Compulsive behaviour is a problem of logic

Compulsions and Anti-compulsions are caused by circular thinking and this is best analysed as a logic problem. This video explains how a simple process of self-reference–a person can impersonate their own behaviour—leads to circular reasoning that manifests itself as a compulsive action state. This gives us a clue as to the mechanism by which mental illness operates.

Why pretending to be happy will make you miserable

In this video, my first on YouTube, I explain why pretending with your emotional behaviour has unintended consequences. Using the example of “happiness” behaviour, I demonstrate why manipulating this behaviour will be self-destructive over the long run…

The “medical model” of mental illness is not a model

Psychiatrists talk about the “medical model” of mental illness, and yet no such model exists as other scientists would understand it. In science, a model is a hypothetical representation of the relationships between phenomena that permits scientists to make calculations, predictions and comparisons with empirical observations. To illustrate this it is helpful to describe how scientists from diverse disciplines use them.

Meteorologists use models to predict future weather. The inputs are millions of data points including temperature, pressure, wind and tides. The models connect all this data into patterns from which expected future weather systems are extrapolated. The models are complex and messy, in part because generations of meteorologists have tweaked and manipulated them whenever new wrinkles in weather patterns are observed. However, if the predictions are approximately right, everyone is happy.

Physics, by contrast, creates models of sparse minimalism, inputting basic atomic building blocks, such as mass, charge and force, and connecting them using advanced mathematics to explain theories of the universe. A model of particle physics projected the existence and nature of the Higgs Boson long before it had been observed. Its later discovery, complete with the predicted qualities, demonstrated that the theory was likely correct, and the model accurate. Unlike meteorology, approximate accuracy in physics can mean being wrong.

These two modelling approaches represent two ends of a spectrum, but psychiatrists’ “medical model” of mental illness fits nowhere on this spectrum. Perhaps that is why it is usually written with inverted commas.

R W Pies highlights psychiatry’s confusion by describing three different understandings of what the “medical model” represents. The “hard model”, assumes that a mental illness is a brain disease that is a form of physical illness. Pies rejects such a model since it pathologises a wide range of human psychological experience. However, the hard model assumption underlies much of neuroscience’s research into schizophrenia, for example, where they seek correlations with gene or brain abnormalities.

Pies’ second version was set out best by the philosopher Murphy, who described mental illnesses as, “regularly co-occurring clusters of signs and symptoms that doubtless depend on physical processes but are not defined or classified in terms of those physical processes.” This conception, says Pies, is the foundation of the Diagnostic and Statistical Manual. Essentially, this model says that mental illness is like a disease, purely because it has observable symptoms.

The third version Pies mentions is how most practicing psychiatrists understand it. Shah and Mountain ignored biology and focused on treatment as, “. . . a process whereby, informed by the best available evidence, doctors advise on, coordinate or deliver interventions for health improvement.” This view relies on circular reasoning, appearing to state that mental illness follows a medical model purely because doctors treat it.

All these descriptions share one failing: no other scientist would recognise them as models at all. What are the input factors? What are the relationships between phenomena that they describe? There has been no model of psychiatry (medical or otherwise) because there has been no theory. Psychiatry, at its current stage, is comparable to physics before Newton or biology before Darwin, merely describing phenomena without providing explanations. The “medical model” is a forlorn finger pointing in the direction from where it is hoped the explanatory theory will eventually come.

In The Logic of Madness, I described a true model of mental illness that is not medical, but logical. In the syllogism “Fido is a dog; all dogs go meow; therefore Fido goes meow” the initial view is that the second axiom is factually false. Since this is logic, it would naturally follow that the conclusion would be false, and this would appear to be the case if Fido is indeed a dog and not a cat. However, there is a second interpretation: If I am of the belief that the word “meow” is the correct word for the sound that a dog makes, then the second assumption “all dogs go meow” is factually correct, but for an error of language. And since this is logic, it follows that the conclusion is also factually correct, but for that same error of language. If Fido is a dog, it would indeed make a sound that I (and only I) call “meow”.

