The Problem of Free Will III: The All-Knowing God  

In the previous two posts we established that we are conscious beings who are have Free Will within the constraints of being human in this universe. Indeed, the purely materialistic argument is that Consciousness and Free Will arose human populations because they enabled us to gain survival benefit from behaviors that are unpredictable and more complex, creative and powerful than pre-determined reflexes. The atheist/materialist is thus forced to argue in favor of Free Will, rather than against it.

But the atheist/materialist points out that Free Will is incompatible with the usual notion of an Omniscient (All-Knowing) God. If God knows the Future, then the Future is pre-determined. If God does not know the Future, then God is not All-Knowing. And the atheist would be right, if the Graeco-Roman categories of Omniscience, Omnipotence, and Omnipresence were categories that circumscribed the Deity.

Here I side with the Muslims, when they say, "Allahu Akbar!" which means, "God is greater!" Greater than anything you can imagine, including your philosophical categories. But before we dismiss the argument with a slogan, let us consider an alternate reality that you alone control.

Let us consider your dreams. You are the Creator of every one of them. You yourself are Omniscient, Omnipresent, and Omnipotent with respect to your dreams. Part of you must know how each one will turn out, because part of you creates and controls the plot. But you are still surprised at what occurs in your dreams. Except for relatively rare instances of "lucid" dreaming, you feel out of control, swept along by the current of events in the dreams that you dream up.

Elsewhere I have argued that the Universe and everything in it seems like one vast, self-consistent dream in the Mind of God. Given that we are made in the "image" of God, perhaps it is not too outrageous to wonder if God experiences something of the same surprise at God's own dreaming of this Universe?

And why should God be limited to only one dream?

The Problem of Free Will II: Limited Autonomy  

Let us return to the first proposition of my friend the skeptic:


"Every human thought is in principle a pre-determined consequence of biochemical processes that are themselves determined by evolution, the course of which is pre-determined by chemistry and physics. Therefore, there is no such thing as free will."

At first, it appears that the question of Free Will is an "either/or" proposition. Either we have Free Will, or we don't. What we actually experience, however is freedom within the constraints of our abilities. For example, you may be free to desire whatever you can imagine, but you are not free to desire what you can't imagine. The limits of your own imagination are the limits of what you can want, or will. I concede that the limits on our Free Will are pre-determined by our genetic makeup combined with our experience and our situation in the world. But within those limits, determinism is dead.


Determinism is based on the notion that if we could know the positions and velocities of every particle in the Universe we could, in principle, calculate the entire future evolution of the Universe. This idea was born from the structure of Newton's equations of motion and held sway for over 200 years, until the 1920's. Then we found out that very small particles begin to exhibit behavior that is masked by the sheer size of large ones. It turns out that the process of precisely measuring a particle's position destroys information about its velocity, and vice versa. That is to say, measuring exactly where a particle is gives it such a whack that we can no longer know where it's going, and measuring exactly where it's going can only be done via interactions that "smear out" where it is. That the position and velocity of a particle cannot simultaneously take on precise values is a statement of Heisenberg's Uncertainty Principle, and seems to be a fundamental limitation on the measurability of reality.

If the Uncertainty Principle struck Determinism a mortal blow in the 1920s, nonlinear dynamics delivered the coup de grace in the 1980s. The nonlinear dynamicists finally had the desperation, the courage, and the methods to tackle some of the really hard problems of Classical Mechanics (the branch of physics that deals with the motion of ordinary sized things and is described by Newton's equations). They found that even for relatively simple systems, like three bodies moving under mutual gravitational attraction, the future motion can depend so sensitively on the given conditions at any moment (positions and velocities) that the detailed motion of the system is unpredictable (or chaotic) - not only because classical measurements are only finitely precise, but because of the limitations imposed by the Uncertainty Principle as well. In other words, the Universe is not nearly as well-behaved as a wind-up clock. The Universe is not a machine or a mechanism, as we understand machines and mechanisms. Determinism is dead.


