R. G. Bury, The Symposium of Plato

ἔστι δὲ τῶν καλῶν. This is object. genitive: cp. 201 E, 206 E. As Rettig notes, Diotima herself affects περὶ τὸ καλόν in preference to τοῦ καλοῦ (after ἔρως, etc.); and this may be used as an argument against Jahn-Usener's σύμφῃς.

εἰ δέ τις κτλ. For the omission of the apodosis, cp. 199 E εἰ γὰρ ἐροίμην κτλ.

σαφέστερον ἐρῶ. The preceding query had been ambiguously worded, since τῶν καλῶν might be taken either as a partitive gen. dependent on τί, or as an object. gen. with Ἔρως (τί being adverbial accus.): that the latter was the construction intended is now shown by the revised statement of the query— ὁ ἐρῶν...τί ἐρᾷ; I am inclined to suspect that we should read ὅρα (see 204 E n.) for ἐρῶ (ἐρᾷ MSS.).

ἔτι ποθεῖ. If we read ἐπιποθεῖ we must ascribe to the proposition its full force, “craves further”; the other exx. of the cpd. in Plato are Prot. 329 D τοῦτ᾽ ἐστὶν ὃ ἔτι ἐπιποθῶ: Laws 855 E. The former of these supports Rückert's ἔτι ἐπιποθεῖ.

Οὐ πάνυ...ἔτι. For οὐ πάνυ, cp. Meno 71 C (with Thompson's note).