Putting this into a human context, a psychiatrist might encounter a patient who chews razor blades (to pick an intentionally obtuse example). The patient might say “I want to be happy; chewing razor blades causes happiness; therefore, I will chew razor blades”. A conventional reading is that the idea that chewing razor blades causes happiness is irrational, and the psychiatrist would likely think the patient mentally ill. But what is irrationality? Is it an absence of reason, or could it be that there is a reason that other people cannot see? Here, we can deploy the second interpretation of the Fido syllogism: if the word “happiness” is an error of language, it is possible that the statement “chewing razor blades causes happiness” could be a factually true statement, but for that error of language. This would make the resultant action a rational response to a mis-identification of an emotion. Misunderstanding our own emotion can have bizarre and dramatic consequences.

Emotions are biological mechanisms found in social animals: a set of circumstances (for example, danger) triggers a mechanism (fear) that causes an action state (running away) and a behaviour state (a grimace). The action state promotes survival, and the behaviour state is a signalling mechanism to incite similar survival responses from other members of the social group.

The primatologist Franz de Waal observed chimpanzees and recognised that anger is a mechanism for punishing cheaters in social obligations. It is therefore a regulator of animal societies. But observing this in humans is difficult because we use tactical deception with the behaviour. Emotional behaviour may be either suppressed, or affected by individual humans for tactical reasons, and this deception can become habitual. Emotional behaviour in humans therefore does not correlate with biological stimuli, making scientific analysis impossible. This diversity is seemingly so great and random that many humans (including some scientists) think of emotions as mystical.

Ultimately, we can only understand an emotion by observing emotional behaviour, but we all live in a social environment where that behaviour has been manipulated. In essence, most of the behaviour we observe is false data. Observations of manipulated behaviour make us derive a false understanding of our emotions. Understanding how humans can misunderstand their own emotion requires us to consider, in the abstract, how each form of tactical deception changes our understanding into a misunderstanding. The separate forms of misunderstanding can then be tabulated systematically. Elevating this to higher levels of complexity enables us to deduce the misconceptions that result in the anomalous responses that psychiatrist see every day in their patients.

We can construct a true model of mental illness where the inputs are biological descriptions of emotions and evolutionary theory. And the principal analytical method is logic. Deception with emotional behaviour causes misunderstanding of the emotion, and how this will lead to dysfunctional action can be analysed by deduction.

Diagnosing Trump with narcissistic personality disorder–some dangers:

Allen Frances wrote an Op-Ed in the New York Times ‘An Eminent Psychiatrist Demurs on Trump’s Mental State’ expressing the opinion that Donald Trump does not meet the criteria for narcissistic personality disorder. He bases this view upon the assertion that he cannot have the condition because he does not suffer from distress and impairment. His argument has three flaws:

He claims authority for his view because he wrote the criteria for narcissistic personality disorder for the DSM-IV. This is just a drafting exercise and his claim that he knows what the condition is because he wrote the criteria undermines a vast literature on the subject. The claim is a tautology along the lines of “I know I am right because I said so”.

Secondly, the general criteria for personality disorder requires “distress and impairment in social, occupational, or other important areas of
functioning”. He is no position to claim that Trump does not experience this. Narcissistic personality disorder is usually egosyntonic, meaning that narcissists like the way that they are. They believe that everybody else is also obsessed with obtaining admiration, and if they have achieved this aim then everybody else is envious of them. They rarely seek therapy and, when they do, they resist and manipulate the therapist who they see as undermining what makes them great. Psychiatrists who only treat patients who voluntarily consult them have systemic sample bias–all their patients self-identify as distressed and impaired. If people with egosyntonic personality disorders do not so self-identify, why did Frances include such conditions in DSM-IV at all?

Lastly, he criticises those psychiatrists who breach the ethical constraints against diagnosing celebrities at a distance. And yet he is also doing this. He supposes that Trump does not suffer distress, but he cannot know this without examining him. Narcissism is a defence mechanism that conceals an inner state of rage, emptiness and intense envy. His assertion that Trump does not experience this is diagnosing at a distance. He also cannot say that Trump is not impaired. Trump is unique among narcissists in that his wealth has enabled him to purchase the admiration that he craves, and he has been able to mask his impairment by acquiring unlimited sycophants and fixers. But his brief career in politics is already revealing that his unreasonable belief that he knows more about foreign policy than the State Department and more about security threats than the CIA is leading to undeniable severe impairment.

