It is of those opposites, then, and not of the different forms of matter, that everything contains a portion. Every particle, however large or however small, contains every one of those opposite qualities. That which is hot is also to a certain extent cold. Even snow, Anaxagoras affirmed, was black;[694] that is, even the white contains a certain portion of the opposite quality. It is enough to indicate the connexion of this with the views of Herakleitos (§ 80).[695] Footnote 694: Sext. _Pyrrh._ i. 33 (R. P. 161 b). Footnote 695: The connexion was already noted by the eclectic Herakleitean to whom I attribute Περὶ διαίτης, i. 3-4 (see above, Chap. III. p. 167, _n._ 383). Cf. the words ἔχει δὲ ἀπ’ ἀλλήλων τὸ μὲν πῦρ ἀπὸ τοῦ ὕδατος τὸ ὑγρόν· ἔνι γὰρ ἐν πυρὶ ὑγρότης· τὸ δὲ ὕδωρ ἀπὸ τοῦ πυρὸς τὸ ξηρόν· ἔνι γὰρ καὶ ἐν ὕδατι ξηρόν. [Sidenote: Seeds.] 130. The difference, then, between the theory of Anaxagoras and that of Empedokles is this. Empedokles had taught that, if you divide the various things which make up this world, and in particular the parts of the body, such as flesh, bones, and the like, far enough, you come to the four “roots” or elements, which are, accordingly, the ultimate reality. Anaxagoras held that, however far you may divide any of these things—and they are infinitely divisible—you never come to a part so small that it does not contain portions of all the opposites. The smallest portion of bone is still bone. On the other hand, everything can pass into everything else just because the “seeds,” as he called them, of each form of matter contain a portion of everything, that is, of all the opposites, though in different proportions. If we are to use the word “element” at all, it is these seeds that are the elements in the system of Anaxagoras. Aristotle expresses this by saying that Anaxagoras regards the ὁμοιομερῆ as στοιχεῖα.[696] We have seen that the term στοιχεῖον is of later date than Anaxagoras, and it is natural to suppose that the word ὁμοιομερῆ is also only Aristotle’s name for the “seeds.” In his own system, the ὁμοιομερῆ are intermediate between the elements (στοιχεῖα), of which they are composed, and the organs (ὄργανα), which are composed of them. The heart cannot be divided into hearts, but the parts of flesh are flesh. That being so, Aristotle’s statement is quite intelligible from his own point of view, but there is no reason for supposing that Anaxagoras expressed himself in that particular way. All we are entitled to infer is that he said the “seeds,” which he had substituted for the “roots” of Empedokles, were not the opposites in a state of separation, but each contained a portion of them all. If Anaxagoras had used the term “homoeomeries”[697] himself, it would be strange that Simplicius should quote no fragment containing it. Footnote 696:
