Why materialism ?

Well, a few days back our esteemed member UndercoverElephant implied that I cannot accept this dualistic ideas because I'm a materialist. Well, that's tautological, but what he actually said is that I cannot accept the idea that there is something as "free will" because I'm a materialist.

So, let's see why I'm a materialist, and how the way I see things affects my view of free will, shall we ?

Now, in order for one to reach any conclusion whatsoever, one needs to make a few assumptions. I think anyone, espousing any metaphysics, will agree with my basic assumption: Something exists. It would be hard to claim that nothing exists, for even if what we observe is an illusion there is the illusion. So now we know there is some sort of universe we think we observe, but we don't know at this point what it is or how it works.

I also think we'd all agree to say that something cannot exist and not exist at the same time, or rather, that something and its opposite cannot both be true simultaneously. The glass is either full or it isn't, the engine is either running or it isn't, and an event is either caused or not. But it can't be both or neither. That's very important because we have to be able to draw definitive conclusions based on observation. Once a proposition is known to be true, it can't be false, and vice-versa.

So we know something exists, and we know we can reach conclusions about various aspects of it.

Now, we can only draw conclusions about we can observe. However, there are several possible conclusions to our observations. Since I assume we prefer knowing the truth than the lie, drawing the correct conclusion is crucial. Otherwise there's not much we can use this conclusion for except mental exercises.

Solipsists claim that we can only ever be sure about our own thoughts. Funny they say this, because I don't think we're that sure about them. Idealism is broader but basically makes the same claim: that all is mind. It's not a very useful claim, I think, because whether or not it is true, the universe behaves in the same way and our observations still work. If all was mind (mine or all of them) I'd expect it to be slightly less consistent: without exception, every other manifestation of my mind (thoughts, delusions, hallucinations, dreams, etc.) is horrendously unreliable and inconsistent, to the extent that we often notice it even in their context. There's never such a problem with observable reality. It remains the same no matter what I wish, and no matter in what state we are. And even if your perception itself can be altered, in its "neutral" state things go right back to what they were.1

So, if idealists are claiming that mind actually generates reality, they are making a claim that is inconsistent with observation. If not, they are making a claim that is indistinguishable from materialism, under which reality is independent from the observer -- or rather, the observer belongs to reality, and not the other way around. Dualists have an even harder time, because if "souls", or whatever other similar entity they posit, is immaterial, then it cannot interact with the material, and so both sides of the dualism will never affect one another. If they CAN interact, then we can, even if only in principle, detect their influence, because the event itself isn't caused by observable causes. But that never happens.

What we're left with is materialism. And so far, I call it very successful, indeed.

The amusing thing is, however, that under ANY of those metaphysics, free will doesn't make any sense. So me being a materialist has nothing to do with it, because the logic that makes free will inconsistent doesn't depend on it. Why is it inconsistent ? As I said, something is either true or not. Events are therefore either caused or not. If they're caused, then they are wholly constrained by the causes. If they are uncaused, then they have no discernable prior state and no predictable outcome, and are therefore either random or indistinguishable from being random. A combination of both caused and uncaused doesn't solve the problem.

So that's pretty much how I see things. Objectivist, materialist. And unrelated to that, a non-believer in free will.

Thoughts ?

1: I know there are "arguments" around this. We're never 100% sure about anything, anyway, right ? But since I'm a very "for all intents and purposes" kinda guy, I usually ignore the extremely improbable and frivolous claims. It's easy to dodge problems when you make unwarranted assumptions, but I'm justifiably wary of claims whose truth value we could never ever know, even in principle. Falsifiability and Occam's Razor, and all that.

I think you may be using a definition of materialism that is something like "however things are, that's materialism." In which case, of course, who can argue? Not me, that's for sure.

But philosophers have to nuance the definitions of materialism, idealism, neutral monism, etc., in order to distinguish them and have anything to talk about. Someone nasty once said that when all the science was pulled out of philosophy and made into science, the philosophers rallied 'round to make sure that what was left did not include anything that anyone else would ever want to pull out. It may be that philosophers will one day discover something that clearly selects among all the metaphysical models, but personally I think they have put themselves in a position where that is not possible. All the models, down deep, are equivalent when the light of reality is shone upon them.

Yep, sometimes I think there are too much "-isms"...

Well, its my personal opinion that free will is usually poorly described or defined even by those who believe its real - maybe because its not real.

