Don't tell anyone


One of my bugbears these days, and really since the beginning of my life, is secrecy. I don't trust people who keep secrets. Of course, if they keep secrets then they don't trust me either. So it's mutual.

Secrecy is not the same as confidentiality. When something is to be kept confidential, it's pretty clear what the harm would be if the information came out. In my professional life, it could be a reference letter in which a scientist evaluates the work of another. In personal matters it could be someone's love life. There is in fact a right to privacy and it needs to be respected.

But secrecy is a way for the powerful to remain powerful, and to protect abuse of power. Secrecy of this kind is for some people a way of life, a culture, a cult. Those who subscribe to it know exactly when to keep their mouths shut, and follow their instinct firmly even when their actions are both morally repugnant and risky. Some of the plainest examples are of priests in the Catholic church who were known to have sexually abused children. On all too many occasions, the first impulse of their seniors in the church was to cover up. The list of such cases is incredibly long and without cover-ups it would have been a lot shorter.

Outside the church, Penn State football coach Joe Paterno covered up repeated acts of molestation by his former assistant coach Jerry Sandusky. In the end the latter was caught and punished, and the former disgraced in consequence. As the Wikipedia entry points out, "while Paterno did not violate any laws, anyone with knowledge of possible sexual abuse against minors had a "moral responsibility" to notify police. Despite the gravity of allegations against Sandusky, Paterno did not notify state police." And here's the key point: Paterno was not himself a molester. He would have lost nothing, and gained a lot of glory, besides doing the morally correct thing, had he blown the whistle on his assistant as soon as he came to know about it. From this perspective, his action (or rather lack of it) is more inexplicable than that of Sandusky.

At work, I've found myself constantly at war with the culture of secrecy. In the 1980's, as a very junior faculty member in TIFR I was in charge of coordinating graduate courses. But decisions, including those affecting these courses, were taken by the faculty of which I was not a member - because until 2004 (yes that recently!) junior faculty at TIFR could not be called "faculty" or attend faculty meetings. What terrible state secrets would they have stumbled on, one wonders? The result was that as course coordinator I had no input into faculty decisions, and whenever they made a decision that affected my functioning they didn't even have the decency to inform me. This is not a formula for creating a healthy working system, so the system remained dysfunctional for a long time. That however did not seem to bother anyone. The important thing in this case, as in so many others, was that secrecy was more important than a functioning system.

In the good old days Indian Airlines would carefully hide information from passengers. The departure time of a flight might have long passed but the notice board would stubbornly show "on time". No one was ever told what to expect next. Things are not that much better today, since some genius invented the winning line "the flight is delayed due to late arrival of the incoming aircraft" as though that explains anything at all.

Even within my extended family, secrecy has taken on a primary role these days. Not wanting to reveal family secrets to the public (oh now I'm doing it!) I can only mention that senior people are refusing to part with a simple piece of information even though releasing it would spare themselves from accusations of wrongdoing. The natural presumption in such a situation is that the concerned persons are covering up something. And while they might well be, it's also possible that they're not. Perhaps the reason they won't release information is that they are devout followers of the secrecy cult and they understand that once you start revealing things then, really, there's no end, is there? A guilty conscience is more powerful than actual guilt.

When the Right to Information act was passed in India a mere seven years ago, I was very happy about it and I still feel that way. Despite the comments I hear all the time about its potential for abuse, it is brilliant because it offers every Indian citizen the right to know what public institutions are up to. This has struck deep into the culture of abuse of power in our country. If that culture is not yet dead it's only because it's a monster with many heads and Terminator-like powers of regeneration. So secrecy remains the default. I'm reminded of a joke told about a leading organisation of the Indian government: the head of the institution calls his assistant and whispers "I've received an Office Order from the Central Vigilance Commission that we are required to have a Transparency Officer. But don't tell anyone!"

Paper is for sad souls


In the early 1990's, I took a bet with the Chairman of my department that by the year 2000, printing on paper would become obsolete and people would take to reading on their computer screens. I lost the bet, but was merely a little ahead of my time. Yesterday it was announced that in the UK, sales of Kindle e-books have overtaken print books: 114 of the former were sold for every 100 of the latter.

