The Politics, Spirituality and Sexy Craziness of Panpsychism: Rudy Rucker and Philip Goff

Not all brands of panpsychism can be tied to spirituality, religion and/or politics. However, some (perhaps many) brands can be. This issue is complicated by those panpsychists who, in one breath, play down these connections; yet, in the very next breath, emphasise them. This essay, however, isn’t a critique of religion, spirituality or the politics of panpsychists. It’s simply an attempt to demonstrate these clear — indeed obvious — connections.

Philip Goff and Rudy Rucker
“Each object has a mind. Stars, hills, chairs, rocks, scraps of paper, flakes of skin, molecules — each of them possesses the same inner glow as a human, each of them has singular inner experiences and sensations.”

— Rudy Rucker

[See source here.]

“There are superficial cultural associations between panpsychism and spiritual stuff, but most of the people defending it are atheists [].”

— Philip Goff

[See source here.]

[Personally, I only know of a handful — or even less — of panpsychists who’ve used the word “atheist” to describe themselves. It also has to be remembered that many of those who class themselves as “spiritual” also frequently state that they don’t believe in the “traditional God”. Philip Goff himself makes much of this distinction.]

[Note: The word “craziness” — in the title — is borrowed from the panpsychist Philip Goff. He wrote an article called ‘Panpsychism Is Crazy, but It’s Also Most Probably True’, in which he compares panpsychism to Albert Einstein’s (supposedly) equally “crazy” (at least as seen at the time of its creation) Special Theory of Relativity. The very idea of a metaphysical thesis being “probably true” — as well as the comparisons with Einstein’s Relativity — won’t be discussed in the following essay.]

Introduction

It’s worth noting straight away that this essay only features two panpsychists who tie panpsychism to spiritual and political issues and positions. There are, of course, many others. For example, there are over 15 pages of search results (on Google) which contain numerous links to papers, articles and books which explicitly tie panpsychism to religion and spirituality (if in various ways). Hardly a single one of these links takes you to any critic of panpsychism attempting to (well) disingenuously connect panpsychism to spiritualism and religion. (That serious charge can, of course, be aimed at this essay.)

So readers can find Rupert Sheldrake tying panpsychism to what he himself calls “spirituality” (see here). A paper called ‘Panpsychism and Spiritual Flourishing’. Articles which tie panpsychism to “eastern mystics” (see here) and historical Native Americans (see here). Another article called ‘Why a Panpsychist Should Adopt Theism: God, Galileo, and Goff’. A book called Panpsychism and the Religious Attitude. Lots of pieces on “spiritual science”, which often mention panpsychism (see here). Finally, panpsychism has even morphed into an explicit spiritual position called panspiritism (see this article).

All that said, it’s not being argued here that all panpsychisms (i.e., in the plural) are, well, crazy or wacky. Some (though very few) panpsychists offer metaphysical theses which they argue for, and which can then be tackled by people who aren’t themselves panpsychists — even if, ultimately, they reject them.

Nonetheless, a philosopher like Philip Goff started off as simply offering technical papers and arguments (as expressed in academese in philosophy journals), but now he too is heading off in a crazy and/or wacky direction. And he’s doing so — at least partly — for the very same reasons as Rudy Rucker: politics, spirituality and ethics.

But, firstly, let’s concentrate on Rudy Rucker

Rudy Rucker

A young Rudy Rucker.

In his short essay, ‘Mind is a universally distributed quality’ (which can be found in the book What is Your Dangerous Idea?), Rudy Rucker (1946-) states that “[e]ach object has a mind”. He believes that “[s]tars, hills, chairs, rocks, scraps of paper, flakes of skin, molecules” all have minds.

Rucker isn’t simply arguing that all these objects have “experiences” or instantiate what some philosophers call “phenomenal properties”. And he certainly isn’t arguing that they only instantiate (as some other philosophers call it) “proto-experience”.

All that said, perhaps Rudy Rucker’s own panpsychism — particularly — is a bad target because I have a very strong feeling that he knows that his ideas are crazy-wacky and that his crazy-wackiness is part of the point, and, indeed, part of the appeal. After all, Rucker describes himself as a “cyberpunk” and he does seem to cultivate a certain image which appeals to New Agers, hippies, tribal environmentalists, etc.

[I’m not sure how cyberpunk and its “dystopian societies” square with Rucker’s panpsychist environmental ethics. However, I’m not an expert on cyberpunks.]

So Rucker’s crazy-wacky beliefs are tailor-made for a tiny niche of society. His books also sell very well (see here). And, as almost everyone knows, there’s nearly always a guaranteed (if sometimes small) market for sexy, titillating and crazy-wacky stuff.

All this means that perhaps many (or even most) of Rucker’s claims aren’t meant to be taken literally. Perhaps they’re meant to be taken poetically, politically or even spiritually.

It’s not a surprise, then, that Rucker never supplies any arguments for his panpsychism (there is a ‘nine-step formal proof of panpsychism’): he simply makes categorical (often oracular) statements. (He once strung them together and called them a “proof”.) And that ties in with all of what’s just been said. After all, arguments, data and facts may unweave Rucker’s rainbow or unspool his craziness-wackiness.

Indeed don’t we have the phrase “there are many ways of knowing” to deal with here? So perhaps Rucker’s very own way of knowing is different to my own way of knowing. It may also be different to the ways of knowing of most readers of this essay. That said, it’s of course the case that some people will be keen to point out (if not in these precise words) that one person’s crazy-wacky position is another person’s truth.

