In the last two years especially, there has been more focus on the forum and in the podcast to gain a deeper context of Epicurean philosophy through study of other textual sources such as Cicero, etc. This newer material might be of interest for the more advanced student.
Everyone needs to realize going in that they are going to have to make up their own minds about what Epicurus was really teaching, and that takes time and familiarity with the subject to achieve.
Yes. And yes to both comments above. I can’t avoid using my decades of training and experience as an attorney when I read or study a topic. As an advocate, I needed to parse not only the words but the motivations, and first-hand knowledge of every client and then every witness. We called that combination of evaluations testing credibility. So when I read the first-hand (as far as we know) writings of Epicurus in the Principal Doctrines and the Letters to his followers, I give those the most credibility compared to other sources. Sure, it is possible that someone has mistranslated or changed the words; even so, the original has more credibility than other sources.
For instance, the Letters of Epicurus’ successors, or Cicero (to a degree), or even Lucretius or Diogenes (both of them) repeat what they know of Epicurus’ teachings, but to me they already are second-hand. Even though they purport to support Epicurus, they are not as good as the original words we’ve verified are his words. I’m really intense about questioning the Vatican Sayings, by the way. And I guess I’d include the modern commentary writers from DeWitt, up to the very latest of the scholars who interpret and comment. I won’t say they are wrong, but I’m not accepting what they say to be the best explanation.
As far as the critics of Epicurus are concerned , their credibility is no higher than his supporters. I believe it is worth learning about what they say to some degree. Yet to me, that can get so deep in the woods that it becomes a miasma of distraction.
If the other less credible sources are clearly in agreement with the original writings, then no problem exists for me. If there is a question about the specific meaning of words, then I’m going to lean toward the original first. And if there is more information about the teachings in the non-original sources than in the originals, I’m very careful and willing to withhold total belief.
As far as conflicts in the original documents, like the Principal Doctrines versus the Letters, that doesn’t bother me too much because anyone who writes frequently on a subject can write inconsistencies in their pronouncements if we look hard enough. It is only human.
I would like to see us discuss the historical periods more often as crucial backgrounding for the teachings. Anxiety filled Greece during Epicurus’ writing life because of Alexander the Great’s death. And I think we can all see, anxiety was a principal target of his pleasure-pain principle. I’d like to discuss the dates Epicurus wrote the originals we have. I think that information could be helpful for us to resolve any possible inconsistencies among his writings, since everyone can further develop their ideas over time and say things slightly differently.