"-isms" apart, I think free will is not real, we only experience the illusion of having it (and I'm OK with that). The number of choices available is always limited; within the group of available choices, there is always a preferred subgroup, defined and ranked by many variables (cultural background, profit/gain perspective, risk evaluation, emotional state, external pressures, etc.). This certainy makes a deterministic prediction of the outcome difficult in many cases. But I believe a statistical approach is theoretically possible - one could derive the probability for a certain decision being taken. This assumes that we will be able someday to build a model for the decision-making process and feed it with the required data. Call it a leap of faith, if you will. The fact that we can't do it or fully understand it nowadays doesn't mean in the future we will not. Many of yesterday's gaps are filled today...

I've often said free will is non-existant, in an absolute form, under theism or under materialism (by theism, I'm referring specifically to those who believe in a timeless, omnipresent, omniscient creator god). I myself am a dualist, but I think dualism is an irrational and illogical stance to maintain.

Free will is the stumbling block many people have. Some think that their God gave them free will as some kind of magical, special gift (sounds more like a vile curse, to me). Some can't accept the idea that their decisions are already set in stone, so to speak, over the course of their lives. Maybe that's one of the bad side-effects of our new rational way of thinking. We've set aside antiquated notions like fate and destiny, not realizing that, in a way, those notions are more relevant now than ever. After all, fate and destiny are merely ways of realizing that free will IS just an illusion.

As Roland would say, 'Ka.'

No, no, it's not directed at you. I just couldn't help thinking that if he were still around, he'd certainly have a few things to say. (Few people see things the way he does)

So you are saying that you simply don't believe in free will and that it has nothing to do with whether you are a materialist? Is that correct? Was UE trying to say that materialism precludes free will, or was he attempting to ascribe that position to you? I'm not sure if I'm understanding the first paragraph in your OP.

Are you saying that there is no free will because an event presumed to have been brought about by free will is therefore uncaused and as such is a contradiction? If that's the case, what about the possibility that, individually, we have free will, but collectively the so-called choices of humans is more like a quantum foam, so that what seems random on a micro scale, tends to even out when viewed on a macro scale. Or maybe it's other way around--individuals make random choices which when humanity is taken as a whole, emerge as having an ordered structure.

It's not that an uncaused event is a contradiction, it's random.

It seems that you are equating free will with randomness. I don't think that's of any comfort to the libertarian free will-ist.

No, it's because an event is either caused (deterministic) or not (random), and in both cases there is no "freedom" involved in the libertarian sense.

Quite the opposite. Free will is the freedom to make choices. Making choices means weighing options in a manner flavored with your personality and your current context vis-a-vis external reality.

Free will can thus only be a deterministic process. Of course you can throw in a few true, quantum-random particles from time to time to scramble it a bit, but that doesn't really affect the core nature of free will.

I have yet to see a definition of how some mystical spirit-essence would arrive at a decision that does not boil down to this. It would have to have some kind of effect on the process that is neither deterministic nor truly random. Not exactly sure what this is, or how it operates, or how it could even exist.

Can anyone provide me a descriptive property of said "spirit" entity plugin, for lack of a better term? It makes decisions which are neither deterministic nor random. By this I mean...???



Leave aside for now the idiocy of trying to sway such a thing by threats of punishment or promises of reward, which are clearly deterministic* inputs.






* And sometimes capriciously random, too, according to how Yahweh operates in the Bible. :rolleyes:

So the claim that an event is the product of free will is basically a claim that the event was neither caused nor random, and therefore impossible, then. Is that it in a nutshell?

Paul, thanks for your clarifications. I'm not sure I meant to equate free will with randomness, but I was thinking that perhaps it's possible that one gives the appearance of the other. But in which direction?

I have lots of problems with materialism for a number of reasons. One reason that I have doubts about materialism is that there is evidence that material itself as we think of it at one point did not exist. The fact that the Big Bang was itself what created matter and space and time seems to imply (under normal intuitive logic) that there was a vast pool of energy that must have created it. If you look at the very beginning of finite time based on the mathematical calculations, there appears to have been infinite temperature and density from which all finite mass and space expanded itself from. To me, this process implies the paradox that our finite material reality was created from a greater infinite energy reality. However, as so many atheists are quick to point out, the chain of causation (time) did not exist before the Big Bang so it is supposedly improper or meaningless to make any such assumptions because the idea of "before" the Big Bang makes no sense in an absolute way. But personally, I believe that this does not mean we have to throw out all ideas of what exists "before" the Big Bang, but rather if something like cause and effect did exist "before" the Big Bang, all it means is that this cause and effect was not subject to our normal rules of physics. Therefore, it can be argued that there is some sort of energy and momentum that transcends our material laws in which our material existence is subordinate to this greater energy.

