I don't think there's any way for katastematic pleasure to have intensity, because if so it couldn't be perfect at every moment (we could always imagine that it could be a bit more intense
This is an intriguing comment!
A pleasure with no intensity would, to me, describe a neutral state, which of course doesn't exist for Epicurus in the pleasure/pain relationship. This is why I prefer "complete" to "perfect". To my understanding a pleasure or pain requires all three components of intensity, location and duration: if any one of these doesn't apply, how can a pleasure or pain be experienced? Further, to my way of thinking a katastematic pleasure can vary in intensity, say from contentment to joy.
On a related note, I'm not clear as to what constitutes a bodily katastematic pleasure. Or possibly any katastematic pleasure.... It would seem to me to be a matter of duration, of being "lasting". This gets into the squishy question of what is meant by "lasting". Eternal? Being around longer than most pleasures? Persisting regardless of any external circumstances or new information?
Being now a "senior citizen", it's become quite apparent to me that all bodily pleasures and pains come and go. This is the lens through which I view bodily katastematic feelings with suspicion, but of course it may have nothing to do with that I suppose. Does it have to to with a material world in which everything is ultimately physical?
