I think where the analogy breaks down some, and the part that I have difficulty with (I believe it to be the same part Zilch may be referencing, though he may correct me if I'm wrong) is that indeed when a radio is broken it may pick up static, but it won't pick up different songs and programming from the same station (the station or frequency here serving as reference for the soul).
Indeed with Phineas Gage, Ann from Jenn's post, my grandmother as well as many others, the personality changes along with changes in the brain. The "songs are different", if you will.
I can only infer that the personality is in some way constructed by the brain, with consciousness serving as the witness.
Consciousness may be an entirely different thing altogether- it may simply turn out to be pure power of presence and observation, with personality being a layer added on top.
Dear Convolution, yet again, what you are saying here is based in bits of nonsense so your conclusions inevitably also are nonsense. But apparently playing with nonsense is what you enjoy?
