CHAP. II. What difference there is betweene a principle and an element. [ 20]
ARistotle and Plato are of opinion, that there is a difference betweene a Principle and an Element; but Thales Milesius thinketh they be both one: howbeit, there is a great diffe∣rence betweene the one and the other; for elements be compounded; whereas we holde, that the first Principles neither be compounded, nor are any complet substance: and verily, earth, water, aire, and fire, we tearme Elements; but Principles we call other Natures in this respect, that there is nothing precedent or before them, wherof they are ingendred; for otherwise, if they were not the first, they should in no wise be Principles, but that rather were to be so called, wher∣of they be ingendred. Now certeine things there are precedent, whereof, earth and water, &c. be [ 30] composed; to wit, the first matter, without all forme and shape; as also the first forme it selfe, which we call Entelechia; and thirdly, Privation. Thales therefore is in an error, when he saith, that water was both the Element and Principle or first beginning of all things.