It must also be stated here that Rucker doesn’t seem to do — at least some of — his fellow panpsychists any favours. Or, at the very least, he doesn’t do the more philosophically rigorous and less flamboyant panpsychists any favours. (There aren’t many panpsychists who fit this description.)

In my view, then, spirituality, sexy philosophy and politics constitute the primary appeal of panpsychism when it comes to at least some (or even many) panpsychists and their followers. The hard analytical or philosophical work — which only exists in tiny academic niches — may well only arrive (as it were) after that fact.

The Spirituality and Politics of Rucker’s Panpsychism

It seems that radical environmentalism (perhaps alongside ecocentrism) and politics may be driving Rudy Rucker’s panpsychism. And now that seems to be the case with Philip Goff too. (See the last section.)

Both Rucker and Goff believe that upholding panpsychism will help the environment, our relationship with nature and the political state of society and the world generally.

Rucker himself is explicit about this when he wrote:

“If the rocks on my property have minds, I feel more respect for them in their natural state. If I feel myself among friends in the universe.”

As far as I know, Goff hasn’t delved into the afterlife yet. Rudy Rucker has.

Rucker offers us a spiritual, psychological and emotional take (actually, a conditional) on the afterlife when he stated the following:

“If my body will have a mind even after I’m dead, then death matters less to me.”

If Rucker’s previous speculations were true, then his position on his “mind” after his own death would also be true; or at least it could possibly be true. Thus, all this depends on the Rucker’s conjectures on panpsychism being true. (As stated in the opening square-bracketed note: metaphysical theories aren’t ideal candidates for truth.)

Yet Rucker’s panpsychist environmentalism and its lack of truth, fact or data may not matter to him. Thus, this is a reactive reply to Rucker’s general stance:

i) If Rudy Rucker’s panpsychism is all about his own emotional well-being (as well as about having a “positive attitude” to one’s environment),
ii) then it may not matter if panpsychism is actually true.
(“The point is to change the world, not interpret it.”)

What seems to matter to Rucker are the personal and even collective results of believing — or simply advocating — panpsychism as a philosophical and political position.

So here’s another conditional to get that point across:

i) If the political, social and/or ethical consequences of believing in panpsychism are deemed to be positive,
ii) then perhaps the truth of panpsychism doesn’t matter.

Something similar to this ethical and pragmatic stance on truth has often been noted by philosophers and other commentators when it comes to religion. For example, many philosophers (such as the American philosopher William James) have talked about the “efficacy of religion”. (Sam Harris now talks about the efficacy of spirituality.) This has also been seen to be the stance of the “late Wittgenstein”; at least on certain readings. (Yet the man himself hardly wrote a word on the issue.)

Yet this fast-and-loose attitude to truth, fact and data would surely create a philosophical, scientific and ethical free-for-all if everyone adopted it. (Who knows, perhaps there are — relativist? — arguments which state that this would be a good thing too.) After all, I personally could believe that Rudy Rucker is a rock in order to bring it about that no one will take his views seriously. I could also believe that the Welsh are crabs in order to bring forward all sorts of negative political policies against Welsh people.

So why give Rudy Rucker free rein, but not other people with similarly absurd or extreme views? Some people may do so simply because they like — or empathise with — Rucker’s panpsychist philosophy. But is that a good enough reason? Some other people may also like my view that Rucker is a rock or someone else’s view that “alien lizards rule the world”.

In any case, let's move on to Philip Goff, who’s far less crazy-wacky than Rudy Rucker. He is, after all, a tenured professor who specialises in analytic philosophy.

Part Two: Philip Goff

“Other[s] will identify as ‘spiritual but not religious’. The purpose of this article is simply to point out that there is a third option that many are not aware of, and that some may find attractive: religion without belief.”

— Philip Goff (See source here.)

“I’m exploring the position that there is some kind of teleology or goal-based activity at the fundamental level of the universe [] Like isn’t the universe conscious itself?”

— Philip Goff (See source here.)

Professor Philip Goff uses the experiments and research on plants (carried out by the ecologists Professor Monica Gagliano and Professor Suzanne Simard) to advance his panpsychism. That is, he interprets that research and the experiments in various political and philosophical ways.

Monica Gagliano

It can provisionally be accepted, then, that the experiments of Monica Gagliano and Suzanne Simard are scientifically kosher. And their papers, too, may well abound with mathematical equations and an infinity of footnotes and references. However, Goff’s political and philosophical interpretations of these experiments are what matters here.

That said, both of Monica Gagliano and Suzanne Simard themselves do foist philosophical and political baggage onto their own experiments and research. That philosophical and political baggage goes way beyond the actual science itself.

Indeed all this is a very good example of the common phenomenon of scientists — as well as philosophers and political activists — using scientific data or experiments as ammunition to advance their own political and/or spiritual beliefs, causes and goals.

Philip Goff’s Anthropomorphism

Philip Goff offers us some clear examples of anthropomorphism, which he uses to back up his prior panpsychism.

For example, Goff uses the words “associate”, “meaningless”, “preferential treatment”, “for their young”, “mother”, “kin”, “prejudice”, “reciprocal support”, “passing along” “egalitarian redistribution” and “dinnertime” when he refers to plants and their behaviour.