I'm not saying this greater energy HAS to be interpreted as spiritual (maybe the Big Bang was caused by two branes colliding as some string theorists suggest). But my point is, accepting materialism is often just as faith-based as rejecting it. As far as the existence of two or more states being possible simultaneously, this is still a controversial subject. But I do believe it might have some bearing on the nature of free will since some scientists have speculated that consciousness may be the result of a quantum mind. Quantum physicists still can't entirely agree whether or not superposition truly exists or whether the idea is the result of a flawed understanding. Nobody really knows how quantum physics affects the big picture of the reality we perceive, but it does underly the nature of all physical reality, and so the fact that it is so unintuitive and at times paradoxical should give us pause before we start to assume that the normal material reality necessarily represents the full and absolute truth.

For a bit of wild speculation based on nothing more than my personal experience: If free will exists, I think it might manifest itself as the ability to choose between going with the flow of materialistic instinct to survive for as long as possible (in spite of intellectually knowing that you will eventually fail) or rejecting it by being able to achieve a state of blissful detachment such as monks of some major religions claim to experience.

Seem to imply under normal intuitive logic. You don't seem very sure.

"Material" doesn't mean "atoms" and "quarks". Material as in "materialism" includes energy and all that is observable.

Otherwise the rest of your post sounds like "I don't understand the physics behind all this, so I'd rather believe differently".

The trick is to come up with a method for making free decisions that, although it might look random, is in fact neither random nor deterministic. I don't think there is any logical room for such a beast.

My knowledge of quantum physics is admittedly not that great, but I do make attempts to understand it. Obviously I'm not sure about what quantum physics implies in totality, but that's not a big deal because the scientific community is also not sure. This is why there are so many "quantum interpretations", some of which conclude that that there are parallel universes and others which posit that consciousness itself can cause the collapse of the wave function.

If you know more than me on the subject of physics, why would you make a statement such as this:

"I also think we'd all agree to say that something cannot exist and not exist at the same time, or rather, that something and its opposite cannot both be true simultaneously. The glass is either full or it isn't, the engine is either running or it isn't, and an event is either caused or not. But it can't be both or neither. That's very important because we have to be able to draw definitive conclusions based on observation. Once a proposition is known to be true, it can't be false, and vice-versa."

The possibility of the existence of simultaneous opposing states has been considered an open question of quantum physics for the last 80 years. Although some scientists but not all consider it partially resolved, there is still much unresolved "spookiness" to quantum physics, even in the words of quantum physicists themselves. Since you take for granted that opposing states can not concurrently exist, please feel free to tell us your solution to the famous Schrodinger's Cat thought paradox..

Absolutely. And I agree that is an open question as to whether or not it was caused or just sort of happened on its own.

I guess the point I'm trying to make is that because there are still many open questions such as this regarding the basic fundamental truths of reality, I think being materialist is based more on opinion/guess or possibly faith than anything else.

It took a long time for scientists to get used to the idea of the Big Bang precisely in part because the idea of a finite point of creation did seem to sound more spiritual than scientific at the time. Many scientists would have preferred the idea of a static, unchanging universe because then a transcendental Will could be more easily ruled out. This sense of unease regarding the Big Bang was heightened by the fact that the Theory was introduced by a Catholic priest.

That would be an argument from ignorance. So far, every observation ever made and every theory and conclusion ever reached has been consistent with materialism. Now, it may be wrong, as a bare possibility, but just because we don't know one or two things is no reason to abandon the most successful metaphysics and start going solipsist, for instance.

Back to the drawing board. `We must teach it the difference between relevant implications and irrelevant implications,' said the designers, `and teach it to ignore the irrelevant ones.' So they developed a method of tagging implications as either relevant or irrelevant to the project at hand, and installed the method in their next model, the robot-relevant-deducer, or R2D1 for short. When they subjected R2D1 to the test that had so unequivocally selected its ancestors for extinction, they were surprised to see it sitting, Hamlet-like, outside the room containing the ticking bomb, the native hue of its resolution sicklied o'er with the pale cast of thought, as Shakespeare (and more recently Fodor) has aptly put it. `Do something!' they yelled at it. 'I am,' it retorted. `I'm busily ignoring some thousands of implications I have determined to be irrelevant. Just as soon as I find an irrelevant implication, I put it on the list of those I must ignore, and...' the bomb went off.

But the cat doesn't exist and not exist at the same time: we just don't know.

By overlooking possibilities, you are revealing your own particular biases again. Using "normal" logic, I would agree that it seems that an object that is both living and dead seems impossible. But you apparently don't know enough about quantum physics to realize that, although a controversial topic, it may be possible for simultaneous contradictory states to exist even on the macroscopic level.

