I've been stalled out on this one all week:
So Plato, Symposium, via Perseus. Kenneth Dover gives:
[200β] ...ἴσως γὰρ ἄν τις ταῦτα οἰηθείη καὶ πάντα τὰ τοιαῦτα τοὺς ὄντας
[200ξ] τε τοιούτους καὶ ἔχοντας ταῦτα τούτων ἅπερ ἔχουσι καὶ ἐπιθυμεῖν
For one might perhaps think (sc. on the subject of) those (sc. qualities) and everything of that kind that those who are such and possess those (sc. qualities) also desire those things (τούτων) which they have.
Plato, Symposium 135 (Cambridge Greek and Latin Classics ed.) Dover must think it tricky; Dover rarely gives this much specific help. Harold N, Fowler (Perseus) gives:
Since we are apt to suppose in these and all such cases that men of this or that sort, possessing these qualities, do also desire what they have already.
Joseph Epstein says: that Socrates; presentation was"tighter than Noël Coward's act at Vegas.” [Snobbery: The American Vision 104 (2002)]. I say I need to review my pronouns.
