Without getting into the topic of outright fraud, we know of many common problems that afflict a sizable percentage of scientific papers. One is that it has become quite common for scientists to use titles for their papers announcing results or causal claims that are not actually justfied by any data in the papers. A scientific study found that 48% of scientific papers use "spin" in their abstracts. Another problem is that scientists may change their hypothesis after starting to gather data, a methodological sin that is called HARKing, which stands for Hypothesizing After Results are Known. An additional problem is that given a body of data that can be analyzed in very many ways, scientists may simply experiment with different methods of data analysis until one produces the result they are looking for. Still another problem is that scientists may use various techniques to adjust the data they collect, such as stopping data collection once they found some statistical result they are looking for, or arbitrarily excluding data points that create problems for whatever claim they are trying to show. Then there is the fact that scientific papers are very often a mixture of observation and speculation, without the authors making clear which part is speculation. Then there is the fact that through the use of heavy jargon, scientists can make the most groundless and fanciful speculation sound as if was something strongly rooted in fact, when it is no such thing. Then there is the fact that scientific research is often statistically underpowered, and very often involves sample sizes too small to be justifying any confidence in the results.
All of these are lesser sins. But what about the far more egregious sin of outright researcher misconduct or fraud? The scientists Bik, Casadevall and Fang attempted to find evidence of such misconduct by looking for problematic images in biology papers. We can imagine various ways in which a scientific paper might have a problematic image or graph indicating researcher misconduct:
(1) A photo in a particular paper might be duplicated in a way that should not occur. For example, if a paper is showing two different cells or cell groups in two different photos, those two photos should not look absolutely identical, with exactly the same pixels. Similarly, brain scans of two different subjects should not look absolutely identical, nor should photos of two different research animals.
(2) A photo in a particular paper that should be different from some other photo in that paper might be simply the first photo with one or more minor differences (comparable to submitting a photo of your sister, adjusted to have gray hair, and labeled as a photo of your mother).
(3) A photo in a particular paper that should be original to that paper might be simply a duplicate of some photo that appeared in some previous paper by some other author, or a duplicate with minor changes.
(4) A photo in a particular paper might show evidence of being Photoshopped. For example, there might be 10 areas of the photo that are exact copies of each other, with all the pixels being exactly the same.
(5) A graph or diagram in a paper that should be original to that paper might be simply a duplicate of some graph or diagram that appeared in some previous paper by some other author.
(6) A graph might have evidence of artificial manipulation, indicating it did not naturally arise from graphing software. For example, one of the bars on a bar graph might not be all the same color.
There are quite a few other possibilites by which researcher misconduct could be identified by examining images, graphs or figures. Bik, Casadevall and Fang made an effort to find such problematic figures. In their paper "The Prevalence of Inappropriate Image Duplication in Biomedical Research Publications," they report a large-scale problem. They conclude, "The results demonstrate that problematic images are disturbingly common in the biomedical literature and may be found in approximately 1 out of every 25 published articles containing photographic image data."
But there is a reason for thinking that the real percentage of research papers with problematic images or graphs is far greater than this figure of only 4%. The reason is that the techniques used by Bik, Casadevall and Fang seem like rather inefficient techniques capable of finding only a fraction of the papers with problematic images or graphs. They describe their technique as follows (20,621 papers were checked):
"Figure panels containing line art, such as bar graphs or line graphs, were not included in the study. Images within the same paper were visually inspected for inappropriate duplications, repositioning, or possible manipulation (e.g., duplications of bands within the same blot). All papers were initially
screened by one of the authors (E.M.B.). If a possible problematic
image or set of images was detected, figures were further examined
for evidence of image duplication or manipulation by using the
Adjust Color tool in Preview software on an Apple iMac computer. No additional special imaging software was used. Supplementary figures were not part of the initial search but were examined in papers in which problems were found in images in the
primary manuscript."
