[699] Apollodorus, in the second century B. C., had before him some brief expository treatises of Anaximander (Diogen. Laërt. ii, 2): Περὶ Φύσεως, Γῆς Περίοδον, Περὶ τῶν Ἀπλανῶν καὶ Σφαῖραν καὶ ἄλλα τινά. Suidas, v. Ἀναξίμανδρος. Themistius. Orat. xxv, p. 317: ἐθάῤῥησε πρῶτος ὦν ἴσμεν Ἐλλήνων λόγον ἐξενεγκεῖν περὶ Φύσεως συγγεγραμμένον.
[700] Irenæus, ii, 19, (14) ap. Brandis, Handbuch der Geschichte der Griech. Röm. Philos. ch. xxxv, p. 133: “Anaximander hoc quod immensum est, omnium initium subjecit, seminaliter habens in semetipso omnium genesin, ex quo immensos mundos constare ait.” Aristotel. Physic. Auscult. iii, 4, p. 203, Bek. οὔτε γὰρ μάτην αὐτὸ οἶόν τε εἶναι (τὸ ἄπειρον), οὔτε ἄλλην ὑπάρχειν αὐτῷ δύναμιν, πλὴν ὡς ἀρχήν. Aristotle subjects this ἄπειρον to an elaborate discussion, in which he says very little more about Anaximander, who appears to have assumed it without anticipating discussion or objections. Whether Anaximander called his ἄπειρον divine, or god, as Tennemann (Gesch. Philos. i, 2, p. 67) and Panzerbieter affirm (ad Diogenis Apolloniat. Fragment. c. 13, p. 16,) I think doubtful: this is rather an inference which Aristotle elicits from his language. Yet in another passage, which is difficult to reconcile, Aristotle ascribes to Anaximander the water-doctrine of Thalês, (Aristotel. de Xenophane, p. 975. Bek.)
Anaximander seems to have followed speculations analogous to those of Thalês, in explaining the first production of the human race (Plutarch Placit. Philos. v, 19, p. 908), and in other matters (ibid. iii, 16, p. 896).
