Perseus translation:
Then I will try to speak more clearly. We speak of being carried and of carrying, of being led and of leading, of being seen and of seeing; and you understand—do you not?—that in all such expressions the two parts differ one from the other in meaning, and how they differ.
What I think I need is a explanation of these three words: ἕτερα, ἀλλήλων, and ἕτερα. They must have antecedents in the list of paired terms stated by Socrates. However I don’t know how these words work, and how to link them to their antecedents. I requote the problematic phrase for ease of reference. Of course I know what is meant in English, but I don’t have a command of these Greek terms. Maybe a little “translationese” would help.
ἐστὶ is singular agreeing with neuter plural πάντα τὰ τοιαῦτα.
“You understand that all such things are different [ἕτερα] from one another [ἀλλήλων] and [you understand] how/in what way [ᾗ] [they are] different.”
Greek idiom is “you understand all such things, that they are different from one another” where English would be “you understand that all these things are different from one another.” The Greek construction here is like “I know thee who thou art.”
Oh, yes! My understanding of the sentence was faulty. I had the problematical phrase wrong in its relation to the sentence. Now I see. Many thanks!
I would have just gone on and accepted the translation, but it seemed that Plato was working hard on making “Socrates’s” philosophical method crystal clear, and I wanted to get this step down.