This seems like a rather inefficient technique which would find less than half of the evidence for researcher misconduct that might be present in photos, diagrams and graphs. For one thing, the technique ignored graphs and diagrams. Probably one of the biggest possibilites of misconduct is researchers creating artificially manipulated graphs not naturally arising from graphing software, or researchers simply stealing graphs from other scientific papers. For another thing, the technique used would only find cases in which a single paper showed evidence for image shenanigans. The technique would do nothing to find cases in which one paper was inappropriately using an image or graph that came from some other paper by different authors. Also, the technique ignored supplemental figures (unless a problem was found in the main figures). Such supplemental figures are often a signficant fraction of the total number of images and graphs in a scientific paper, and are often referenced in the text of a paper as supporting evidence. So they should receive the same scrutiny as the other images or figures in a paper.
I can imagine a far more efficient technique for looking for misconduct related to imagery and graphs. Every photo, every diagram, every figure and every graph in every paper in a very large set of papers on a topic (including supplemental figures) would be put into a database. A computer program with access to that database would then run through all the images, looking for duplicates or near-duplicates in the images, as well as other evidence of researcher misconduct. Such a program might also make use of "reverse image search" capabilities available online. Such a computer program crunching the image data could be combined with manual checks. Such a technique would probably find twice as many problems. Because the technique for detecting problematic images described by Bik, Casadevall and Fang is a rather inefficient technique skipping half or more of its potential targets, we have reason to suspect that they have merely shown us the tip of the iceberg, and that the actual rate of problematic images and graphs (suggesting researcher misconduct) in biology papers is much greater than 4% -- perhaps 8% or 10%.
A later paper ("Analysis and Correction of Inappropriate Image Duplication: the Molecular and Cellular Biology Experience") by Bik, Casadevall and Fang (along with Davis and Kullas) involved analysis of a different set of papers. The paper concluded that "as many as 35,000 papers in the literature are candidates for retraction due to inappropriate image duplication." They found that 6% of the papers "contained inappropriately duplicated images." They reached this conclusion after examining a set of papers in the journal Molecular and Cellular Biology. To reach this conclusion, they used the same rather inefficient method of their previous study I just cited. They state, "Papers were scanned using the same procedure as used in our prior study." We can only wonder how many biology papers would be found to be "candidates for retraction" if a really efficient (partially computerized) method was used to search for the image problems, one using an image database and reverse image searching, and one checking not only photos but also graphs, and one also checking the supplemental figures in the papers. Such a technique might easily find that 100,000 or more biology papers were candidates for retraction.
We should not be terribly surprised by such a situation. In modern academia there is relentless pressure for scientists to grind out papers at a high rate. There also seems to be relatively few quality checks on the papers submitted to scientific journals. Peer review serves largely as an ideological filter, to prevent the publication of papers that conflict with the cherished dogmas of the majority. There are no spot checks of papers submitted for publication, in which reviewers ask to see the source data or original lab notes or lab photographs produced in experiments. The problematic papers found by the studies mentioned above managed to pass peer review despite glaring duplication errors, indicating that peer reviewers are not making much of an attempt to exclude fraud. Given this misconduct problem and the items mentioned in my first paragraph, and given the frequently careless speech of so many biologists, in which they so often speak as if unproven claims or discredited claims are facts, it seems there is a significant credibility problem in academic biology.
Postscript: In an unsparing essay entitled "The Intellectual and Moral Decline in Academic Research," PhD Edward Archer states the following:
"My experiences at four research universities and as a National Institutes of Health (NIH) research fellow taught me that the relentless pursuit of taxpayer funding has eliminated curiosity, basic competence, and scientific integrity in many fields. Yet, more importantly, training in 'science' is now tantamount to grant-writing and learning how to obtain funding. Organized skepticism, critical thinking, and methodological rigor, if present at all, are afterthoughts....American universities often produce corrupt, incompetent, or scientifically meaningless research that endangers the public, confounds public policy, and diminishes our nation’s preparedness to meet future challenges....Universities and federal funding agencies lack accountability and often ignore fraud and misconduct. There are numerous examples in which universities refused to hold their faculty accountable until elected officials intervened, and even when found guilty, faculty researchers continued to receive tens of millions of taxpayers’ dollars. Those facts are an open secret: When anonymously surveyed, over 14 percent of researchers report that their colleagues commit fraud and 72 percent report other questionable practices....Retractions, misconduct, and harassment are only part of the decline. Incompetence is another....The widespread inability of publicly funded researchers to generate valid, reproducible findings is a testament to the failure of universities to properly train scientists and instill intellectual and methodologic rigor. That failure means taxpayers are being misled by results that are non-reproducible or demonstrably false."

