Oh, this looks promising?
This was written by Elias Tempelis (Professor of Philosophy at the Hellenic Naval Academy) to accompany his presentation for the 9th Panhellenic Symposium of Epicurean Philosophy.
His interpretation also excludes the quote Elli rejects, but he argues that most of the letter contains quotes from our school (with Porphyry only parenthetically adding his objectionable content). So Tempelis represents the most "optimistic" interpretation. I am inclined to agree.
Thank you for sharing this, Don. I do not think we discussed it.
