The Mysteries Of Mysteries
Friday, November 30th, 2007For materialists, human consciousness is simply a matter of physics and chemistry. In their worldview, God is not needed to produce self-aware beings. They claim that if enough hydrogen atoms bang into each other for a long enough time, they eventually will produce an atheist. The above statement may seem facetious, but it is literally a correct conclusion from materialist reasoning.
In August, Discover Magazine ran a most intriguing article entitled, “10 Unsolved Mysteries of the Brain.” If you stop to ponder any of these mysteries deeply, it should give you goose bumps. The authors of the article observe that “Of all the objects in the universe, the human brain is the most complex.” They go on to enumerate the ten deep mysteries listed below that have confounded researchers about the three pounds of mostly fat that sit inside our skulls.
1. How is information coded in neural activity? We know that brain cells produce brief electrical discharges. These discharges appear to carry information, but as of yet no one has been able to determine if this information is digital or analog or how it is coded; nor is it certain that these voltage spikes carry information.
2. How are memories stored and retrieved? Memory storage is bizarre enough, but how it is retrieved is even more mysterious. Everyone has had the experience of being unable to remember something, and after giving up searching our memory, the information will later just pop up as if an unidentified file clerk had been sent out to the archives to look up the information and has finally come back with it. How does that work? What is doing that search?
3. What does the baseline activity in the brain represent? At rest, the brain, which only constitutes about 2% of the body’s mass, uses 20% of all the oxygen. This causes it to put out huge amounts of heat, but what is it doing with all of this energy when it is at rest? No one knows.
4. How do brains simulate the future? How is it that the human brain can play chess as well as the world’s best super computers? These computers can consider the outcomes of millions of moves per second, yet the human brain is just as capable of projecting the possible outcomes?
5. What are emotions? Feelings are a total mystery. They are so powerful that occasionally they can even kill the body, yet we have no clue as to what they are or how they are formed.
6. What is intelligence? This has proven a particularly intractable mystery, especially when the phenomenon of “idiot savants” is considered. The field of Artificial Intelligence (AI) has come to a complete halt. The optimistic prediction of the 1960s that robots would soon be doing all the work for us has given way to the reality we all face of having to spend lots of time on the keyboard doing even the simplest of tasks because computers are exactly as smart as door stops.
7. How is time represented in the brain? This is a multifaceted mystery. The brain seems to have many different clocks that enable it to do many different things. For example, the brain synchronizes the perception of external events such as vision and hearing so that we experience them simultaneously even though they are not perceived simultaneously. It is a nice little trick the brain plays on us to make reality seem more coherent.
8. Why do brains sleep and dream? While it is known that sleep deprivation can cause insanity and even death, we still have no clue what the brain is really doing during those hours when the body is mostly off line.
9. How do the specialized systems of the brain integrate with one another? Signal transmission in the brain’s axons is painfully slow at 1 foot per second. This is only one hundred millionth the speed at which your computer transmits signals, yet the brain coordinates the vast array of sensory inputs and outputs such as sight, memory, and body movement almost instantaneously. How in the world is this being done? Just think about that the next time you try to get your computer to multitask.
10. What is consciousness? This is truly the biggest question of all. How can three pounds of fatty meat be self-aware?
Why This Is Important
Despite the author’s optimistic expectations about the future of brain research, the ten unsolved mysteries listed above are just as mysterious today as they were 2000 years ago, 100 years ago, 50 years ago, and 10 years ago. Materialism makes a profound philosophical error in concluding that consciousness comes from the physics of the brain. As Sir John Eccles, a Nobel Lauriat in Medicine and Physiology, once put it, “Looking for consciousness inside the brain is like looking for the actors inside of your TV set.”