There is a news article from a few month back entitled "How to Build 'Living Dead' Quantum Objects: Schrodinger's Cat may Soon be Possible" that you might want to google since I can't yet post links. But I will paste the first few lines from it:

"Following important advancements in the field of quantum physics and energy, scientists are currently working on a way to create Schrodinger's cat, a macroscopic object that is both dead and alive at the same time. It takes advantage of oddities recorded in quantum mechanics for electrons and molecules, which researchers say could translate to large objects as well.

However, the potential maximum sizes these hypothetical objects could reach is not yet clearly determined, but experts from the University of Arizona in Tucson took the first steps towards proving that a system of two objects can act as a whole, or as two different components working independently from each other."

Now, it may be wrong, as a bare possibility, but just because we don't know one or two things is no reason to abandon the most successful metaphysics and start going solipsist, for instance.

I wouldn't say there are just one or two things we don't know. And some of the things we don't know are so pervasive and fundamental that in certain respects, it is actually quite embarrassing for many physicists to the point where they often now ignore the unobservable phenomena that connects their findings by labeling it unprovable "philosophy." In quantum physics, there are more new questions being raised than solid answers being found on a continuous basis. And to this day, no scientist has adequately solved the problem of what exactly allows for the nonlocal effects of quantum entanglement. This is what Einstein once called "spooky action at a distance." Two entangled particles could be separated by a space of billions of miles, and yet when an action is performed on one particle, the other particle would also respond. To me and most scientists, this signifies a HUGE gap in our understanding. It could allude to a vast, perhaps all-encompassing and unobservable backstage field of connectivity.

To put it simply, our sense of observable materialism may be like a small frame inside a much greater unobservable field that does not play by our "normal" rules. To use a crude analogy, if you had a character in a video game who could magically become sentient, how could he ever prove that there is a world outside of his limited frame of reference even though there might be clues but no solid evidence of a greater force? This is much the case with string theory which is also itself not based on observable evidence but rather on conveniently tying loose ends together.

Again I agree. And when the scientists are unable to connect the two fundamental systems of physics even after 80 years, they eventually just give up by calling the problem "philosophical in nature" allowing them to ignore it, or they make up fanciful and fundamentally untestable "theories" such as String Theory so they can sleep more soundly at night.

Quite the opposite. Free will is the freedom to make choices. Making choices means weighing options in a manner flavored with your personality and your current context vis-a-vis external reality.

Free will can thus only be a deterministic process. Of course you can throw in a few true, quantum-random particles from time to time to scramble it a bit, but that doesn't really affect the core nature of free will.
This is how I see it too. When alternative courses of action are possible (in principle), 'free will' is the label we give to the conscious awareness of the process of selecting the course that most closely matches our 'preferences' (projected preferred state) at some moment - those preferences being a weighed sum of various internal biases compared against the projected results of the alternative actions (or the memory of previous similar projections). It's all deterministic, but, with self-referential processing involved, potentially unpredictable - like the weather, periods of relative predictability may be interspersed with chaotic periods of unpredictability. ISTM that all that matters for 'free will' is that we are aware of weighing the options and acting on the result, and are not aware of undue constraints or coercions. On one level, it is illusory because the process is deterministic, on another level it's quite valid as an experiental phenomenon - the action that is the choice is the result of complex processing that is unique to the individual and the individual is aware of that.

One problem with this is how does true randomness creep into a deterministic system of choices made by living beings? Studies in entomology have shown that insects, even when the environment is very limited and variables strictly accounted for, will still move in individualistic, unpredictable patterns. You could argue that they are wired for randomness through deterministic means, but this is a bit of a paradox I think if the process of how the randomness occurs cannot be accounted for.... Where is the virtual dice and thrower that makes one cockroach zig while another zags?

As for free will in more complicated beings like humans, I think you have to take things like cognitive dissonance into account. You make it sound as though a person's mind will constantly weigh out biases and information and come to a singular choice of absolute resolve, but I think you are oversimplifying it. For example, the conscious mind often has a very different view of a given situation than the unconscious mind. Sometimes I make decisions I absolutely hate, knowing full well that I should not choose a given path even as I am making the decision, but yet I allow myself to cave to my unconscious fears. These unconscious fears are not just simply biases or prejudices; they are things my conscious mind absolutely 100 percent knows are no big deal and yet I sometimes allow them to have power over me. How can all decisions be described as a deterministic weighing-out process if there exists more than one part of the mind capable of making decisions? If you say that one side of the mind will always triumph over the other, what causes the success in light of the fact that on another day with a similar mindset, the other path may have been equally likely to occur? Sure, it could be a complex illusion to believe that both paths are equally likely to occur especially given so many variables in human life, but I don't see why if it is an illusion, the illusion should exist in the first place. If free will wasn't real, why would the mind need to create unpleasantness as a side effect for a decision we know we probably shouldn't have made? In this case, we should just be philosophical zombies who would experience emotions as mere attachment with no sense of "qualia." From an evolutionary standpoint, we don't need to have such feelings of dissonance to function and be successful so they should simply not exist because they actually get in the way of our pursuits. As another example, if I had a nightmare last night or even daydream that I found extremely unpleasant, what allowed my unconscious mind to allow for something that my conscious mind would have vetoed?