The mechanism of Personality Disorder

Imagine you are teaching a small child a word for an emotion. You might start by saying when the child is naughty “your mother is angry”, and when you do this you refer the child to an attribute of the mother, namely a behaviour state. On another occasion, you might ask the child “why are you angry?” when it displays that same behaviour state. Without the behaviour state, we could not know that another person was angry. The ability to compare our behaviour with that of others is necessary for the process of giving a name to it, but that is not the reason for the behaviour.

Charles Darwin explored this in his least read book “On the Expression of the Emotion in Man and Animals”. Emotional expression exists in many mammals, particularly social mammals and serves as a signalling mechanism that enables animals to communicate intentions, desires, warnings, etc. This is very necessary in social mammals that don’t have language. Humans have evolved language, but still retain the emotional expression.

Later, you might ask the same child “are you feeling angry?” and piece-by-piece the child builds a concept of anger that we could describe with the following diagram:

genericemotion-page-001

We can separately think about how a scientist and a child each understand this. The scientist can draw upon evolutionary theory, the study of this in animals such as chimpanzees, and observations of humans. I drew the “feeling state” in a dotted line box to indicate that no scientist understands its nature. It is a state of consciousness and this remains a thorny philosophical problem. I also drew the associated arrow as a double headed dotted line because nobody knows which direction the causality flows. Strangely, anger is much easier to understand in chimpanzees: I groom your fleas; you do not reciprocate; I jump up and down and scream at you. This simple point is difficult to determine in humans because they manipulate anger behaviour tactically, often suppressing it in particular circumstances. From a scientist’s perspective the link between causal trigger and the behaviour state is patchy at best and immeasurable at worst.

A child understands this within the context of their family. However, it is clear that anger is a mechanism for punishing those that cheat in social obligations and is essential for regulating the interactions of social animals. For the child, it is a mechanism for teaching it what is and is not permitted, and for the child to make it clear when others are cheating.

Let us now consider how this works in a family that habitually suppresses the behaviour associated with anger. If the behaviour is the only means of identifying the emotion, then that identity is uncertain. However, the child will only suppress the behaviour itself when it is trained to do so, so initially it will display the behaviour. Imagine that a parent reacts by saying “Such behaviour is shameful!” Two things are happening here: firstly, the parent is training the child to suppress the behaviour; and secondly, they are suggesting the name of another emotion, shame, in circumstances where the child is lacking behavioural clues for the emotion because he or she is living in a family of anger suppressors.

If this happens for two emotions separately, then it is possible that the child can grow up mistakenly recognising anger as shame, or some other mistaken pairing. How will this affect them in adulthood?

A chimpanzee reacts to a stimulus and has a limited ability to second-guess that reaction. But a human has a number of capabilities that the chimpanzee does not have: naming emotions (possibly incorrectly); manipulating behaviour tactically; and predicting future emotion (also possibly incorrectly). Actually, a chimpanzee has a limited ability to suppress behaviour, but probably no ability to affect it. This enhanced ability to understand our emotions (and therefore to misunderstand them) creates all sorts of complications for humans. Human reason depends upon an ability to predict the future and understand how we will react to it. The invention of agriculture required us both to predict that food would be scarce in winter and to understand that this would mean that we would be hungry. A chimpanzee won’t seek food until it is hungry, but a human predicts future hunger and calculates the action it needs to undertake now to avoid its future occurrence. This could mean planting seeds or going to the supermarket.

Imagine that the child in our example is calculating the action it needs to take to avoid future anger, but it is misidentifying that emotion as shame. It will calculate the wrong response to that predicted future; most probably it will withdraw for fear of doing something that prompts the disapproval of others. You might imagine that this would only happen occasionally, but this is a person who suppresses anger and therefore lacks a mechanism for punishing the asocial actions of others. They are therefore likely to be the target of them more and to have no means of dealing with it. Therefore, they feel its consequence more severely.

They convert the anticipation of asocial actions of others into the avoidance of the disapproval of others. This is a set of symptoms approximating avoidant personality disorder.

There is no scientific hypothesis as to the cause or structure of personality disorder. But if this logical hypothesis is correct, that would not be surprising. The deviant actions of the patient are triggered by an anticipation of a future emotion––something that a scientist cannot see or measure. We cannot ask the patient why they are reacting as they do because the reaction is to a misidentified emotion. There is no empirical way of determining that the patient is doing this because the only evidence of an emotion is someone else is behaviour. And this patient is suppressing it both for the emotion being misidentified and for the emotion that they think it is. All the causal elements are invisible and a scientist without data is like a fish out of water.

