Thank you Kalosyni and good catch as to "intrinsic value." I think we're on safe ground to assert that the only thing Epicurus would label as "intrisically desirable" (which I interpret as the meaning of "intrinsic value) is pleasure itself. Friendship might come close, depending on one's definition of it, but I think the way most people speak and understand the terms Friendship would generally be thought of as a tool for achieving pleasure, but not a pleasure itself.
That takes us toward definitional rabbit holes but I wonder if anything can be defined as "always" a pleasure other than pleasure itself.
Perhaps "joy" and "delight" and other words which are always associated with "pleasure," and maybe even "tranquility," but I would think that whatever we're discussing would have to be something that we "always" consider to be pleasurable. In that regard, "friendship" is probably tricky to classify.
What do others here think about that?
