To what does the English word Soul refer to in your mind.
Not to be a bitch, but... words don't refer. People use words to attempt to refer. So I'd rephrase the question as, "what do you use the word 'soul' to attempt to refer to?"
When I talk to people who I think believe in an eternal soul, I use the word to refer to their conception of an eternal soul.
When I talk to people who don't believe in an eternal soul, I don't use the word soul.
When a person uses the word "soul" to attempt to refer, I take them to be referencing some idea of self. That misconception of individuality and separateness which makes me say,
"MINE!"
I think lots of people tend to use the word like Ringo, to talk about the "essence" of us--the things that make us human, make us good, make us worthwhile.. if I'm understanding Ringo properly. I wouldn't refer to that as "soul"... unless I was having a friendly dialog with Ringo using Ringo's terms.
