Panpsychism Involves Simplistic Shrinkage

The book Galileo's Error: Foundations for a New Science of Consciousness by philosopher Philip Goff is a book with quite a few misfires. The biggest one is an extremely common one among today's philosophers. The error is to use the way-too-small term “problem of consciousness” in discussing current shortfalls in explaining the human mind.

What we actually have is an extremely large “problem of explaining human mental capabilities and human mental experiences” that is vastly larger than merely explaining consciousness. The problem includes all the following difficulties and many others:

  1. the problem of explaining how humans are able to have abstract ideas;
  2. the problem of explaining how humans are able to store learned information, despite the lack of any detailed theory as to how learned knowledge could ever be translated into neural states or synapse states;
  3. the problem of explaining how humans are able to reliably remember things for more than 50 years, despite extremely rapid protein turnover in synapses, which should prevent brain-based storage of memories for any period of time longer than a few weeks;
  4. the problem of how humans are able to instantly retrieve little accessed information, despite the lack of anything like an addressing system or an indexing system in the brain;
  5. the problem of how humans are able to produce great works of creativity and imagination;
  6. the problem of how humans are able to be conscious at all;
  7. the problem of why humans have such a large variety of paranormal psychic experiences and capabilities such as ESP capabilities that have been well-established by laboratory tests, and near-death experiences that are very common, often occurring when brain activity has shut down;
  8. the problem of how humans have such diverse skills and experiences as mathematical reasoning, moral insight, philosophical reasoning, and refined emotional and spiritual experiences;
  9. the problem of self-hood and personal identity, why it is that we always continue to have the experience of being the same person, rather than just experiencing a bundle of miscellaneous sensations;
  10. the problem of intention and will, how is it that a mind can will particular physical outcomes.

It is therefore a ridiculous oversimplification for philosophers to be raising a mere "problem of consciousness” that refers to only one of these problems, and to be speaking as if such a “problem of consciousness” is the only difficulty that needs to be tackled by a philosophy of mind. But that is exactly what Philip Goff does in his book. We have an indication of his failure to pay attention to the problems he should be addressing by the fact that (according to his index) he refers to memory on only two pages of his book, both of which say nothing of substance about human memory or the problems of explaining it. His index also contains no mention of insight, imagination, ideas, will, volition or abstract ideas. The book's sole mention of the problem of self-hood or the self is (according to the index) a single page referring to “self, as illusion.” The book's sole reference to paranormal phenomena is a non-substantive reference on a single page. Ignoring the vast evidence for psi abilities, near-death experiences and other paranormal phenomena (supremely relevant to the philosophy of mind) is one of the greatest errors of academic philosophers of the past fifty years.

Imagine a baseball manager who has a “philosophy of winning baseball games” that is simply “make contact with the ball.” If you had such a philosophy, you would be paying attention to only a very small fraction of what you need to be paying attention to in order to win baseball games. And any philosopher hoping to advance a credible philosophy of mind has to pay attention to problems vastly more varied than a mere “problem of consciousness” or problem of why some beings are aware.

Goff's philosophical approach is to try and sell the old idea of panpsychism. Around for a very long time, panpsychism is the idea that consciousness is in everything or that consciousness is an intrinsic property of matter. A panpsychist may argue that just as mass is an intrinsic property of matter, consciousness is an intrinsic property of matter.  

As shown by psychology textbooks that may run to 500 pages, the human mind (including memory) is an incredibly diverse and complicated thing, consisting of a huge number of capabilities and aspects. It has always been quite an error when people try to describe so complicated a thing as something simple and one-dimensional.  This is what panpsychists have always done when they try to reduce the mind to the word "consciousness," which they then describe as a "property." A property is a simple aspect of something that can be described by a single number (for example, weight is a property of matter, and length is a property of matter, both of which can be stated as a single number).  A mind is something vastly more complicated than a property.  

Goff commits this same simplistic error by trying to shrink the human mind to the word "consciousness" throughout his book, and then telling us on page 23 that consciousness is a "feature of the physical world," and telling us on page 113 that "consciousness is a fundamental and ubiquitous feature of physical reality." When I look up "feature," I find that it is defined to mean the same thing as "property": "a distinctive attribue or aspect of something."  Human minds are vastly more complicated than any mere "feature" or "property" or "aspect" or "attribute."  We are being fed simplistic pablum when we are told that our minds are some "feature" or "aspect" or "property." If you've started out with the vast diversity and extremely multifaceted richness of the human mind, and somehow ended with up a one-dimensional word such as "feature" or "aspect" or "property,"  you've gone seriously wrong somewhere. Call it a shrinkage snafu. 

