ANAXIMENESD Three Summaries Deriving Ultimately from Theophrastus (D1–D3)
D1 (< A5) Simplicius, Commentary on Aristotle’s Physics
Anaximenes [. . .] says too, as he [i.e. Anaximander] does, that the underlying nature is [scil. only] one and unlimited, but not that it is indeterminate, as he [i.e. Anaximander] does, but rather that it is determinate, for he says that it is air. It differs by its rarefaction or density according to the substances: rarefied, it becomes fire; condensed, wind, then cloud; even more, water, then earth, then stones; and everything else comes from these last. As for motion, he too considers it to be eternal; and it is because of it that change too comes about.
D2 (A6) Ps.-Plutarch, Stromata
They say that Anaximenes affirms that the principle of all things is air and that this is unlimited in kind but limited
