Wherefore Hobbs, and all others who side with him, grievously erre, whilst they teach that Sense and Knowledge is no other than a re-action of Corporeal Particles one upon another, where, by re-action, he means no other than Local and Mechanical; Motion. But indeed Sense and Knowledge is a Thing far more Noble and Divine, than any Local or Mechanical, Motion of any Particles whatsoever; for it is the Motion or Action of Life, which uses the other as its Instrument, whose Service consists herein; that is, to stir up a Vital Action in the Subject or Percipient; and can like Local Motion be transmitted through divers Bodies, although very far distant asunder, which therefore are united, and that without any new Transition of Body or Matter, ex. gr. a Beam of Wood of an exceeding great length, is moved by one Extream from the North to the South, the other Extream will necessarily be moved also; and the Action is transmitted through the whole Beam, without any Particles of Matter sent hither to promote Motion, from one Extream to the other; because the Beam it self is sufficient to transmit the said Motion: After the same manner also, a Vital Action can proceed together with Local Motion from one thing to another, and that too at a great distance, where there is an apt and fit Medium to transmit it, and here we may observe a kind of Divine Spirituality or Subtilty in every Motion, and so in every Action of Life, which no created Body or Substance is capable of, viz. by Intrinsecal Presence, which (as before is proved) agrees to no created Substance; and yet agrees to every Motion or Action whatsoever: For Motion or Action is not a certain Matter or Substance, but only a manner of its Being; and therefore is intrinsecally present in the Subject, whereof there is a Modus, or Manner, and can pass from Body to Body, at a great distance, if it finds a fit Medium to transmit it; and by how much the stronger the Motion is, so much the farther it reacheth; so when a Stone is cast into standing Waters, it causes a Motion every way from the Centre to the Circumference, forming Circles still greater and greater at a great distance, by how much longer the time is, till at length it vanishes from our sight; and then without doubt, it makes yet more invisible Circles for a longer space of Time, which our dull Senses cannot apprehend, and this Motion is transmitted from the Centre to the Circumference, not conveighed thither by any Body or Substance, carrying this Motion with it from the Stone. And as the External Light also, seeing it is an Action or Motion stirred up by some illuminate Body, may be transmitted through Glass, Chrystal, or any other transparent Body, without out any Substance, Body, or Matter, conveighed from that illuminate Body from whence the said Action proceeded, not that I would deny that abundance of subtile Matter continually flows from all illuminate Bodies, so that the whole Substance of a burning Candle is spent in such Emanations: And this hath in it that Motion or Action, which we call Light; but this Motion or Action may be increased, v. g. by Chrystal, where those subtile Emanations of Bodies may be restrained, that they cannot pass out at least in such abundance, as may be sufficient to communicate the whole Light: But seeing Chrystal (which doth so easily transmit the Light) is so hard and solid, How can it receive so many Bodies, and transmit them so easily through it, when other Bodies, neither so hard nor solid, do let or resist it? for Wood is neither so hard nor solid as Chrystal, and yet Chrystal is transparent, but Wood not; and certainly Wood is more porous than Chrystal, because it is less solid, and consequently the Light doth not enter by the Pores of the Chrystal, but through the very Substance of it; and yet so as not to adhere to it, or make any turgescency or increase of Quantity, but by a certain intrinseck presence, because it is not a Body or Substance, but a mere Action or Motion. Now Chrystal is a fitter Medium to receive this Motion, which we call Light, than Wood is; and hence it is, that it pervades or passeth through that and not this; and as there is a great diversity of the Motion and Operation of Bodies, so every Motion requires its proper Medium to transmit the same. Therefore 'tis manifest, that Motion may be transmitted through diverse Bodies, by another kind of penetration, than any Body or Matter (how subtile soever it be) is able to make; to wit, by intrinseck Presence. And if mere Local or Mechanical Motion can do that, then certainly a Vital Action (which is a nobler kind of Motion) can do the same; and if it can penetrate those Bodies, it passeth through by intrinseck Presence, then it may in one moment be transmitted from one Body to another, or rather require no time at all, I mean Motion or Action it self requires not the least time for its transmission, although 'tis impossible but that the Body, wherein the Motion is carried from place to place, ought to have some time, either greater or lesser, according to the quality of Body and vehemency of Motion which carries it.
