No one is denying that. Clearly, memory requires a mostly functional head in which to form, or be retrieved. (I say “mostly” because memory is rather stable compared to other brain functions).
But some form of memory needs to be carried on after death, else nothing is left of a human being. They lost consciousness; they lost their bodies. What else but memory remains of that person’s life?
Memory may not be experessible in certain brain states, but if Eternal Life is at all possible, it must somehow be keyed to the “soul.”
Personality is given more importance than it probably has. It is IMNAAHO just the expressive surface that our mind presents to society; and it changes all the time, based on blood chemistry, health state, fatigue, emotional state, etc. No bolt through the forehead required.