One problem with this is how does true randomness creep into a deterministic system of choices made by living beings? Studies in entomology have shown that insects, even when the environment is very limited and variables strictly accounted for, will still move in individualistic, unpredictable patterns. You could argue that they are wired for randomness through deterministic means, but this is a bit of a paradox I think if the process of how the randomness occurs cannot be accounted for.... Where is the virtual dice and thrower that makes one cockroach zig while another zags?

I hope you are not being serious here. Getting different results from, if even yet so slightly different starting conditions is not very surprising. Test it out with a pRNG if you like.

And a study on bugs, even if exceptionally well done, can hardly control all factors involved. Cockroach A is not Cockroach B for a start. Some unpredictability in the observed behaviour bugs is a far cry from objective (or true) randomness.

There isn't much free will.
Our decisions are coerced by our family, boyfriends, girlfriends, peers, cow-orkers, camping buddies, neighbours, local courts, the IRS, and waste management engineers.

Free will in the west means a jail sentence in many cases, and ostrification in others.

Fair enough. I see now that my example was not very good.

The point I was trying to make was that the behavior found in simple organisms may not be truly deterministic, but using bugs made for a bad example because their brains are probably actually fairly complex and could possibly, as you mention, have some kind of framework to support pseudo-random behavior.

But if it is fair to say that Cockroach A is not the same as Cockroach B due to complexity of the brain and body which may allow for noticeable differences, this becomes a harder position to defend if we take the discussion to the level of micro-organisms. It seems to me that these creatures should be much less random as their potential for intelligence decreases IF there is a case to be made for determinism as the sole root of their behavior.

Therefore, let me give another example that may at least cast some doubt as to whether even single-cell organisms are governed by purely deterministic behavior. This passage is taken from an article regarding the difficulties of creating artificial intelligence that would mimic even the lowest level of creatures.

"Even the simplest living organisms do not display two-valued logical behaviour. Non-determinism is built in from the very bottom level. Consider a piece of the cell membrane of a paramecium in water, which has touched a possible food particle. In order for the food particle to be ingested, a reaction needs to take place between the food particle and some sort of receptor on the surface of the cell. The molecules of both the food particle and the receptor are large (probably proteins, or fatty acids). The reaction occurs when the reactive parts of the molecules of the reactants become close enough to each other [1]. Both reactants are in motion because of their temperature, and because of Brownian motion induced by the water molecules. The likelihood of a reaction occurring is directly related to the likelihood of the reactive surfaces meeting each other before the same random movement causes the food particle to move away from the cell. This whole process is essentially nondeterministic.
Virtually all the processes that occur at the cell membrane are of a related form:for example, ion channels which alter shape due to variations in the charge patterns surrounding them are actually continuously in motion, and their shape is essentially best described as a stochastic system [2]. Thinking of ion channel behaviour as being like transistor behaviour (as Mead suggests in his 1989 book [3]) can therefore be slightly misleading. We conclude that there is diversity in response in biological systems even at the lowest level."

Here is an excerpt from an interesting Wikipedia article on the process of chemotaxis in microorganisms which also calls strict determinism of even the most simple organisms into question:

"The overall movement of a bacterium is the result of alternating tumble and swim phases. If one watches a bacterium swimming in a uniform environment, its movement will look like a random walk with relatively straight swims interrupted by random tumbles that reorient the bacterium. Bacteria such as E. coli are unable to choose the direction in which they swim, and are unable to swim in a straight line for more than a few seconds due to rotational diffusion. In other words, bacteria "forget" the direction in which they are going. Given these limitations, it is remarkable that bacteria can direct their motion to find favorable locations with high concentrations of attractants (usually food) and avoid repellents (usually poisons).
In the presence of a chemical gradient bacteria will chemotax, or direct their overall motion based on the gradient. If the bacterium senses that it is moving in the correct direction (toward attractant/away from repellent), it will keep swimming in a straight line for a longer time before tumbling. If it is moving in the wrong direction, it will tumble sooner and try a new direction at random.
...
It seems remarkable that this purposeful random walk is a result of simply choosing between two methods of random movement; namely tumbling and straight swimming. In fact, chemotactic responses such as forgetting direction and choosing movements resemble the decision-making abilities of higher life-forms with brains that process sensory data."

http://en.wikipedia.org/wiki/Chemotaxis

There is also some evidence that some single-celled organisms such as the paramecium are capable of some kind of learning despite having no neurons or a brain.

