In my first installment on the mind, I discussed the question, “what is consciousness?” One of theattributes of consciousness that I discussed was that of qualia (kwal’ ee ah) or the qualitative aspect of consciousness. I mentioned that these are the states that have an experiential or sensory nature to them. These sensations include sight, smell, taste, touch, and sound. Each sensation like a pain, an itch, a tickle, etc., is known as a quale (kwal’ ee).So far, it seems like this idea would be fairly uncontroversial, but it actually presents many challenges and has been rejected by some philosophers as nonsensical. These would be philosophers who hold a materialist (the world consists solely of particles in fields of force) or physicalist (the belief that all phenomena can be reduced to physical processes and properties). The question is whether there are phenomena that cannot be accounted for within a materialist or physicalist worldview. I believe that qualia is just such a phenomenon. Consciousness is different than qualia, however, consciousness, as I said earlier, has a qualitative aspect to it. NYU professor of philosophy, Thomas Nagel, presented an argument that has come to epitomize qualia in his “What it is like to be a bat” illustration. Nagel argues that if physicalism is true, then consciousness and qualia must be reducible to physical explanations; however, he believes that the subjective experiences that we have cannot be so reduced. Nagel asks us to think about a bat. Bats navigate by sonar, or echolocation. They send out signals that are processed by the bat’s brain to detect objects and to help it maneuver around objectsand to detect and capture prey. This is a bat form of perception, but it is completely different from human perception. Nagel adds, “there is no reason to suppose that it is subjectively like anything we can experience or imagine.” (1) Other bat behaviors include sleeping upside down, flying (with their own wings), eating rodents, etc. And yet, even if we could mimic these behaviors, it would only tell us what it is like for me to be a bat, not what it is like for a bat to be a bat. The problem is the same in reverse in that if there was a race of space aliens, let’s say, Martians, who possessed superior intellects to ours, it would be just as impossible for them to imagine what it would like for us to be us as it is for us to imagine what it is like for a bat to be a bat. Another illustration that makes a similar point was developed by philosopher, Frank Jackson, developed the illustration,“What Mary Didn’t KNow.” In this account, As the story continues, Mary is freed from her black and white cell to experience the world of color. She knows all there is to know about color, except what it is like to experience it. She actually learns something that she could not have otherwise learned or known unless she experienced it first-hand. Jackson argues that there is a type of knowledge that escapes the physicalist’s realm of knowledge. In other words, Mary could know all physical facts about the universe, but still learn new knowledge upon her release the entailed that physical knowledge is not everything there is to know. These two illustrations give an idea that qualitative experiences, or qualia, point us to a subjective aspect to ourselves that is not adequately accounted for in a purely physicalist or materialist accounting. There is a subjective aspect to us, a “what it is like to be me,” that points us to the idea that we are more than just the sum of our physical parts. There is much more that could be said about qualia, but this should give you a “feel” for what it’s all about. __________________________________________________________ (1) Thomas Nagel, “What is it like to be a bat?”, The Philosophical Review LXXXIII, 4 (October 1974), 436.

Mary is confined to a black-and-white room, is educated through black-and-white books and through lectures relayed on black-and-white television. In this way she learns everything there isto know about the physical nature of the world. She knows all the physical facts about us and our environment, in a wide sense of 'physical' which includes everything in completed physics, chemistry, and neurophysiology, and all there is to know about the causal and relational facts consequent upon all this, including of course functional roles. If physicalism is true, she knows all there is to know. For to suppose otherwise is to suppose that there is more to know than every physical fact, and that is just what physicalism denies. (2)

Let us begin by examining the question, what is consciousness? Although there is no definitive and exhaustive answer as to what consciousness is, we have some ideas as to what consciousness is like. Van Gulick1 describes several elements of consciousness, including:
- Sentience - the capability to sense one’s environment.
- Wakefulness - being awake and alert.
- Self-consciousness - being self-aware.
- What it is like - Thomas Nagel described this as “something it is like” to be who you are. The subjective aspect of being who you are.
- Subject of conscious states - having conscious mental states
- Transitive consciousness - the ability to be aware of many things at the same time or one thing over time.
- States one is aware of - the awareness of having states of awareness or of conscious states. These are also known as meta-mentality or meta-intentionality.