Now Kindle is not the only way to read e-books. One can download over 40,000 e-books for free, in pretty much any format you like, from the Project Gutenberg website. For those sad souls (and I know quite a few) who think everything downloaded for free is illegal, these books are all completely legal and are free simply because their copyright has expired. The website maintains a list of the most popular downloads on a daily basis, and my readers will be delighted to know that number four on the list is the Kamasutra of Vatsyayana, where one can pick up fascinating recommendations such as: "At all times when kissing and such like things are begun, the woman should give a reply with a hissing sound."

If you are done with ROTFL, let's go back to Kindle. A lot of people think this is a device you need to buy and carry around, and indeed there's a whole range of these e-readers. They have particularly good screen resolutions so you may want to try one of them if you feel computer screens don't do it for you. I prefer to download and install the free Kindle software on my Macbook Air, my iPad and my Android phone.

Once you're done with that, a wonderful new life awaits you. Assuming you have a free amazon.com account (and are not one of those sad souls who refuses to use their credit card over the internet) you can register your credit card once and turn on "1-click ordering". Thereafter you browse the online Kindle store, locate a book you want, order it with - as promised - one click, and immediately download it to your device. Kindle books are reasonably priced, I haven't spent more than ten dollars on one so far. What's more, the next time you start up another of your devices you can download the same book there at no extra cost. And now you can do a whole bunch of things that you couldn't even dream of with paper books.

If you're reading a book on an iPad or other tablet, and open the same book later on your phone, it will automatically offer to scroll to the last page you reached on your previous device. So you can seamlessly switch devices. This enables you to continue your reading in a dentist's waiting room instead of browsing his latest issue of "Root Canal Digest". Of course, for all this your Android phone should have an internet connection, a very minimal GPRS that costs 99 rupees a month is more than enough. You can also read your Kindle books on someone else's device or a computer that runs Linux (for which Kindle software is unavailable) by the simple expedient of pointing your browser to the Kindle Cloud and logging in using your amazon.com details. There are all your books, waiting eagerly to be read. You can carry a hundred or ten thousand books with you on your next trip without worrying about the baggage allowance. Your device will remember how far you got with each book, so no need for bookmarks.

And there's more. If you forget where in your novel a certain character originally appeared, just type the name into the search window and you will be directed to all their previous appearances. If you don't know what a word means, just hold your finger over it and a dictionary definition will pop up. If you don't like small print, increase the size of your font. Kindle re-organises your pages automatically so that each page precisely fills the screen of your device whatever the font size. You can make notes on your book and even (this is weird and I disabled it) view comments made by other readers of the same book. 

Of course you might be one of those ever-present sad souls who says (i) I like the feel of a real book in my hands, (ii) I can't possibly read a book on the small screen of a mobile phone, (iii) I don't have an internet connection, or (iv) I don't want to read books on a "device", the word "device" makes me throw up.

If "such like things" are the case with you then all I can say is, you deserve "a reply with a hissing sound".

This Is For Everybody


I've been a fan of Danny Boyle ever since I saw Trainspotting in the mid nineties - an original and moving journey through the dark side of drug addiction. Next, for me, came Slumdog Millionaire which I instantly loved: the colours and flavours (now I sound like a particle physicist) came across so powerfully that I almost failed to notice the plot. But I greatly enjoyed Boyle's head-on approach to poverty and middle-class India's resulting discomfiture with the movie. People emitted the usual whines about the West highlighting only negative aspects of India. And, in an effort to show the world how we can be simultaneously literal and illiterate, someone tried to convince slum dwellers in Bombay that a white man had called them "dogs"!

A couple of months ago I had a chance to see a movie of a theatrical production of Frankenstein staged by Danny Boyle at the National Theatre in London. This movie has had a limited distribution so far, and I got to see it at the National Centre for the Performing Arts in Bombay, but it has recently been distributed in theatres across the USA and you can read about it here.  You can also watch the trailer of the movie here, as well as the somewhat better trailer of the play here.

It so happens that I recently downloaded the original novel by Mary Shelley (along with a whole lot of other free literature to read using Kindle on my iPad) and finished reading it around April. In terms of literary style it's repetitive, hackneyed and overdone and came across to me as a little mediocre. But it compensates by the brilliance of its plot and the universal appeal of its horror story: a monster who is physically repulsive to his creator and the rest of mankind, and intelligent enough to appreciate this fact, is emotionally shattered and goes around vengefully killing everyone dear to his creator.

