for me the soul is an idea that represents the sum of the everything i am, have experienced, and feel inside. without my soul, i would be an animal, a piece of meat still capable of living but without feeling. note that i don't attribute thought or logic to the soul. thought and logic happen in the brain. sensory feeling happens in the brain. conscious, subconscious and irrational thought go on in the brain. no, what i'm talking about is the feeling you get when you are really in love, the feeling you get when you really hate someone, the feeling you get when you watch your child grow into a good person or into a loser who kills himself, the feelings you get from watching things that don't concern you, which someone without a soul would see and feel unmoved in any way. i know this is a pretty bad attempt at trying to give my idea of what a soul might be, but i think it is a real idea and is definitely something we all have
