Mental illness may be like a damaged radio receiving a perfectly good signal. The signal itself hasn't necessarily disappeared; the damaged receiver introduces static, distortion, and interference, so the resulting sound no longer accurately reflects the original broadcast
If a radio is damaged, the classical channel doesn't suddenly become heavy metal. The channel doesn't become English AND Spanish.
When the brain suffers severe damage, an individual's personality can completely change. The difference between responsible, polite, even tempered, and impulsive, profane, and volatile is more than just static. This is the difference of descriptions for Phineus Gage before and after a 3.5 foot rod was blown through his frontal lobe.
Individuals with a severed corpus callosum often have dual consciousness. Split brain patient known as Paul S famously had one side of his brain wanting to be a draftsman, and the other an automobile racer. Dr. V.S. Ramachandran described another patient where one hemisphere was a theist and the other an atheist.
This isnt symptoms of faulty receiver. These cases (and many others like them) demonstrate consciousness is emergent properties of a physical brain.
