Rupert Sheldrake’s “Heretical” Caricatures of Scientists and Science

In Rupert Sheldrake’s book, The Rebirth of Nature: The Greening of Science and God, there’s a passage about science and scientists which encapsulates Sheldrake’s own serious problems with both. It’s also, it will be argued, full of caricatures and gross exaggerations.

Alfred Rupert Sheldrake (who was born in 1942) is a very controversial figure.

He’s an English author and parapsychology researcher. Sheldrake is now primarily known (at least in scientific circles) for his “conjecture” of morphic resonance, which has been strongly criticised by scientists and by many others. Indeed, it’s often been classed as mere pseudoscience.

Yet Sheldrake is indeed a scientist.

He’s worked as a biochemist at Cambridge University, been a Harvard scholar, a researcher at the Royal Society, and a plant physiologist.

Sheldrake has also done work on precognition, telepathy, and the psychic staring effect. Consequently, he’s been described as a “New Age” theorist.

Now for a few words on Rupert Sheldrake’s book The Rebirth of Nature.


The Rebirth of Nature is interesting. It’s very well written, easy to understand, and, oddly enough (at least to me), not in the least bit pretentious. (This is in marked contrast to other books written by people who’ve similar views to Sheldrake.) It’s also very interesting in terms of its neat little histories, as well as its informative capsule-form accounts of various aspects of science.

Where this book is controversial is in its philosophical additions. It’s also problematic because of its large use of bizarre analogies (see note 3), as well as its free and easy — often postmodern - interpretations of religion and history.

[Sheldrake relies on “postmodern theologians”, etc. for some of his views. See note 1.)

More broadly, it may be useful to place the passage focussed upon in this essay within the context of Sheldrake seeing himself as a scientific “heretic”.

To be fair to Sheldrake, that word was originally used (very critically) about Sheldrake by someone else. However, it’s safe to say that Sheldrake has now clearly and happily adopted this designation for himself. (See here.)

John Maddox

The word “heretic” was used by the theoretical chemist, physicist and science writer John Royden Maddox in response to Sheldrake’s book A New Science of Life, which was published in 1981. Maddox’s 1981 editorial (in Nature) is called ‘A book for burning?’.

Now clearly the word “heretic” and the title “A Book for burning?” are well over the top. That said, Maddox did conclude that the book should not be burned.

[Maddox’s piece also appears to have been part of a series called ‘A book for burning’. See more information in note 2.]

Yet I still have serious problems with Maddox’s rather intemperate and authoritarian remarks.

For example, Maddox later said (in 1994, some 13 years later) that he still thought that

“it is dangerous that people should be allowed by our liberal societies to put that kind of nonsense into currency”.

This is outrageous stuff.

It’s not the use of words like “nonsense”, “pseudoscience”, etc. that I have a problem with. (See some examples of Sheldrake’s bizarre statements in note 3.) It’s the highly-objectionable words “it’s dangerous that people should be allowed by our liberal societies to put that kind of nonsense into currency”.

No wonder Sheldrake has such a negative attitude toward science and scientists with people like John Maddox shouting at him. However, this is all that’ll be said on the Maddox-Sheldrake controversy here.


In any case, in this essay I shall break the aforementioned passage from Sheldrake down, and tackle each part separately.

But, firstly, it’s worth stating it in full:

“To this day, scientists pretend that they are rather like disembodied minds. Unlike other human activities, science is supposed to be uniquely objective. Scientific papers are conventionally written in an impersonal style, seemingly devoid of emotions. Conclusions are meant to follow from facts by a logical process of reasoning, such as that which might be followed by a computer, if machines with sufficient artificial intelligence could ever be constructed. Nobody is ever seen doing anything, methods are followed, phenomena observed, and measurements are made, preferably with instruments. Everything is reported in the passive voice. Even schoolchildren learn this style, and practise it in their laboratory notebooks: ‘a test tube was taken…’
“All research scientists know that this process is artificial; they are not disembodied minds, uninfluenced by emotion.”

Do Scientists Believe They Have Disembodied Minds?

Rupert Sheldrake — looking very disembodied.
“To this day, scientists pretend that they are rather like disembodied minds.”

