecally present in the other; because it is manifest to the contrary, that Iron (if it be made candent or glowing hot) it swelleth and acquireth a greater Bulk, than when it is cold; and as it waxeth cold again, it returneth to its former dimension. To this I Answer: If they mean such a Penetration, which we call Intrinseck Presence, viz. that one Homogeneal Substance should enter into another, both being of equal Dimensions, and yet the bulk or quantity not increased, that seems wholly irrational: And it would be a mere impossibility and contradiction to grant such an intimate Presence in Creatures, which only agrees unto God and Christ as Creators, whose Prerogative it is to be intrinsecally present in Creatures; whereas no Creature can have that Intrinseck Presence in its Fellow Creature, because then it would cease to be a Creature, and obtain one of the incommunicable Attributes of God and Christ, which is Intrinseck Presence. This (I say) is primarily to be attributed to God, and secondarily to Christ, in as much as he is Medium quid, or a certain Medium between God and Creatures, and who as he is Partaker of Mutability and Immutability, of Eternity and Time; so he may be said to be Partaker of Body and Spirit, and consequently of Place and Extension: For, in as much as his Body is of another Substance than the Bodies of all other Creatures, (as of whom he is the nearest Beginning to God,) it may be truly said, he is intrinsecally present in them, and yet not so as to be confounded with them. For to suppose one Creature intrinsecally present in another, so as to be mingled and most perfectly united with it, and yet its Quantity or Extension not increased, that confounds the Creatures, and maketh two or more to be but one: Yea, according to this Hypothesis, it may be said the whole Creation is reducible into the quantity of the least Grain or Dust, because every part would be supposed to penetrate another, and no greater extension follow than of one Part. But if it be said, that only proves that Spirits may be reduced into so small a space but not Bodies: Because Bodies are Impenetrable. I Answer, This is but a begging of the question, because they have not yet proved that Body and Spirit are distinct Substances; which, unless they are, it follows that one Nature is not more penetrable than the other, according to their sence. And indeed it seems very consentaneous to Reason, that as Times are each of them so extended into their due Measures and Extensions, that they cannot exceed those Bounds, and so cannot be intrinsecally present one with another; as (ex. gr.) the First Day of the Week cannot be present with the Second Day of the same Week; nor the First Hour of the Day with the Second; neither is the First Minute of an Hour present with the Second Minute thereof; because such is the Nature and Essence of Time, that it is successive, and hath partes extra partes, or parts, one without another. When nevertheless God is really and intrinsecally present in all Times, and is not changed, which cannot be said of the Creature, sc. that that is present in all or more Times, and not changed; for the Creature is perpetually changed with Times, seeing Times are nothing else but the Motion or Change of the Creature from one State or Condition into another. And as it is in the case of Time, and Creatures which are in Time, so also in the case of Place, Bulk, or Quantity; for as in God there is no Time, so also in him there is no Bulk or Corporeal Quantity; but in Creatures there is both Time and Corporeal Quantity; because otherwise they would be either God, or Nothing, which is impossible. For whatsoever Quantity, Bulk, or Extension any Creature hath, it retains the same, as something which is of its own Essence; as it is the Essence of Time to consist of more parts, and those again of more, and so ad infinitum: For it may be easily conceived how a less Time is in a greater, ex. gr. how so many Minutes are in an Hour, and so many Hours in a Day; and one Hour doth immediately touch the next, but cannot be present in it, the same is to be understood of the Creatures, in regard of their Quantity or Bulk; for indeed one Creature may immediately touch another, but cannot be present in all its parts, but only a less may be in a greater, and a subtiler in a grosser; and this is more properly Penetration which agrees to Bodies as well as Spirits; as some Body, that is less gross may penetrate another that is more gross; but two Bodies of an equal thickness cannot penetrate each other: The same may be said of Spirits which have their degrees of more or less grossness, as Bodies have: Neither is there any other difference between Body and Spirit, (if Body be not taken in their sence, who teach that it is a Thing merely Dead, and void of Life, or a Capacity thereof; but in a proper sence: sc. that it is an excellent Creature having Life and Sense, which either actually or potentially agrees to it) but this that a Body is the grosser part of a thing, and Spirit the subtiler, whence also Spirit hath it's name from the Air, which is the most subtile Nature in this visible World. In Kabbal. denud. Tom. 2. Tract. ult. p. 6. §. 13. Spirit is rather defined, a central Nature, having a Faculty to send forth a Sphere full of Light and to inlarge or contract the same, which properly seems to be Aristotle's εντελεχεια, and ibid. p. 28. §. 4. Matter is defined: A naked Centre, or a Point wanting Eradiation, which Aristotle understood by Privation: Whence we must conclude, that the Impenetrability of these Creatures is to be understood of their Centres: For the Hebrew Word, ךוח, which signifies a Spirit, signifies also Air; and because Air hath a very swift Motion, all swiftness of Motion is imputed to the Spirit in the moved Body: Hence out of Popular Ignorance, when in certain Bodies they perceived no Motion, they termed them Dead, wanting both Life and Spirit: But indeed there is no where any such Body that hath not Motion, and by consequence Life and Spirit. Therefore every Creature hath its due Quantity or Extension, which it cannot exceed, and wherein also it cannot be diminished.
