The word אפיקורסות comes from Epicurus' philosophy in general
As does "epicure." It's just interesting to note that even someone whose "view of the goal of
human life [was] happiness, resulting from absence of physical pain and mental disturbance"
advocated curbing your ambitions regarding pleasures and possessions.
(Note: Those images are distorted. I was supposed to keep tweaking
their proportions, but for whatever reason, I ended up not doing so.)