No scientists I’ve ever read or come across has pretended that he/she is a disembodied mind. (Obviously, this is a partly anecdotal view.) So readers can guess that what Rupert Sheldrake must have meant is that this is the implicit (or subconscious) position of (all? most? many?) scientists. Alternatively, this supposed pretence is a consequence of what scientists do explicitly (or actually) believe and say…

Still, there’s still no direct (or literal) pretence from scientists that they’re “like disembodied minds”.

Many scientists (as it were) get around all this with the distinction they make between science itself and (flesh and blood) scientists. However, some critics of science and postmodern philosophers have argued that this distinction is a fake — largely because they see it as an idealisation.

Philosophers attempt a similar job with their own distinction between the context of discovery and the context of justification.

It can be suspected that Rupert Sheldrake will be aware of these two distinctions. However, it can also be assumed that he doesn’t really buy them — at least not unquestioningly.

In other words, is this simply Sheldrake’s interpretation of what scientists believe? Indeed, even if (most? many? some?) scientists do believe that they have a monopoly on what people call “the objective facts”, then that still wouldn’t entail a commitment to believing that their minds need to be disembodied in order to access those objective facts.

What’s more, if the minds of scientists were truly disembodied, then gaining access to data, facts, experimental results, etc. would be a very tricky business indeed.

Perhaps, then, it’s pure rhetoric (or poetry) to argue that scientists “pretend that they are disembodied minds”.

Sheldrake continued:

“All research scientists know that this process is artificial; they are not disembodied minds, uninfluenced by emotion.”

Some readers can partially agree with Sheldrake here. In other words, there is indeed a certain degree of artificiality involved in academic writings and in science generally.

And that’s a good thing… Or at least it is in specified cases.

Thus, it’s not that scientists “pretend”: it’s that this artificiality is productive and it makes sense. In other words, it just wouldn’t benefit anyone to read feelings and emotions displayed in papers, etc. Sure, it may benefit a psychoanalyst, psychological researcher, people like Sheldrake, or someone who just wants to wallow in other people’s feelings. However, what point would it serve in scientific papers?

Moreover, outside science, emotions and feelings are expressed all the time, and often in an extreme manner. This is certainly the case in the domains of religion, politics, art, etc.

Is that a good thing?

Indeed, even if the expression of one’s feelings and emotions is a good thing in politics, religion and art, would it (automatically) be a good thing in science too?

Sheldrake then tackled the very specific case of what he called “scientific papers”. He wrote:

“Scientific papers are conventionally written in an impersonal style, seemingly devoid of emotions. [] Everything is reported in the passive voice.”

[See the non-ironic article ‘Academic writing tips: How to use Active and Passive voice’.]

Isn’t this true of nearly all academic work?

Isn’t it the case that almost all academic papers and academic books are “written in an impersonal style, seemingly devoid of emotions”?

And isn’t that the case for many (or at least some) good reasons?

Would it be a fruitful or a good thing that “emotions” or feelings were fully displayed in scientific papers?

This may depend on how much emotion Sheldrake believes should be displayed by scientists. A lot of emotion? Just a bit? About as much as Sheldrake himself displays in these passages, and in the rest of his book?

Indeed, would it benefit anyone to parade and express their feelings in response to other people parading and expressing their own feelings?

What’s more, what, exactly, is the alternative to this “impersonal style”, and would it be a good thing to adopt it in scientific papers?

Sheldrake then had more to say on the scientific style:

“Even schoolchildren learn this style, and practise it in their laboratory notebooks: ‘a test tube was taken…’.”

So would Sheldrake prefer the following? -

I erotically placed the sample into a beatific test tube. This event in my life filled me with wonder. And, all the while, I simply knew that doing this would advance my own career, as well as change our deeply corrupted mechanistic society.

This isn’t to deny that there is such a thing as academese. Indeed, I myself have problems with it. (See my essay Why (Many) Analytic Philosophy Papers are Pretentious and Hard to Read’.) However, some readers may still wonder what Sheldrake would want to put in its place.

Perhaps Sheldrake doesn’t want to put anything in its place.

Perhaps what he says is purely descriptive. Indeed, to some degree at least, it is.

Sheldrake on Scientists’ Naive Philosophy of Science

“Conclusions are meant to follow from facts by a logical process of reasoning, such as that which might be followed by a computer, if machines with sufficient artificial intelligence could ever be constructed.”