[The word “behaviour” is tricky when used in this context. For a start, the way that this word is sometimes used about plants — i.e., mainly by those who want to get a larger ethical, political or environmental point across — can also be used, with almost no change, about smoke alarms, light sensors and even wind turbines. However, all that can’t be tackled here.]

Perhaps the most extreme example of all is Goff’s use of the word “wisdom”. He uses that word when he says that “mother trees [] pass on their wisdom to the next generation”.

Now this is a professional analytic philosopher using the word “wisdom” about trees without even hinting at it being a metaphor or a poeticism… But that’s because he’s not using the word “wisdom” metaphorically or poetically.

Now it must be said that it’s of course the case that anthropomorphic words and phrases about plants or trees can be — and often are — used poetically and metaphorically, as well as to enable understanding. And, in that simple sense, such uses aren’t anthropomorphic in a literal sense at all. So this means that the least a philosopher or scientist can do is make it clear to his audience that he’s using such words (or phrases) in a poetic or metaphorical way. That said, in Goff’s case and as already said, it’s clear that he’s not using these word and phrases metaphorically, poetically or to enable understanding: he’s using them literally.

So take this passage as an example of this:

[W]e now know that plants communicate, learn and remember. I can see no reason other than anthropic prejudice not to ascribe to them a conscious life of their own.”

It’s ironic that Goff mentions “anthropic prejudice” when he himself is clearly indulging in gross forms of anthropomorphism. (Many scientists, philosophers and laypersons have a problem with anthropomorphism even when it comes to animals, never mind plants.)

Readers may now wonder why anthropomorphism is seen to be somehow better than what Goff calls “anthropic prejudice” (i.e., anthropocentrism). Yet don’t both positions share the same (as it were) ánthrōpos toward plants? Thus, aren’t both positions equally suspect?

Of course Goff doesn’t believe he’s being anthropomorphic at all.

Goff uses anthropomorphic ways of speaking when his examples can even be made to work against his own political take on plants.

And that highlights a problem here.

As noted, Goff does indeed refer to scientific research on plants.

However, exactly the same data, evidence or experiment about — or on — trees and other plants (as well as animals) can be used as ammunition to advance just about any political position. (See underdetermination of theory by data/evidence.) Indeed, historically, this has often been the case. (Think about how some 19th-century Darwinists and 20th-century fascists relied on the animal world to advance their politics.) More specifically, Goff’s talk of “quid pro quo relationship[s]” in the plant world could be used to advance political positions which are diametrically opposed to his own.

Finally, on the words “wisdom”, “egalitarian”, etc. as used by Goff.

The simple argument here is that Goff is using these terms in ways that are massively at odds with how they’re used by laypersons when they refer to human individuals, institutions or societies. That is, he’s using them in his own panpsychist and political way. What’s more, such terms pick out behaviours which are displayed by every member of a plant species — at least in a given environment.

Yet that simply isn’t the case with human beings.

The word “wisdom”, for example, is always used in a relative or contextual way. That is, it’s rarely used to refer to every single human being in all circumstances dating back tens of thousands of years (as must be true of most plants). That is, person, institution or society x is (or was) wise in comparison with other persons, institutions or societies who or which were unwise.

As for Goff’s word “egalitarian”: if every plant of a given species is egalitarian, then no plant of that species is egalitarian. Like wisdom, a tree can only be egalitarian if there’s the possibility that this tree (or the entire species it belongs to) can choose not to be egalitarian. Again: the word “egalitarian” implies that an individual, institution or society chooses to be egalitarian. In other words, the word “egalitarian” has moral or normative content and also involves various degrees of choice. That isn’t the case with the plant species Goff artfully selects. According to Goff (though he doesn’t explicitly state this), every plant of that species — and perhaps all plants! — is wise and egalitarian.

The same is true of Goff’s use of the words “prejudice” and “reciprocal support” when he refers to plants.

Do these plants have the choice to actually embrace prejudice instead?

Do such plants ever go against the reciprocal support Goff highlights?

And say that there are indeed some exceptions (which is doubtful — unless in cases of genetic and/or environmental anomalies) displayed by the plants of a given species — would they be morally flawed to display prejudice or reject reciprocal support?

So what’s the point of using these anthropomorphic words at all?

Such words have almost zero connection to how they’re used by laypersons — and probably even by Goff himself when he uses them in all other (i.e., non-panpsychist and non-political) contexts.

So that point must be political, spiritual or ethical — probably all three. What’s more, it can be argued that, when it comes to panpsychists like Rudy Rucker and Philip Goff, it really doesn’t matter if their claims are true (or if the terms they use are conceptually confused or simply deceitful) because they believe that embracing this way of looking at plants — and much else besides — is a means to change the world in a better political direction.

Finally, these brands of panpsychism are obviously not science. And perhaps most of them aren’t even philosophy either. Instead, they’re a type of politics and/or ethics which simply uses the findings of both science and philosophy to help bring about certain very specific social and political ends.

The Fact that Philosophy Isn’t Physics Annoys Some Popular Physicists

Some best-selling physicists really dislike philosophy and see it as a complete waste of time. Is this largely down to the very-simple fact that philosophy isn’t… well, physics?

