and no one could think of before Parmenides. The question has only been mentioned because it has given rise to a lengthy controversy, and because it throws light on the historical value of Aristotle's statements. From the point of view of his own system, these may be justified; but we shall have to remember in other cases that, when he seems to attribute an idea to some earlier thinker, we are not bound to take what he says in an historical sense.[1]
16.The primary substance is infinite. Anaximander's reason for conceiving the primary substance as boundless was, no doubt, as indicated by Aristotle, "that becoming might not fail."[2] It is not clear, however, that these words are his own, though the doxographers speak as if they were. It is enough for us that Theophrastos, who had seen his book, attributed the thought to him. And certainly his view of the world would bring home to him the need of a boundless stock of matter. The "opposites" are, we have seen, at war with one another, and their strife is marked by "unjust" encroachments on either side. The warm commits "injustice" in summer,
- ↑ For the literature of this controversy, see R. P. 15. Professor Heidel has shown in his "Qualitative Change in Pre-Socratic Philosophy" (Arch., xix. p. 333) that Aristotle misunderstood the Milesians because he could only think of their doctrine in terms of his own theory of ἀλλοίωσις. That is quite true, but it is equally true that they had no definite theory of their own with regard to the transformations of substance. The theory of an original "mixture" is quite as unhistorical as that of ἀλλοίωσις. Qualities were not yet distinguished from "things," and Thales doubtless said that water turned into vapour or ice without dreaming of any further questions. They all believed that in the long run there was only one "thing," and at last they came to the conclusion that all apparent differences were due to rarefaction and condensation. Theophrastos (ap. Simpl. Phys. 150, 22) says ἐνούσας γὰρ τὰς ἐναντιότας ἐν τῷ ὑποκειμένῳ . . . ἐκκρίνεσθαι. I do not believe these words are even a paraphrase of anything Anaximander said. They are merely an attempt to "accommodate" his views to Peripatetic ideas, and ἐνούσας is as unhistorical as the ὑποκείμενον.

Γ, 4. 203 b 18, a passage where Anaximander has just been named, τῷ οὕτως ἂν μόνον μὴ ὑπολείπειν γένεσιν καὶ φθοράν, εἰ ἄπειρον εἴη ὅθεν ἀφαιρεῖται τὸ γιγνόμενον. I cannot, however, believe that the arguments at the beginning of this chapter (203 b 7; R. P. 17) are Anaximander's. They bear the stamp of the Eleatic dialectic, and are, in fact, those of Melissos.