This passage is Sheldrake’s caricature. It’s what he believes (all? most? many?) scientists take science to be.

It needn't be denied here that at least some defenders of science have put it in his way — or in similar ways. However, they too would be using caricatures. (Many of these positive — but naïve — caricatures of science don’t come from actual scientists.) However, I just don’t believe that most — or even many — scientists think in this simplistic way.

Technically, I doubt that many scientists would use a phrase like “follow from facts”. Perhaps they may say “follow from the data”, “follow from the evidence”, or even “follow from the experiments”. However, the word “fact” isn’t a scientific technical term. It’s more often used by philosophers or, more relevantly, laypeople. (There have been many definitions of “fact” which philosophers have offered us.)

What’s more, many scientists acknowledge that before any “logical process of reasoning”, the (to use Sheldrake’s other word again) “facts” too have (as it were) come about because of theory and prior processes of logical reasoning.

In any case, if scientists really believed that science were just another form of deductive logic (“such as that which might be followed by a computer, if machines with sufficient artificial intelligence could ever be constructed”), then what would be the point of the tests, falsifications, verifications, etc. of their theories? Indeed, what role would experiments play in science?

Again, if everything in science simply followed from the facts in a logical way, then science would be a purely deductive system.

Yet hardly any scientists have thought of science in these terms.

So is this simply Sheldrake’s caricature?

Here’s more from Sheldrake on the idea that scientists implicitly or explicitly see science as (some kind of) deductive system:

“Nobody is ever seen doing anything, methods are followed, phenomena observed, and measurements are made, preferably with instruments.”

Sure “methods are followed” in science. However, that’s methods in the plural. And the methods which are followed are often questioned, and even, at times, entirely rejected.

To be fair to Sheldrake, he did concede that “phenomena [are] observed”. So readers can suppose that in a purely deductive system phenomena and observation would play no role. Still, Sheldrake almost implies that “scientists” believe that phenomena are essentially the given (see ‘myth of the given’), and once they’re given, then the deductive process can begin. However, and as already stated, most scientists don’t believe that phenomena (or facts) are simply given. Not only that: they don’t see what follows as being a purely deductive process either.

As for Sheldrake’s words “measurements are made, preferably with instruments”.

It’s as if Sheldrake is implying that scientists believe that science has no role for theory. (This is, basically, a Baconian/17th century position on science.) This is astonishing because the word “theory” is used all the time in science, and not only in theoretical physics and theoretical biology — in all the sciences.

Again, this actually seems like a layperson’s view of science, not a scientist’s view of science.

And it certainly isn’t the view of science of Sheldrake’s pluralised “scientists”.

So since Sheldrake’s take on what scientists believe is such a caricature, then perhaps (again) he’s really talking about what laypeople believe about science. However, in the context of his strong criticisms of science and scientists generally, this can’t be the case.


Notes

(1) Rupert Sheldrake seems to have relied a fair amount on the American “postmodern theologian” David Ray Griffin. (Three of Griffin’s books appear in the bibliography.)

Griffin himself attempted to build a bridge between what he called modernity and postmodernity. He offered his readers — and others - “postmodern proposals” to solve the conflicts between religion and science. And, in 1983, Griffin established the Center for a Postmodern World and also became editor of the SUNY Series in Constructive Postmodern Philosophy.

More relevantly, just like Sheldrake, Griffin had many negative things to say about what he called “mechanistic science”. Indeed, Griffin’s book The Reenchantment of Science: Postmodern Proposals (1988) even has a title which is very similar to a couple of Sheldrake’s own books, including the 1990 publication focussed upon in this essay (i.e., The Rebirth of Nature).

(2) ‘A book for burning’ wasn’t even John Maddox’s own title! (See Martin Gardner’s ‘A book for burning’ in which he tackles Spontaneous Human Combustion, by Jenny Randles and Peter Hough.) What’s more, Maddox’s editorial on Sheldrake is only four paragraphs long.

(3) Quotes from Sheldrake’s The Rebirth of Nature:

“Everywhere we look in the realm of nature we find polarities, such as electrical and magnetic polarities. These can, if we like, be modelled in terms of gender [].”
“If the fields and energy of nature are aspects of the Word and Spirit of God [].”
[] even crystals, molecules and atoms are organisms.”
“Mythic, animistic and religious ways of thinking can no longer be kept at bay. Nothing less than a revolution is at hand.”
[T]he fields of modern physics play many of the same roles as souls in animistic, pre-mechanistic philosophies of nature.”