So many professors act like masters of concealment by acting in so many ways to misrepresent the gigantic mental and biological complexity of human beings, as if they were so interested in covering up our complexities.   And so we always have utterly misleading cell diagrams included in our biology textbooks, which make it look like there are only a few organelles per cell (the paper here tells us that there are typically hundreds or thousands of organelles per cell). And so we have "cell types" diagrams, which make it look as if there are only a few types of cells (the human body actually has hundreds of types of cells). And so we have the false myth that DNA is a blueprint or a recipe for making humans,  false not only because of the lack of any such human specification in DNA, but also because of the naive error of speaking as if you could ever build an ever-changing supremely dynamic organism like a human (as internally dynamic as a very busy factory) through some mere recipe or mere blueprint like you would use to construct a static house or a static piece of food.  And so we have the complexity-concealing claim that the vastly organized systemic arrangements of the human body can be explained by the "stuff piles up" idea of the accumulation of mutations (as if something as complex as a city could be explained by something like what we use to explain snow drifts). And so we have the frequent reality-denying assertions that mentally humans are "just another primate" or that other mammals are "just like us." And so you have the great complexity concealment of speaking as if a human mind was mere awareness or consciousness that could be described as a "property" or "feature." 

Panpsychism creates the problem that we have to then end up believing that all kinds of inanimate things are conscious to some degree. If consciousness were to be some intrinsic property of matter, it would seem to follow that the more matter, the greater the consciousness. So we would have to believe that the large rocks in Central Park of New York City are far more conscious than we are. And we would also have to believe that the Moon is vastly more conscious than we are. But if such inanimate things are far more conscious than we are, why do they not give us the slightest indication that they are conscious? There is no sign of any intelligent motion in the comets or asteroids that travel through space. Instead they seem to operate according to purely physical principles, just exactly as if they had no consciousness whatsoever. That's why astronomers can predict very exactly how closely an asteroid will pass by our planet, and the exact day that it will pass by our planet. So it seems that Goff's claim on page 116 that panpsychism is “entirely consistent with the facts of empirical science” is not actually true. To the contrary, we see zero signs of any consciousness or will in any non-biological thing, no matter how great its size, contrary to what we would expect under the theory of panpsychism.

On page 113 Goff suggests that maybe it is just certain arrangements of matter that might be conscious.  Goff isn't being terribly clear when he tells us on page on page 113, "Most panpsychists will deny that your socks are conscious, while asserting that they are ultimately composed of things that are conscious." So what does that mean, that the threads of your socks are conscious? If a panpsychist tries to defend his beliefs by denying that all material things are conscious, this actually pulls the legs from out under the table of panpsychism, depriving it of any small explanatory value it might have.  Once you go from "all matter is conscious" to "only certain arrangements of matter," you still have the same problem in materialism, that there is no reason anyone can see why consciousness would appear from some particular arrangement of matter. 

It would seem that the panpsychist has a kind of dilemma: either maintain that consciousness is an intrinisc property of matter (leaving you perhaps with some very small explanatory power, but many absurd consequences such as large rocks being more conscious than humans), or maintain that only special arrangements of matter are conscious (which would seem to remove any explanatory reason for believing in panpsychism in the first place). 

On page 150 to 153 Goff shows himself to be an uncritical consumer of one of the biggest legends of neuroscience, that split-brain patients have a dual consciousness. They have no such thing, as we can discover by watching Youtube interviews with split-brain patients who clearly have a single self. A scientific study published in 2017 set the record straight on split-brain patients. The research was done at the University of Amsterdam by Yair Pinto. A press release entitled “Split Brain Does Not Lead to Split Consciousness” stated, “The researchers behind the study, led by UvA psychologist Yair Pinto, have found strong evidence showing that despite being characterised by little to no communication between the right and left brain hemispheres, split brain does not cause two independent conscious perceivers in one brain.” The actual facts about split-brain surgery are related here by a surgeon who has performed such an operation. He states this about split-brain patients:

"After the surgery they are unaffected in everyday life, except for the diminished seizures. They are one person after the surgery, as they were before."

