“What about beyond the laboratory?” I asked.
“There are valid philosophical arguments as well,” he said. “For instance, I know that consciousness isn’t a physical phenomenon because there are things that are true of my consciousness that aren’t true of anything physical.”
“For instance . . . ,” I said, prompting him further.
“For example, some of my thoughts have the attribute of being true. Tragically, some of my thoughts have the attribute of being false—like the Chicago Bears are going to go to the Super Bowl,” he said with a chuckle. “However, none of my brain states are true or false. No scientist can look at the state of my brain and say, ‘Oh, that particular brain state is true and that one’s false.’ So there’s something true of my conscious states that are not true of any of my brain states, and consequently they can’t be the same thing.
“Nothing in my brain is
about
anything. You can’t open up my head and say, ‘You see this electrical pattern in the left hemisphere of J. P. Moreland’s brain? That’s about the Bears.’ Your brain states aren’t
about
anything, but some of my mental states are. So they’re different.
“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 and private, but the brain’s states don’t.”
THE REALITY OF THE SOUL
For centuries, the human soul has enchanted poets, intrigued theologians, challenged philosophers, and dumbfounded scientists. Mystics, like Teresa of Åvila in the sixteenth century, have described it eloquently: “I began to think of the soul as if it were a castle made of a single diamond or of very clear crystal, in which there are many rooms, just as in heaven there are many mansions.”

Moreland was understandably more precise in analyzing the soul, though unfortunately less poetic. He had already clarified that the soul contains our consciousness. Still, he hadn’t offered any reason to believe that the soul is an actual entity. It was time, I felt, to press him on this issue. “What makes you think that the soul is real?” I asked.
Moreland replied by saying, “First, we’re aware that we’re different from our consciousness and our body. We know that we’re beings who have consciousness and a body, but we’re not merely the same thing as our conscious life or our physical life.
“Let me give you an illustration of how we’re not the same thing as our personality traits, our memories, and our consciousness. I had a student a few years ago whose sister had a terrible accident on her honeymoon. She was knocked unconscious and lost all of her memories and a good bit of her personality. She did not believe she had been married. As she began to recover, they showed her videos of the wedding to convince her that she had actually married her husband. She eventually got to the point where she believed it, and she got remarried to him.
“Now, we all knew this was the same person all along. This was Jamie’s sister. She was not a different person, though she was behaving differently. But she had totally different memories. She had lost her old memories and she didn’t even have the same personality. What that proves is you can be the same person even if you lose old memories and gain new memories, or you lose some of your old personality traits and gain new personality traits.
“Now, if I were just my consciousness, when my consciousness was different, I’d be a different person. But we know that I can be the same person even though my consciousness changes, so I can’t be the same thing as my consciousness. I’ve got to be the ‘self,’ or soul, that contains my consciousness.
“Same with my body. I can’t be the same thing as my body or brain. There was a story on television about an epileptic who underwent an operation in which surgeons removed fifty-three percent of her brain. When she woke up, nobody said, ‘We have forty-seven percent of a person here.’ A person can’t be divided into pieces. You are either a person or you’re not. But your brain and your body can be divided. So that means I can’t be the same thing as my body.”
Those illustrations helped, though I said, “The fact that the soul and consciousness are invisible makes it difficult to conceptualize them.”
“Sure, that’s true,” he replied. “My soul and my consciousness are invisible, though my body is visible. That’s another distinction. In fact, I remember the time when my daughter was in the fifth grade and we were having family prayers. She said, ‘Dad, if I could see God, it would help me believe in him.’ I said, ‘Well, honey, the problem isn’t that you’ve never seen God. The problem is that you’ve never seen your mother.’ And her mother was sitting right next to her!
“My daughter said, ‘What do you mean, Dad?’ I said, ‘Suppose without hurting your mom, we were able to take her apart cell by cell and peek inside each one of them. We would never come to a moment where we would say, ‘Look—here’s what Mommy’s thinking about doing the rest of the day.’ Or ‘Hey, this cell contains Mommy’s feelings.’ Or ‘So this is what Mom believes about pro football.’ We couldn’t find Mommy’s thoughts, beliefs, desires, or her feelings.
“‘Guess what else we would never find? We’d never find Mommy’s ego or her self. We would never say, ‘Finally, in this particular brain cell,
there’s
Mommy. There’s her ego, or self.’ That’s because Mommy is a person, and persons are invisible. Mommy’s ego and her conscious life are invisible. Now, she’s small enough to have a body, while God is too big to have a body—so let’s pray!’
“The point is this, Lee: I
am
a soul, and I
have
a body. We don’t learn about people by studying their bodies. We learn about people by finding out how they feel, what they think, what they’re passionate about, what their worldview is, and so forth. Staring at their body might tell us whether they like exercise, but that’s not very helpful. That’s why we want to get ‘inside’ people to learn about them.
“So my conclusion is that there’s more to me than my conscious life and my body. In fact, I am a ‘self,’ or an ‘I,’ that cannot be seen or touched unless I manifest myself through my behavior or my talk. I have free will because I’m a ‘self,’ or a soul, and I’m not just a brain.”
OF COMPUTERS AND BATS
Moreland’s denial that the brain produces consciousness made me think of the debate over whether future computers can become sentient. I decided to ask him to weigh in on the issue—although his ultimate conclusion was never in doubt.
“If a machine can achieve equal or greater brain power as human beings, then some physicalists say the computer would become conscious,” I said. “I assume you would disagree with that.”