What Is a “Conscious Agent”? Donald Hoffman, Please Tell Me

 

(i) Introduction
(ii) Are Conscious Agents Primitives?
(iii) Planck-Length Conscious Agents
(iv) Reality and Conscious Agents

“If we really want to have an intelligent, and informative, and helpful discussion, we need to make sure that we’re using terms in a well-defined way that other people understand.”

Donald Hoffman [This passage is from a video called ‘Why clear definitions are key to intelligent discussions | Donald Hoffman’. See note 1 at the end of this essay.]

[] when you have limited math talents like me. [] That’s what led me to then go to a real mathematician [and fellow idealist] Chetan Prakash and pursue the theorems now in the case of the agent dynamics.”

Donald Hoffman [From a YouTube video called ‘Abstract Math of Conscious Agent Theory w/ Dr. Donald Hoffman’. See Chetan Prakash.]


Introduction

From one of Donald Hoffman’s papers.

Donald Hoffman’s notion of what he calls a “conscious agent” is central to to his entire idealist philosophy.

Hoffman tells his readers lots of things about conscious agents (which usually involves lots of numbers, symbols, graphs and mathematical terms). He also tells his readers what conscious agents can do. However, he doesn’t really tell them what conscious agents are.

I’ve written a few essays on Donald Hoffman. The reason I’ve done so is that although Hoffman is a best-selling writer (see The Case Against Reality), and is extensively interviewed and discussed (at least for a scientist) on YouTube, in newspaper articles, magazines, etc., he’s been virtually ignored by professional scientists and professional philosophers. [See note 2 at the end of this essay.]

In any case, after studying Hoffman’s work for a few years, I still didn’t really understand what a conscious agent is. More importantly, Hoffman never really says what a conscious agent is. He does other things instead, such as provide his readers and followers with lots of maths to explain what conscious agents do.

Even in a section called ‘Conscious Agents’ (which is part of his paper ‘The Origin of Time In Conscious Agents’), Hoffman never tells his readers what a conscious agent is. Instead, we have lots of diagrams, charts, numbers and symbols. We also read about “evolution”, “natural selection”, “Einstein”, “species-specific adaptation”, “physicalism”, “the mind-body problem”, “spacetime”, “Turing machines”, etc. In fact, everything under the sun seems to be discussed in Hoffman’s paper on conscious agents and time.

All that said, Hoffman does seem to say that a conscious agent is some kind of fundamental entity. In other words, a conscious agent is Hoffman’s philosophical equivalent of Leibniz’s monad, a particle, or something beyond — or at —the Planck length/s. Yet Hoffman also argues that he and other human persons are conscious agents too.

Of course, Hoffman might well have told his readers, fans and followers what a conscious agent is. And the fact that I haven’t personally grasped that may simply be a fact about my own personal cognitive deficiencies (i.e., dumbness).

This must mean that the American biologist Jerry Coyne is (to use his own word) “dense” too. Coyne similarly wrote:

“For the life of me I can’t figure out what the man is trying to say. [] it seems that what [Donald Hoffman is] saying should be clear. Yet what I read is either unclear, or, when it’s clear, seems wrong. [] It’s all a mess, and seems a bit like a gemisch of quantum woo, evolutionary misunderstandings, and postmodernism. If there’s a substantive and important point in the piece, I’ve been too dense to see it.”

Alternatively, Hoffman may not ever actually tell his readers and fans what a conscious agent is — at least not in simple terms. Instead, he may use mathematical and technical obfuscation to hide this fundamental flaw in his entire (seemingly mathematical) philosophy.

Oddly enough, one follower (or fan) of Hoffman does seem to understand exactly what a conscious agent is. The guy who understands Hoffman is an “entrepreneur, venture partner, inventor of the Quantum Backward Thinking” called Dr. Leon Eisen.