Panpsychism does very little to help with the explanatory problems in the philosophy of mind. The main reason is that it does not help with more than one of the ten problems listed at the beginning of this post. For example, panpsychism is worthless in explaining how humans are able to instantly retrieve memories, or why humans are able to form abstract ideas.

In the last paragraph of the book, Goff makes a pitch that kind of follows that classic salesman's advice to “sell the sizzle not the steak.” He states the following (imagine some violins playing as you read this passage):

Panpsychism offers a way of 're-enchanting the universe.' On the panpsychist view, the universe is like us; we belong in it. We need not live exclusively in the human realm, ever more diluted by globalization and consumerist capitalism. We can live in nature, in the universe. We can let go of nation and tribe, happy in the knowledge that there is a universe that welcomes us.”

But I fail to see any reason why a belief in panpsychism would produce any good change in human behavior. I can also imagine it having a bad effect. If you believe that all matter is conscious, you might have no particular guilt about killing someone. You might think to yourself: “He will still be conscious, even if I kill him, because all matter is conscious.” Similarly, if you believe that all matter is conscious, you might think it would be no great tragedy if all humanity were to become extinct, on the grounds that this would produce only a slight reduction in the total consciousness that exists in the universe (humanity having less than .0000000000000000000000000000000000001 of the universe's matter).

When panpsychists use simplistic shrinkage to describe mind as a mere "property" or "feature," it is like someone telling you that New York City is just a geographical coordinate, or like someone telling you that Brazil is just a pair of sounds someone can make with his mouth. 

Postscript: After writing this post, I found that Scientific American has an interview with Goff about his book. In the interview I didn't find anything to change my opinion about his ideas. Goff states the following;

"The basic commitment is that the fundamental constituents of reality—perhaps electrons and quarks—have incredibly simple forms of experience. And the very complex experience of the human or animal brain is somehow derived from the experience of the brain’s most basic parts."

We can try to imagine such a whimsical possibility. A quark might have an experience of a dull, static existence stuck inside an atomic nucleus. An electron might have an experience of constantly whizzing around a nucleus at incredible speeds, like some person stuck on an amusement park ride. Or a neuron might have an experience of just sitting there motionless inside a brain.  If there were billions or trillions or quadrillions of such tiny micro-experiences, they would never add up to anything like the experience of being a mobile thinking human free to walk around anywhere he wishes.

In a later article Goff makes an attempt to sell panpsychism as an "interpretation of physics." No, panpsychism is a position in the philosophy of mind. In listing alternative positions in the philosophy of mind, he fails to list one of the main positions (idealism, that only minds exist), and also fails to list another of the main positions (materialism, that all that exists is matter). He incorrectly describes dualism as the belief that "Physical reality is pure mathematical structure, but there is also non-physical consciousness." Dualism does not involve any claim that physical reality is a pure mathematical structure. 

Goff then defines panpsychism as if it were idealism, claiming that panpsychism is the position that "there are only conscious entities, and some of them realise the mathematical structures identified by physical science." This is not how panpsychism is typically defined when you look for a definition of it. The position that there are only conscious entities is idealism, not panpsychism. Wikipedia.org defines panpsychism as "the view that mind or a mindlike aspect is a fundamental and ubiquitous feature of reality."

An idealist believes that rocks only exist as things perceived within the experience of minds such as humans or God, but a panpsychist has typically been described as someone who thinks that a rock has a little bit of mind by itself. Is Goff trying to sell us idealism under the name of panpsychism? 

Using "according to panpsychism" where he should be using "according to me," Goff makes the statement below:

"According to panpsychism, an electron doesn’t have two kinds of property: physical and non-physical. Rather, it’s [sic] physical properties (mass, spin, charge) are forms of consciousness." 

I can only describe such a statement as the most nonsensical gibberish. Forms of consciousness include states such as (1) dreaming, (2) the half-dreaming state sometime occurring just after waking; (3) normal relaxed awareness; (4) the intense concentration of a test taker; (5) the trance state of mediums or clairvoyants or the hypnotized; (6) the altered mind state of some drug users; (7) the altered mind state of someone undergoing a near-death experience. Each such state varies between one person and another. Every electron has exactly the same mass, and every electron has exactly the same charge. Such things are no more "forms of consciousness" than my breakfast is a plan for obtaining world peace.