(i) Introduction 
(ii) Philosophers Aren’t Physicists 
(iii) Stephen Hawking 
(iv) Lawrence Krauss and Sabine Hossenfelder 
(v) Some Physicists Have Been Right About Philosophy 
(vi) History

Some physicists (especially the ones who write best-selling books) have a big problem with philosophy. That problem is that they don’t like the fact that philosophy isn’t physics.

Of course they never put it quite so simply or honestly.

And, yes, such physicists have also given reasons for their anti-philosophy stances. Indeed a handful of the reasons they’ve given are subtle. However, most are crude and ignorant…

Yet it’s still essentially all down to philosophy not being physics.

The claims above may themselves seem as simplistic as the anti-philosophy positions of the aforementioned physicists. However, if you read the actual words of these physicists on this issue, then you’ll quickly note the lack of names of any actual philosophers or any details about what they argue.

The anti-philosophy physicists’ other big problem (which, of course, follows from their main big problem) is that philosophers aren’t physicists.

Philosophers Aren’t Physicists

One can guess (i.e., from the overall context) that the claims of anti-philosophy physicists basically amount to the fact that (most? all?) philosophers don’t understand the mathematics of physics and all the precise technical details involved in physical theories.

To put it more simply. Anti-philosophy physicists are basically saying that philosophers don’t know as much about physics as they do.

Of course no single physicist knows all the maths and all the technical details of physics either. Indeed most physicists have extremely narrow specialisms.

In addition, if philosophers knew as much about physics as physicists do, then they’d probably actually be physicists.

So it can be argued that such anti-philosophy physicists are replicating sociologist Steve Fuller’s own position against… physicists and biologists. (Specifically, against Murray Gell-Mann, Roger Penrose, Steven Jay Gould, etc.)

Steve Fuller’s basic problem (at least as I see it) is that physicists and biologists aren’t as emersed in sociology (or the social sciences generally) as he is.

Fuller wrote the following:

[T]o a sociologist, it will be apparent that many of the ‘deep puzzles’ that these scientists brood over could be solved, or at least dissipated, by a dose of social science [].”

So that can be rewritten in this way:

To a physicist, it will be apparent that many of the ‘deep puzzles’ that these philosophers brood over could be solved, or at least dissipated, by a dose of physics and science generally.

Indeed some physicists have said precisely that!

Fuller also stated this:

[T]he most disturbing feature of these interviews is that despite their interdisciplinary pretensions, none of the scientists ever feels the need to refer to theories or findings of the social sciences (except for a few derogatory remarks about economists). When [Steven Jay] Gould wants to flaunt his well-roundedness, he quotes Horace and Shakespeare, not Marx and Weber [].”

This can also be rewritten as follows:

The most disturbing feature of philosophers is that none of them ever feels the need to refer to the theories or findings of physics (except for a few derogatory remarks about [this is my addition] the lack of philosophical sophistication of physicists).

So Fuller himself is (if implicitly) asking his readers why biologists and physicists aren’t as immersed in sociology as he is. And anti-philosophy physicists are (more explicitly) asking their readers why philosophers aren’t as immersed in physics as they are.

In terms of Steve Fuller’s stance.

If physicists were as immersed in sociology as Fuller himself is, then they’d basically be sociologists.

In more detail.

Fuller mentioned various artfully-selected theories which his targeted biologists and physicists didn’t themselves mention or didn’t know anything about. And then Fuller went on to simply assume ignorance on the part of his targeted scientists for not knowing — or simply mentioning — these things…

So doesn’t that sound familiar?

It can now be said that there’ll be many other (relevant) things which these biologists and physicists know (or knew), and which Fuller himself doesn’t know. So perhaps such scientists show now repay the compliment and arbitrarily namedrop the theories and ideas which Fuller himself doesn’t know.

And that’s what anti-philosophy physicists sometimes do when criticising philosophy. (“You comment on physics, yet you haven’t mastered differential geometry, multilinear algebra, manifold theory and functional analysis!”)

To change tack a little.

A YouTube video called ‘Scientists vs Philosophers’ opens up with the host (a Steve Paulson) asking this question:

“Why is it that so many physicists are bashing philosophers nowadays?”

So now let’s single out the well-known case of Stephen Hawking.

Stephen Hawking

Stephen Hawking one stated that “philosophers haven’t kept up with physics”. Indeed (in his book The Grand Design) Hawking went into more detail in the following passage:

“Traditionally these are questions for philosophy, but philosophy is dead. Philosophy has not kept up with modern developments in science, particularly physics. Scientists have become the bearers of the torch of discovery in our quest for knowledge.”

Stephen Hawking is actually both a bad and an ironic example of an anti-philosopher. That’s for the simple reason that what he said about philosophy is very naive. That’s the bad part. More ironically, Hawking offered the world his very own philosophical position on physics, which he called model-dependent realism. Indeed Hawking even borrowed a technical term from philosophy — “realism”.

(“Realism” isn’t a term of — or in — any branch of physics I know. However, it is sometimes used in the interpretations of quantum mechanics.)

Now how bizarre is all that?

So here’s a taster of Hawking’s very own philosophy:

“There is no picture- or theory-independent concept of reality. Instead we will adopt a view that we will call model-dependent realism: the idea that a physical theory or world picture is a model (generally of a mathematical nature) and a set of rules that connect the elements of the model to observations. This provides a framework with which to interpret modern science.”

