Unwinding the katestematic/kinetic issue, and these issues that we are talking about in this section, could and would consume our entire attention if we let it. Here's another article that came through my email today on the same topic asking the same questions:
We can and will continue to discuss this issue because it is like a veil over the whole of Epicurean philosophy, and unless we lift it we never get to actually living and applying the Epicurean worldview. That's one of the reasons I think I will always see Lucretius as the real starting point to Epicurus. Lucretius explains the nature of the world and our place in it in practical terms and he never gets lost in "absence of pain" or seems to consider this issue important at all. I don't really think that Epicurus or the founding Greek Epicureans did either, thus we don't see this issue obsessed over in the texts we have left, and there's no hint that it was a major topic in other texts that are lost.
Our challenge, I think, is to articulate an understandable and coherent big picture overview of Epicurean philosophy and then get back to the original task: living life as happily as possible. That means spending as much time as possible with friends who also share the same perspective, and (given the nature of things) that in itself means that we have to train ourselves like Lucretius to be able to present the big picture in a persuasive way without being sidetracked by our philosophic enemies.
In fact, it is tempting to trace the decline and fall of the Epicurean period to the time of Cicero and his elevation of these word-game arguments to the heart of the discussion. Very little confident forward-thinking successful Epicurean writing has emerged in the 2000 years since this the time of Lucretius and the philosophy got hijacked into this sidetrack of a discussion. Most of the ink spilled on this topic has been an absolute waste - which again I think was Cicero's intention, picked up by many others along the way.
