I am confused by the use of ψεύδεσθαι in this passage, which seems to be taking active and passive meaning. Also, I don’t think that I understand correctly some of its genitive/accusative (with a preposition) objects.
P.R.2.382:
τί δέ; ἦν δ᾽ ἐγώ: ψεύδεσθαι θεὸς ἐθέλοι ἂν ἢ λόγῳ ἢ ἔργῳ φάντασμα προτείνων;
But what then, I said. Could a god be willing to decieve with speech or with deed, extending a phantasm?
οὐκ οἶδα, ἦ δ᾽ ὅς.
I don’t know, he said.
οὐκ οἶσθα, ἦν δ᾽ ἐγώ, ὅτι τό γε ὡς ἀληθῶς ψεῦδος, εἰ οἷόν τε τοῦτο εἰπεῖν, πάντες θεοί τε καὶ ἄνθρωποι μισοῦσιν;
You do not know, I said, that the true lie, if someone is able to say it, all gods and men hate him?
πῶς, ἔφη, λέγεις;
How do you mean?, he said.
οὕτως, ἦν δ᾽ ἐγώ, ὅτι τῷ κυριωτάτῳ που ἑαυτῶν ψεύδεσθαι καὶ περὶ τὰ κυριώτατα οὐδεὶς ἑκὼν ἐθέλει, ἀλλὰ πάντων μάλιστα φοβεῖται ἐκεῖ αὐτὸ κεκτῆσθαι.
This way, I said. That probably no one is voluntarily willing to be deceived of himself in the chiefest part and about the chiefest things, but fears of all things especially to have it [the lie] there.
οὐδὲ νῦν πω, ἦ δ᾽ ὅς, μανθάνω.
And I still do not understand you, he said.
οἴει γάρ τί με, ἔφην, σεμνὸν λέγειν: ἐγὼ δὲ λέγω ὅτι τῇ ψυχῇ περὶ τὰ ὄντα ψεύδεσθαί τε καὶ ἐψεῦσθαι καὶ ἀμαθῆ εἶναι καὶ ἐνταῦθα ἔχειν τε καὶ κεκτῆσθαι τὸ ψεῦδος πάντες ἥκιστα ἂν δέξαιντο, καὶ μισοῦσι μάλιστα αὐτὸ ἐν τῷ τοιούτῳ.
For you think me to be saying something mystical, I said. But I say that everyone would least accept being deceived in his soul about what is real and to be deceived [state] and to be ignorant of what is real and to have and acquire the lie there. And they especially hate it in such a place.