In an article called ‘How The Theory Of Conscious Agents Can Revolutionize Your Leadership’ (published in Forbes), Dr. Leon Eisen states the following:

[T]he concept of conscious agents provides an exciting framework for understanding how conscious leaders can shape their teams’ perceptions. The theory states that our perceptions of the world are not just a passive reflection of reality but are actively shaped by our beliefs, values, experiences and purposes. As leaders, we have the power to influence and shape others’ perceptions by creating a culture of diversity that supports and empowers them.”

Dr Leon Eisen continues:

[T]he theory of conscious agents suggests that our perceptions of the world are not fixed and predetermined but are actively shaped by the conscious agents’ network. By challenging the deterministic foundation of our world, conscious leaders can create a more dynamic and adaptable business environment that incorporates purpose rather than cause.”

Of course, I used the word “understand” ironically.

Yet it’s clear that Eisen believes that he understands “the concept of conscious agents”. The problem here is that Eisen doesn’t really tell us what a conscious agent is either. Perhaps more correctly, nothing in Eisen’s account distinguishes Hoffman’s term “conscious agent” from the terms “subject”, “person” and even “adult human being”. Indeed, Eisen’s account of Hoffman’s “theory” (or “concept”) of conscious agents is an embarrassing mixture of fluffy corporatese and philosophical positions which were held long before Donald Hoffman was even born.

Are Conscious Agents Primitives?

It may be the case that conscious agents are primitive, fundamental or even brute, and that would explain why Hoffman doesn’t tell us what they are… Except, again, that he says that he is a conscious agent, and that other human persons are too.

The case for primitiveness or fundamentality certainly applies to Gottfried Leibniz’s monads. And Hoffman has been strongly influenced by Leibniz’s work.

Hoffman obviously and strongly connects Leibniz’s monads to his own conscious agents.

Thus, we have these words from Hoffman:

[I]n the system of G.W. Leibniz who proposed that simple substances (‘monads’) are the ultimate constituents of the universe and that physics, as it was known back then, would result from the dynamics of a network of such monads.”

Hoffman expands on this in the following passage:

“Our posits for the notion of a conscious agent mirror G.W. Leibniz’s posits for his notion of a simple substance: ‘there is nothing besides perceptions and their changes to be found in the simple substance. Additionally, it is in these alone that all the internal activities of the simple substance can consist’.”

In very basic terms, then, Hoffman is simply substituting the word “monad” with his own words “conscious agent”.

So now take the word “primitive” as it’s used in the following passage:

“In Hoffman’s theory, conscious agents are the primitive constituents of reality. The objective world consists of conscious agents and their experiences. [] [H]umans are just one complex type of conscious agent.”

We aren’t really told what conscious agents are in that passage either. We are told that they are “the primitive constituents of reality”. And then we’re given an example of a “complex type of conscious agent” — a human conscious agent.

I could say that blairbles and catjumps are the “primitive constituents of reality”. However, most readers may still want to know what they are.

Say that quarks and/or fields are taken to be primitive (or fundamental) in physics. Physicists can, of course, tell us a hell of a lot about both.

So what about conscious agents?

It’s no use being told that “humans are just one complex type of conscious agent” if we don’t know what a conscious agent is in the first place. Similarly, being told that the “objective world consists of conscious agents and their experiences” isn’t of much help either if we aren’t told what conscious agents are.

What’s more, we aren’t really told (at least not in the passage above) why humans are a “complex type of conscious agent”, and what accounts for that complexity. (Hoffman’s complex “maths” doesn’t do so either.)

One interesting distinction in the passage above is the one made between conscious agents and “their experiences”. (This clashes with Hoffman’s earlier quotation of Leibniz saying “there is nothing besides perceptions and their changes”.) This tells us that conscious agents are over and above their experiences. That is, conscious agents are not equal to their experiences. (They’re not identical to their experiences.) And neither are conscious agents entirely constituted by their experiences.

All this, of course, raises the same question:

What is this conscious agent which has, or which instantiates, experiences?

As it stands, this account of Hoffman’s position is actually just a bunch of categorical statements or even mere stipulations. That said, Hoffman himself does go into detail. However, when he does, he still doesn’t tell us what a conscious agent is.

For example, in his paper ‘Conscious Realism and the Mind-Body Problem’, Hoffman explains that “a conscious agent is not necessarily a person”.

That’s fair enough.

It’s true that simply because Hoffman has said that he and other human persons are conscious agents, then that doesn’t also mean that all conscious agents must be human persons.

