Edit: I neglected to mention that I discovered DeWitt via NewEpicurean.com, so I have you to thank for that!
Excellent!
Thanks for taking the time to write the description. That tells me that I need to focus on aspect of the "survey" on how much of the "original sources" people have read.
For example, have you read Diogenes Laertius from start to finish? Have you read any of "On Ends"? I have only recently discovered myself that while the Epicurean sections are of tremendous interest, the entire rest of the book too gives great insight. It is as if - and I did not realize this - Cicero was really setting out to cover all the bases from all the schools and give a good grounding in each. So there is a LOT to be learned even from the other chapters.
I am totally with you on the difficulty of Lucretius. I started and stopped reading it so many times over 50 years that I can hardly remember. But I finally got past my problems, and now I see it as a true gold mine. That is why i'm getting interested in a book review series on that -- I think if we can make that more accessible we can really add something to the discussion.
I am thinking that I need to set up some kind of spreadsheet with these core books.
How about Frances Wright? Did you read "A Few Days In Athens?"
