Yes, my friend suggested that it had to do with the communal experience, the singing, the endorphin flow and all of that. The trouble, of course, is that acceptance of the ideology is the "ticket" needed for access to this pleasant experience. Not as much of a problem for children, perhaps--when I was small, I just assumed the adults around me were telling the truth. But when we grow older and wise up a bit, then a difficult choice has to be made.
Incorporating music into Epicurean practice is a great idea, if you ask me! I feel that Epicurus himself would have approved. He seems to have appreciated music. One of the things that put me off Buddhism was its rejection of music and theater--the suttas warn that people involved in these activities are bound for various hells.
So...maybe time to get started on the Epicurean songbook!
I would very much like to see an Epicurean movement which provides a sense of community in the same way that I experienced within the Buddhist grups I participated in. However, I am still trying to nail down the nuts and bolts of Epicurean philosophy, and also figure out how to hold in-person meetings.
That would be my wish too! Hopefully it will become more feasible once the Epicurean revival gains critical mass...
