I studied Attic, Koine, and Homeric, as well as a few other dialects for 10 years through college until I left my PhD program in Classics. Learning Greek was _very_ hard and even after that time I still had many gaps.
There's certainly a lot to be said about the manifold interpretations of Platonic Idealism; what I'm saying is that when we've historically introduced new philosophy students to things like Jowett's translations ("But tell me, Zeno, do you not further think that there is an idea of likeness in itself, and another idea of unlikeness, which is the opposite of likeness, and that in these two, you and I and all other things to which we apply the term many, participate-things which participate in likeness become in that degree and manner like; and so far as they participate in unlikeness become in that degree unlike, or both like and unlike in the degree in which they participate in both?"), there's also a grammatical issue. Yes, I can deconstruct that and reassemble it in more colloquial terms. The problem is that for a lot of students, they don't develop interest enough to engage in the deconstruction until after they've gone through the arduous process of reading that and thinking "WTF?!"
I’m not convinced that better translations are doing much to fix the deeper issue in most readers: the lack of broad exposure to the Western canon which seems to cultivate a real preference for rigor over comfort.
I want to go try some Plato in Greek. Do you have the reference for that passage? (Thankfully I got the unabridged Liddell and Scott lexicon which encompasses Attic not just New Testament words so I’ve been able to read Homer.)
They probably had this attitude, but I didn't find it objectionable at all, and I'm not a native English speaker. If a 19-year old engineering student can't read that, even in his own language, what's the point? The guy's a bore.
I think it's probably better to just read them having picked them off a bookshelf than in a class though.
Plato is not exactly burning up the airwaves right now. Most likely the only exposure most people will have to this work (or any of the libraries of work that's been banned in this manner) would be at college, assigned to them for a class.
Now, if they actually banned a book, like "you will go to jail for having this" I would be concerned.