The Dismal Scenario Called Panpsychism

In academic circles it is commonly assumed that consciousness is generated by the brain. But many philosophers have been dissatisfied with this idea. Why is it that some particular arrangement of matter would cause Mind (a totally different type of thing) to emerge from the matter in a brain? To many that seems no more plausible than the idea that some particular arrangement of crystals in a rock might cause the rock to gush out blood.

One alternate idea is to assume that we have something like a soul, and that our mental experiences are produced not mainly by matter (the brain), but by something that is itself mental or spiritual. Another alternative (called idealism or immaterialism) is to believe that everything is mental, and that matter only exists as perceptions within minds.  A third alternative is the idea that the brain doesn't actually produce our minds, but somehow taps into some great external reality that is the source of our minds, perhaps in a way rather similar to how a television set receives TV signals, or how a smartphone connects with the internet. 

Yet another alternate idea is the radical notion known as panpsychism. Panpsychism has been described as the idea that consciousness is in everything.

This idea may not seem very unreasonable if we think of consciousness as some very simple thing. But the word “consciousness” describes only one aspect of human mentality, and there are many different aspects of the human mind. The visual below reminds us of the many aspects of mentality.


human mentality

I doubt whether panpsychism theorists have thought out which of these aspects of mentality they think should be attributed to “all matter.” Below are some questions I would ask a panpsychist:
  1. How could dead matter be said to have consciousness or mind, when objects such as rocks, atoms and electrons do not have sensory organs? Do you maintain that such objects have some existence like some person born blind and deaf into the world, who also had some brain defect preventing a sense of touch?
  2. How would self-hood work under a scenario in which all matter is conscious? Is the Pacific ocean a single conscious self? Or is every drop of water its own conscious self? Or is there perhaps some particular unit of matter (such as a liter) which causes some quantity of water to achieve self-hood?
  3. Does each atom on a beach have its own self-hood, or does it take a grain of sand to make a sand self? Or does perhaps the whole beach constitute a single self?
  4. Do you maintain that lifeless objects have volition, the ability to will particular actions? If so, how do you reconcile such a belief with the complete lack of any evidence that lifeless matter is engaging in volition or willing actions?
  5. Do you maintain that lifeless objects have memories or thoughts? If you think they have either, how could that be, since thoughts require language (which could not be known by minds without sensory experience), and memories require either thoughts or sensations (which would seem to be impossible for a mind without sensory experience)?
  6. Do you maintain that lifeless objects have interests, pleasures, pains, attitudes, knowledge or ideas? How could lifeless objects have such things if they never had sensory experience?

Of course, once we consider such questions we become entangled in a great ocean of difficulties. Let us consider the question of volition, which means the power to carry out some action. There are two possibilities for a panpsychist. The first (call it option A) is to maintain that lifeless objects can carry out actions by willing them. One problem with this option is that lifeless objects do not have sensory organs. So we can't really imagine any reasonable scenario by which a lifeless natural object would will something to occur. For example, if a lifeless asteroid were traveling through the solar system, we cannot imagine it willing itself to move closer to the Earth, because lacking all sensory organs, such a rock would never know what Earth (or anything else) was.

Another strong reason for rejecting option A is that there is zero evidence that lifeless objects can will things. For example, on the subatomic level, subatomic particles such as electrons and protons act with unvarying precise obedience to the laws of electromagnetism. If they did not, you would not be reading a coherent intelligible essay at this moment, but would be seeing only a jumbled scramble of pixels. To give another example, astronomers find that things such as asteroids and comets act with unvarying precise obedience to the laws of gravity, showing no signs of independence.

So it seems option A doesn't work. The alternative for a panpsychist considering this question of volition in lifeless objects is what we may call option B: the idea that lifeless objects with minds do not have any power of volition. But when we think about this possibility, it seems very depressing. Given their lack of sensory organs, lifeless objects with a mind would be like a child born deaf, blind and incapable of any tactile sensation. If we also imagine them having no power of volition, we then imagine them like a child born completely paralyzed, blind, deaf and incapable of feeling touch.

