Stephen M. Barr, a professor of physics at the University of Delaware, wrote Matter Over Mind at First Things. Origins generally evoke thoughts of life's origin or perhaps cosmology but the origin of consciousness is a challenge to both intelligent design and critics of the concept. Barr provides a brief summary about what we have learned:

Here is a small sampling of the things that have been learned so far: Different parts of the language center of the brain are used to understand speech and to formulate speech. Our brains analyze facial expressions differently from all other visual data in a specialized part of the temporal lobe called the “fusiform face area.” Different kinds of moral dilemmas (for example, ones that involve accidental versus deliberate harm to others) activate different neural circuitry in our frontal lobes. The parts of the limbic cortex that register the bodily responses associated with social emotions such as empathy and shame are connected by exceptionally long neurons to the regions of the brain where higher mental faculties are based. These special “von Economo neurons” are almost unique to human beings, and it has been suggested that this linkage is what allows us to reflect on and understand our own emotions and those of others and so to be more “deeply social” than other animals.

At his blog Thinking Christian Tom Gilson posted the blog entry The Will to Power–Is “Free Will” All in Your Head?: Scientific American. The link to the SA article is here. The author Christof Koch begins by posing the question: which part of the brain relates to behavioral decisions? He provides the qualifier- if it is the brain. Then in referencing the soul he adds the simile- like Casper the Friendly Ghost- which is sure to endear him to the scientific Ubermensch whose evidence of their status is a penchant for ridicule.

Herr Koch, we know the tune. It's nothing so primitive as a soul. No, volition springs forth magically emerges. Take a rain check on the specifics and don't think of inserting anything but confidence in materialist outcomes into the gaps of knowledge. The author then dishonestly describes dualism as emotionally reassuring. Even lower level Ubermensch know that only IDiots believe in dualism and that it is anything but emotionally reassuring. In the best Teutonic tradition Koch wants to know what laws Casper follows. There must be rules that describe volition. But if there are is it really free will? Take in a doubleheader and another rain check. The games will be played in a gap.

Roger Penrose has indicated that the conscious brain is explained only by a theory of physics we do not yet possess. That in turn would indicate that core elements of Intelligent Design i.e. purpose and volition, are undefinable by referencing any existing physics theory. Empirical disciplines like forensic science, archaeology and psychology utilize purpose and volition to derive conclusions based on physical evidence. Purpose and volition were revealed by human sources i.e. they were directly communicated or inferred through behavior. Whether derived through communication or observed behavior, effects of purpose and volition are manifestations of prior machinations of conscious minds. The workings of these minds are linked to brain cell activity. Although cellular functions are individually definable there is no theory citing a threshhold level of multi-cellular interactions at which consciousness kicks in and below which it does not exist.

Kauffman on the Philosophy of Mind is a short Technology Review article discussing views of theoretical biologist, Stuart Kauffman. This is from the article:

The gist of his answers is that mind is a quantum phenomenon that produces a classical output that Kauffman says is the source of free will. He adds that this classical output is nonrandom and yet cannot be described by the laws of physics because, as the quantum system decoheres, information is lost in a way that can never be retrieved.

If true, that's important because "if the quantum-classical boundary can be non-random yet lawless, then no algorithmic simulation of the world or ourselves can calculate the real world, hence the evolutionary selective advantages for evolving consciousness to "know" it may be great".

Recently TT member aiguy posted a well thought out comment which raised broader issues applicable to ID. His last paragraph states:

I think what is most interesting in this forum is to work on what aspects of the mind/body problem are relevant to telic theories of origins, and what the entailments actually are. In my view, telic theories require that cognition transcends physical causation – after all, you and various ID proponents (Dembski, Egnor, etc) often defend mind/body dualism. Do you agree that unless dualism is true, ID makes no sense?

The study of dualism is a major endeavor so I'll provide a shorthand version applicable to the mind/brain issue. Although the mind and brain are clearly interdependent in my view there is a distinction between the two. You don't have to be a dualist to realize the distinction has practicle utlity. The mind is something we exercise and experience on a daily basis. Like gravity its effects are continually evident. That was also the case prior to the advent of advanced technology. Humans have always had evidence of minds and the means to assess minds and intelligence.

