I'm skeptical now to say that VS20 = PD29 since we've seen some discrepancies in a one-to-one duplication of VS's and PD's.
The transcription of this VS/PD appears to run here:
τῶν ἐπιθυμιῶν αἱ μέν εἰσι φυσικαὶ καὶ ἀναγκαῖαι, αἱ δὲ φυσικαὶ καὶ pasted-from-clipboard.png ἀναγκαῖαι, δὲ αἱ δὲ οὔτε φυσικαὶ οὔτε ἀναγκαῖαι, ἀλλὰ παρὰ κενὴν δόξαν γινόμαι.
Now the usual transcription and translation run:
τῶν ἐπιθυμιῶν αἱ μέν εἰσι φυσικαὶ καὶ <ἀναγκαῖαι, αἱ δὲ φυσικαὶ καὶ> οὐκ ἀναγκαῖαι, αἱ δὲ οὔτε φυσικαὶ οὔτε ἀναγκαῖαι, ἀλλὰ παρὰ κενὴν δόξαν γινόμεναι.
Among desires, some are natural and necessary, some are natural and unnecessary, and some are unnatural and unnecessary (arising instead from groundless opinion).
You can compare the discrepancies in the manuscript vs the usual transcription.