So option B seems like quite a dismal scenario. If we have a universe filled with 1,000,000,000,000,000,000,000,000,000,000 conscious objects that are like children born deaf, blind, paralyzed and without any sense of smell, taste or touch, that is a dismal and repulsive scenario. The scenario becomes even more dark and depressing when we ask ourselves: how long would these conscious but lifeless objects live? The answer would apparently be: in many cases, for billions of years. So, for example, if you were a conscious rock on the moon, you would have to hang around for billions of years in such an undesirable state: blind, deaf, and paralyzed, unable to communicate with your fellow rocks, unable to do anything. The panpsychist apparently must believe that for every conscious human such as yourself who can exercise volition and enjoy sensory experience, there are 1,000,000,000,000,000 or more conscious entities living a horrid life of blindness, deafness and paralysis.

thinking rock

You might avoid such problems by believing that consciousness is in all matter, but that such consciousness consists of a single cosmic mind self.  But that version of panpsychism would seem to do nothing to help explain how humans have minds.  If your brain is merely a millionth of a billionth or a trillionth of .000000000000000000000000000000000000001 percent of the matter that gives rise to some single cosmic mind, that would not at all seem to imply that you should have a mind because of that tiny fraction.  

A writer named Daniel Podgorski recently wrote a post entitled "A Scientific Defense of Panpsychism."  The subtitle of his post was "Understanding Panpsychism through Evolutionary Biology and an Analogy to Electricity."  He states the following:

Yet only extremely recently, in the 1800s, did the science of electromagnetism (born in that century from the distinct studies of electricity and magnetism) advance far enough to allow for the explosion of inventions whereby electricity has been harnessed to run a staggering proportion of the tools with which we live, work, and play daily. Electricity was already out there in the world, existing and happening. But only within certain arrangements of matter can electricity do things which are interesting and useful to human beings. My take on panpsychism is that consciousness is similar. It is out there in the world everywhere and it always has been, but only in certain arrangements of matter does it seem to really do anything.

There are several reasons why this analogy is fallacious:

(1) Electricity is something required by complex electrical machines, but it does not at all by itself give rise to the useful work they do.  When electrical machines do things, it is incorrect to describe this as electricity doing things.  Volts don't take me from Queens to Manhattan; a subway does. 
(2) Electrical machines are designed products, but an evolutionary biologist does not believe that a brain is a designed product.
(3)  Electrical machines such as computers can do data processing, but they do not have consciousness or understanding, and a computer does not have self-hood. 
(4) It is fallacious to speak as if work done by an electrical machine is a case of something latent in a machine being unleashed. When my fan runs, it is not because some inherent electricity in the machine is being unleashed; it is because the machine is connecting to a very complicated external power grid. 
(5) Mechanical work (a physical moving about of things) bears no resemblance to the aspects of human mentality (which are mental, non-physical things). So if we know that some latent thing inside physical things could give rise to mechanical work, that would do nothing to make it more likely that some latent thing inside a physical thing could give rise to mental phenomena.

The author Julie J. Morley advocates panpsychism in the recent book Future Sacred: The Connected Creativity of Nature.  Morley's approach is largely to just cite philosophers who advocated for panpsychism. On page 142 she claims that "sentience exists on every scale." She doesn't seem to put up much of any real philosophical argument for panpsychism, although on page 77 she cites approvingly "nine core arguments for panpsychism" advanced by an author named David Skrbina.  The arguments are as follows (the quotes paraphrasing these arguments are from Morley's book):

