of the Theorie, before that in seeking I had found some right Medicines which were suf∣ficient for those that had made a Beginning.
Wherefore seeing I was about to speak of Diseases, under so great a Paradox and weight of things, and sound none among the Antients and Modern Juniors to be my assistant, I [unspec 3] seriously invoked God, and I found him also favourable.
Therefore I determined before I wrote, to call upon Logick, that by its Definitions it might demonstrate unto me the Essences of Diseases; indeed by their Divisions, Species, [unspec 4] and interchangable courses or mutual respects; and at length, that by Augmentation, it might suggest the Causes, Properties, Meanes, and Remedies of knowing and curing them. But at my acclamations made even into its mouth, it was deaf, stood amazed, heard no∣thing, remained dumb, and helped not me miserable man in the least: Because it was wholly impotent, without sense.
Afterwards therefore, I called the Auricular Precepts of the natural Philosophy of the Schools, unto my aid: To wit, their three (boasted of) Principles, four causes, fortune, [unspec 5] chance, time, infinite, vacuum, motion, yea and monster. Whence at length, I disco∣vered, that their whole natural Philosophy, was truly monstrous, having feigned, false, mocking Beginnings, not principiating, and much less vital, in the sight of the King by whom all things live: likewise Causes, not causing. Also adding or obtruding the phan∣tastick Beings of Reason, and opinions beset with a thousand absurdities, wherein I as yet found not any footstep of Nature entire; and much less the defects of the same, or the in∣terchangable courses of faculties, or vital functions: But least of all, from such a structure of Principles, was the knowledge of Causes Natural, Vital, of Diseases, Remedies, and Cures to be fetched: Whither notwithstanding I supposed the knowledge of Nature had respect, as unto its objected scope. For whatsoever I sought for from the Schooles, and attempted to handle by their Theorie, that thing wholly Nature presently derided in the Practise, and it was accounted for a blast of Wind: She derided me, I say, (to speak more dictinctly) together with the Schooles, as ridiculous: And at length, she, together with my self, complained of so unvanquished stupidity Then also, Logick bewailed with me her impotent nakedness, and the vain boasting of the Schooles: Because she being that, which even hitherto was saluted the Inventer, and Searcher of Meanes, Causes, Tearms, and Sciences, grieved that she ought to confesse, that she was dumb no lesse in Diseases, than in the whole compact of Nature and also that she ought to desert her own professors, in so great a necessity of miseries 〈…〉〈…〉 she, by one loud laughter had derided also the natural Philosophies of Aristotle, and the blockish credulities of the World, and of so many Ages, if she her self had not been a non-being fiction, swollen only with the blast of pride.
Wherefore seeing Nature doth no where exist, or is seen, but in Individuals; there is need that I who am about to write of Diseases, have exactly known the Causes of particu∣lar [unspec 6] things, even as also it is of necessity for a Physitian, to have thorowly viewed those Causes individually, under the guilt of infernal punishment. Therefore it hath seemed to me, that the quiddities or essences, as well of things entire, as of those that are hurt, were to be searched into after the manner delivered, concerning the searching out of Sci∣ences. But seeing the Knowledge thus drank, may be unfolded, I have confirmed unto the Young Beginner, that an essential definition is to be explained by the Causes, and pro∣perties of these; which is nothing else besides a connexion of Causes, but not the Genus or general kind, and difference of the thing defined. But this is an unheard of Method of explaining, even as Logick the Inventress or finder out of Sciences hath feigned: And also seeing all that faculty is readily serviceable unto a discursive Philosophy, (for they do vainly run back unto the Genus of the thing defined, and the constitutive differences of the Species, for the Diseases which have never, and no where been known:) There∣fore, seeing it hath been hitherto unknown, that things themselves are nothing without or besides a connexion of the matter, and efficient Cause; By consequence also the Schools [unspec 7] have wanted a true Definition: That is, a right knowledge of Diseases. If therefore the Essence or thingliness of Diseases, and the condition of Diseasie properties, do issue out of their own immediate essential Causes; of necessity also, the knowledge of the aforesaid Diseases, and properties, is to be drawn out of the same Causes: Because the considerati∣on of Causes, is before the consideration of Diseases. Therefore I have already shewn, even unto a tiresomness, That the Essences of Natural things, are the matter, and efficient Cause connexed in acting: Therefore also, the Essence of every Disease, doth by a just definition, consist of those two Causes, and its knowledge is to be fetched out of the same.