Now most people who haven't read the book think the monster is meant to be disgusting (they also think, incorrectly, that the monster is named "Frankenstein"). But if you read the book, it's not hard to pick up on Mary Shelley's hints that the monster is the hero of the tale, the one who has her sympathies. And in the play Boyle (and to be fair, Nick Dear who wrote the script) take this a step further. The play is largely presented in the monster's voice and devoted to his point of view. It focuses on the justice aspect: is it fair to create someone and then despise and reject him merely because of how he looks? What effect does this have on the person? Can we at least understand, if not completely approve of, the murderous trajectory he follows as a result? And the unspoken corollary: how should we judge the evil deeds of those who have suffered grievous injustice?

The opening scene has no counterpart in the book: we see a monster tumble out of a suspended translucent egg-like object and then wriggle and writhe on the stage for a good ten or fifteen minutes until he learns, all by himself, to use his limbs and walk. I saw this as a metaphor for a lot of things: evolution, physical maturity, emotional growth, intellectual achievement. You can view fragments of this in the trailer of the movie linked above. The entire production was a stunning achievement and kept popping into my head for a week or more after I saw it.

 Then a couple of days ago I watched what's been described as "the best movie that Danny Boyle never made", the opening ceremony of the 2012 Olympics. If you haven't, you should certainly set aside a couple of hours for it. It's been reviewed to death in the media so I won't repeat it here, you can read this nice review in The Guardian.

I'll just highlight two things. One is the sensibility - self-deprecating, light-hearted and inclusive. Lots of children singing, some in their pyjamas, a pastiche depicting the evolution of Britain's landscape from green meadows to ugly chimneys, a review of British music over the decades, some comedy from Mr Bean, a symphony orchestra, a skit of the Queen with James Bond, and a nod to the disabled, to immigrants, to just ordinary people (and a few ordinary cows and sheep too). It's been rightly described as "brilliantly messy" and "bonkers". A Tory MP tweeted his dislike of the multicultural nature of the show and this made me even happier than the negative reception of Slumdog in India! The slogan of the show was "This Is For Everybody" and in today's increasingly mean and narrowing world I found it very refreshing. Here is a nice article by someone else who did, too.

The second thing I liked, was a little story I read later. Given that rehearsals for this gigantic ceremony must have gone on for many many months, and involved tens of thousands of people, there were almost no leaks until virtually the last moment. How come a video of the rehearsal taken on someone's mobile phone didn't make it to YouTube? Frank Cottrell Boyce, the scriptwriter for the ceremony, had this to say:

`Danny could have asked for camera phones to be banned from the stadium or for people to sign confidentiality agreements. Instead he asked people nicely to save the surprise. "The volunteers are the best of us," he said. "This show belongs to them. This country belongs to them." '

I love this story and I wish that leaders of any sort learn this lesson. When you want people to support your efforts, place your trust in them first.

Kumar Gandharva - King of the Seasons


This article was written at the invitation of the Times of India for their Crest supplement, and a (slightly abbreviated) version appeared there in April 2012 around the time of Kumarji's birth anniversary. I'm posting the full version here, with some hyperlinks, for readers of my blog.

The great Marathi writer Pu.La. Deshpande once impishly remarked that we seem to think Classical music is so named because it is taught to us in class. In a similar vein he also complained that his job as a college professor was to create hatred for the Marathi language instead of a love for it! Both comments revealed his distaste for excessively formal approaches that end up distancing ordinary people. This dislike of formalism and orthodoxy was shared by his close friend, the singer Pandit Kumar Gandharva, who did not express his feelings in witty aphorisms but worked them into his music.

It is perhaps a little ironic that Kumarji is considered an intellectual of Hindustani Music. Of course he was, in the sense that he did not just perform but spent time thinking about music, forming his own ideas, discussing them with people and writing copious notes. Yet in a different and precise sense he was opposed to intellectualism. Neither in his compositions nor in his writings, nor in his body language during his performances, did he ever suggest that some specialised knowledge or ability was required in order to appreciate his music.

Quite the contrary. Kumarji’s legendary gestures – hands intertwined, then arms thrust out at an angle, then a single finger weaving an invisible spiral high above his head – invited the audience to trust their own feelings and access his music at an intuitive level. Just when his music seemed to be getting too abstract, he would often stop to make a joke about whatever he was singing. And once when questioned by critics about his inclusion of the note “pancham” in a composition in Raga Malkauns (from which it is supposed to be rigorously excluded), Kumarji is said to have responded “but it wanted to be there! What could I do?”

