Here is a thread for further discussion on the Torquatus section of Cicero's "On Ends". Back in the fall of 2021 the Lucretius Today Podcast covered this text. You can find the text here, and the first of that podcast here (Episode 93).
Back at that time I was still new to the forum, and so wasn't able to properly absorb it. Since then I have listened to the audio recording several times, as read by Joshua, which you can find here, and that significantly improved my understanding.
As I have studied Epicurean philosophy further, I have found that this narrative has its usefulness, and yet there are parts that need to be "unpacked" with care.
Here in this thread I want to present the highlights, and also point out (with a word of caution) parts which "muddy the waters". So I will post more soon.