- Qualitative states - otherwise known as qualia, these are states that have an experiential or sensory nature to them. Whenever we have a sensation (sight, sound, feel, taste, or smell), these are known as quale (kwal’ ee).
- Phenomenal states - the totality of qualitative states forms the phenomenal state of consciousness.
- Access consciousness - This concept was developed by Ned Block and describes not the phenomenal state, but whether the sensory information can be accessed to guide the organism.
- Narrative consciousness - this is more commonly known as the stream of consciousness and refers to the ongoing serial of episodes that string together to the perspective of the self.
Philosopher, David Chalmers wrote:
Consciousness poses the most baffling problems in the science of the mind. There is nothing that we know more intimately than conscious experience, but there is nothing that is harder to explain. All sorts of mental phenomena have yielded to scientific investigation in recent years, but consciousness has stubbornly resisted. Many have tried to explain it, but the explanations always seem to fall short of the target. Some have been led to suppose that the problem is intractable, and that no good explanation can be given.2
Chalmers breaks the problem of consciousness down into the “easy problem” and the “hard problem.” The easy problem is that part of consciousness that can easily be explained by cognitive science, while the hard problem “seem to resist those methods.”3 The easy problems are those of categorizing, discriminating, reporting mental states, attention, behavioral control and other like phenomena. The hard problem deals with issues that are more subjective, like qualitative experience, or as Thomas Nagel described, the what it is like phenomenon. In other words, there is something it is like to be me or a bat or a my dog. These are subjective experiences. We have others as well, including what it is like to listen to Bach, or to eat Jambalaya, or to watch the Packers win the Super Bowl. Each of us will have a different experience in each of these cases. In later posts, I will give more detail on this problem and some of its implications.
Consciousness is an intriguing study and often quite perplexing. Many philosophers over the years have attempted to explain consciousness or, at times, explain it away; at least, various aspects of it. In the coming weeks I will explore many of these aspects, describing how the many of the philosophers have attempted to fit them into their respective worldviews. I will look at what I believe to be the best explanation of consciousness and the phenomena associated with it. I hope you will read on and gain greater understanding of this fascinating field of study. Leave me comments and questions along the way.
Can Science and Religion Peacefully Coexist?
Posted by Thinking Eternally at Tuesday, October 12, 2010
University of Chicago professor of biology, Jerry Coyne, recently penned an article that appeared in USA Today entitled, Science and religion aren't friends. In it, Coyne made the argument that "science and religion are fundamentally incompatible." He cited the several books by New Atheists authors such as, Richard Dawkins and Sam Harris which he says have exposed the "dangers of faith and the lack of evidence of the God of Abraham." I'm not sure what this has to do exactly with his argument that science and religion are incompatible, since these are not science books, but rather deal mainly in philosophy, but we will set that aside for now.
Of course, Coyne acknowledges that there are leading scientists who are Christians; however, he simply writes that off as those who hold "conflicting notions in their heads at the same time." He compares this to making a case, based upon the rate of infidelity, that monogamy and adultery are "perfectly compatible." However, he says, it is important to distinguish real truth from that which we only want to be true.
As for the number of scientists who are atheists, it is easy to cite statistics of the number of people who believe one idea or another, but statistics don't determine truth, they only determine popularity, and truth is not a popularity contest. Nor can one assume the truth of macro evolution, which is far from solid science (not to be confused with micro evolution which is solid), and then criticize a group of people who don't agree with it, even if their reasons are not grounded in scientific arguments. This doesn't make them necessarily wrong, nor does it do anything to prove his thesis.
For many years now I have spent a significant amount of time speaking to college students at campuses around the Chicagoland area. What I love about speaking with college students is they are in an environment of idea exchange and they enjoy engaging in thought provoking conversations. I often ask students where they find meaning for their lives and I often get answers in a similar vein; they usually tell me that meaning is wrapped up in what they will do with their lives or with whom they associate. That is the answer of a practical existentialist (whether they know it or not).

What is True and Can We Tell? Reflections on Inception
Posted by Thinking Eternally at Wednesday, August 11, 2010Which is more difficult, to awaken one who sleeps or to awaken one who, awake, dreams that he is awake? --
Søren Kierkegaard, Works of Love (1847)
These words, though written more than a century and a half ago, could have been written about Christopher Nolan's latest movie, Inception. This movie, if you have not yet seen it, is a labyrinth of dream sequences of different levels into which the main character, Dom Cobb (Leonardo DiCaprio) enters with his team to implant a thought into the head of Robert Fischer (Cillian Murphy) so that he will break up the oil empire that his father is set to leave him upon his imminent death.