No, That Dead Tissue Study Didn't Show That Neurons or Dendrites Compute
When
you read news relating to neuroscience, you will typically read a
great deal of baloney and shameless hype. The first reason for this has to do
with the runaway hype and exaggeration that is currently going on in
regard to Internet sites reporting scientific research. Major
websites have learned the following fundamental formula:
Clicks=
Cash Income
The
reason for this is that major websites make money from online ads. So
the more people click on a link to some science story, the more money
the website makes. This means that science reporting sites have a
tremendous financial incentive to hype and exaggerate science
stories. If they have a link saying, “Borderline results from new
neuron study,” they may make only five dollars from that story. But
if they have a story saying, “Astonishing breakthrough unveils the
brain secret of memory,” they may make five hundred dollars from
that story. With such a situation, it is no wonder that the hyping
and exaggeration of scientific research is at epidemic levels.
Part
of the problem is university press offices, which nowadays are
shameless in exaggerating the importance of research done at their
university. A
scientific paper reached the following conclusions, indicating a huge
hype and exaggeration crisis both among the authors of scientific
papers and the media that reports on such papers:
“Thirty-four
percent of academic studies and 48% of media articles used language
that reviewers considered too strong for their strength of causal
inference....Fifty-eight percent of media articles were found to have
inaccurately reported the question, results, intervention, or
population of the academic study”
Another
giant reason for the baloney and hype in today's neuroscience news is
that neuroscientists simply aren't finding results that back up
dogmatic neuroscientist claims about the brain. Specifically:
- Neuroscientists are not finding any real evidence of any system of encoding by which human conceptual knowledge or episodic memories could be stored as neuron states or synapse states (nor do they even have any detailed theory to explain such a thing).
- Neuroscientists are not finding any legitimate evidence of specific learned knowledge stored anywhere in brains (such as learned knowledge that can be read from the brains of dead people or dead animals).
- Neuroscientists are not finding any evidence that could explain how a brain could think or imagine or create abstract ideas.
- Neuroscientists are not finding any evidence of how memories could be stored for decades, and their research is suggesting exactly the opposite, that brains are totally unsuitable for storing information for any length of time longer than a year (the average life of synapse proteins being only a few weeks).
- Neuroscientists are not finding any real evidence that brains look different during thinking or recall than during mental inactivity (brain scans showing no difference of more than half a percent).
- Neuroscientists are not finding any brain action that could explain the instantaneous formation of memories, which can form so much quicker than can be explained through "synapse strengthening" that would take quite some time.
So
what do our neuroscience news sources do when they don't have the
kind of research findings they would like to have? They hype like
crazy all kinds of dubious stuff. They take weak or faulty or
second-rate studies, and try to make them sound like “eureka”
breakthroughs.
An
example of this can be found in recent stories in the science news press claiming
that some evidence of computational ability had been found in neuron
or dendrites. The claim is false, and is based on research that found
no robust evidence of such a thing. One of the stories (in the online Quanta magazine) had
the title “Hidden Computational Power Found in the Arms of
Neurons.” The site Singularity Hub had a bunk headline of "Scientists Discovered ‘Mini-Computers’ in Human Neurons—and That’s Great News for AI." No such thing was actually found. The underlying study
was able to claim to find the barest trace of “computational power” only
after taking dead brain tissue, artificially zapping it with
electricity, and then plugging the resulting data into a computer
model, which we can assume was carefully programmed to allow such a report of "signs of computation" to be made. As I will explain,
someone could use similar techniques to report “computational
power” coming from any of many things as witless and non-computing as a stone.
The
study (behind a paywall) was the Science study “Dendritic action potentials and computation in
human layer 2/3 cortical neurons.” The two main types of
biological studies are in vivo studies (using an actual living organism), and
in vitro studies (merely using some dead specimen, or some tissue or cells
detached from an organism). The “dendritic action potentials”
study was an in vitro study. The study used brain tissue that had
been removed from human brains during brain surgeries conducted for
other purposes. There is a big reason why it makes no sense to be
making any claim about a computational ability of neurons from any
type of in vitro study using detached human brain tissue.