(1) "Indwelling power. All objects exhibit certain powers or abilities that can be plausibly linked to noetic qualities."  This claims is invalid; for example, rocks do not exhibit any such powers or abilities. 
(2) "Continuity. A common principle or substance exists in all things." Not much of an argument, because we can believe that such a common principle or substance is not a mental principle or substance. 
(3) "First principles. Mind is posited as a fundamental and universal quality, present in all things." This isn't an argument for panpsychism, but just a statement of the idea of panpsychism.
(4) "Design. The inherent self-organizing capacity of physical processes suggests the possibility, if not the likelihood or necessity, of some purposeful intelligence (entelechy) active throughout the physical world."  There is no known inherent self-organizing capacity of physical processes. There are things (such as fine-tuned physical constants and fine-tuned biology) which may suggest the likelihood of some purposeful intelligence active throughout the physical world, but you can believe in such an intelligence without believing in panpsychism. 
(5) "Nonemergence. It is inconceivable that mind should emerge from wholly mindless matter." The implausibility of such a thing argues against materialism, but does not argue specifically for panpsychism. There are still the possibilities of dualism and idealism (immaterialism) if mind cannot emerge from matter. 
(6) "Theology. Omnipresent God, understood as universal 'mind' or 'spirit,' exists in all things."  That is an assertion, not an argument. 
(7) "Evolution....Certain objects (e.g. plants and the Earth) share a common dynamic or physiological structure with human beings, and thus possess mind."  I deny that there is any common dynamic or physiological structure shared by rocks or rocky bodies (such as the Earth and the moon) and human beings. Even plants don't really have any common physiological structure or dynamic with humans. 
(8) "Dynamic sensitivity. Living systems...respond dynamically to changes in the environment. This inherent responsiveness implies 'sensitivity' -- an ability to feel and be aware of its surroundings." This could be used to argue that all living things have some kind of consciousness, but does not support the idea that lifeless things such as rocks have consciousness.
(9) "Authority. Major intellectuals have expressed an intuitive or rational belief in some form of panpsychism." The same type of reasoning could be used for almost any belief that was ever advocated in a book. 

On page 157 of her book, Morley tells us that sentience is "inseparable from matter" and that matter and mind are "inseparably coupled." This does not match the empirical evidence. It is very common in near-death experiences for someone to report floating out of his body and observing his body from above it.  In many such cases a person who should have been unconscious will correctly report observations he should have been unable to have  observed while unconscious.  Such experiences suggest quite the opposite of a dogma that mind is inseparable from matter. Speaking of life-after-death, since a panpsychist believes that all matter is conscious, and that mind is inseparable from matter,  panpsychism would seem to imply the ghastly idea that corpses are conscious inside their coffins.  

Below are two very similar cases of reasoning, equally fallacious. One of them is panpsychism.

John: The matter in your brain creates your mind.
Bob: I don't believe it. Why would mere matter give rise to Mind, something totally different?
John: So let's just imagine that all matter is conscious. Then you should be able to believe that your brain makes your mind, or is your mind.
John: I have a rock in my backyard that can levitate.
Bob: I don't believe you. A rock could never levitate.
John: So let's just suppose that all rocks can levitate. Then you should be able to believe that the rock in my backyard can levitate.

He Tries to Pump Some "Star Wars" Glamour into Panpsychism

In his post “Why Panpsychism is the Jedi Philosophy,” BigThink.com columnist Scott Hendricks starts out by describing the Force, the mysterious cosmic energy source depicted in the Star Wars movies. Here is how Obi-Wan Kenobi first describes the Force in the first Star Wars movie:

The Force is what gives a Jedi his power. It's an energy field created by all living things. It surrounds us and penetrates us; it binds the galaxy together.

Yoda the Jedi master of the Force explains it this way: “Life creates it, makes it grow. Its energy surrounds us and binds us."

After describing the Star Wars depiction of the force, Hendricks says, “There is a name for this philosophy in real life, panpsychism.” But Hendricks errs. The depiction of the Force in the Star Wars movies is not any statement of the philosophy of panpsychism.

Panpsychism is the idea that all matter is to some degree conscious. But the Star Wars idea of the Force is not an idea about matter.  It is an idea about a cosmic energy. No one in the Star Wars movies ever makes the panpsychist claim that all matter is conscious, nor does any such character claim that any nonliving material thing is conscious.

Hendricks incorrectly describes how the Force is depicted in the Star Wars movies. He tells us, “While only some things, notably Force-sensitive characters, can manipulate the Force, every object in the universe appears to be able to interact with the Force.” He provides a link to try to back up this claim, which merely takes us to the first description of the Force in the Star Wars movies:

The Force is what gives a Jedi his power. It's an energy field created by all living things. It surrounds us and penetrates us; it binds the galaxy together.

But that quote does not at all back up the claim that “every object in the universe appears to be able to interact with the Force,” an idea never presented in the Star Wars movies. To the contrary, the two quotes above (by Obi-Wan Kenobi and Yoda) tell us that the force is created specifically by living things, not by material things in general. 

