Um, I have a problem with the soul-as-radio-station analogy...
If your soul is unaffected by your body, i.e. brain-damage can't destroy your soul, then neither can experience, eh? It's all just modifying the brain, one destructively but there's nothing saying experience can't be destructive as well, mental trauma and all that. So what pops out at the other end? Is it you? What kind of personality does it have? Since all our personality is derived from genetics and experience, predisposition being the genetics, what makes whatever intangible creature controlling my body and brain "me"? Is it just gonna be a blank baby-level personality? Is it going to be an "idealized" personality? What if I don't like that version, what if I LIKE my flaws?
Not to mention if you DO suddenly change personality, whether by brain damage or whatever, even if somehow a personality is transferred to the soul, which of those personalities take precedence? The one pre-damage, or the one who will exist when the body finally dies and the souls zips off to sip pina colodas with Jesus?
Like, all this talk being "Oh if your antennae is busted, that doesn't destroy the radio station!" falls apart when you take the analogy further, because what is the music here? Eh? It's your personality, or consciousness, or whatever. But that comes from the brain. So it's more like playing a CD in your radio, or MP3. So the music *does* go away when it's all destroyed, the CD is busted, and file is corrupted, and what point does the radio station have at that juncture?
