τῷ δὴ ὑπὸ ἐπιθυμίας ἀρχομένῳ δουλεύοντί τε ἡδονῇ ἀνάγκη που τὸν ἐρώμενον ὡς ἥδιστον ἑαυτῷ παρασκευάζειν· νοσοῦντι δὲ πᾶν ἡδὺ τὸ μὴ ἀντιτεῖνον, κρεῖττον δὲ καὶ ἴσον ἐχθρόν. οὔτε δὴ κρείττω οὔτε ἰσούμενον ἑκὼν ἐραστὴς παιδικὰ ἀνέξεται, ἥττω δὲ καὶ ὑποδεέστερον ἀεὶ ἀπεργάζεται· ἥττων δὲ ἀμαθὴς σοφοῦ, δειλὸς ἀνδρείου, ἀδύνατος εἰπεῖν ῥητορικοῦ, βραδὺς ἀγχίνου. τοσούτων κακῶν καὶ ἔτι πλειόνων κατὰ τὴν διάνοιαν ἐραστὴν ἐρωμένῳ ἀνάγκη γιγνομένων τε καὶ φύσει ἐνόντων μὲν ἥδεσθαι, τὰ δὲ παρασκευάζειν, ἢ στέρεσθαι τοῦ παραυτίκα ἡδέος.
My question is about the last sentence. I understand that ἀνάγκη here takes ἐραστὴν as the subject of all the infinitives that follow. But ἀνάγκη can also take a subject in dative. Given this, is not the position of ἐρωμένῳ before it stylistically confusing? How to “tune in” so that this sentence reads smoothly in one’s mind?