Hoffman continues:

“All persons are conscious agents, or heterarchies of conscious agents, but not all conscious agents are persons.”

That’s it.

At least Hoffman leaves it there in this passage, and indeed in the paper this comes from.

Planck-Length Conscious Agents

On the one hand, Hoffman argues that the category of conscious agents includes himself and other human persons. On the other hand (at least according to Maciej Sitko),

“Hoffman’s take is about conscious agents all the way down to the size of binary agents (Planck length/area sizes)”.

Sitko continues:

“The world is composed of conscious agents that compose bigger and bigger agents. It might even have place for a scientific take on God, who can be an uber-agent containing all subordinate agents at once.”

As for this fusion (or combination) of “bigger and bigger” conscious agents, Hoffman himself tells us (in his paper ‘The Origin of Time in Conscious Agents’) that

[i] happens that there are networks of conscious agents that have the computing power of universal Turing machines, and that any subset of a pseudograph of conscious agents is itself a single conscious agent”.

What does that mean?

In any case, is all this a display of Hoffman’s very own combination problem?

Thus, is Hoffman’s notion of a “fusions of consciousness” (as it were) additive in nature? In other words, is it simply that conscious agents can add (or sum) together? Alternatively, is adding different from fusing? (The similarity with panpsychism's original combination problem is obvious.)

More relevantly, can Hoffman use the same term (i.e., “conscious agent”) for something “the size of binary agent (Planck length/area sizes)” as he does for a conscious agent like Donald Hoffman himself — with his brain, legs, arms and so on? In other words, what do these Planck-length conscious agents share with a conscious agent like Donald Hoffman? In other words, what right has Hoffman to use the words “conscious”, “agent” and “conscious agent” about entities at the size of Planck lengths at all?

Perhaps one can guess here that Hoffman explains all this in terms of the (what he calls) “fusions” of Planck-length conscious agents. (See Hoffman’s paper ‘Fusions of Consciousness’.) So is it that Planck-length conscious agents fuse (or combine) together in order to create (or bring about) a Hoffman-sized conscious agent?

Added to these combination (or fusion) problems is Hoffman’s additional idea that Hoffman-sized conscious agents can also combine (or fuse) with other Hoffman-sized conscious agents…

But what on earth does all that mean?

What is the end result of all these fusions or combinations?

Is it just about the bringing forth of a “larger” conscious agent? Additionally, is it also about the (what Hoffman calls) “projections” of these larger conscious agents?

Some readers may still be completely in the dark here.

Hoffman rarely — if ever — explains any of this in scientific (physical) terms, even though he clearly sells his philosophy as being scientific. (He can’t explain it in physical terms because he’s an idealist.) Instead, he’s created his own jargon, which he embeds in (what seems to be) mathematical models. However, what is the point of such embedding if we’re never really told what these mathematical models are models of.

We get so much jargon and maths, but very little meat.

So what about reality itself?

Hoffman has had much to say about reality (such as in his book The Case Against Reality), largely from an evolutionary perspective (which shall be ignored here).

Reality and Conscious Agents

Hoffman tells us that

“reality is a vast interacting network of conscious agents, a social network like the Twitterverse”.

In the same YouTube interview, Hoffman also says that

“because reality is a bunch of conscious agents, and I’m a conscious agent, then I’m not divorced from reality”.

Hoffman uses the “is” of identity twice here — as in “reality is a vast interacting network of conscious agents” and “reality is a bunch of conscious agents”. In addition, earlier in this essay Hoffman was quoted as saying that “in the system of G.W. Leibniz [he] proposed that simple substances (‘monads’) are the ultimate constituents of the universe”. (There is an entire YouTube video called ‘Is Reality Made of Conscious Agents: Don Hoffman / Idealism’.)

Now, in this ontology, is reality actually constituted by (or “made of”) “a vast interacting network of conscious agents”? That is, is reality equal to — or identical with — this vast interacting network of conscious agents? Alternatively, is reality a product of, a result of, or (to use Hoffman’s word) a “projection” of such conscious agents?

Hoffman’s talk of “icons” and “projections” (along with his commitment to idealism itself) seems to suggest that reality can’t actually be a vast interacting network of conscious agents. The idealist message is surely that reality is somehow the product, result, or projection of a vast network of conscious agents.