These were manifestations of his “people-friendly” ideology, according to which classical music should not be seen as something abstract or remote. Rather, it originates from the ordinary feelings of ordinary people, from emotions that arise out of daily experiences such as hearing the chirping of birds, meeting an old friend, waking up at dawn, preparing for a wedding or witnessing the changing of seasons. From this standpoint it was natural that he would consider raga-based classical music, folk music and bhajans as equally important parts of a single artistic vision. This remains one of the most enduring and unique aspects of his musical legacy.

Kumarji was a methodical person who worked out the broad structure of each performance in meticulous detail, though this in no way detracted from the spontaneity of his actual recitals. While most of his performances were in traditional formats, he enjoyed formulating thematic programmes to communicate specific concepts and created over a dozen of these. For his musically trained followers there were programmes highlighting a single raga or family of ragas, such as Kalyan ke Prakar, Bhairav ke Prakar and Goud Malhar Darshan. For other audiences and occasions he would perform entire programmes of bhajans based on the work of saint-poets like Surdas, Kabir, Meerabai, Tulsidas and Tukaram, or based on Marathi stage music or on “lighter” forms of classical music like thumri, tappa and tarana.

But the most audacious and unique of his programmes were those conceived around the seasons of the subcontinent: Geet Varsha, Geet Hemant and Geet Basant. Here his ideology found its richest expression. Bhajans, folk music from the Malwa region of Madhya Pradesh, and compositions in classical ragas, each had its own place in the programme and they would blend into each other seamlessly. Each piece would be designed to evoke an emotion or memory associated to that season, encompassing both natural occurrences like thunder and lightning, rainfall, cool breezes and bright moonlight, as well as human activities like farming, romance and religious festivals. A listener might initially be attracted to the programme through their own favourite type of music, but would end up appreciating that the differences among musical genres of our tradition are less important than the similarities. In this way Kumarji’s point would be proved.

Geet Varsha opens with a pre-monsoon sense of desperate thirst tinged with hopelessness, expressed through an alaap in Raga Marwa: “ghaam pare re”. But despair is short-lived as “nayo nayo meha” invokes the sighting of clouds for the first time. Once the rains seriously set in, the lyrics abound with references to swollen rivers, thunderstorms, songbirds and croaking frogs. Soon it’s time to settle down to the single “fully classical” segment of the programme, a half hour of Raga Miyan Malhar. This is followed by mid-monsoon romance conveyed in an elaborately fluid Pilu Khamaj tappa, “o dildaara aa jaa re”. The concluding piece is a muted and reflective composition in Raga Jaladhar Basant, beautifully capturing the moment when a spell of heavy rain has ended and we look around in silence at the boundless greenery. The Geet Basant programme (later replaced by Ritu Raj Mehfil) similarly captures the relief of the end of winter and moves rapidly into the wild revelry of Holi. The programme is rich with references to Krishna’s flirtations and the rituals of throwing colour, meeting friends, offering sweets, emptying one’s heart of anger. The philosophical bhajans of Kabir have no place here, but are supplanted with Surdas’s lyrical tales. And as always there is a classical core of exquisite original compositions in Bhoop, Bhimpalasi and Hameer, all set in madhya laya (medium tempo) which enhances the scope of formal development of a raga, but also makes it sound much like a song.

Though Kumarji was not the first in our culture to use seasons as a vehicle for art – after all, Kalidasa wrote Meghaduta over 16 centuries ago – he achieved the unique distinction of capturing the annual life-cycle of a people and a subcontinent in its own authentic musical language.

Higgs unmasked


Today was not like any other day. A historic announcement was made at CERN about the discovery of the Higgs boson, or something very much like it. I joined many others at TIFR in a lecture room to watch the live telecast of the proceedings. I won't review the science of this discovery here in any detail, instead I'd like to share some of the thoughts that went through my head as the lectures unfolded and then later on during the day.

The Higgs mechanism was discovered independently by six researchers in 1964 (only one of whom is called Higgs), based on a physical effect studied two years earlier by Anderson. So the fact that Prof. Higgs alone has become a household name is a shade unfair to the others. But then, you can't expect the press to get all breathless about a Brout-Englert-Higgs-Hagen-Guralnik-Kibble boson! And even if there had been a single discoverer, it's hard to imagine what the corresponding particle would have been called if that discoverer went by a name like Venkatachalapathy, or Klapdor-Kleingrothaus (the latter is a genuine German physicist). Let's just agree that it's good to have a short, snappy name if you want things named after you. Though it's less often highlighted, the other part of the term "Higgs boson" comes from the name of Satyendra Nath Bose whose work described the statistical behaviour of a generic class of particles called bosons. Again, I just couldn't help wondering what would have happened had this Bengali gentleman carried the surname Mukhopadhyay, or Raichaudhuri!

