Despite the different directions that some of these posts may have indicated, I think we can probably all agree that there is a distinct difference between the alternative guides of life offered by Epicurus vs the other Greeks.
The other Greeks were pointing to gods, or to "virtue," as absolutes which existed outside of the living human, either in heaven or in a realm of ideal forms or some other "external" place.
I think we would all agree that the "pleasure" to which Epicurus was pointing is not something that exists "in the air" in nature and does not exist apart from actual living beings, which to repeat what I wrote above, I think establishes that pleasure is an emergent property of those atoms and void which are so arranged and situated as to constitute living beings. So "pleasure" has no and can have no absolute existence in itself, it's going to be something ("a feeling" or "experience" or "affect" or whatever) that a living being experiences in the moment as part of its own existence, not something the living being pulls from somewhere else.
Anyone disagree or wish to tune that better?