Yet these two positions are very different.

So which one is it?

The distinction between a reality that is actually constituted by a vast number of conscious agents, and a reality that is projected by conscious agents, has just been mentioned.

One commentator (seemingly a fan too) of Hoffman believes that conscious agents simply “simulate consciousness”. (I’m not even sure what that means.) In his own words:

“Hoffman’s agents are a way to simulate consciousness, the conscious agent has rules of reaction when it meets another [conscious] agent.”

Isn’t that a very deflationary account of Hoffman’s philosophy?

In other words, this isn’t about ontological entities: it’s about ways of simulating consciousness. In this account at least, conscious agents are simply simulations of consciousness.

Yet doesn’t Hoffman believe that conscious agents are real ontological entities, not simulations of… anything? Indeed, aren’t these conscious agents themselves supposed to be responsible for all simulations, “icons”, objects, etc? In other words, aren’t physical objects, spacetime, brains, neurons, etc. merely the icons of conscious agents?

Thus, in Hoffman’s (idealist) philosophy, conscious agents aren’t the simulations of consciousness: they are the very ground and source of reality.


Notes

Some extracts from a single paper by Donald Hoffman — ‘Fusions of Consciousness’.

(1) I’m guessing that what Donald Hoffman means by “using terms in a well-defined way” is using an often impenetrable prose, which incudes lots and lots of mathematical terms, scientific jargon, graphs, numbers and symbols.

I, for one, will happily admit that most of the time I don’t “understand” what Hoffman is saying (just like Coyne). The odd thing is that, in the many interviews of Hoffman I’ve seen (there are literally dozens on YouTube — see here), those who interview him don’t seem to understand him either. Instead, they’re either starstruck by his jargon (many interviewers look like they’re in awe of the man), or they ask him to elaborate upon (i.e., they don’t question or criticise) what he’s just said, which he does with yet more jargon.

Very rarely — almost never — do his interviewers criticise or even question what Hoffman states with so much confidence. (The philosophers Philip Goff and Keith Frankish come close to being critical of Hoffman’s ideas — or his jargon — in a YouTube video called ‘What is Reality?’.)

Bernardo Kastrup

(2) This isn’t the case when it comes to Donald Hoffman’s work which falls purely within the domain of cognitive science. So it can safely be assumed that other professional scientists have indeed read and tackled Hoffman’s (purely) cognitive-science work.

Incidentally, Donald Hoffman’s fellow spiritual idealist, Bernardo Kastrup, takes this situation of professional scientists and professional philosophers almost completely ignoring his work as proof that he’s onto something profound and deep. In that sense, then, Kastrup clearly sees himself as a scientific and philosophical “heretic”, just as the English author and parapsychology researcher Rupert Sheldrake also does. (See Sheldrake the heretic here.) Relevantly, Kastrup classes nearly all scientists and philosophers (i.e., outside his spiritual idealism) as “materialists”. Thus, as a spiritual idealist, Kastrup can’t help but be an heroic heretic.

In his post ‘Reason or covetousness? On academic philosophy’, Kastrup also conflates professional scientists and professional philosophers taking his work seriously with the fact that he has indeed “engaged” with some professionals, and also been “invited to debate well-known philosophers”. In his own words:

[T]he fact that well-known academic philosophers — such as David Chalmers — have cited my work in print, or that others — such as Philip Goff — have gone out of their way to engage me multiple times in public, or that yet other academics — such as Keith Frankish and Michael Graziano — have had heated exchanges with me also in print, or that I’ve been invited to debate well-known philosophers and public intellectuals.”

All sorts of irrelevant people are cited in print. (Has Kastrup’s idealist philosophy ever been the main or sole subject of these citations in print?) In addition, Kastrup has a cult following. Thus, those people who arrange and produce popular-science and popular-philosophy debates are highly likely to invite Kastrup, who offers the general public a spiritual, sexy and titillating philosophy. And that must surely at least partly explain why some of the names Kastrup mentions have felt the need to “engage” with him. In their papers and books, on the other hand, they almost completely ignore him. (I would like to see how David Chalmers cites his work.) Of course, it’s possible that some of the people Kastrup names do indeed rate him. However, I’d bet money that they don’t.
