Sounds like Epicureanism needs its own glossary! Is there a good dictionary of Greek and Latin philosophical terms that makes this comparison between schools of thought? (I have one for Sanskrit..) I know there is a reference section for terms here. I will check that out too.
By the way, being the newbie here, I know I must be asking questions that have been thoroughly addressed in other threads or readings. I take no offence in simply being redirected to those sources if I have missed them. I'm grateful for your patience.
I am particularly interested the Epicurean theology, so I will be reading up on that.
