Why Your Mind Cannot Be Your Brain

When I was a child, my mother used to look in at the clutter of room and exclaim, "How in the world can you leave your room in such a mess? Have you lost your mind?!" My mom's statement was hyperbole. She was expressing both disapproval with my living in a way that contradicts appropriate practice and bewilderment at why I would even want live in such a state of disarray. It simply made no sense to her how a teenage boy could say he cared for his things while treating them as such. Of course a lot of this was simply immaturity expressing itself through laziness. Today, it does not take a pole vault to get from my door to my bed.

However, I fear that our today culture is in danger of losing our collective minds. As I've stated before, we live in an age where science is lauded above all else. With the overemphasis on science comes a presumption of materialism—that is that the material aspects of ourselves are the only things that are real or they are the only things that really describe us and our actions. Neuroscientists scan the brains of serial killers, looking for some physical trace as to why those individuals would commit such heinous acts, even if the findings show that they themselves have the same physical traits as the killers!

The problem is that while modern scientists assume that brain scans are all we need to understand the mind, no one should make the mistake that the mind is the brain. The mind is something completely different than the brain and one can see that in several ways.

Mental states are fundamentally different than physical states.

First off, when we talk about the mind, we are referring to things called mental states. These include thoughts about something, experience, will or desire, intentions and things of this sort. A serial killer has intent to hunt and kill a victim even before he does so. After News Year's Day, many of us change our eating habits because we have an intent to lose weight, so we conform our actions to our intent. Notice that biologically, the drive to eat would make sense. We feel hunger. But our intention overrides that natural feeling and we curb our eating anyway.

Things like thoughts, ideas, desire, intention, and will are qualitatively different from brain states. A thought contains content that is not physical at all. Think of the sentence "I think, therefore I am." That sentence holds an idea, a concept that doesn't exist physically. If you are reading this on a computer right now, you cannot understand the sentence in the least bit if you were to measure its length and width on your screen. Neither will it help you if I explained the inner workings of my computer and told you how electrons traveled from my keyboard through my CPU, how data is stored on servers on the Internet and how it's delivered to your device. None of this tells you anything about the sentence, what it means, or whether its true. The idea is independent of the mechanism by which it is delivered. The idea is understood by the mind, regardless of how it was perceived by the senses and brain.

Because ideas are fundamentally different, we must recognize that they are not physical, and the same is true for thoughts, desires and other mental actions. It makes as much sense to say that my intent to lose weight rests 4.5cm from my right ear near my cerebellum as it does to measure the letters on your screen to understand a sentence. Mental states simply cannot be described using physical descriptors. That should be a tip off that mental states are fundamentally non-physical. The working of the mind, therefore, is not the same thing as the working of the brain. The mind is an immaterial aspect of a person. Thus, a person must be made up of material and immaterial components. That part of a man that is immaterial is the part Christians identify as the soul and the mind is one part of a man's soul.

In the rush of science to reduce knowledge to those things that are physical, they have run roughshod over the idea that the mind is distinct from the brain. Brain scans are supposed to tell you your thoughts, even though such a process is completely incapable of so doing. Such a concept bewilders me as much as my messy room confused my mother. It shouldn't be considered appropriate practice and I believe it reflects a level of ignorance and immaturity among its adherents.

A mind is a terrible thing to waste. Don't lose yours in the hype.

If We're Only Our Bodies, Life Is Meaningless

What is the thing that makes me me? I found an interesting comic on the Internet the other day that does a great job in unpacking one of the problems of the materialist position that all we are is the sum total of our physical makeup. You can read the whole thing here, (it's rather long) but I will summarize.

The comic depicts a day where science has finally invented a machine to transport objects instantly from one location to the other. Think Star Trek. Of course, everyone hails this great technological feat, but at least one man, the protagonist of the strip, is disturbed. The comic states:

The machines did more than transport people. They also killed them. Since the machines didn't use exactly the same atoms in exactly the same position, what arrived on the other side wasn't the original but only a copy. However, because the copy had the memory of the original's past, it believed it was the same person.

The man is disgusted at the wholesale death that people were accepting for the sake of convenience, which he deems immoral. He eventually meets the inventor of the machine and confronts him on such wanton disregard for human life. The inventor counters by answering, "My boy, surely you don't think that 'you' are the individual atoms of your body, do you? One carbon atom is the same as the next! And your body itself flushes out and replaces atoms all the time, yet you say nothing of copies. 'You' are not the atoms in your body but the pattern of the atoms." The man realizes now that every day he awakes his atoms are different. He dies every night as he loses consciousness and a copy wakes in the morning with the memories of the past. The man goes into an existential crisis.

The question of identity that the strip portrays is one that has a long history in philosophy, going back to ancient Greece. Known as Theseus' Paradox, it is usually represented as a ship piloted by Theseus whose weather-worn components are replaced one at a time until eventually there are no original parts. Is this still Theseus' ship? What if one were to take all those original pieces and reassemble them right next to the repaired ship? Which would properly be Theseus' ship now?

What is the Essential Element?

Both the transporter machine and Theseus' paradox ask the question of what makes up the essential element of a thing. If we are only a pattern of atoms arranged in a certain way, then can two specific identical patterns of atoms both claim to be the same person? The comic assumes that our material nature is really all there is to us. Our consciousness and our memories are what inevitably come from a specific arrangement of those atoms. That means the mental reduces to the material, and you can recreate a consciousness by duplicating the specific material components.

As the comic shows, if this is true then life can be seen to be meaningless. What one does doesn't matter since a real you doesn't continue through life, but a bunch of copies. When viewed through a materialist lens, there is really no meaning to life at all. However, Christianity offers an answer to this dilemma. The Christian view of humanity teaches that we are not merely the assembly of atoms. Human beings have not only a body but a soul, an immaterial aspect of ourselves that stays the same throughout our existence. The soul is not replaced bit by bit. It is fundamentally the same thing. The soul is our essential self. While humans are made to be both body and soul, it is in our souls where our conscious selves reside. Even when we sleep, our souls continue and we don't cease to be.

Implications of a Soul

The idea that each of us possesses a soul has incredible implications. It not only provides continuity in this life (I am the same person tomorrow when I awake and I am today), but it gives us an understanding that people who are born without things like arms and legs are still fully valuable as human beings because they do not have less of a soul. It helps us understand why unborn human beings are valuable individuals. It also helps us to understand that what we do in this life matters because even if our material elements are destroyed in death, our souls will continue on.

J. P. Moreland has quoted J. Gresham Machen who said, "I think we ought to hold not only that man has a soul, but that it is important that he should know that he has a soul." We can clearly see why it is so important. If we are to take the materialist position, we are entirely consistent to believe there is no meaning to anything at all and there's really nothing to live for. But because we are body and soul, God has given us real meaning for this life as well as for the next.
