239a rare G

Specific Text Questions Phaedrus
1

τοσούτων κακῶν καὶ ἔτι πλειόνων κατὰ τὴν διάνοιαν ἐραστὴν ἐρωμένῳ ἀνάγκη γιγνομένων τε καὶ φύσει ἐνόντων τῶν μὲν ἥδεσθαι, τὰ δὲ παρασκευάζειν, ἢ στέρεσθαι τοῦ παραυτίκα ἡδέος

τοσούτων κακῶν καὶ ἔτι πλειόνων , are Partitive G but τῶν μὲν ἥδεσθαι, is either poetic or should be emended into D

2

I take the initial genitives as gen. absolutes (with γιγνομένων τε καὶ φύσει ἐνόντων predicative).
But I must admit I’m tempted by τοῖς μὲν ἥδεσθαι, easily corrupted.