Sure, it might have been the case that Hawking didn’t see his model-dependent realism as a philosophical position. He might have seen it as, say, a simple description of “the facts” or a description of the methodologies of physics. Yet that too would have been very naïve.

In addition, since Hawking classed himself as “a positivist” on more than one occasion, then his complete rejection of philosophy was even more ridiculous and naïve that so far characterised.

Many of the words above may also apply to Lawrence Krauss.

Lawrence Krauss and Sabine Hossenfelder

In an interview with Ross Anderson, American theoretical physicist and cosmologist Lawrence Krauss (1954-) said:

[T]he worst part of philosophy is the philosophy of science; the only people, as far as I can tell, that read work by philosophers of science are other philosophers of science.”

Despite that, Marcus Munafo (a professor of biological psychology) and George Davey Smith (the director of the MRC Integrative Epidemiology Unit at the University of Bristol) have written the following words:

“Richard Feynman once claimed that the ‘philosophy of science is as useful to scientists as ornithology is to birds.’ We disagree.”

Sure, that’s an example of only two scientists mentioning the philosophy of science. That said, perhaps I don’t need any examples for my general argument here.

In any case, perhaps physicists would pick up on the fact that these two pro-philosophy scientists aren’t physicists. (Biological psychology isn’t physics and epidemiology isn’t physics either.) So are such anti-philosophy physicists Sheldon Cooper-type characters in that they too have very little respect for any discipline — other than mathematics — that isn’t theoretical physics? (Shelden Cooper is — or was — a young and “eccentric” theoretical physicist in the American sitcom The Big Bang Theory.)

This state of affairs was also perfectly captured by the German theoretical physicist and YouTube presenter Sabine Hossenfelder.

Hossenfelder wrote an article (called ‘Electrons Don’t Think’) on the philosophical position of panpsychism. In that article she doesn’t quote a single panpsychist, tackle a single argument in support of panpsychism or even paraphrase a single panpsychist’s words. (See my ‘Sabine Hossenfelder Doesn’t Think… About Panpsychism’.)

Hossenfelder may argue that she hasn’t the time to do any research on panpsychism or on philosophy generally. Yet she had the time to write this article on panpsychism.

Some commentators and readers may also argue that it’s only the philosophy of science that physicists like Krauss and Hossenfelder have a problem with. Yet that obviously doesn’t apply to Hossenfelder’s words on panpsychism.

So if Krauss and Hossenfelder already believe that “philosophy hasn’t kept up with science” (and therefore that philosophy has nothing to offer science/physics), then no wonder they have such a naïve view of philosophy. That is, Krauss and Hossenfelder are taking part in some kind of self-fulfilling prophecy here:

i) Because Kraus and Hossenfelder already believe that philosophy has nothing to offer science,
they never read philosophy.
ii) And because they never read philosophy,
they consequently believe that philosophy has nothing to offer science.

That said, it can be assumed that both Kraus and Hossenfelder would argue the following (though perhaps they wouldn’t even bother doing so):

Because we’ve already read philosophy, then that’s why we believe that philosophy has nothing to offer science.

There are many reasons to strongly believe that isn’t the case. (Some of those reasons are mentioned in this essay.)

Thus, all Krauss and Hossenfelder are really showing us here is their own ignorance of philosophy. They aren’t showing us that (all? some?) philosophers are ignorant of physics and science generally.

To sum up.

One gets the impression (which can be backed up with fact) that people like Krauss and Hossenfelder simply haven’t read much — or even any — contemporary philosophy. What’s more, at various places and at various times (if in roundabout ways), they’ve freely admitted this! After all, why should Krauss, Hossenfelder and other anti-philosophy physicists read philosophy if they already believe (as just argued) it’s a waste of time?

Some Physicists Have Been Right

Not to be entirely one-sided and biased, it’s worth stating that some of the criticisms of philosophy from physicists have been worthwhile, apt, and… philosophical.

Indeed many philosophers have themselves claimed that philosophy is dead (if not in those precise words).

Why “dead”?

Again, it’s because some (i.e., not all!) philosophers haven’t kept up with physics and science generally. (As stated, however, it depends how the words “kept up with science” are read.)

Ontic structural realists are a clear example of this. (They too don’t have every philosopher under the sun in mind.)

And a few other philosophers (such as Daniel Dennett — see here) are also critical of philosophers for many of the same reasons cited by anti-philosophy physicists.

On a related theme.

One can understand how certain physicists are irked by philosophers if the American philosopher of physics, David Z. Albert, was correct when he stated (in the video cited above) the following:

“There have been instances of philosophers telling physicists that they’re not doing their jobs properly.”

That may explain why these anti-philosophy physicists get so pissed off by philosophers. At least David Albert’s words may offer us a partial explanation of that.

So now take on board the following passage (which is in tune with what Albert just said) from the philosopher of science, Wesley Salmon. He wrote:

“While the philosopher of science may be basically concerned with abstract logical relations, he can hardly afford to ignore the actual methods that scientists have found acceptable. If a philosopher expounds a theory of the logical structure of science according to which almost all of modern physical science is methodologically unsound, it would be far more reasonable to conclude that the philosophical reasoning had gone astray than to suppose that modern science is logically misconceived.”

The host of the previously-cited video debate also tells us that physicists claim that “philosophers don’t add any knowledge to the world”. That’s very ironic because it was philosophers themselves (e.g., the logical positivists and Ludwig Wittgenstein — see here) who first made precisely that point in the 1920s and 1930s.