I think that when the article says that the "whole process is essentially nondeterministic" the "essentially" is key. ;)

But all this doesn't even matter. Even if you showed something in the strictest sense undetermined that would not help along free will, that is, libertarian free will. You'd just show something that happens the way it does for no reason at all.

One problem with this is how does true randomness creep into a deterministic system of choices made by living beings? Studies in entomology have shown that insects, even when the environment is very limited and variables strictly accounted for, will still move in individualistic, unpredictable patterns.It would be quite possible for parts of the neural network to be sensitive to random influences, such as noise in the system, or even generate random (or pseudo-random?) noise, and I would be surprised if simple organisms didn't make use of randomness in their tropisms. It's also possible that this kind of thing is used in higher animals (some sensory processing has been shown to use noise to raise the threshold of sensitivity). But the main point is that randomness is not necessary if the output of the processing is sensitively dependent on the initial (and ongoing) states of the processor and/or if self-referential processing is involved. Remember that this is not a passive system simply awaiting the inputs on which to make a decision, but a complex active system, with numerous continually changing states.

As for free will in more complicated beings like humans, I think you have to take things like cognitive dissonance into account. You make it sound as though a person's mind will constantly weigh out biases and information and come to a singular choice of absolute resolve, but I think you are oversimplifying it.You inevitably have to simplify these things when describing them in a paragraph or two.

For example, the conscious mind often has a very different view of a given situation than the unconscious mind. Sometimes I make decisions I absolutely hate, knowing full well that I should not choose a given path even as I am making the decision, but yet I allow myself to cave to my unconscious fears. These unconscious fears are not just simply biases or prejudices; they are things my conscious mind absolutely 100 percent knows are no big deal and yet I sometimes allow them to have power over me. How can all decisions be described as a deterministic weighing-out process if there exists more than one part of the mind capable of making decisions?You are quite right that there seem to be many sub-processes or sub-modules involved, each with competing priorities, and they all provide input into the evaluation. At some point an action must be initiated and it seems to me that it will depend on the status of the system at that time - crudely, which of these competing priorities has had the largest influence during the evaluation. It seems likely that preparation for one or more potential actions builds up as the evaluation is in progress, so that the appropriate behaviours can be initiated for the action that is best prepared for - just my speculation.

If you say that one side of the mind will always triumph over the other, what causes the success in light of the fact that on another day with a similar mindset, the other path may have been equally likely to occur? Sure, it could be a complex illusion to believe that both paths are equally likely to occur especially given so many variables in human life, but I don't see why if it is an illusion, the illusion should exist in the first place.I don't really see the problem. It doesn't really matter which of the courses of action is selected or which of the internal modules 'wins out', the result is what we call our 'choice', and if we feel it was uncoerced, we call the process that gave that result 'exercising our free will'.

The system has evolved to resolve the competing priorities in a timely manner so that the most appropriate behaviours can be initiated. It's not necessarily a rational process, and the contribution from introspective conscious awareness complicates matters and can make it dangerously unreliable (although the benefits must outweigh the disadvantages, or we wouldn't be here). The system is arranged so that, in general, sufficient processing and evaluation is done to select appropriate behaviours, and these behaviours are initiated while they are still appropriate - we wouldn't survive long if we didn't think enough about what to do next, or if we thought so long that we missed our opportunities.

It seems to me that the nuts & bolts of this processing is below our conscious awareness - we will be aware of some of the competing priorities, some idea of the leading preference, and we can guide the focus of attention to particular areas, but there is evidence that the evaluation is completed and behaviours are initiated subconsciously, and the 'self' becomes aware of this after the fact and a plausible narrative is generated to explain it. It's still 'us' exercising 'free will', but we're not necessarily consciously aware of all the details of the decision making process, any more than we're aware of how we generate our utterances in conversation. Who hasn't blurted out some tactless comment or made some particularly clever quip and wondered where it came from?

If free will wasn't real, why would the mind need to create unpleasantness as a side effect for a decision we know we probably shouldn't have made? In this case, we should just be philosophical zombies who would experience emotions as mere attachment with no sense of "qualia." From an evolutionary standpoint, we don't need to have such feelings of dissonance to function and be successful so they should simply not exist because they actually get in the way of our pursuits.I don't particularly see what unpleasantness has to do with free will. From an evolutionary viewpoint we do need to distinguish between what is desirable and what is undesirable, and the senses and the sensations they produce are the means by which this can be done. Unpleasantness crudely steers us away from things that may be detrimental - it's a fundamental principle in the evolution of living things. Without pain we wouldn't be aware of damage and learn to avoid the things that cause it. Without hunger we wouldn't eat, without fear we'd get into too much trouble. The mechanisms that manage these sensations are inherited from our earliest beginnings and haven't changed much in millions of years. Our fancy brains are built on top of these foundations.