Moreland chuckled. “One atheist said that when computers reach the point of imitating human behavior, only a racist would deny them full human rights. But of course that’s absurd. Nobel-winner John Eccles said he’s ‘appalled by the naiveté’ of those who foresee computer sentience. He said there’s ‘no evidence whatsoever for the statement made that, at an adequate level of complexity, computers also would achieve self-consciousness.’
52
“Look, we have to remember that computers have artificial intelligence, not intelligence. And there’s a huge difference. There’s no ‘what it’s like to be a computer.’ A computer has no ‘insides,’ no awareness, no first-person point of view, no insights into problems. A computer doesn’t think, ‘You know what? I now see what this multiplication problem is really like.’ A computer can engage in behavior if it’s wired properly, but you’ve got to remember that consciousness is
not
the same as behavior. Consciousness is being alive; it’s what
causes
behavior in really conscious beings. But what causes behavior in a computer is electric circuitry.
“Let me illustrate my point. Suppose we had a computerized bat that we knew absolutely everything about from a physical point of view. We would have exhaustive knowledge of all its circuitry so that we could predict everything this bat would do when it was released into the environment.
“Contrast that with a real bat. Suppose we knew everything about the organs inside the bat—its blood system, nervous system, brain, heart, lungs. And suppose that we could predict everything this bat would do when released into the environment. There would still be one thing that we would have no idea about
: what it’s like to be a bat.
What it’s like to hear, to feel, to experience sound and color. That stuff involves the ‘insides’ of the bat, its point of view. That’s the difference between a conscious, sentient bat and a computerized bat.
“So in general, computers might be able to imitate intelligence, but they won’t ever have consciousness. We can’t confuse behavior with what it’s like to be alive, awake, and sentient. A future superintelligent computer might be programmed to say it’s conscious or even behave as if it were conscious, but it can never truly become conscious, because consciousness is an immaterial entity apart from the brain.”
Moreland’s choice of a bat for his illustration was an oblique reference to New York University philosopher Thomas Nagel’s famous 1974 essay “What Is it Like to Be a Bat?”
53
Thinking about life from a bat’s perspective prompted me to briefly pursue another line of inquiry on a tangential topic. “What about animals—do they have souls or consciousness?” I asked.
“Absolutely,” came his quick answer. “In several places the Bible uses the word ‘soul’ or ‘spirit’ when discussing animals.
54
Animals are not simply machines. They have consciousness and points of view. But the animal soul is much simpler than the human soul. For example, the human soul is capable of free moral action, but I think the animal soul is determined. Also, Augustine said animals have thoughts, but they don’t think about their thinking. And while we have beliefs about our beliefs, animals don’t.
“You see, the human soul is vastly more complicated because it’s made in the image of God. So we have
self
-reflection and
self
-thinking. And while the human soul survives the death of its body, I don’t think the animal soul outlives its body. I could be wrong, but I think the animal soul ceases to exist at death.”
Bad news, it seems, for the bat.
CONSCIOUSNESS AND EVOLUTION
Moreland had made a cogent case for consciousness and the soul being independent of our brain and body. “How does this present a problem for Darwinists?” I asked.
Moreland glanced down at some notes he had brought along. “As philosopher Geoffrey Medell said, ‘The emergence of consciousness, then, is a mystery, and one to which materialism fails to provide an answer.’ Atheist Colin McGinn agrees. He asks, ‘How can mere matter originate consciousness? How did evolution convert the water of biological tissue into the wine of consciousness? Consciousness seems like a radical novelty in the universe, not prefigured by the aftereffects of the Big Bang. So how did it contrive to spring into being from what preceded it?’ ”
Moreland looked squarely at me. “Here’s the point:
you can’t get something from nothing
,” he declared. “It’s as simple as that. If there were no God, then the history of the entire universe, up until the appearance of living creatures, would be a history of dead matter with no consciousness. You would not have any thoughts, beliefs, feelings, sensations, free actions, choices, or purposes. There would be simply one physical event after another physical event, behaving according to the laws of physics and chemistry.”
Moreland stopped for a moment to make sure this picture was vivid in my mind. Then he leaned forward and asked pointedly: “How, then, do you get something totally different—conscious, living, thinking, feeling, believing creatures—from materials that don’t have that? That’s getting something from nothing! And that’s the main problem.
“If you apply a physical process to physical matter, you’re going to get a different arrangement of physical materials. For example, if you apply the physical process of heating to a bowl of water, you’re going to get a new product—steam—which is just a more complicated form of water, but it’s still physical. And if the history of the universe is just a story of physical processes being applied to physical materials, you’d end up with increasingly complicated arrangements of physical materials, but you’re not going to get something that’s completely nonphysical. That is a jump of a totally different kind.
“At the end of the day, as Phillip Johnson put it, you either have ‘In the beginning were the particles,’ or ‘In the beginning was the Logos,’ which means ‘divine mind.’ If you start with particles, and the history of the universe is just a story about the rearrangement of particles, you may end up with a more complicated arrangement of particles, but you’re still going to have particles. You’re not going to have minds or consciousness.
“However—and this is really important—if you begin with an
infinite
mind, then you can explain how finite minds could come into existence. That makes sense. What doesn’t make sense—and which many atheistic evolutionists are conceding—is the idea of getting a mind to squirt into existence by starting with brute, dead, mindless matter. That’s why some of them are trying to get rid of consciousness by saying it’s not real and that we’re just computers.”