By contrast neurobiology is very recent. We are able to learn how specific biochemicals influence thinking and emotions. We also are able to observe how thoughts and emotions can alter neural biochemistry. Distinguishing between the mind and the body tissue associated with its function makes as much sense today as in prior eras.

13 things that do not make sense or do they? Take the first one:

1 The placebo effect
Don't try this at home. Several times a day, for several days, you induce pain in someone. You control the pain with morphine until the final day of the experiment, when you replace the morphine with saline solution. Guess what? The saline takes the pain away.

This is the placebo effect: somehow, sometimes, a whole lot of nothing can be very powerful. Except it's not quite nothing. When Fabrizio Benedetti of the University of Turin in Italy carried out the above experiment, he added a final twist by adding naloxone, a drug that blocks the effects of morphine, to the saline. The shocking result? The pain-relieving power of saline solution disappeared.

So what is going on? Doctors have known about the placebo effect for decades, and the naloxone result seems to show that the placebo effect is somehow biochemical. But apart from that, we simply don't know.

But the placebo effect makes perfect sense. It's just that it runs counter to mainstream thinking. The mind interacts with but is independent of brain cells. That's why beliefs can alter brain cell function. A straightforward and rational interpretation consistent with facts. But the problem with it is it leaves Lewontin's door a bit open. But he'll survive along with the rest of you.

Peter S. Williams's A Rough Guide to Creation & Evolution contains this:

My first piece of advice is to start at the very beginning, with just the first five words of Genesis: "In the beginning, God created…" If you need more words to get your teeth into, go to John 1:1-3: "In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made." "Word" is a translation of the Greek term Logos, from which we get the word logic. Logos is equivalent to what scientists like Stephen Hawking mean when they talk about "knowing the Mind of God". The belief that Logos came first, that Mind created Matter, is the fundamental theistic claim about creation, and this is the place to start when considering the relationship between Creation and Evolution.

Plato noted that "all things do become, have become and will become, some by nature, some by art, and some by chance" (The Laws, book X), and he argued that either Mind comes before matter (and the world is basically a work of art), or matter comes before mind (and the world is purely the result of chance and natural regularities). The doctrine of Creation says that Mind came before matter – the cosmos is a creation, a work of art.

In a recent comment TP wrote:

In an attempt to stay topical, it is my position that Penrose's argument against "Strong AI" procludes the "intelligence is algorithmic" presumption.

I maintain that the only way AI can have consciousness is if it includes Quantum Mechanics (which is not algorithmic).

Ryan Sayre Patrico authored The Human Brain is a Machine at First Things. It's a short piece:

At least, that what atheist philosopher Daniel Dennett thinks. He argues that “we’re robots made of robots made of robots made of robots.” In other words, the brain is made up of millions upon millions of neurons, and each of those neurons is made up of eukaryotic cells, and each of those eukaryotic cells is made up of organelles, and each of those organelles is made up of proteins, and each of those proteins is. . . well, you get the idea.

Dennett then goes on to say that the sheer complexity of the human brain makes it nearly impossible to create a humanoid robot—that is, a robot with human-like intelligence. So, “we’re robots,” but robots aren’t us. Hmm. . .

And robots, as I understand it, don’t have free will. An absence of the will is what makes them robots. If that premise is true, and if Dennett is correct in saying “we’re robots,” I can’t for the life of me understand how he can talk about changing his mind when he thinks he made a mistake.

I guess when Dennett says “we’re all robots” he really means “everyone, that is, except me.”

Why would the complexity the human brain make "it nearly impossible to create a humanoid robot—that is, a robot with human-like intelligence?" I would think the existence of suitable technology would make a deliberate developmental process more likely than one with a largely stochastic generating basis.