The
reason is that in an actual living brain, every neuron is connected
to many other neurons, and is constantly receiving signals from all
of those other neurons. It has been estimated that a typical neuron
is connected to thousands of other neurons. Each of these neurons is
constantly emitting electrical/chemical signals called action potentials. Although estimates of neuron firing rates vary, it
is typically estimated that each neuron sends out an action potential at
an average rate of once per second or more. All of this creates the most
gigantic noise issue, which should prevent reliable
computation from occurring in a brain.
We
may compare a neuron to a person on a stage in a very large theater
or auditorium, at a time when thousands of people in the audience are
all shouting at him. Just as it would be impossible for such a person
to hear a full sentence from even one of these voices, it should be impossible for any
neuron to have the type of noise exclusion needed
for effective computation, when each neuron is being flooded with
signals from hundreds or thousands of other neurons. Neurons and synapses are flooded with so much noise in such high amounts that they cannot be doing the things our neuroscientists like to hope they are doing. Neuroscientists pretty much ignore this gigantic "neural noise" problem, and turn a deaf ear to what nature is telling us in this regard.
If the whole audience was shouting at you, you'd be like a neuron
But
imagine you take some brain tissue out of the brain, and test that artificially, in vitro. Then by zapping a neuron with a single
electrode, you can get a nice clean situation in which all of those
signal bombardments are eliminated. But such a situation tells us
nothing about a real human brain. For it bears no resemblance to
what is going in a human brain in which each neuron is bombarded by
electrical signals from thousands of other neurons.
It
is just such an in vitro situation that was used by the “dendritic
action potentials” study, which got some data from zapping dead
brain cells rather than data from living human brains. The data they got
did not by itself indicate that anything like computation was
going on in the dead brain tissue that was tested.
So
the experimenters had to insert their data into something called a
computer model. A computer model is some computer program designed to
simulate physical reality. Of course, when we are dealing with the
near-infinite complexities of human biology, trying to simulate
things with computer models is pretty much a joke. You can get pretty
much anything you want to show from a computer model. You just
program things to favor the desired result.
The
study authors claim to have got a little evidence of computation, but merely some minimal couldn't-be-simpler computation called an “XOR” computation. They claim to have got this after they took their data
from zapping dead brain tissue, and plugged it into their computer
program. I may note that
you could use such an approach to yield such “evidence of
computation” from very many things which we regard as being as
mindless and non-computing as a stone.
I
will give an example. Below (according to the wikipedia article) is the truth table describing the simple-as-it-gets “XOR”
computation:
| Input | Output | |
| A | B | |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
I
could write a computer program to simulate coin flips. There would be
four possibilities: (1) a non-successful flip because the coin went down the flipper's shirt; (2) a
“heads” flip; (3) a “tails” flip; (4) the coin landing on its
edge, which can be considered both “heads” and “tails” (since
both sides of the coin can be seen). So now the truth table for this coin flipping would look
like the table below, and would resemble the table for the "XOR" computation:
| Input | Output (1= successful flip) |
Comment | |
| “Heads” | “Tails” | ||
| 0 | 0 | 0 | Coin lands in flipper's shirt |
| 0 | 1 | 1 | Coins lands “tails” |
| 1 | 0 | 1 | Coin lands “heads” |
| 1 | 1 | 0 | Coin lands on edge |
Using
such assumptions, I could simulate the flipping of coins in my
computer program. And what would my program suggest? Not very much,
but you might claim that such a program suggests that mindless coins can
compute. For in such a program, the mindless coin flipping is producing something rather like an
“XOR” operation (if we use the analysis above).
Of
course, such a program would be no real reason for thinking that a
coin can to any degree compute or think. And it would not give us any
reason for thinking that big sacks of coins are computing or
thinking, or that a whole bunch of coins jiggling around in some
machine would be producing anything like computation or thinking.
Similarly, studies done with dead brain tissue hooked up to electrodes (studies relying on plugging the data into a computer model designed to extract some sign of computation) don't prove that living neurons or dendrites can
compute.