Can it be rational to be delusional? A model for schizophrenia.

Many emotions drive the rectification of a bodily need – for example, hunger drives seeking nutrition. Nutrition is a finite upside and the strength of the urge is proportional to the urgency of fulfilling that need. There is very little that science can say on this because it is impossible for a scientist to measure the strength of the urge. That can only be seen in the consciousness of the urged. When two urges that drive seeking a finite upside coexist (say you are hungry and tired) then the relative strength of each urge determines in which you order you will seek to rectify the respective bodily need. We could say that the greater urge is dominant.

Some urges drive escaping an imminent infinitely negative outcome that we usually call death. If two urges coexist, where one drives seeking a finite upside and the other drives escaping an infinitely negative downside (say you are tired whilst fleeing a predator), then the former can never dominate the latter. And the simplest way to ensure that this does not occur is to switch off all emotions that drive actions with finite upsides. I speculate that this switch is a primary function of dopamine in the human brain.

When you experience the dopamine rush that you get on a rollercoaster, it might feel like a euphoric positive emotional experience, but it probably arises through the simultaneous switching off of all negative emotions (hunger, tiredness, pain, etc.). Your brain interprets the steep drop down the initial swoop of the rollercoaster as a near-death moment, and it responds by switching off all awareness of such negative emotional experience. It is quite difficult to come up with an explanation of the evolutionary origin of a positive emotion.

Humans seek emotional fulfilment through acts of pure imagination (e.g. imagining being in bed with the object of your sexual fantasy, or having an imaginary friend). Another seemingly paradoxical way to achieve this might be to imagine a near death experience. It is conceivable that, by doing this, you could train yourself to trick your brain into releasing dopamine, and you could do this at will. This would achieve a euphoric emotional rush – the best conceivable emotional outcome. If human wellbeing is measured in emotional outcomes, then it is rational to do this. In fact, once you had perfected the technique, it would be rational to do it for all your waking hours. People who are not psychotic tend to imagine that the manic phases of someone with psychosis must be hell. But imagining hell may be the whole point. If that is the case, then psychosis is a motivated self-deception with the rational objective of seeking a favourable emotional outcome. Psychotics often say that they only feel truly alive when manic.

It is a source of frequent frustration for psychiatrists and family members of psychotics that they relapse by refusing to take their medication. But if this model of psychosis is correct, then it is even rational to stop taking your meds, since the “cure” is cutting off an avenue to positive emotional experience. Only the psychotic can know whether this is a price worth paying or not.

The brain as a self-referencing mechanism

The following is an extract from Matthew Blakeway’s book, The Logic of Madness:

When I lived in Brooklyn, the shoreline of New York Harbour had huge granite boulders that had been put there to prevent tidal erosion. Whenever I got bored (i.e. most days) I would walk to the harbour and jump from boulder to boulder until I was at the water’s edge. Once, when I was doing this, I imagined slipping and falling between the rocks, and a numb sensation spread through my legs. I have noticed this happen on several occasions and it can sometimes occur when I think of someone else having an experience that would result in serious leg injury. For example, it once occurred when I was in the park and a small child painfully fell off her bike.

We know that the brain has several ways of registering pain, and once registered there are different responses to it. The most likely explanation of my numb feeling is that my brain released endorphins; this is an abbreviation of ‘endogenous morphine’, a form of opioid that exists naturally in the brain. It is released in certain situations of extreme exertion or threat and has an analgesic effect: it neutralises the sensation of pain. This is a brain routine kicking-in that has the purpose of managing pain, and the effect is that my legs felt numb. I am not particularly interested in researching long theses on the neuroscience stuff because I am going to follow a completely different line of enquiry.

What interests me is that an act of pure imagination can trigger an alteration in my brain state. The alteration in my brain state is supposed to be a reaction to real external events, such as actually breaking my leg or being chased by predators. If a pretended event that exists only in my imagination can cause these changes, then that means that a human brain can do something that a chimpanzee brain almost certainly cannot do. A chimpanzee does not have language and that limits its ability to form concepts. That in turn limits its ability to think in hypotheticals. It would be a fairly conventional view for both philosophers and animal behavioural scientists to suppose that a chimpanzee cannot speculate about a predator that is not actually there or a traumatic leg injury that has not actually happened. However, we all have to admit a certain level of philosophical doubt about this.