Over at Uncommon Descent, Denise O'Leary posted a thread on Phineas Gage that I thought was worth looking at. I know I was taught that Gage's brain injury changed his personality. I'm sure many others here have heard the story. To find out that it probably wasn't true is quite a revelation.

Michael Egnor wrote Materialism of the Gaps at Evolution News & Views. Quoting Egnor:

I must say that I’ve never understood the rhetorical force of the ‘God of the Gaps’ argument. The God of the Gaps sneer is invoked to imply the inexorability of materialism as a complete explanation in natural science. Any critique of materialist dogma in science from a design or immaterial perspective is derided as a 'God of the Gaps' argument. But the real issue is the gaps, which are plentiful and very wide.

Egnor puts his finger on the real issue. Perhaps he does not understand those attracted to the phrase because he does not perceive the mindless, robot-like mentality leading one to fall back on cliches. More from Egnor:

Tom Gilson has a blog entry titled Knowledge and Bias: A First Response to Tom Clark One striking aspect of the exchange between Tom Gilson and Tom Clark is its substantive dialog and the civil nature of it. My focus is a small part of it, specifically a portion of a comment made by Tom Clark. The first quoted comment segment:

That prediction doesn’t stem from a naturalistic bias, but from the nature of science and more generally the project of gaining intersubjective knowledge: understanding things and their connections tends to unify our view of the world, and the world that science reveals is what we ordinarily call nature. I also say that “Should something categorically immaterial someday play a role in scientific explanations, so be it, but for the time being there’s no indication that dualism will carry the day.”

In writing Quantum Enigma: Physics Encounters Consciousness, authors Bruce Rosenblum and Fred Kuttner seemed to have two goals. First to provide an honest, straightforward understanding of the fundamental aspects of the quantum world as opposed to the classical world. Second, to graciously and even-handedly explain why these aspects both seem to 'encounter consciousness' and why, despite this, there is a strong tendency for physicists to prefer the matter remain downplayed – if it needs to be mentioned at all.

They've succeeded. What's more, their book is uniquely useful not only to better understand what could be called the foundational weirdness of quantum physics (and in a way pleasantly free of overt mysticism or exaggeration) but also to get a glimpse of what happens when scientific research doesn't return results friendly to the reigning metaphysics.

Shallow analysis is a common bedfellow of attempts to link science to stealth metaphysics. The stealth metaphysics considered here is the issue of free will. Denialists- materialists who maintain that free will is but an illusion- on occasion invoke a study showing brain activity in a specified brain region prior to the moment an individual expresses a decision. Patterns of brain activity consistent with the choice made can be evident seconds prior to the moment an individual actually commits to a decision. That data is used to support the contention that physical brain dynamics, preceeding a decision, determine the decision and allow the individual to falsely think that he or she has chosen between available options.

So what's wrong with the preceeding analysis? One striking aspect of denialist thinking is its vagueness. We have no neural mappings allowing us to distinguish between opting for a banana instead of an apple. We lack the details needed to link pre-decision process thinking to precise brain conditions. Materialists will assert that desires and decisions are reducible to states of a physical system. But they lack detailed knowledge not just of the range of possible relevant physical states, but also of the thoughts correlating to different physical states. Free will denialists all too frequently mask their metaphysics in sciency garb.

Michael Egnor wrote Consciousness and Intelligent Design which appears at Evolution News & Views. From his article:

"Lawful dependence" in science has always been restricted to correlations between manifestations of third-person objective ontology. Lawful dependence correlates things. The correlations are generally quantitative, described by mathematics. A moving magnet (third person ontology) induces electrical current (third person ontology), in accordance with Maxwell’s equations.

Egnor gives us a glimpse of what a brain/mind model would indicate. When x induces biochemical cascade y in a specified area of Jason's brain, Jason communicates in his second language- Spanish. Happens every time for reasons unknown to researchers. Researchers also discovered that Jason's word choice consists of about three times more words prone to be utilized when he is angry (insults, curses, trash talk etc.) than when he normally speaks Spanish. The words correlate to vital signs consistent with the anger emotion.