Just as I have shown how you can do a computer model that seems to yield a little "XOR computation" from simulated coin flips, I could have shown how other computer models might seem to show "XOR" computation from numerous other inanimate mindless non-computing objects. The "dendritic action potentials" paper has produced no robust evidence of computation in the brain. Because
it used dead tissue rather than live brains, the “dendritic action
potentials” paper was rather like a study trying to prove that
gorillas can play baseball, not by doing experiments with live
gorillas, but by taking a baseball glove and sticking it on the hand of a dead gorilla, to see if you could pitch a ball into the glove of the dead gorilla without the ball falling out.
In reality, the human brain bears virtually no resemblance to a computer, and there is still no good evidence that the brain does anything like computation. Brains don't have any of seven major things that computers use to store and retrieve information. Computers compute by using software, and nothing like software exists in the brain. A non-metallic device without software doesn't seem like something that can be doing much in the way of computation. Someone who claims that a brain without software is "just like a computer" is like someone claiming that a wagon without an engine is "just like a car."

His “Spiritual Materialism” Is an Oxymoron
The
Templeton Prize is a huge monetary award of more than 1,400,000
dollars. The prize was established by John Templeton, an incredibly
successful investor who in his will gave a huge endowment to
the Templeton Foundation he had established. The Templeton
Foundation now has assets of more than 3 billion dollars, and gives
out lots of small grants as well as the big jackpot of the annual
Templeton Prize. Until 2001 the Templeton Prize was officially
called “the Templeton Prize for Progress in Relgion.” From 2002
to 2008 the Templeton Prize was officially called ”the Templeton
Prize for Progress Toward Research or Discoveries about Spiritual
Realities."
Nowadays
the Templeton Prize has no such official title other than the
Templeton Prize. But on the Templeton Foundation's page describing
the prize, the prize is described in these terms: “The
Prize celebrates no particular faith tradition or notion of God, but
rather the quest for progress in humanity’s efforts to comprehend
the many and diverse manifestations of the Divine.”
The page also refers to “the
John Templeton Foundation's mandate for breakthroughs in discovery
and outreach with direct or indirect relevance to 'Spiritual
Progress.' ”
What is very strange is that the Templeton Prize has sometimes been
given to those who seem to deny any spiritual realities or things such as manifestations of the Divine.
Let
us take the case of the most recent winner of the Templeton Prize,
physicist Marcelo Gleiser. Gleiser's opinions can be read in his
blog posts at this site. The 2019 posts are rather vague and bland about ideology.
But in a post from September 2018 entitled “Spiritual Materialism,”
Gleiser calls himself a materialist. After a section heading of
“Only Matter Exists,” we read the following:
“We
must, first and foremost, eliminate the connection between
spirituality and spirit, in particular, of spirit as a supernatural
manifestation. As I am sure Democritus, Lucretius, and Einstein would
agree, the starting point of the argument is that only
matter exists.
There is only the natural.”
This
is the doctrine of materialism, that only matter exists, and
Democritus and Lucretius are two of the five most famous atheists.
Materialism can be concisely described as atheism on steroids. An
atheist is someone who rejects the idea that there is some Supreme
Spirit. A materialist is someone who goes further, and rejects the
idea that there is any type of spirits or souls whatsoever, either in living
human beings or in some post-mortal or otherwordly realm.
Of
course, there is nothing the least bit spiritual about materialism.
When I search for a definition of spiritual, I get two definitions:
1."Relating
to or affecting the human spirit or soul as opposed to material or
physical things."
2. "Relating to religion or religious belief."
Materialists
do not believe in any such thing as spirits or souls, and reject all
religious belief. So Gleiser's “spiritual materialism” is a
self-contradictory oxymoron, like the concept of a square circle.
Materialism make no philosophical sense for an abundance of reasons,
such as the sudden unexplained origin of the universe, the extremely precise fine-tuning of the universe's laws and fundamenal constants, the impossibility of credibly explaining the origin of life through chemical effects, the apparent impossibility of explaining either the protein complexity or morphogenesis of a human through mere physical effects (without resorting to "DNA as body blueprint" myths), the very large body of evidence for psi and paranormal phenomena, and the utter inability of material effects to credibly explain basic human mental abilities and effects such as consciousness, abstract reasoning,
instantaneous memory recall and the 50-year retention of memories, the latter not being explicable by a brain in which synapse proteins have an average lifetime of only a
few weeks. The human mind and human mental experiences cannot be credibly imagined as something material.
