I need to go back and re-read that Nikolsky article, but I agree with your point that compilers decide what to compile. To paraphrase what you mentioned previously, the winners write the history and the compilers decide what to collect.
And I think I see your perspective on those last points. So then which comes first: The realization that pleasure is worthy of pursuit? Or the realization that there's no afterlife and it's acceptable to then pursue pleasure in the here and now? Or do they arise together? Or do we build each up as on the "Canon, Physics, Ethics" tripod? If this, then that. This isn't a criticism of your points. I'm just working through how we arrive at answers to those questions you posed. This is why I think it's important to see Epicurus's context and thought process in opposing the Cyrenaics and what they disagreed with in his philosophy. How did we get where we are?
Your thoughtful replies and posts are always appreciated! It definitely helps me hone my own thinking!