Poster of the latest Star Wars movie

In the Star Wars movies, the Force is associated with psychic powers such as telepathy and psychokinesis. The masters of the Force known as Jedi can influence the minds of others through thought suggestion, as Obi-Wan Kenobi does when he gets out of a jam by telepathically influencing the mind of a security guard. A Jedi can also sense distant important events by sensing a disturbance in the Force, as Obi-Wan does when he detects a “great disturbance in the Force” when the Death Star destroys a distant planet. A Jedi can even use the force to move objects such as a light saber. Someone can also use the Force to achieve things he could never normally do, such as when Luke Skywalker uses the Force to help him perform the difficult task of blowing up the Death Star.

None of this has anything to do with panpsychism, and panpsychism is not associated with any claims or beliefs about psychic powers. Panpsychism has never been associated with any types of claims about a cosmic force, mysterious or non-mysterious.

From the table below we can see there is basically nothing that panpsychism has in common with the Star Wars concept of the Force.



Panpsychism Star Wars concept of the Force
Make a claim about matter? Yes No
Claims all matter is conscious? Yes No
Makes a claim about a cosmic energy field? No Yes
Makes a claim about psychic powers (telepathy, psychokinesis)? No Yes
Differentiates between living and non-living things? No Yes (the Force is described as a product of all living things, not all matter)
Suggests some cosmic will? No Yes (“will of the Force” in episode 1)
Associated with post-mortal survival? No Maybe (ghost of Obi-Wan Kenobi twice seen)

Although the Star Wars movies tell us nothing about how the Force might relate to life-after-death, the movies hint that there may be such a relation. In Episode 4 we hear the voice of the deceased Obi-Wan Kenobi telling Luke Skywalker to “use the force.” In Episode 5 we see the ghost of Obi-Wan Kenobi appearing to Luke Skywalker. In Episode 6 we the ghost of Obi-Wan Kenobi, Darth Vader and Yoda all appearing to Luke Skywalker. Since these were all great masters of the Force, we can infer some relation between the Force and their post-mortal survival.

Hendrick's attempt to glamorize panpsychism by calling it “the Jedi philosphy” is erroneous. If we want to find philosophical ideas that partially mirror the metaphysics of Star Wars, the two below are much better matches:

Vitalism: Vitalism is the idea that there is some mysterious life force involved with all living things. This sounds a little like the claim twice made in the Star Wars movies that the Force is created by all living things.
Spiritualism: Spiritualism is the idea that people survive death, and can communicate with the living. When the deceased Obi-Wan Kenobi communicates to Luke Skywalker in Episode 4 and Episode 5 of the Star Wars series, this is very much a fictional expression of the idea of spiritualism. 

Panpsychism is largely an attempt to help deal with the problem that there is no apparent reason why the neurons in a brain could ever generate a mind such as humans have.  The panpsychist kind of tells us that such a thing is not so unthinkable, because every little neuron (and every other little thing) is a tiny bit conscious. The problem is that similar reasoning would lead us to believe that the boulders at the seashore or the trees in the forest have bigger minds than we have, since they have even more material particles than are in our brains.  A better way to deal with the "How could minds arise from brains?" problem is to simply conclude: they don't.  The claim that minds arise from brains has been asserted countless times, but never proven.  There are good reasons for doubting such a claim, as you will sometimes read about on this blog.

It's More Likely That Everything Is in Consciousness Than That Consciousness Is in Everything

In academic circles it is commonly assumed that consciousness is generated by the brain. But some philosophers have been dissatisfied with this idea. Why is it that some particular arrangement of matter would cause Mind (a totally different type of thing) to emerge from that matter? To many that seems no more plausible than the idea that some particular arrangement of crystals in a rock might cause the rock to gush out blood.

One alternate idea is to assume that we have something like a soul, and that our mental experiences are produced not just by matter (the brain), but something that is itself spiritual. Another alternate idea is the radical notion known as panpsychism. Panpsychism is basically the idea that consciousness is in everything.

A panpsychist might believe that every piece of matter is in some sense conscious. At first this may seem to help in explaining how brains can produce consciousness. If every neuron is a little bit conscious, it might explain why billions of cells in the brain can produce consciousness.