But enough of the flippant stuff. As Feynman put it very well, knowing the name of an object only tells us how human beings refer to it, but nothing about the object itself. What is important about the object under discussion today is that it's a key ingredient of a fairly elegant and simple mathematical theory, the Standard Model of particle physics, that accurately describes the behaviour of everything in the universe.

The last sentence is an over-simplification for essentially two reasons. One is that this theory only describes behaviour not involving the gravitational force. But this is fine as long as one stays away from immense gravitational forces such as those involving black holes or the early universe. Completing the theory to describe gravitational forces is the task of string theory, the field in which I work, but we can leave that story for another day. The second reason why it's an over-simplification is easier to appreciate. Knowing in principle the behaviour of every particle that makes up a jug of water, or a monkey, is almost useless to understand the behaviour of the composite object. This is why research in physics goes in two directions: one is to understand the fundamental constituents, the other is to understand how simple constituents are organised into larger objects that freeze at low temperatures, or bite when provoked, or exhibit some other type of complex behaviour.

Both directions are important. But in practice the "fundamental" and "complex" scientists rather tend to despise each other's preference. The "complex" scientist observes that finding and classifying fundamental particles - like the Higgs boson - is never going to answer questions like "when does water freeze?" or "why do materials superconduct?", let alone the trickiest one: "what is life?" Meanwhile the "fundamental" scientist feels that only by studying the most elementary objects can one aim to find elegant, universal and precise laws. Both sides are perfectly correct.

As someone who has tied his career to the "fundamental" or "reductionist" enterprise, I've seen its fortunes fluctuate quite a lot. It's been very popular through certain periods, while during other periods it has provoked irritation or even fury from scientists in the other camp. There are many possible reasons for this. One is the sheer audacity of the enterprise. Do we really think there can be a "theory of everything"? Another is the expense. Why should the nations of the world pool in a few billion Euros to answer esoteric questions about some particular elementary particle? Yet another is the fact that even the questions we raise, never mind the answers, are very hard for a person to understand without considerable prior knowledge of mathematics and quantum physics. And then there is the apparent indifference to social benefit. Will the Higgs boson cure cancer or mitigate climate change? Our community is seen to respond: "we do not care". Finally, there is the even higher level of grandiosity involved in claims like "particles are merely vibrational modes of strings" given that the strings would have a spatial size that is a million billion times smaller than things we know how to measure.

While all the questions raised above have (defensive) answers, sometimes it's best to let these questions just remain as they are and look at the other side of the picture. And I think today even the skeptics have had a close-up view of that other side, and hopefully have been moved by it. For around six decades, a global community of physicists - divided by everything else but united by their belief in the reductionist enterprise - have collaborated to uncover the secrets of nature. Some have done theoretical work, others experimental, yet others work in the middle ground between the two that's called "phenomenology". Over this period most of these people have never met each other, some have failed to even understand or accept each others' work, many have foolishly pitted theory against experiment (as though either one could ever be sufficient) and engaged in numerous other follies. But enough people gave of their best, and their best has proved good enough. The discipline of the scientific method, plus a collective dedication to the goal, washed out the conflicts and amplified the consensus. And today it's turned out that the whole thing holds together beautifully. It needn't have, but it did - and this for me is the best defence of the entire reductionist enterprise. It works.

So an absurd little particle, postulated for an apparently trifling reason, came to occupy centre stage in our quest and then held out for decades - but in the end it was unmasked by the sustained onslaught of a few thousand people (and, it has to be admitted, billions of Euros). The discovery of the Higgs boson might be the most sustained cooperative enterprise in the history of the human race!

And there's another grandiose statement calculated to annoy people...

One way ticket


A cousin recently mailed me an image file showing a painting of Henry VIII being beseeched by a woman on her knees, presumably one of the wives he sentenced to death. Below that is the logo of the London Underground and next to it the words: "A return trip to the Tower, and a single for my wife". It turns out this is a genuine ad that was used by the London Underground in 1977 and praised by a member of the House of Commons in these words: "It is that kind of imaginative approach which visitors to London find so interesting." On searching the web I also found a more recent ad, for an exhibition at the Tower of London titled: "Henry VIII: Dressed to Kill".

