I haven't had time to read this article by Yosef Liebersohn, and I am not sure if or when I will, but this abstract that came across my email just reminded me for the 500th time of this issue. I'll skip over the fact that the author suggests that kinetic and katastematic are "the most dominant terms in Epicurus' theory of the pleasures (despite the fact that this comes from Cicero and Diogenes Laertius and isn't a significant factor at all in Epicurus' or Lucretius' work, as explained by Boris Nikolsky).
What's significant to me is that I have to hand it to this writer for creativity in taking the katastematic/kinetic argument that modern commentators love to discuss to what may be its logical extreme conclusion.
Once you identify "katastematic pleasure" as the ultimate goal that makes life worth living, it's easy and enticing to conclude that this "resting" or "static" type of pleasure is what is "necessary" in life, and that kinetic pleasure ("joy and delight" in Diogenes Laertius) is "unnecessary."
People who take this approach have always seemed to me to be intent on draining every last aspect of "joy and delight" out of Epicurean philosophy. Possibly this writer shows the most creative way to do that. So if you're of the persuasion to drain joy and delight out of Epicurean philosophy, by all means pursue the katastematic/kinetic distinction that leads to this form of analysis.
My own suggestion is - "Don't!"