But it does not seem that there is any evidence that little pieces of matter are conscious. Electrons seem to behave with complete predictability according to the laws of electromagnetism, not as if they were semi-conscious little things with wills of their own. And oxygen molecules do not act as if they had some interest in their surroundings. When you enter an empty room, you do not feel a gush of wind coming your way, as you might feel if the air molecules were interested in seeing who was entering the room.

Panpsychism seems rather inconsistent with theism. Consider the moon. The idea that the moon is conscious may have a certain appeal. But imagine all those rocks on the moon's surface, lying there for billions of years. Think of what torture it would be if such rocks were actually conscious – they would have to suffer billions of years of absolute boredom, just sitting there with nothing to observe or experience. It would be hard to think of a reason why any deity would wish to endow such rocks with consciousness, to suffer such billion-year boredom and stagnation. And what about all the rocks and little pieces of matter underneath the surface of the moon and other planets, who would have the dullest experiences imaginable for billions of years?

I'm not sure we would want to believe that all the little pieces of matter around us are conscious. Do you want to believe that every time you walk on the autumn leaves, that you are crushing conscious beings underneath your foot? And if you accepted panpsychism, it would seem that every time you bake some cookies, you would have to worry about slowly torturing the poor conscious little cookies. 

panpsychism

An alternative to panpsychism, and something equally as radical, is the philosophical doctrine of idealism. Rather than maintaining that consciousness is in everything, an idealist maintains that everything is in consciousness.

An idealist maintains that the only thing that exists are different types of minds, and that material things only exist in the sense that they are elements within the mental experiences of minds. Perhaps the best way to explain this idea to the modern person is to consider what goes on in a video game. Suppose you are playing some Star Wars video game in which you are trying to blow up the Death Star. Now to what extent does this Death Star exist? It has no physical existence outside of the game world. The Death Star exists as a shared perception, something that is seen by all of the players of the video game under certain conditions. Similarly, an idealist may believe that Earth's moon has no physical existence outside of minds. According to such a person, our moon only exists as a shared perception within the mental experience of humans. An idealist thinks that if somehow all minds were to be destroyed, there would be no more moon.

So the idealist believes that the sole reality of physical things we perceive is their reality inside our minds. To such a person, the history of the universe is simply a history of mental experiences; and there was no state of the universe in which matter existed before minds.

There is no way to prove this philosophical doctrine, but there are no observations that we could ever have that would disprove this idea. Think about it. Every single observation or measurement we can make can be boiled down to a human experience. If you see a rock, that's a human experience. If you weigh the rock, that's also a human experience. If you measure the rock with a measuring rod, or determine its chemical content using a mass spectrometer, that's also a human experience. There is no way to verify that the rock exists outside of human experience.

Any credible theory of idealism requires a belief in some higher agent that acts to assure that there are certain consistencies in human experiences. But since idealism ends up removing quite a few dilemmas and difficulties in the “first matter, then mind” story of the universe, idealism ends up being at least as credible as any other philosophical worldview. A surprisingly compelling case for idealism was made in the 18th century by the British philosopher George Berkeley.

Today idealism is rather unfashionable, but in certain circles it is fashionable to speculate that we are just items in some computer simulation created by extraterrestrials. But the underlying concept is quite similar – that the things we perceive do not exist independently of our experiences, and that there is some external reality guaranteeing that we have certain common perceptions (such as the perception of the moon when we look up at night), rather than each of us having totally unique mental experiences.

But if you maintain that we are participants in some computer simulation crafted by extraterrestrials, you haven't removed any explanatory difficulties. The vexing problem is how is it that Mind can arise from matter, a totally different type of thing. With idealism such as advanced by Berkeley, that problem is removed, for you end up with the doctrine that there are only minds. But with some extraterrestrial simulation theory, the explanatory problem becomes twice as bad. For the theory maintains that biological matter gave rise to one type of minds (extraterrestrial minds), and that such minds then produced electronic matter that give rise to our minds. With that theory, you have two types of “Mind from matter” difficulties.

Both panpsychism and idealism are rather radical philosophical doctrines, and we are not forced to choose between the two. But if I had to choose between the belief that consciousness is in everything (panpsychism), and the belief that everything is in consciousness (idealism), I would choose the second of these. I don't care to believe that my cookies are suffering when I bake them.