Yet this also means that in order for physicists to claim that philosophy doesn’t add any knowledge to the world, then surely they must do some philosophising themselves. Among other things, anti-philosophy physicists must do the following:

1) Explain what they mean by the word “knowledge”.
2) Tell us why philosophical claims aren’t examples of knowledge.
3) Tell us why scientific knowledge is actually the only kind of knowledge. 
4) And finally tell us why scientific knowledge (or science itself) must have such a preeminent status in society.

None of the positive or negative answers to those questions will be scientific in nature. And they certainly won’t be part of physics!

One would hope, then, that anti-philosophy physicists won’t argue that such questions shouldn’t even be asked.

However, if any physicists did argue (or simply believe) that these questions are a waste of time (i.e., precisely because they’re philosophical), then that extreme position would itself need to be philosophically defended and backed up. And if such scientists didn’t defend it (or if they believe that they aren’t required to defend it), then that stance will — again — need a philosophical defence.

Ironically, it can just as easily be said that much physics is dead because physicists haven’t kept up with philosophy.

History

Historically, it was the case that nearly all scientific advances had their roots in philosophical ideas and theories. And as a consequence of that, it can now be said that the revolutionaries of physics have always been both philosophically inclined and aware of much philosophy.

So although there have indeed been critical remarks about philosophy from physicists, there haven’t been as many as some readers may think.

Albert Einstein, to take just one example, owed a strong debt to Ernst Mach, Immanuel Kant and Baruch Spinoza (as well as others). Even Isaac Newton was well-schooled in philosophy and his own physics was called (as is often pointed out) “natural philosophy”.

In terms of contemporary — as well as somewhat less recent — philosophical physicists and physicists who don’t diss philosophy (though they do, of course, diss particular philosophical positions or theories), we have Lee Smolin, Roger Penrose, Carlo Rovelli, Murray Gell-Mann, Sean Carroll, Brian Greene, Julian Barbour, Paul Davies, Freeman Dyson, John Wheeler, Martin Rees, Steven Weinberg, etc. But if we go back in history, there’ve been many other philosophical physicists (from Isaac Newton to Niels Bohr and Werner Heisenberg); many of whom were also very knowledgeable about philosophy.

One must also admit here that being a philosophical physicist doesn’t necessarily mean that such a physicist must also be a very-big fan of philosophy. They don’t need to, say, keep bang up-to-date with all the top academic philosophy journals.

In any case, many physicists have only ever mentioned dead philosophers (i.e., not contemporary ones). The American philosopher and journalist Jim Holt, for example, tells us that when the philosophy of science is brought to the attention of physicists, they always say: “Oh, you mean Karl Popper?”

So is that (at least partly) why these anti-philosophy physicists believe what they believe about philosophy? That is, perhaps they believe that philosophy of science = Karl Popper. Indeed was Popper himself an example of one of those philosophers who (to use Wesley Salmon’s words again) “ignore[d] the actual methods that scientists have found acceptable”?

As stated earlier, it’s very hard to say because most (or all) anti-philosophy physicists rarely cite any details about the philosophy they dislike or see as being “irrelevant”.

In addition, none of the above is to claim that the physical theories of these philosophical physicists were actual examples of philosophy.

Some critics of philosophy have been keen to point this out. Yet the statement that theories in physics aren’t themselves expressions of philosophy is a statement of the obvious.

In detail.

Critics of philosophy (i.e., not only physicists) have felt the need to point out to me the irrelevance of the “context of discovery”. One such critic cited Albert Einstein as an example of this.

He pointed out that Einstein loved playing the violin and that this hobby didn’t impact on his actual physics.

Sure!

But what about Einstein and philosophy?

As if Einstein’s philosophical positions and influences were equivalent to his playing the violin, drinking wine while theorising about physics or being a penniless member of the bourgeoisie.

Is Every Richard Feynman Quote Really Profound and Wise?

The late and great Richard Feynman once famously declared: “Snow is white.” Feynman also quipped that “drinking Earl Grey tea is like making love to a beautiful woman”. Now all that is precisely why The Dick was both a great and a late man.

Why do so many of Richard Feynman’s fans believe that every sentence he ever uttered was profound and deep and worth quoting at every opportunity? In addition, why do so many of Feynman’s words end up in memes and images, which are then spread around Facebook and Twitter like confetti?

(On the goodreads website, there are 24 pages of quotes from Feynman. Each page has at least 23 different quotes on it.)

It’s worth noting immediately that previously (in response to an earlier essay) I discovered that Feynman’s fans often get very angry when someone points out that his fans get very angry when Feynman is criticised. I also noted that many of the writers who actually got around to mentioning the fact that the hero-worship of Feynman really does exists, then go straight ahead and indulge in a bit (or even a lot) of it themselves. (Perhaps to prove that they aren’t philistines or luddites — see here and here. Note that this isn’t a reference to those negative articles which have been written about Feynman’s private life, behaviour and personality.)

In any case, the hero worship of Feynman is very deep and widespread. Of course very few people would deny that he was a great physicist. (Although non-physicists can only believe that Feynman’s physics is great via what philosophers call testimony.) Yet, ironically, most of the Feynman memes and quotes just mentioned are posted by non-physicists. What’s more, nearly all of them are not actually about physics (or even science as a whole) at all.

