The Society of Friends of Epicurus accepts a "third interpretation" of Epicurean theology, in addition to the alleged (1) Idealist and (2) Realist camps ... which I'll just gloss over for the sake of not bogging us down into a partisan philosophical debate
. This third camp is a (3) Non-Theistic interpretation, primarily represented by those of us who are, to be frank, just sort of turned-off by the entire idea of "God" as it is overwhelmingly presented throughout numerous parts of our culture.
Personally, I feel this, but I'm not sure its the best way to express Epicurus' thoughts on piety.
