Maybe it’s just “blue car syndrome,” but I’ve come across the word ἀμαθία, (ignorance, stupidity, or folly, the antithesis of σοφία, “wisdom”) four or five times in the past month. It’s not a word I’d noticed much before, nor paid overly much attention to.
The idea that philosophy is the instrument of fortitude, protection, and freedom is interesting. Why do you have to sell Lucillius so hard on this? Is he not already committed? Maybe the issue is that the fruits of this particular tree are long in ripening?
Your concerns about conversation are also of particular interest to me lately. Most of Stoic philosophy is happening online these days, and almost all of it through text. This amounts to the ‘harangues’ which you’ve mentioned. Shouted at the top of one’s lungs, as it were.
This is not good for sustained development of the school. We need to get real humans in real life, face to face. We need Stoic communities.