A human is a self-referencing mechanism. Computer scientists understand that self-referencing is the origin of circular causality. If you write ‘=A1’ in cell A1 of a spreadsheet, then the memory cell self-references. The self-reference prevents the cell from computing any meaningful answer and the spreadsheet would be considered to have a circular argument. In old-skool computer programming language we write sequential lines of code. If at line 42, we tell the programme to go back to line 41, then the programme (rather than the memory cell) self-references. Unless the code at line 41 sends it somewhere else the programme will keep repeating lines 41 and 42 until someone pulls the plug out. Self-referencing is a pre-requisite of circular causality, and I have been focusing on the fact that humans self-reference in a way that has no equivalent in any other system that I can think of: we impersonate our own behaviour. Neither chimpanzees nor computers can do this. My work is mostly about exploring the consequences of this self-reference. When a human does this, it has consequences that could include circular causality. The models of compulsive action that we explored in Section B: Compulsions, all involve feedback loops that never switch off¾an unusual consequence of the corruption of a biological system that is supposed to promote survival. Until we understand all the possible causal pathways that this self-referencing might drive, we will never understand ourselves.

If an act of pure imagination – in other words something that occurs in my brain¾can trigger a change in a brain state¾something else within my brain – that is supposed to be a reaction to something in the external world, then this is a self-referencing mechanism of an entirely different nature. What causal pathway could this set off? The one thing that is fairly certain is that these are pathways that are not the product of an animal that is a ‘survival machine’ in the shorthand of evolutionary theorists. It is a pathway that is more appropriate to a ‘machine that is goal-seeking emotional outcomes’, since I have now stumbled upon a way that I can change my emotional states by acts of pure imagination. I speculate that this could lead to hypothetical explanations of rational actions that would be recognised by psychiatrists as being mental disorders.

Psychiatry makes distinctions between neurosis, acute personality disorder and psychosis. These distinctions have been recognised since the nineteenth century. The logical structures that we constructed in Section B: Compulsions would fall into the category of neuroses and those in Section C: Impulsions would fall into the category of acute personality disorder¾what I would simply call a rationally derived self-destructive action of a compound nature. A psychosis is something beyond this¾a state where somebody appears to have completely lost touch with reality. A ‘delusion’ means more or less the same thing to a psychiatrist as it means to a layperson: a belief that is wildly different from observed reality. The difference between imagining something and believing it is quite subtle. It is clear that the writer J. R. R. Tolkien did not believe in Middle-earth, although The Lord of the Rings is clearly allegorical since it was inspired by the horrors of Nazism and World War II. It is not entirely clear whether a Hindu believes in Ganapati or that an evangelical Christian really believes every word of the Bible. What I am suggesting is that if an act of imagination can trigger a change in a brain state, then this is a form of self-reference that opens up a world of possibility for emotional gratification. If we assume a human is a totally rational actor that is a machine that goal-seeks emotional outcomes, then how can a human think that he is the Pharaoh Sekhemresewadjtawy Sobekhotep III, or that he is being pursued by hideous monkey demons? Can we construct a hypothetical situation where thinking this is an entirely reasonable thing to do?

 

The concept of madness

The following is an extract from Matthew Blakeway’s book, The Logic of Madness:

Madness, melancholy, insanity, lunacy, craziness, unsound mind, mental disorder, unreason, loco, mental illness – a dizzying array of words has been used to describe a condition that we have never truly understood. In each age, there has been an accepted way of discussing this subject depending upon how the condition was perceived. The term ‘lunacy’, for example, stems from the ancient belief that madness was caused by the moon. The classical term was ‘melancholy’, even though it was recognised this could include unreasonable ecstasy. In times when madness was seen as benign, people with this condition were known as ‘holy fools’ or ‘idiots’. In times when madness was feared or subject to prejudice, the terms used sounded derogatory, such as ‘insanity’ or ‘unreason’. When philanthropists, such as Daniel Tuke, took over responsibility for the management of the mad in the eighteenth century, we changed the terms to reflect a more humane approach. He adopted the French term ‘mental alienation’. This, he said ‘conveys a more just idea of this disorder, than those expressed which imply, in any degree, the “abolition of the thinking capacity”’. Then, in the nineteenth century, physicians became involved in the study of madness, and we started to call it ‘mental illness’. General concept words started to sound technical, medical, or were simply spoken in Latin.