Cobb, an architect by training, left the world of designing buildings to enter the world of designing dreamscapes. He develops his skills to not only extract information from people by entering their dreams, but to also implant ideas, leaving no trace of his having done so. Cobb is approached by Fischer's competitor and enticed by the offer of being able to return to his home and kids from whom he had been estranged due to legal troubles. To do this, he must go into the consciousness of Fischer through his dreams and continue going deeper and deeper into those levels of his consciousness until he can implant the thought without leaving evidence of his having been there.
In the end, Cobb's pursuit led him back to the relationship with his children (if you believe that, in the end, he was not still caught in a dream state), and that is a good pointer to the ultimate relationship to which we are called, but only a pointer. One of the benefits of human relationships is to point us to a still greater relationship, the relationship with God through Jesus Christ. The Apostle Paul says, "now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known." (1 Cor. 13:12) That is the truth we are called to pursue.
You are probably looking at the title and asking, "what are you talking about?" Well, this topic came up during a discussion I am involved in on my local college campus. We've been discussing the idea of telos for some time now. For those not familiar with the word or the concept, telos means end, purpose or goal. In other words, when the author of the Westminster Shorter Catechism asked the question, "What is the chief end of man?" he was asking, "What is man's telos or purpose?" The pursuit of meaning has been, I believe, one of the oldest pursuits of man. So, your asking, what does the title of this blog post have to do with this discussion of telos? Let me explain. The question was asked whether we could tell what a thing was by how it was made. In other words, can we describe a thing, its composition, its features and make up, and determine what it is? Let's use a hypothetical to try to illustrate. Suppose an alien craft was passing by our planet and something fell off and landed in such a way that it remained completely intact and undamaged. Suppose also that this object was something that we had never seen, made from a material of which we were completely unfamiliar. In other words, it is a completely foreign object to our observers, scientists and philosophers. Our researchers would take pictures of it, try to determine what it is made from, and try to determine its function. Let's also suppose that they were able to reduce the material make up to its base elements, all of which were common to the universe, even though the final make up of those elements was unfamiliar (I am supposing that the aliens had some technique to uniquely change the structure of these materials into a unique finished material for the sake of this illustration). So, we could determine what its make up was, its shape, size and weight, but would that tell us what it was? No, I don't think so. In essence, we would need to know the intent of the designer to know what it was and what its function was. In other words, we could not determine a "what" from a "how". Sometimes, I feel like that is what many are trying to do today. We look at evolutionary theory and theories are constructed as to how some creature developed, or even, some feature of the creature. But, does that description, even if it is valid, determine what that thing is? If we knew nothing else about the feature or the creature, like the foreign object from the alien craft, would merely describing its make up and development determine its telos? I don't think so. Now, suppose we are the product of purely natural processes, how would we determine our telos, or would we even have a telos? I don't think that natural processes determine telos. Telos always seems to come from the mind of a designer. Machines obviously don't think and don't determine their own purpose. If we are merely glorified machines, I don't know why it would be any different for us. In fact, I am not sure what it would mean to determine one's own purpose and if it could be done, why any purpose, say being an evil dictator, would be any worse or better than determining that you were going to help the poor. After all, given the scenario that one determines his or her own purpose, who could say that the one that he or she chose was wrong. I don't see that a how could determine a what. I think that the chief end of man must be determined by the one who designed up and designated our purpose. He has revealed that the chief end of man is to glorify Him and enjoy Him forever.
The Fatal Flaw in Double Blind Prayer Experiments
Posted by Thinking Eternally at Friday, July 16, 2010We have all likely seen the reports on these "double blind" prayer experiments. The idea is to test whether prayer "works". Here is how these experiments work. First, a group of people with longer-term illnesses is identified, usually these people are hospitalized so that results can be tracked. Next, a group of people is identified to pray for these ailing people.