(I had a problem finding a single meme or image about Feynman’s work on quantum electrodynamics (specifically, Feynman diagrams) and the path integral formulation, which are, after all, what made Feynman famous within physics. Of course this isn’t to deny that he did much other important work too. And perhaps it’s difficult to create a sexy meme about QED, etc.)

It can be argued that Feynman’s fame (at least as it manifests itself outside of physics and physicists) often simply boils down to the fact that he was, well, cool and/or hip. Or, more correctly, it boils down to the fact that Feynman is deemed by many of his fans (often self-described nerds and geeks) to be cool and/or hip. So why was Feynman cool and hip? It seems that Feynman was cool and hip because he played the bongos, “liked a laugh”, was a womaniser, and even had a somewhat quirky face and way of dressing (see here and here).

Thus, Feynman’s image alone (as with many of the fans of James Dean, Che Gevara, Malcolm X, Marlon Brando, Sid Vicious, Kurt Kobain, etc.) is a strong part of the appeal.

Specifically on the endless mentions of Feynman’s bongo-playing. (There are over 7 pages of Google links about Feynman and his penchant for bongos.) The television series The Big Bang Theory accurately summed this up when one of its main characters, Sheldon Cooper (one of the nerds I just mentioned), often emulated Feynman (i.e., in more than one episode) by playing the bongos.

So what about other famous physicists?

The Wise Words of Other Famous Physicists

Why do far too many people (at least those who admire physicists) simply assume that famous physicists (i.e., not any unknown ones) will have insightful things to say on almost (or literally) all other subjects? (I have in mind Michio Kaku, Brian Cox, etc., but especially the highly self-conscious performer Neil deGrasse Tyson.)

I first noted this with Albert Einstein.

Einstein’s non-scientific words are quoted left, right and centre. Yet much of what he said on politics, religion and God is fairly standard stuff. And even when true or fairly insightful, his words would probably have been ignored if said by a layperson or even by an unknown physicist.

Thus, we give the superstars of physics (if not physicists generally) leeway to comment on all sorts of stuff that’s a million miles away from physics. (This is a little like asking pop stars or actors to offer their profound insights on politics.) It’s also a case of a positive ad hominem in that the aforementioned bigged-up men or women are automatically deemed to be saying insightful things simply because they are famous actors, pop stars… or physicists.

In terms of theoretical physicists, I believe that this is primarily because they’re seen as being the “brainiest” of all people — perhaps just behind brain surgeons. (Are brain surgeons “brainy” simply because they carry out surgery on the brain?) Sure, many of them are indeed brainy and even highly imaginative. Yet, again, why does that give them a special insight into Donald Trump, Jeremy Corbyn or “the meaning of life”?

So do economists, psychologists, social scientists, etc. also have some insightful and deep angles on quantum mechanics, string theory or wormholes? It can be accepted that such people could do. However, there’s no reason to simply assume that they do.

The English physicist Stephen Hawking (1942–2018) was a good example of all this.

Hawking talked about politics (see here), religion and, of course, God (see here).

More specifically, Hawking commented on, and was extensively quoted commenting upon, the Iraq War, euthanasia, women in science, Brexit, nuclear weapons, animal testing, Donald Trump, the NHS, the Labour Party, etc. However, as far as I know, none of these comments appeared in his actual books or publications. Thus, if Hawking was asked a question on any given x, then of course he had the right to answer it and offer his view.

So all this is very different from a physicist superstar (such as Michio Kaku, Neil DeGrasse Tyson and, well, Richard Feynman) discussing Black Lives Matter or tax policy in his actual books or articles. In other words, Hawking and others can’t help but answer the questions they’re asked by journalists and others. And there’s no reason that they shouldn’t answer them. After all, physicists are voters, members of society, human beings, etc.

So shouldn’t we expect a little more modesty from such superstar physicists?

That said, since literally millions of people are buying their books, and these books tend to stray way beyond physics, astrophysics and cosmology, then why should such physics superstars stop doing what they do? That is, these theoretical physicists firstly created a niche in (obviously) theoretical physics, etc., and then they branched out… And the more they wrote and got published, the farther and farther out they branched.

Now it must be said that this branching out isn’t always unsuccessful. Indeed sometimes it may even be insightful. However, why do so many of the fans of these physics superstars simply assume that all the examples of this branching out will be interesting, let alone insightful or profound?

Part Two: The Quotes

It can happily be conceded that Feynman might have had extremely insightful things to say about sexual intercourse or Richard Nixon (see later section). However, why should his fans (or anyone else for that matter) simply assume that he did so? What is it about famous theoretical physicists that gives them an insight into tax policy or “the meaning of life”?

It must also be said here that I too can appreciate at least some of Feynman’s words on subjects which have nothing (directly or even indirectly) to do with physics.

Take this (possibly) unanswerable (if ironic) question asked by Feynman. He recalled:

“You know, the most amazing thing happened to me tonight. I saw a car with the license plate ARW 357. Can you imagine? Of all the millions of license plates in the state, what was the chance that I would see that particular one tonight? Amazing!”

This passage can be reformulated as a simple question:

Of all the millions of license plates in the state, why did I see that particular one tonight?

Yet it’s not at all weird that Feynman should have seen that particular number plate. He had to see one number plate when he glanced at that particular time. So whichever numberplate he saw, the same astonished question could have been asked about it.

