We are animals. We are flesh. Our personality is determined by the hormones and electrochemical activity in our brains. This is why medicine can be used to calm psychotics and schizophrenics. This is why chronically depressed people can live normal lives with the right medication. This is why people who have a functioning set of moral standards behave differently when drunk.
An immortal soul existing independently of this body and occupying it as though it were a car, would not be affected by changes to the car's engine.
I had struggled to understand the connection between the physical body and this supposedly separate soul, all during the time I was a Baptist and after I left that church in search of something that made sense. This is why I responded so readily to the witnesses' message when I heard it: it had the clear ring of truth to it. It was plain, simple, honest: there is no immortal soul. We are our bodies. That much is true.
