In reading Cassius' article some questions and thoughts came up for me.
1. When Cicero uses Torquatus as the spokesman for Epicureans even though he (Torquatus) was a military man whose life was dictated by duty such that he was living life in a manner likely not recommended by Epicurus, does this in any way undermine or alter the reader's (of "On Ends") attitude toward Epicureans?
2. Some new ideas after reading this: "Absence of pain is the highest pleasure" is different than saying something like: "any pleasure without pain is the best kind of pleasure we can experience". And I now think it is possible that "absence of pain is the highest pleasure" is to be used as a remedy just like "death is nothing to us". It is a remedy for discontent, when you feel discontent even though you have everything you could possibly need: then you consider how absence of pain is the highest pleasure.