Sigmund Freud completely changed how we talked about and understood ourselves, where everything was discussed in terms of madness. For half a century after his death, everybody thought that he or she was a psychiatrist, and it was normal to diagnose your own neuroses and complexes, as well as those of your friends. Everybody was a ‘crazy mixed-up kid’. These ideas were applied to society as a whole, ultimately leading to the ‘psychiatrisation’ of everything. Even sociology became a branch of psychiatry with widespread talk of juvenile delinquency and the degenerate society.

Psychiatry today tends to avoid the term ‘mental illness’, since an illness implies something wrong with the functioning of the physical body. Instead, the term ‘mental disorder’ is considered more appropriate. This change of nomenclature does not disguise the fact that the field of psychiatry is still not certain whether mental disorders are caused by a malfunction with the physical brain, such as a neurological or chemical cause, or something ‘psychological’.

To date, there has been no agreed causal theory of madness. We do not even have an explanation of what madness is. We just think we know what it looks like. This is little different from the situation that existed in the seventeenth century. Changing the terms we use disguises the fact that psychiatry is still not even a young science. It cannot become a science until it has consensus regarding a structural theory.

The general aim of my work is to put psychology on the same shelf as alchemy. I do not understand what psychology is or what it is trying to prove. This book will not give madness a new name, but it will explain a theory on how it works and create some new technical terms for different structures. These structures are logical in nature, and once we realise this, perhaps we will need to change the way we talk about madness yet again.

The Anti-Compulsion

The following is an extract from Matthew Blakeway’s book, The Logic of Madness:

Let us take the following to be a model of a very simple human who has got only two emotions, but has still managed to get them into a tangle:

Anti-Compulsion2

This person has one biological emotion that drives action and another that inhibits action, and by a compound manipulation of the behaviour, they have found themselves in the situation where the Biological Stimulus for the driving emotion has become the Affectation Stimulus for the inhibiting emotion; so only the behaviour for the inhibiting emotion is displayed. We can consider first the two emotions separately, and then look at the inter-causality that relates to the crossing over.

With respect to the inhibiting emotion, our hypothetical individual is affecting the inhibiting emotional behaviour, and so has an incorrect belief that they are identifying the inhibiting emotion in themselves. This simply acts as a constraint on action, because with inhibiting emotions we do not get the inversion of causality that arises with driving emotions.

With respect to the driving emotion (in isolation), they suppress the behaviour and are therefore able to recognise that emotion in other people, but remain unaware that they are experiencing it themselves. The biological emotion is supposed to drive an action, but is not doing so in this case. Clearly, this situation is self-destructive in isolation: they think they are experiencing an emotion that inhibits action. Therefore, trying to compute an action that achieves a future emotional goal is irrelevant in this case. To optimise their biological fitness, they should be calculating the action that the driving emotion is supposed to drive. However, they do not acknowledge that they experience it because they do not demonstrate the behaviour.

Let us consider the impact of the crossing-over.

Driving emotions are feedback mechanisms. They arise because the human (or animal) needs to rectify something, and the stronger the need to rectify, the stronger the emotional urge. A human, at any point in time, will have multiple emotions, and the one that is strongest will tend to become dominant over the others and drive the action that occurs next. If you are both hungry and thirsty, then the stronger emotion will determine whether you drink or eat first. This action cancels out the urge to act. Here, the driving emotion is an Affectation Stimulus for an inhibitor; so the action does not occur and the feedback mechanism is broken. Failure to act on the driving emotion results in it becoming steadily stronger, leading the inhibition to become all-embracing and eventually consume the individual. The inhibition will become this individual’s dominant emotion on an almost permanent basis. The negative feedback mechanism has turned into a positive feedback mechanism, where the urge to not act keeps getting stronger. This is a compulsion to not do something that biology dictates you should do¾what I generically call an ‘Anti-Compulsion’.

What would happen if 3-D printers could 3-D print themselves?

