If the words quoted from Theophrastos by Simplicius, _Phys._ p. 24, 15 (R. P. 16), stood by themselves, no one would ever have supposed them to mean that Anaximander called the Boundless ἀρχή. They would naturally be rendered: “having been the first to introduce this name (_i.e._ τὸ ἄπειρον) for the ἀρχή”; but the words of Hippolytos (_Ref._ i. 6, 2), πρῶτος τοὔνομα καλέσας τῆς ἀρχῆς, have led nearly all writers to take the passage in the less obvious sense. We now know, however, that Hippolytos is no independent authority, but rests altogether on Theophrastos; so the natural view to take is that either his immediate source, or he himself, or a copyist, has dropped out τοῦτο before τοὔνομα, and corrupted κομίσας into καλέσας. It is not credible that Theophrastos made both statements. The other passage from Simplicius compared by Usener (p. 150, 23), πρῶτος αὐτὸς ἀρχὴν ὀνομάσας τὸ ὑποκείμενον, does not seem to me to have anything to do with the question. It means simply that Anaximander was the first to name the substratum as the “material cause,” which is a different point altogether. This is how Neuhäuser takes the passage (_Anaximander_, pp. 7 sqq.); but I cannot agree with him in holding that the _word_ ὑποκείμενον is ascribed to the Milesian. [Sidenote: Aristotle’s account of the theory.] 15. It was natural for Aristotle to regard this theory as an anticipation or presentiment of his own doctrine of “indeterminate matter.”[106] He knew very well, of course, that he himself was the author of that; but it is in accordance with his method to represent his own theories as the distinct formulation of truths which earlier thinkers had only guessed at. It was to be expected, then, that he should sometimes express the views of Anaximander in terms of the theory of “elements.” He knew too that the Boundless was a body,[107] though in his own system there was no room for anything corporeal prior to the elements; so he had to speak of it as a boundless body “alongside of” or “distinct from” the elements (παρὰ τὰ στοιχεῖα). So far as I know, no one has doubted that, when he uses this phrase, he is referring to Anaximander. Footnote 106: Arist. _Met._ Λ, 2. 1069 b 18 (R. P. 16 c). Footnote 107: This is taken for granted in _Phys._ Γ, 4. 203 a 16; 204 b 22 (R. P. 16 b), and stated in Γ, 8. 208 a 8 (R. P. 16 a). Cf. Simpl. _Phys._ p. 150, 20 (R. P. 18).