Materialism
also makes not a bit of sense from a physics standpoint. As the study
of physics constantly involves you in important aspects of physical
reality that are not matter (such as pure energy and the laws of
physics), any competent physicist should be ashamed to call himself a
materialist. We are here partially because of an abundance of
physical laws that end up permitting habitable planets such as ours
and organisms such as ourselves. An example of such a law is the law
of the conservation of charge. When high energy particles collide, you
might think that protons (with 1836 times the mass of electrons)
would be created vastly less often than electrons. Instead
electrons and protons are created in exactly equal numbers. The
result is a planet like ours with an equal balance of positive
charges and negative charges. Were it not for such a law of nature,
we could not be here, there being various reasons why life would be
impossible if electrons were 1836 or even a hundred times more common
than protons. Laws such as this are not matter; the four fundamental
forces of nature (including gravitation) are not matter; and the
fields and the energy particles that fill the universe are also not
matter. So a physicist should know better than anyone the folly of
saying “only matter exists.”
In
another blog post entitled, “Does Life Have a Purpose?” Gleiser
gives us the answer that “there is no such thing,” and that “our
intelligence is not part of a grand plan.” These Gleiser
statements are inconsistent with what physicists know about
the extremely precise fine-tuning of the universe's fundamental
constants, such as the very precise equality (a difference of less
than .0000000000000000001) between the absolute value of the charge of every proton and the absolute value of the charge of every electron (an exact match necessary for our existence). Such precision seems to suggest a grand plan. But such
Gleiser statements are consistent with his previous statement of
materialism, that only matter exists. In these two blog posts Gleiser seems to reveal himself to be an opponent of the core notions of those who are spiritual and religious.
A similar very puzzling choice occurred when the Templeton Prize was awarded to cosmologist Martin Rees years ago. I rather doubt that you could ever find any spiritual-sounding thing Martin Rees had ever stated, although you could easily find some moral statements he had written. Rees has stated, “We are the nuclear waste of stellar fusion,” which concisely states his view that we are just random accidents. He has also stated, “What I would like best would be for scientists not even to use the word 'God.' " Note the words "like best," as if such a thing is his heart's fondest desire. That seems to suggest a very irreligious view.

we may ask: why were Gleiser and Rees each given the Templeton
Prize, a "spiritual progress" prize described on its web page as one given for those who
further “the quest for progress in humanity’s efforts to
comprehend the many and diverse manifestations of the Divine”? It's rather as if Donald Trump were to get some huge money prize from some Society for Progressive Liberalism, or if Bernie Sanders were to get some huge money prize from some League of Reagan Conservatives.
Postscript (September 2022): The Templeton Foundation's has no stable definition of what its prize is given for. The quotes given above were accurate quotes from the year 2020 versions of the Templeton Foundation's pages describing the prize. But if you now click on the links above, you will go to revised pages with a new description of what the Templeton Prize is given for. Now we are told that the prize merely "honors individuals whose exemplary achievements advance Sir John Templeton’s philanthropic vision: harnessing the power of the sciences to explore the deepest questions of the universe and humankind’s place and purpose within it." So now apparently the Templeton Prize is merely another prize for scientists. The claim that giving a prize to scientists does something to "advance Sir John Templeton’s philanthropic vision" is an inaccurate one. John Templeton tried to set up a foundation to promote progress in religion, not a foundation to give prize money to scientists. The 2022 winner of the Templeton Prize, Frank Wilczek, has not done much of anything to explore humankind's place and purpose within the universe. A look at his papers on Google Scholar seems to indicate that he has no great interest in such a thing, but seems a dozen time times more interested in matter and energy than in humans.

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:
- the problem of explaining how humans are able to have abstract ideas;
- 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;
- 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;
- 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;
- the problem of how humans are able to produce great works of creativity and imagination;
- the problem of how humans are able to be conscious at all;
- 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;
- the problem of how humans have such diverse skills and experiences as mathematical reasoning, moral insight, philosophical reasoning, and refined emotional and spiritual experiences;
- 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;
- 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."
"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.
