selecting particular views of the "good" would be contradictory to the basics of the philosophy of an atomistic universe.
Everyone has a formulation in their mind about what is "good" and what is "true". And unless they have a materialist view and pragmatic pleasure goal, then their mental conceptions and words will all be based on something very different than the "Epicurean worldview".
And in addition, here on the forum our definition of "good" and "true" is anything that is synonymous to the original teachings of Epicurus. Until everyone is completely clear about what the original teachings of Epicurus are, then we can't move forward as easily. So we almost need an "Epicurean Bible".
And now, I am not so sure that having meetings at a UU church would work...as there can be a "religious" undercurrent (a loving/benevolent Universe) based on a worldview that is different than Epicurean worldview. Epicureans would say the "Universe" is indifferent. And what exactly is this "Universe"...Epicureans would cognate it differently than UU's.