How dead is it? Consider that three bodies moving under their mutual gravitational attraction have 6 degrees of freedom per body (their positions along any three perpendicular directions in space, and their velocities along those directions). These three bodies are a system with 18 degrees of freedom whose motion is unpredictable in principle. Now consider that the human brain has about 100 billion neurons, each with about 10,000 interconnections to other neurons, each of which is a degree of freedom for that neuron. The human brain is a system with at least a quadrillion degrees of freedom. The idea of trying to predict the state of a living human brain is ludicrous. 


And that's just classically. Quantum mechanically, the wave function of each neuron in your brain extends throughout the whole universe. True, the far reaches of that wave function have very low values. But I include it to emphasize the fundamental impossibility of knowing all the influences on the state of the brain. 

Now the three gravitating bodies will under certain circumstances, stay within some enveloping region of space. Within that region, it is impossible to predict where they will be over the long term. But they will be (almost completely) somewhere within that region. They are free within that constraint.

Similarly, you are free to think and to desire whatever you want within the constraints of your being human at a certain time and place. That is to say, you have Free Will within limits. You are free to will anything possible. You are free even to will the impossible. But you are not free to will the unimaginable, because you don't know what it is. This is Limited Freedom, rather than an Absolute Freedom. The limits are set only by human nature and physical reality. At least, until we figure out how to change them.

So the dichotomy between Absolute Freedom and being an automaton is false. There is space for freedom with the constraints of being in this Universe. It puts us in a situation that seems paradoxical to absolutists who insist on Free Will as an all-or-nothing proposition. As Isaac Bashevis Singer once said, "We have to believe in Free Will. We have no choice."

The Problem of Free Will I: Is anybody there?  

"Every human thought is in principle a pre-determined consequence of biochemical processes that are themselves determined by evolution, the course of which is pre-determined by chemistry and physics. Therefore, there is no such thing as free will. In fact, there is no such thing as consciousness. What appear to be sentient beings are just automata that give the illusion of consciousness."

I feel frustrated, even enraged when I hear or read statements like this, whether from scientists and non-scientists. Such a statement is equivalent to saying that the Universe and everything in it is dead — even ourselves. It implicitly permits the most outrageous disregard of everything and everyone, even one's one children. After all, what harm is there in neglecting or even killing that which never was, and never could be really alive?

I'm outraged when people make such statements, because it is that easy and that quick to show that such statements would have grossly immoral consequences, were people to take them seriously. I'm frustrated when people make such statements, because they are wrong. For the rest of this thread, I would like to show you why.

Let's start with basic philosophy. To whom do automata give the illusion of consciousness? This is not just a semantic game. An illusion cannot have itself, nor can an automaton have one. The very idea of an illusion pre-supposes the idea of consciousness on the part of someone. That is, you must be conscious in order to have the illusion (the false awareness) that you are conscious. You might be semi-comatose and in a dream-like state, but that is still a state of consciousness. In fact, consciousness is the prime datum of philosophy, both Western (self-awareness as in Descartes' "I think, therefore I am") and Eastern (a generalized oceanic awareness).

Consciousness is also the prime datum of science. The discipline of science is to get ever more precise and accurate data into one's consciousness, so that one can discover and then test relationships among the data. If you reject the datum of your own self-awareness, then you can claim that anything I do to demonstrate the contrary is unreal, an illusion (which you must be conscious to experience, but since I must be wrong, logic must not apply). That is to say, rejecting the datum of your own consciousness is unfalsifiable, and therefore unscientific. Because science accepts only statements that are falsifiable (capable of being proved wrong), in principle, by some sort of observation (a means of getting data into consciousness) or experiment (a controlled means of getting data into consciousness). Science is thus a way to get to know by successive approximations (trial and error) those aspects of reality amenable to its methods.

In short, claiming that we are unconscious is unscientific, unphilosophic and leads to logical contradictions. And that is, as mathematicians say, "what was to be proven," Quod Erat Demonstrandum, QED.

Of course, it is possible that my friend mis-spoke. Perhaps what he really wanted to deny is the reality of the self. Here he might be on firmer ground, because Buddhism claims that an individual's sense of self is illusory. That is to say, that your own little sense of self is an illusion entertained by part of the Universal Self.