The French philosopher and economist Jacques Attali[1] predicted in the 1970s that the music industry would collapse. He was proved right within twenty years. If something is freely or cheaply replicable, then economic theory will predict that its value will trend towards zero. Even before the digitisation of music, we were able to record our friends’ vinyl LPs on cassette, and the ability of musicians to earn a living from recorded music was doomed. So it turned out to be. And musicians today earn less and less from selling recorded music. As a writer, I am acutely aware that it is getting harder to make a living, even in a world where people are reading more.

Attali is now making the same predictions about manufactured goods. 3-D printing is still a relatively new technology, but it opens the door to being able to scan any object into a 3-D printable file and to email it. Any manufactured product is now infinitely reproducible, so its value will fall to zero. It isn’t inconceivable that we will soon be able to upload the 3-D printable files for a car or refrigerator that we can print at home and assemble Ikea-style. We could then tweet the link so everybody can have one.

At first glance, this all sounds like an impressive advance of technology. But actually, it is anti-technological – just like music streaming is anti-creative. The incentive to invent a better car or refrigerator is to make money, but if as soon as you have done so the value of the inventor’s work is zero, then all hope that the inventor has of making money evaporates. So what is the point of innovation?

We could argue that the same argument applies to inventing a new music genre. We like to think that people will continue to do this for the love of it. But I remember a time (not long ago) where all waiters and bar tenders in New York City were aspiring actors, musicians or artists. They could survive on three shifts a week and devote the rest of their time to their creative pursuits. But today, it takes six shifts to support subsistent living in a grotty bed-sit, so all those creatives have disappeared. I hope they went to another, better place, but I see a lot of anecdotal evidence that they were all forced to take menial office jobs instead.

If all forms of creative output (artistic or manufactured) will eventually become valueless in economic terms, then the economic constrains upon consumption will evaporate (like it already has with music), but then so will all the manufacturing jobs that create that stuff and so will all the artists and inventors.

There is something else on planet earth that is infinitely and cheaply replicable – and that is humans. During my lifetime, the population of humans on this tiny planet has doubled and, if I survive into my eighties, it will treble. If something is freely and infinitely replicable, then in purely economic terms its value will trend to zero. And that is precisely what is happening across the world. The value of unskilled labour is trending towards subsistence wages, and in a globalised world, nations that value “human rights” are powerless to protect their unskilled workers from the market forces of labour in countries far away that have too many people doing jobs of declining worth. Real wages of American workers have declined even as their productivity has increased[2] . This divergence started in the 1970s, just as economists started preaching the value of globalisation. In the developed world we have been trying to resist this trend by pouring resources into education – attempting to ensure that we have no unskilled workers. But this post started by explaining why the value of the output of skilled creatives is also falling to zero – so this strategy only defers the inevitable.

The logical conclusion of this is that people whose labour has no value will have no economic constraints on the consumption of products that cost nothing to produce. Increased productivity should reduce the need to work, but that is not the experience of workers everywhere who are working harder just to stand still. Playing devil’s advocate, we could argue that goods cost nothing to produce except for the cost of raw materials – but commodity prices are universally declining too.

We need to ask what this means for the future of mankind. But before we can do this, we need to ask what it means for the future of economic theory. It occurs to me that most economic theory doesn’t work in a world where there is an infinite supply of everything and therefore everything costs nothing. If everything costs nothing, money no longer works as a means of allocating access to resources. This sort of argument isn’t trivial, and economists are currently debating different forms of the same thing: they worry about what happens when the conventional tools of economic management (changing money supply, tax rates or interest rates) simply stop having the effect that they used to have. Some governments have already tried negative interest rates after an interest rate of zero was found not to be low enough to stimulate growth and recovery from recession.

The only way to escape this death spiral where ultimately the planet will have billions of economic migrants, is to abandon the idea that all decision making should revolve around money. We need to stop thinking about the monetary value of labour and start thinking about the emotional value of a human life. A good place to start is to consider how much consumption optimises it. Since the advertising industry has been pummelling us with propaganda about how consumption enhances our emotional wellbeing, it seems likely that we need a lot less consumption than most of us currently think. Then we can start to consider how much consumption this planet can support. And it then becomes easy to compute how many humans we can fit on this planet before it bursts. If economics is going to have any role in working this all out, then it is going to have to go cold turkey on its addiction to converting everything to a monetary value before it can even think about it.
