CHAP. VIII. The Seat prepared.
IT is not sufficient to have demonstrated, that the causes of the Pest are unknown to the Schools, unless I shall declare my own experiences, the cause of the plague, its di∣vers progresses in the making, its strange properties in its being made, its preservations, and cure. At first therefore, I will repeat what I have demonstrated elsewhere; to wit, that in Nature, there are at least two causes, and no more: Indeed the matter, and effici∣ents which efficient in the plague, I call the Archeus, Vulcan, or Seed: at leastwise, for the matter, there is not a certain undistinct hyle or matter, which never existed, nor will be in nature: and it serves for Science Mathematical, and not to a contemplater of Na∣ture: Therefore, I behold the matter of the pestilence, with relation unto its internal efficient. The matter therefore of the plague, is a wild spirit tinged with a poyson: But that matter tends unto the end proposed to it self, after a three-fold manner; because it either comes to us from without, and being totally and perfectly pestiferous, exhaling from a pestilent sick person, or dead carkass, or place, or Utensile being defiled; or it is drawn inwards, being as yet crude, from a Gas of the earth putrified by continuance, which afterwards receives an appropriative ferment within; and at length, by degrees, attains a pestilent poyson in us: Or also a total destruction of us, is now and then materially, and formally finished within, without an external assistance. But that there are not more man∣ners, whereby the plague is made, is manifest from the division: For either it is wholly generated within, without a forraign aid; or it happens on us from without; and that is either perfect in the matter, and form of a poyson, wanting only appropriation, and ap∣plication; or it is as yet crude, imperfect, and as it were an Embryo. Whence at least∣wise, first of all, it becomes easie to be seen, that the Pest doth not always first invade the heart: For I have seen him, who in touching pestilent papers, at that very moment felt a pain, as it were of a pricking Needle, and straightway he shewed a pestilent Carbuncle in his fore-finger, and after two daies died.
Furthermore, the aforesaid three-fold matter, however plainly venemous the first is; yet on both sides, it holds it self within the number of an antecedent cause: For no o∣therwise than as poyson taken in at the mouth, is not the disease it self, or death, but on∣ly the occasional cause thereof: For not any thing that is corporeal, acteth immediately on the li••e o•• vital powers (because they are those which are of the nature of Coelessial lights) but first it is received, and made as it were domestical: and when some poyson is now made a Citizen of our Inn, to wit, it being swallowed or attracted; notwithstanding al∣so, it cannot as yet enter, or be admitted unto the hidden Seminaries of the vital pow∣ers (because it is in its whole essence external) but first, the poysonous quality, by acting on the life, stirs up the Archeus (otherwise the Author and workman of all other things to be done under his own government) into its own defence: For otherwise, a pestilen•• poyson acteth not like a sword, which equally wounds all it toucheth at, in the same mo∣ment of it self; but the pestilent poyson is not able to strike any. The Archeus therefore, since from his own disposition, he hath animal perturbations, passions, confusions, and interchangeable courses, he suddenly brings forth the image of his own alteration con∣ceived, and decyphers that Idea in the particle or small portion of his own proper sub∣stance wherein it is conceived; which Image of Death being thus furnished, is the Pest or Plague it self. For truly, I do not judge the plague to be a certain naked quality, al∣though it existeth not elsewhere than in a body, as it were accidents in a subject of inhe∣rency: but the plague is a Being, a poyson of Nature, subsisting by it self in us, and con∣sisting of its own matter, form, and properties; the which I have elsewhere most fully demonstrated in the Treatise of Diseases.
But here it is sufficient to have admonished, that the life operates nothing by conquer∣ing, or destroying, unless by the vital motions of the sensitive Soul, which is not wont but to operate by Idea's on the Archeus the Executer of any motions whatsoever; even as, neither doth the Archeus operate after any other manner on the body. Wherefore, it is to be noted by the way, in this place, that the inward material and immediate cause