So, to admittedly stretch things a little, perhaps Feynman’s ironic question is similar to the following non-ironic question:

Why are the laws of physics and the constants of nature the way they are and why do they have the particular values that they have?

Yet perhaps there’s no deep answer — other than mundane facts about probabilities, etc. — to Feynman’s own question as to why he should have seen that particular number plate.

Basically, then, what if these deep questions don’t have answers (or solutions)? Moreover, what if these supposedly profound questions are suspect or bogus in some way? Despite stating that, even if a question may not have an answer, reasons or explanations will still need to be given as to why that’s the case.

No One Understands Quantum Mechanics

There’s only a single well-known quote from Richard Feynman which I’ll spend a little time on. However, I have no idea where this quote comes from. That’s because, like so many other people, I’m simply quoting the quote. So here goes:

“I think I can safely say that no one understands quantum mechanics.”

To be honest, I find Feynman’s remark to be almost purely rhetorical. After all, it’s fairly well-known that Feynman didn’t have too much time for the interpretations of quantum mechanics, let alone for the philosophy of quantum mechanics. In other words, Feynman knew all of the relevant maths. “The trouble was”, as science writer Philip Ball put it, “that’s all he could do”.

The physicist Christopher Fuchs (also quoted by Philip Ball) expressed the problem with quantum mechanics in terms of “all the posturing and grimacing over [its] paradoxes and mysteries”. Indeed, for many laypersons especially, that posturing and grimacing seems to have become the very essence of quantum mechanics. And perhaps this is even the case for some physicists too…

And from that quantum weirdness there follows the no-one-understands-quantum-mechanics refrain.

So Ball picks up on the bizarre nature of Feynman’s statement when he says that “[a]t that point, no one alive knew more than Richard Feynman about quantum mechanics”. He concluded: “What hope is there, then, for the rest of us?”

On the other hand, it’s easy to agree with Feynman. So it’s not a surprise that Ball says that “[s]ome scientists feel the same way today”. Many scientists, in the words (quoted by Ball) of the physicist David Mermin, also say “shut up and calculate”.

Now for some more Feynman quotes which aren’t technical or even about physics.

Ten More of Feynman’s Oft-Quoted Words

(1)

“Nobody ever figures out what life is all about, and it doesn’t matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough.”

That’s okay advice. However, it’s still pretty banal. Indeed it could have been said by very many science teachers and physicists — and probably has been. (Perhaps some of Feynman’s fans wouldn’t deny that.) And it also assumes that “life” (whatever that is) is “about” something, even if we can’t discover what it is about. That said, Feynman did concede that it “doesn’t matter”. In addition, I don’t believe that many (or even any) people are psychologically constituted to find “nearly everything” interesting.

(2)

“Religion is a culture of faith; science is a culture of doubt.”

That has been said (if in different ways) by countless scientists (countless times) over the centuries (though especially since the 19th century).

(3)

“I would rather have questions that can’t be answered than answers that can’t be questioned.”

Ditto.

(4)

“If you thought that science was certain — well, that is just an error on your part.”

Ditto.

(5)

“It doesn’t make a difference how beautiful your guess is. It doesn’t make a difference how smart you are, who made the guess, or what his name is. If it disagrees with experiment, it’s wrong.”

Ditto.

(6)

“I’m smart enough to know that I’m dumb.”

That’s fairly witty. However, it could well be a witty variation on Socrates’ well-known words — “I believe that I know nothing”. It also includes an obvious bit of vanity, which is, nonetheless, hidden underneath the false modesty. That is, Feynman seemed to really be saying this:

I’m so damn clever that I’ve also realised that I’m not omniscient.

So now read these words from Peter Woit:

“I avidly read the Feynman anecdote books when they came out and was suitably entertained, but I also found them a bit disturbing. Too many of the anecdotes seemed to revolve around Feynman showing how much smarter he was than someone else.”

(7)

“Physics is to math what sex is to masturbation.”

It’s probably quotes like this which appeal to many of the non-physicist fans of Feynman. It’s witty and sexy, sure. However, if taken literally, then its meaning — or even truth — would quickly evaporate.

(8)

“Philosophy of science is about as useful to scientists as ornithology is to birds.”

Physicists love quoting this. And those who dislike philosophy can’t resist quoting it either.

There are so many problems with that — yes, witty — statement that it would take an entire article to tackle it. (Indeed I have done so.) But, then again, I’m probably as biased on this subject as Feynman was.

(9)

“The highest forms of understanding we can achieve are laughter and human compassion.”

I have absolutely no idea what that means. Even in purely grammatical terms, it’s almost meaningless. So perhaps it’s poetry. Perhaps only someone as wise as Feynman (or one of his fans) could know what it means.

(10)

“Physics isn’t the most important thing. Love is.”

Pass the sick bag.

And so on… ad infinitum.

*************************

Note:

It’s worth saying that some physicists and commentators have said that Richard Feynman’s contribution to physics has been overexaggerated. (Indeed some have gone even further than that.) Personally, I’m not one of these people. However, that may simply be because I’m not a physicist myself. Thus, I’m not really qualified to say either way. That said, my not being qualified to comment on Feynman’s actual physics (at least not with any original or insightful words) puts me in exactly the same position as many — or even most — of his fans.
