This appears to follow at once from the remark of Simmias in _Phd._ 64 b. The whole passage would be pointless if the words φιλόσοφος, φιλοσοφεῖν, φιλοσοφία had not in some way become familiar to the ordinary Theban of the fifth century. Now Herakleides Pontikos made Pythagoras invent the word, and expound it in a conversation with Leon, tyrant of Sikyon _or Phleious_. Cf. Diog. i. 12 (R. P. 3), viii. 8; Cic. _Tusc._ v. 3. 8; Döring in _Arch._ v. pp. 505 sqq. It seems to me that the way in which the term is introduced in the _Phaedo_ is fatal to the view that this is a Sokratic idea transferred by Herakleides to the Pythagoreans. Cf. also the remark of Alkidamas quoted by Arist. _Rhet._ Β, 23. 1398 b 18, Θήβησιν ἅμα οἱ προστάται φιλόσοφοι ἐγένοντο καὶ εὐδαιμόνησεν ἡ πόλις. Footnote 740: For reasons which will appear, I do not attach importance in this connexion to Philolaos, fr. 14 Diels = 23 Mullach (R. P. 89), but it does seem likely that the μυθολογῶν κομψὸς ἀνήρ of _Gorg._ 493 a 5 (R. P. 89 b) is responsible for the whole theory there given. He is certainly, in any case, the author of the τετρημένος πίθος, which implies the same general view. Now he is called ἴσως Σικελός τις ἢ Ἰταλικός, which means he was an Italian; for the Σικελός τις is merely an allusion to the Σικελὸς κομψὸς ἀνὴρ ποτὶ τὰν ματέρ’ ἔφα of Timokreon. We do not know of any Italian from whom Plato could have learnt these views except Philolaos or one of his disciples. They may, however, be originally Orphic for all that (cf. R. P. 89 a). We know further that Philolaos wrote on “numbers”; for Speusippos followed him in the account he gave of the Pythagorean theories on that subject.[741] It is probable that he busied himself mainly with arithmetic, and we can hardly doubt that his geometry was of the primitive type described in an earlier chapter. Eurytos was his disciple, and we have seen (§ 47) that his views were still very crude. Footnote 741: See above, Chap. II. p. 113, _n._ 236.
