Excerpt About Brain
Intelligence needs the physical apparatus of the brain in order to express itself. So if you have brain damage, your capacity for intelligence will probably be limited. This is because, even though you have innate intelligence, the vehicle through which it expresses itself isn’t functioning optimally. It is as if you had a great capacity to sing but something was wrong with your vocal cords—you would be unable to sing, regardless of how wonderful your innate singing capacity was. Likewise, you could be very intelligent, but if you have brain damage, you won’t be able to express that intelligence. The point is that intelligence is not an innate property of the brain cells; it is a property of your consciousness, your soul.