I think what the Buddhists are trying to say, however imprecisely, is that you are not your personality. Indeed, you build your personality on the foundation of your temperament in order to have an interface with the people and the world around you. You use your personality to relate to yourself, as well. The Buddhist koan, "Show me the face you had before your parents were born," is a demand to experience and relate to reality directly, without the intermediary of your personality.

But that doesn't mean that your personality is unreal. If you build a bicycle, the bicycle is no less real for your having built it. If you write a piece of software, the software is no less real for your having written it, or for it being the expression of your ideas. Similarly, your personality is your real creation, more intricate and grander than any art or literature ever created. It isn't an illusion. It just isn't all there is to you. And if your personality changes over time in response to your circumstances, so what? You might want to make changes to the bicycle you built as you grow, or as you age. So too, you may change your personality, albeit with some difficulty, and sometimes with the aid of a psychotherapist.

Having dealt with consciousness, we now turn to the thornier problem of free will. What my friend above should have been trying to establish was not the solipsistic ideas that we are unconscious or have no personalities, but rather the idea that although we are conscious, we only have the illusion of free will. We may be self-aware, but all our thoughts and actions are pre-determined reactions to preceding stimuli. We only think that we actually decide anything. This will be the topic of the next post in this thread.

Give Cain a Chance  

It appears that someone from the Rick Perry campaign has leaked that someone in the past may have accused Herman Cain of sexual harassment. If any other political office were at stake, I would be interested. But this is the Presidency of the United States of America. Neither Herman Cain nor Rick Perry have done anything that Bill Clinton didn't do. In fact, Bill Clinton was accused of doing worse. But Bill Clinton was a pretty good president. So, I give both Cain and Perry a Clinton pass on this one. I recommend that you do the same.

The nation stands on a precipice regarding its power to influence world events in its favor, while the media focusses on the banal and the trivial. The media are not serving us well. There are other, better reasons to reject or to consider either of these men for the office they seek.

And there are other, more important stories to follow, like crony capitalism on the part of both Democrats and Republicans, the gerrymandering that undermines the foundations of our Republic, and the proliferation of rules and laws that undermine the Rule of Law itself.

Occupy Wall Street: The Real Story  

The Occupy Wall Street people seem to have no clear idea of what they want and why they are occupying anything. It turns out, however, that they may have more of a point than they realize. Take a look at this Science News article entitled, "Financial World Dominated by a Few Deep Pockets." Researchers have determined that 40% of all the world's wealth in the financial markets is controlled by 147 corporations. You download a PDF of their original paper, "The Network of Global Corporate Control," at arxiv.org.

These 147 corporations (mostly investment banks and brokerage firms) are highly interconnected. This has a number of policy implications. First, when one goes down, it can take the others with it — this can destabilize the entire global economy. And regulators in any one nation are pretty powerless to do anything about it. Second, those who want to forecast market conditions might do better to scrap their statistical models and just monitor what these 147 are doing.

What they are doing is properly the subject of further study, but I'll take a guess, which brings us to a third policy implication. I think they are concentrating wealth. True, they redistribute some wealth to buy off the forces that would try to take control of them if they concentrated wealth too fast, or too intensively. And if they really mess up, they might redistribute a lot of wealth (or a lot of debt in the case of Lehman). They give us little guys some chance to get our small cut. But over my lifetime, the average net flow has been away from the middle class in places like the US and Europe. I assume that it's been toward the big players. But that's a subject for further study as I said.

The concentration of wealth and the flows of wealth enabled by globalization and high-speed networking are things worth watching, by national policy makers acting together around the world. It is also worth watching by investors. Maybe they should learn more about their investments and actually vote their shares.

Mother Doesn't Live Here Anymore  

In 1959, when I was a child, our family house looked like this:


Fifty years later, in 2009, when Mother died and we sold the place, it looked like this:


I guess my parents were inspired by the style of houses in Colonial Williamsburg. The two-story white houses with the green shutters, the old trees, and the hedges. Even their silverware was from Colonial Williamsburg, as was a pewter mug they had bought. Perhaps the look was out of place in our part of Appalachia, but we liked it, and the neighbors grew to like it, too, as they grew to like Mother.

