There is so much good stuff coming up here in this thread, yet it feels just beyond my ability to adequately synthesize. Thank you Don for your work on translation, and Godfrey you added some good stuff too.
And Cassius thank you for holding the line and your explanation in the above post. I would add that your label of the "Wikipedia-Epicureans" would refer to the "tranquility-as-the-goal-Epicureans". You continue to uphold the "fullness-of-pleasure-Epicureans" as the best way to bring forward the philosophy to the next generation -- and which is why I came onto this forum.
I think there are many layers to all this, such as if someone is hoping for a therapeutic benefit from Epicureanism -- and yes I confess that is me!
Until we create a kind of "Epicurean bible" we will continue to have these discussions and it will be difficult to bring the philosophy to the next generation.
So what are we REALLY talking about in this issue?
Did Epicurus hold that the "healthy functioning of the organism" is a pleasure? HECK YES!Did Epicurus hold that a background sense of calmness and tranquility is also a pleasure? HECK YES!
Did Epicurus hold that a confident continuation of our present state of pleasure is also a pleasure? HECK YES!
Did Epicurus hold that our ideal state of functioning to be filling our experience pleasures and thereby eliminating from our experience all pains? HECK YES!
This is the kind of stuff that needs to go into a book (together with Epicurus' writings).
And I agree on not using the word "katastematic".
