I see evidence that Epicurean teachings are far more widespread than many think it to be. Epicurus' name is not attached to the actions and beliefs of people, especially in western, educated, Industrialized, rich, democracies (WEIRD). Just listen to any marketing of medical providers and pharmaceuticals, and you hear reduction of pain and suffering as a goal that can be achieved.
I see Epicurean beliefs as unstoppable.
I think that the term "Epicurean" can't be applied to someone who only has one single concept that they follow which might be considered "Epicurean". Epicureanism is a collection of specific concepts that guide one's outlook and choices.
This illustrates an on-going problem with speaking about "Epicureanism" -- how it is understood, what does it represent, what is "Epicureanism" and what isn't "Epicureanism" and who do we consider as "being Epicurean" - these questions will be answered differently depending on whom you ask. And the only way to begin to deal with this is to start labeling all of the common varying interpretations.
Here is an example: You could call something "Torquatian Epicureanism" or "Herodotian Epicureanism" or "PD08 Epicureanism" or "PD26 Epicureanism" etc, etc, (minimalists, maximalists, etc.)...depending on how things are interpreted.
Also, of importance is a list of "Epicurean beliefs", which would be within various outlines of Epicurean philosophy.