These types of studies, in addition to trying to determine whether prayer works, have been used as evidence for and against the existence of God. The U.K. radio program, Unbelievable?1, recently featured a discussion between U.S. atheist and professor of physics, Victor Stenger and British Christian and statistician, David Bartholomew on the issue of whether double-blind prayer studies prove or disprove the existence of God.
Bartholomew took the same position that C.S. Lewis took during his lifetime, that these studies prove nothing regarding prayer or the existence of God. Gregory and Christopher Fung quote Lewis as saying, "The trouble is that I do not see how any real prayer could go on under such conditions...Simply to say prayers is not to pray; otherwise a team of properly trained parrots would serve as well as men for our experiment."2
One of the most recent of these studies, conducted by the Harvard Medical School, was The Study of the Therapeutic Effects of Intercessory Prayer (STEP). The study, conducted over 10 years, with the cost of $2.4 million, produced the kind of results that C.S. Lewis would not have been surprised to see. This study included over 1,800 patients with heart conditions requiring surgery. The patients were divided into three groups: one group knowingly received prayer from a group of Chrisitans; the second and third group were told that they may or may not receive prayer; with one receiving prayer and the other not. The first group for whom prayers were offered to their knowledge, actually did worst of all, followed by the group that didn't know that they were receiving prayer but actually did. The group that did the best was the one for whom no prayers were offered by the research prayer group.
The researchers were actually not surprised by the results as they suspected that the first group might have felt pressure to get better knowing that prayers were being offered. Evangelicals have offered other reasons for the results, such as that many of those who didn't receive prayer from the research prayer team probably did receive prayers from family members and friends. However, I would like to add another idea to the mix.
Even though these are double-blind experiments, there are actually three parties involved, and the third party cannot be blinded to the study. Of course, God is that third party and God is fully aware of what is going on in these experiments. Victor Stenger asserted on the radio program that God would want to answer prayers for those who are sincerely seeking him, he would want to make himself known. Stenger argues that a God who hides himself cannot exist. He says that a good God, a moral God would not deliberately hide himself from people who are open to the possibility of his existence. Stenger says that given positive results of this type of prayer study he would immediately return to the church of his youth, the Roman Catholic church.
I have a few things to say about this argument. First, I don't believe that God hides himself from his creation. The Apostle Paul tells us in the first chapter of the Book of Romans that "what can be known about God is plain to them, because God has shown it to them." (v. 19) Paul explains that God's "invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they [we] are without excuse." (v. 20) This hardly seems to be describing a God who "hides" himself. On the other hand, I do believe that God keeps an epistemic distance from his creation so as not to force us to believe, and this may be to what Stenger is actually referring.
The main issue is that God is not necessarily interested in our believing that he exists. What, you ask, God doesn't want me to believe that he exists? That is not what I am saying. God could make it very clear to all creation that he exists in any number of ways. But, what would that accomplish? He would have a world of people at a point in history who know he exists; however, would that mean that he would necessarily have more people who trust in him? I don't think so. In fact, many would come to resent God forcing himself upon his creation.
Suppose that the government came along and decided that they would choose who your spouse was going to be, do you think that the knowledge of your intended spouse's existence and selection would cause you to love him or her? No, in fact, many would resent being told who to marry and many would resist that union. So why, given the irrefutable knowledge of God's existence, would it lead Victor Stenger or anyone else to love and trust in him? People, especially Americans like Stenger, don't like being bullied, and that is just how many would take this kind of imposition of God into the lives of his creation.
I, like the Apostle Paul, think that there is enough evidence for God's existence for those who are open to honestly considering that evidence. I think that the evidence is quite good for God's existence and am laying out some of those evidences this Summer in a class that I am teaching. However, this same evidence is rejected by people every day. In other words, God is not going to force the issue, but he is willing to make himself known to those who diligently seek him out.
So, let's scrap these prayer experiments and remember that God is not a cosmic vending machine. We cannot simply put in our prayer token, push a button and look for that packaged answer to prayer. God is a person who is fully aware of what is going on with these studies and what impact would come from giving positive results. It is interesting that these studies sometimes do produce results that some interpret to show that prayer "works," yet still, unbelievers make excuses as to why the study was flawed. So, I would beg to differ with Dr. Stenger and say that no matter what the results, it won't change in what a person puts his or her trust. It may make them more likely to pray, but not more likely to trust in the God who hears those prayers.
