.... “We have experimental data, for one thing,” he replied. “For example, neurosurgeon Wilder Penfield electrically stimulated the brains of epilepsy patients and found he could cause them to move their arms or legs, turn their heads or eyes, talk, or swallow. Invariably the patient would respond by saying, ‘I didn’t do that. You did.’ According to Penfield, ‘the patient thinks of himself as having an existence separate from his body.’
“No matter how much Penfield probed the cerebral cortex, he said, ‘There is no place . . . where electrical stimulation will cause a patient to believe or to decide.’ That’s because those functions originate in the conscious self, not the brain. “A lot of subsequent research has validated this. When Roger Sperry and his team studied the differences between the brain’s right and left hemispheres, they discovered the mind has a causal power independent of the brain’s activities. This led Sperry to conclude materialism was false.
“Another study showed a delay between the time an electric shock was applied to the skin, its reaching the cerebral cortex, and the self-conscious perception of it by the person. This suggests the self is more than just a machine that reacts to stimuli as it receives them. In fact, the data from various research projects are so remarkable that Laurence C. Wood said, ‘many brain scientists have been compelled to postulate the existence of an immaterial mind.
“Furthermore, my consciousness is inner and private to me. By simply introspecting, I have a way of knowing about what’s happening in my mind that is not available to you, my doctor, or a neuroscientist. A scientist could know more about what’s happening in my brain than I do, but he couldn’t know more about what’s happening in my mind than I do. He has to ask me.”
When I asked Moreland for an illustration of this, he said, “Have you heard of Rapid Eye Movement?” “Sure,” I replied. “What does it indicate?” “Dreaming.” “Exactly. How do scientists know that when there is a certain eye movement that people are dreaming? They’ve had to wake people and ask them. Scientists could watch the eyes move and read a printout of what was physically happening in the brain, so they could correlate brain states with eye movements. But they didn’t know what was happening in the mind. Why? Because that’s inner and private. “So the scientist can know about the brain by studying it, but he can’t know about the mind without asking the person to reveal it, because conscious states have the feature of being inner or private but brain states don't.
