Wow, what a way to write off something "foundational to western literature".

I studied koine Greek with my dad. Today, I study Aristotle alongside half-a-dozen English translations (the latest, Adam Beresford's Ethics, is hilarious, "like Han Solo and Chewbacca, Achilles and Patrocles" in the notes; his Aristotle uses "Perhaps...but that's a bit off-topic").

None of the English translations is as convincing as knowing the original vocabulary. Many phrases and idioms are still obscure or debated. Why should the student not want to look behind the curtain?

Finally, there is something bracing about knowing the ancient grammar. Greek has features long-vanished from English.

You would separate students into those who never need to bother looking a bit into "foundational to western literature" and those handful who are on a PhD track. Eventually, nobody would grow up to be recruited into the latter.
