I am not sure it is possible for any of us to become convinced that we have constructed the definitive statement of any of the Epicurean doctrines, even the major ones. Every time I talk to someone about them I end up saying it a little differently to customize it to the context. I can definitely see why Epicurus advised surrounding yourself with like minded people to discuss these issues regularly, and I don't think we have even scratched the surface for finding new and better ways to describe and convey the big picture. So I may not be new here but it's definitely beneficial to read your summary and every new one that gets posted.
And another part of it is that the interests and issues that concern us one day tend to shift to other areas over time. So the discussion never gets old and it's fascinating to hear and consider what different people find to be important.