Now it looks like this:


The giant old oak is gone from the front yard, as are the hedges, the eagle over the front door, and the green shutters.  Gone is the stone patio and fireplace that the owner previous to us built with one of his neighbors in back of the house. Gone, too are the stone walkways in the front yard, and the old-fashioned lamp post by the driveway. The rose Mother transplanted from her parents house when they died in the 1960s has been pulled out. No more Colonial Williamsburg. After more than half a century, the property looks more like it belongs to its Appalachian locale.

The neighbors, long-time family friends all, are taking some time to get used to it. Every time they look at it, it screams at them that Mother doesn't live here anymore.

To me, it looks as if we had never lived there. To me, it says that there comes a time for all of us when we can't go home again. And that, if we have the hubris to leave behind any monuments to our past, we had best not look back.

Now new children play in the yard, filling the place with with memories that will seem magical to them in years to come, because it will have been their childhood home.

A Message from Lance Armstrong  


Your chance of getting cancer increases roughly as the third power of your age. It doesn't matter who you are, where you live, what you eat or drink. Cancer is rough to live with, and even rougher to die from. Whatever else you can say about Lance, he's serious about his campaign to beat cancer. Maybe you think he's a cheat. But at a time when his accusers say that everyone was cheating, that means the playing field was still level - the competition was still equalized. Whatever he did, it was below the level of detection, which is all any detection system can guarantee. I think he's a little bit crazy for living and training the way you have to live and train to win the Tour de France, year after year. And I think he's a hero, who made the journey from dying to winning. But I think he's a hero especially because of his Livestrong Foundation work. Now... what do I have to wear that's yellow?

The Next Christian Martyr?  

The government of Iran is about to execute Youcef Nadarkharni for the crime of being a Christian Pastor in a Muslim country. If the mullahs go through with it, he will not be the first Christian martyr, not even in modern Iran, nor will he be the last. Unlike those jihadi-takfiris who murder themselves and as many others as they can find and pretend to be martyrs, we will witness Iranian clerics making a real martyr of a man for the simple reason that he is called to worship the same God as they, but in a different manner — the manner of a Christian.

Christian Solidarity Worldwide is monitoring the case. You can click here to help.

Update 10/1/2011: The Iranian government is changing their story. Now they claim they are going to execute him for the "security-related" crimes of rape and extortion, rather than the crimes of "turning his back on Islam," and "converting Muslims to Christianity," which were the only crimes mentioned in the court documents from his so-called trial. We note here that Mr. Nadarkhani claimed he was never a Muslim before he became a Christian. Look, the bloody-minded mullahs of Iran just want to kill this guy, never mind the precise charges. Kind of reminds you of the Crucifixion, doesn't it?

Update 10/3/2011: Now the Iranian government has added the charge of being a Zionist, which makes him a traitor to the government, one of the most serious charges that can be made against a person in Iran. They are getting really serious about killing this person, this husband, this father. You can tell by the way they are trying to make themselves feel good about it. Where are the protests about this?

If the Iranian government executes Youcef Nararkhani, then they will be cursed by the Blind Chihuahua even more so than they already are. Feel free to tell them so.

Happy New Year  

This coming Thursday is Rosh HaShanah, the beginning of the New Year 5772 of the Hebrew Calendar. Yes, Jews, although never particularly numerous in comparison to many other peoples, have been around as long as civilization. Religious Jews believe themselves chosen by God to live according to God's commandments. Such special election does not imply that Jews think themselves better than anyone else, or entitled to special considerations from anyone else. It implies that Jews believe themselves to exist to keep God's commandments, and that God's promise to them is that as long as they keep God's commandments, they will continue to exist as a distinct people.

Keeping God's commandments can get complicated, because many of them were written down thousands of years ago in circumstances that no longer exist in this world. Therefore, keeping the commandments has become a matter of interpretation and debate, which has lasted for nearly two thousand years. The Talmud records several centuries of detailed discussion and commentary regarding how one can best live in fulfillment of God's commandments in a changing world.

But one of the commandments is to live in accord with God's commandments joyfully. So, Happy New Year, Shana Tova, everyone!