As another example, if I had a nightmare last night or even daydream that I found extremely unpleasant, what allowed my unconscious mind to allow for something that my conscious mind would have vetoed?Why do we dream? Why do we have nightmares? I don't think anyone really knows for sure, but in sleep the confabulator or narrative generator is allowed to free-associate with minimal constraints of logic and commonsense, perhaps to make connections between recent experiences and memories, or to produce new links between apparently unrelated areas (e.g. creativity?). Given the importance of unpleasantness to survival, it's not surprising it can appear in dreams, if dreams have some constructive purpose and survival value. Personally, I only seem to get nightmares when I'm too hot in bed - as if the subconscious uses the physiological effects to wake me up so I can throw off some bedclothes...

Last night I ended up reading several articles on the subject, and it seems as though there is no clear consensus among microbiologists as to whether or not the behavior of these creatures represents objective randomness or whether it's just easier to think of it as a stochastic system.

I'm not trying to prove free will because I don't feel that I have the capability. The reason I got caught up in the random/non-random debate was because somebody here equated non-randomness with determinism or at least implied an overlap between them. Personally, I am just trying to prove that behavioral randomness might exist because then, at least, it might make room for the possibility of free will. A person arguing against me could always just say "Oh, well, the seeming randomness is due to a hidden variable we haven't discovered yet." On the other hand, a lack of free should be easier to prove, at least on the micro-organism level, because one would simply need to predict the timing of its movements in reaction to stimuli. At some point, it would be fair to consider a micro-organism a biological robot if you could truly gain a full understanding of its timing and range of behavior.

I agree with your paragraph, and you bring up good possibilities; I definitely regret bringing up the insect example. However, in the case of the unicelluar organism, it does not have a brain or a typical nervous system beyond simple microtubules. As far as my limited knowledge of it, it seems as though it can't really process anything in the normal sense beyond basic chemical reactions, which is why the Wikipedia article I linked to probably keeps using words like "remarkable" to describe how its processes have the feature of masquerading as more complex behavior. If the appearance of randomness is based on noise or other factors in these one-celled creatures, I would assume that those factors should eventually be accounted for and fully explained by scientists.

Science is very advanced in some fields, but if we cannot even explain EVERY aspect including the timing of movements in a single-celled organism, how can we ever hope to understand something as complex as a human brain? I'm not saying that this would be an impossible feat, but I am suggesting that the study of objective human behavior is still in such a state of infancy that all debate supporting free will or lack of it is not just somewhat speculative, but rather incredibly speculative.


You are quite right that there seem to be many sub-processes or sub-modules involved, each with competing priorities, and they all provide input into the evaluation. At some point an action must be initiated and it seems to me that it will depend on the status of the system at that time - crudely, which of these competing priorities has had the largest influence during the evaluation. It seems likely that preparation for one or more potential actions builds up as the evaluation is in progress, so that the appropriate behaviours can be initiated for the action that is best prepared for - just my speculation.

All I can really do is speculate as well. To use an example of how I see it, imagine a contestant who is faced with a difficult question on the game show "Who wants to be a Millionaire." There are four choices for the answer: A, B, C, and D. The contestant reveals his thinking process to the audience by saying, "On an intellectual level, I feel torn between A and B. But my gut feeling tells me to go with C and I don't know why." He pauses for a moment. "Okay, now I feel like A seems like a better choice than B but my gut still says C." Then the host will say something like, "So are you going to go with your gut or you going to go with what your logic tells you?"

The point I'm driving it is that it seems as though competing priorities only apply to the obviously rational mind. I don't see any evidence either for or against the idea that there is a deterministic process that causes the subconscious to compete with the conscious. The gut subconscious feeling will not change, or at least is much harder to change by the very nature of what it is. Although this is highly speculative because it is based on my "feelings", the somewhat internally logical or condition-based mind seems to have multiple opinions which are being weighed out as you mention. The subconscious mind, assuming it is not reacting out of fear, offers alternative suggestions which are usually not coercive. (at least I don't ever feel coerced when I go with my intuition.) It just seems like another channel of possibility which is simultaneusly available to me. And since it feels like it is in a totally different realm that the competing priorities, it seems like a genuine choice, almost like a completely or partially illogical sublimation of the conscious mind to the totality of the whims of the universe. Maybe we have the ability to make random or pseudo-random decisions based on internal noise that we experience, but even if it's just noise, there could be a choice of whether to adhere to the randomness of noise or listen to your internal rational decision process.


