Whither? To pleasure
Right and I agree. But if your paradigm is that life (without pain) IS pleasure, then aligning ones perspective in that direction might result in major terminology shifts, such as when the Epicureans continued to use the word "God" to refer to beings that the people of the day construed as most ungodlike.
No doubt, like Cicero said, people don't normally talk that way. But I have to think that in insisting that as to a normal and ordinary "hand," and as to the equation of the pourer to the drinker, that they are all in the state of greatest pleasure, and as to holding dogmatically that all we need to know about someone to say that they are in the greatest pleasure is that they say they are without pain - in those examples something is being telegraphed to us that we may find unintelligible due to our perspectives today, but which indicates a resolution to much that seems puzzling about Epicurus.
