CHAP. I. Of the Necessitie of the parts of Generation.
IT is a ruled case in Hippocrates his Bookes de dieta, Aristotle in his Booke of the length and shortnes of Life, Galen in his first Booke * 1.1 de sanitate tuenda, and at a word amongst all Philosophers & Phy∣sitians: That all things vnder the Moone which is (sayth Cicero in Scipio his dreame) vltima Coelo citima terris, the last in the Heauen and the nearest to the Earth; all thinges I say contayned within the Elements are subiect to corruption and dissolution. For eue∣ry singular and particular thing either hath life or is without it: if it be without life it is obnoxious to diuers alterations, in regard both of the first and second matter whereof it consisteth. For the first matter, it is alwayes in loue with new formes, and therefore most subiect to mutation, which the French Poet Sa∣lust * 1.2 expresseth vnder the comparison of a notorious Strumpet, on this manner.
Or like a Lais, whose vnconstant loue Doth euery day a thousand times remoue: * 1.3 Who's scarce vnfoulded from one youths imbraces, Yer in her thought another she imbraces: And the new pleasure of her wanton fire, Stirs in her still another new desire.
The second matter which consisteth of the Elements, because of their intestine discord (for they are contraries, and from contrariety comes all corruption) vrgeth continually the dissolution of the mixed body.
The Elements themselues whilst they are out of their proper places, although they bee naturally linked together, yet it is not without a kinde of violence and constraint, and ther∣fore doe instantly long to returne into their proper seates.
But if the body be animated and haue life, beside those already named, it hath also other * 1.4 causes of dissolution bred with it; which no art, no industry of man can auoyde, no not so much as represse: so all things which haue any kinde of life, especially liuing and mouing creatures are destined to corruption, 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, that is, by Nature & necessity. By Nature * 1.5 because of the exhaustion or expence of the Primigenie moysture by the Elementary heat and the continuall effluxion of the threefold substance. By Necessity because of the per∣mixtion * 1.6 of the Aliments and the increase of excrements, the suppression whereof maketh an oppression of the partes, stableth vp a fruitfull nursery of diseases, and finally induceth death it selfe.
Wherefore Nature whome Hippocrates calleth 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉 Recta facientem and the * 1.7 ordinary power of God, being a diligent and carefull prouider for her selfe, hath giuen to euery thing a certaine appetite of eternity, which because shee could not performe in the Indiuiduum or particular Creature, because of the mortality of their Nature, she indeuou∣red to accomplish by propagation of formes and the species or kinds of things; as in the E∣lements by transmutation of one into another, in Minerals by apposition, & in Creatures