I don't particularly see what unpleasantness has to do with free will. From an evolutionary viewpoint we do need to distinguish between what is desirable and what is undesirable, and the senses and the sensations they produce are the means by which this can be done. Unpleasantness crudely steers us away from things that may be detrimental - it's a fundamental principle in the evolution of living things.

The mechanisms that manage these sensations are inherited from our earliest beginnings and haven't changed much in millions of years. Our fancy brains are built on top of these foundations.

I'm not talking about unpleasantness in general; I'm referring to the subjectively intense feeling of lingering unpleasantness that is to the detriment of the organism. For example, the kinds of feelings that lead to severe depression and even suicide are not beneficial and yet these feelings are actually not particularly uncommon in human society. The fact that we can commit suicide does not prove free will, but I think it raises interesting questions as to why evolution has not made humans more hard-wired against depression and suicide.

Again I agree. And when the scientists are unable to connect the two fundamental systems of physics even after 80 years, they eventually just give up by calling the problem "philosophical in nature" allowing them to ignore it, or they make up fanciful and fundamentally untestable "theories" such as String Theory so they can sleep more soundly at night.

String theory is a theory of everything, which encompasses quantum gravity and more. Loop quantum gravity is not a theory of everything.

It may not be fair to write them off, but I whole-heartedly exhibit my disrespect to string theory and any other "theory" that dishonestly represents itself as anything more than a hypothesis, even if it is a very good hypothesis. As I recall from grade school on up through college, and here defined by Princeton's WordNet, "a scientific hypothesis that survives experimental testing becomes a scientific theory." Since when did scientists have the right to skip steps in their basic methodology?

The reason this annoys me so much is that, through their arrogance, these scientists are actually discrediting the whole scientific process to laypersons everywhere. It just reinforces the misguided beliefs of the average Joe Sixpack who keeps repeating "it's just a theory!" every time he sees a reference to even fundamentally proven theories such as evolution. This is why the rest of us who actually care about the public's understanding of science, no matter how dim it might actually be now, have actually resorted to having to constantly convince people that evolution is a fact. In my opinion, we wouldn't have to do spend so much time doing this if scientists agreed to replace terms like theory with "framework" or some similar word instead of trying to make their ideas sound more important even in the initial stages before they have been properly tested.

If and when string theory is at least partially discredited and eventually replaced by a better theory, and this indeed seems likely to me based on my readings, this will just fuel the fire of Joe's already flaming ignorance. (Sorry to pick on Joe so much, but I also reserve the right to diss him and his hypothetical gravy-stained shirt)

As for loop quantum gravity and some of the other attempts to reconcile the two leading systems of physics, I have read a bit but I don't know that much about them. If you think any of these "theories", have enough weight of evidence behind them to legitimately deserve the term, I'd love to hear about which and why.

Here's an example of how others agree that the term theory has been watered down, and yet they interestingly enough place none of the blame on scientists themselves. I agree that creationists contribute to the problem but it's time for scientists to also look in the mirror.

"Other commentators, focusing on the changes in species over generations and in some cases common ancestry have stressed that evolution is a fact to emphasize the weight of supporting evidence while denying it is helpful to use the term "theory":
R. C. Lewontin wrote, 'It is time for students of the evolutionary process, especially those who have been misquoted and used by the creationists, to state clearly that evolution is a fact, not theory.'"

How many people have you met who repeat "It's just a theory" because they are honestly confused about whether evolution is a theory or not, due to the influence of arrogant scientists? I would say that most people who repeat that canard do so because they don't want evolution to be a theory at all.

That said, sure, scientists could perhaps be more careful.

By overlooking possibilities, you are revealing your own particular biases again. Using "normal" logic, I would agree that it seems that an object that is both living and dead seems impossible. But you apparently don't know enough about quantum physics to realize that, although a controversial topic, it may be possible for simultaneous contradictory states to exist even on the macroscopic level.

So P and Not P can be true simultaneously ? Congratulations, you have just made the acquisition of knowledge impossible.

I wouldn't say there are just one or two things we don't know.

:rolleyes:

And some of the things we don't know are so pervasive and fundamental that in certain respects, it is actually quite embarrassing for many physicists

Puzzling, perhaps. Embarassing ? Such as ?

To use a crude analogy, if you had a character in a video game who could magically become sentient, how could he ever prove that there is a world outside of his limited frame of reference even though there might be clues but no solid evidence of a greater force?

Ah, yes. The Matrix analogy. How convincing.
