I am far too ignorant of Prof. Warren's work to offer an opinion, Alex, although I understand that he was the editor of the Cambridge Companion to Epicureanism. Don might know something more there...
DeWitt's book is easy to recommend--in fact, I need to read it again myself, as it's been a few years.
I think my next read will be Lucretius and the Transformation of Greek Wisdom, by David Sedley. I was very impressed with the selection that Don read while we were discussing the Plague of Athens at the end of DNR Book 6.
I'm glad you enjoy the podcast! Hopefully someone else will have a more helpful response, Alex ![]()
