That's why I see the "logical extreme" interpretation of PD10 as so important -- I see Epicurus as saying that "IF we look at things his way," then a "pleasurable life" is a "pleasurable life" no matter what type of pleasure it contains, because we are using the term pleasure in a logically consistent way. From that perspective PD10 is an in-your-face assertion that pleasure is pleasure is pleasure.
I'll have to dig back in, but I don't think the language supports that interpretation, especially in light of the letter to Menoikeus. It seems to me he's giving practical advice in PD10, not necessarily making a grand philosophical point. I see this as directly countering the Cyrenaic position.
But I'll need to revisit this tonight after work.
