Anaxagoras the Clazomenian asserted Homoeomeries (or parts similar or homogeneous) to be the original cause of all beings; it seemed to him impossible that any thing could arise of nothing or be resolved into nothing. Let us therefore instance in nourishment, which appears simple and uniform, such as bread which we owe to Ceres, and water which we drink. Of this very nutriment, our hair, our veins, our arteries, nerves, bones, and all our other parts are nourished. These things thus being performed, it must be granted that the nourishment which is received by us contains all those things by which these parts of us are increased. In it there are those particles which are producers of blood, bones, nerves, and all other parts; which particles (as he thought) reason discovers for us. For it is not necessary that we should reduce all things under the objects of sense; for bread and water are fitted to the senses, yet in them there are those particles latent which are discoverable only by reason. It being therefore evident that there are particles in the nourishment similar to what is produced thereby, he terms these homogeneous parts, averring that they are the principles of beings. Matter is according to him these similar parts, and the efficient cause is a Mind, which orders all things that have an existence. Thus he begins his discourse: “All things were confused one among another; but Mind divided and reduced them to order.” In this he is to be commended, that he yokes together matter and an intellectual agent. Archelaus the son of Apollodorus, the Athenian, pronounceth, that the principles of all things have their original from an infinite air rarefied or condensed. Air rarefied is fire, condensed is water. These philosophers, the followers of Thales, succeeding one another, made up that sect which takes to itself the denomination of the Ionic. * * * * *