Of course old Henry did a lot of things both good and bad. He founded Trinity College and I dined for three months under his glowering portrait. But he had two of his six wives beheaded, along with a number of others. During the execution at the Tower of London, in 1541, of a certain Lady Salisbury, the axe failed to fall correctly and the half-beheaded lady sort of ran around the room for a while until they could get her head properly off, for which they had to hack her 11 more times. I was told this story in the room where it happened!

The British love these stories, as you can see from the way Henry VIII features in government-sponsored advertising. Mysteriously his life does not make British culture look barbaric -- while similar stories of barbarism in the history of the Orient tend to rub off on contemporary citizens, who still have to live with the image of being marauding Turks and Afghans for example.

An example is Timur the Lame. Wikipedia tells us he "stood forth in history as the supreme example of soulless and unproductive militarism. On the other hand, Timur is also recognized as a great patron of art and architecture, while he interacted with Muslim intellectuals such as Ibn Khaldun and Hafez." But ever since I've heard the name I've only associated it with barbarism (his sweeter side never came across) and I'm pretty sure the Turks don't make jokes about his violent methods. Nor do the Indians find his great-great-grandson Babar particularly funny...

I can't cure you: you must be mad


This comment is prompted by Sukratu's comment on my previous posting. He seems to have concluded from my blog that I suffered from a "psychosomatic illness". I'm not aware that this conclusion can be unambiguously drawn from what happened to me in recent times, but am prepared to consider that it's a possibility. In looking for some information on disorders or illnesses of this type, I came across several somewhat distinct classifications.

Lowest on the scale of respectability is the factitious disorder. This is diagnosed when "a person acts as if he or she has an illness by deliberately producing, feigning, or exaggerating symptoms". In short, the patient is faking the illness.

A somatoform disorder is a physical disorder that is entirely attributable to mental causes. One kind of behaviour that has recently been classified in this way is Munchausen Syndrome, in which "those affected feign disease, illness, or psychological trauma to draw attention or sympathy to themselves". This looks identical to the definition of factitious disorder above, but for one crucial word: "deliberately". In fact Munchausen used to be considered a factitious disorder and sufferers of this syndrome were contemptuously called "frequent flyers" (because they would be frequently in hospital) but after its reclassification as somatoform, they can take comfort that their problem is "not the result of conscious malingering ... sufferers perceive their plight as real" (from the Wikipedia link above).

Psychosomatic disorders  are higher on the scale of respectability. Wikipedia tells us that "Some physical diseases are believed to have a mental component derived from the stresses and strains of everyday living. This is the case, for example, of lower back pain and high blood pressure, which appear to be partly related to stresses in everyday life. Psychiatry has found it difficult until relatively recently to distinguish somatoform disorders, disorders in which mental factors are the sole cause of a physical illness, from psychosomatic disorders, disorders in which mental factors play a significant role in the development, expression, or resolution of a physical illness."

In other words, if its purely your fault then it's somatoform but if there's already a problem and your attitude is just making it worse, then it's psychosomatic. However it's important to point out that lay people usually understand "psychosomatic" to have the meaning given above to "somatoform", the latter word being quite unknown in common parlance.

Now what bothers me as a scientist is that the categories above are poorly defined, and classifying a patient into one of these categories is also an ill-posed problem. As the Medscape webpage on conversion disorder (a type of somatoform disorder) puts it, such disorders tend to be diagnosed when "symptoms of an organic medical disorder or disturbance in normal neurologic functioning exist that are not referable to an organic medical or neurologic cause". In other words, if we don't know what caused it then it must be mental in origin. Or as Wikipedia in a rare burst of humour puts it, "I can't cure you: you must be mad".

It's perfectly possible that things not currently understood by medical practitioners are not "psycho-" anything, but due to a very specific external cause. A prime example is the peptic ulcer. Long thought to be caused by emotional stress, it turned out to be in fact caused (in 70-90% of cases) by helicobacter pylori, a discovery that won a Nobel Prize in 2005 for Barry Marshall and Robin Warren. In a well-known story, once he was convinced of his theory Marshall actually swallowed the contents of a petri dish containing the bacterium and rapidly started to develop an ulcer. Since helicobacter is quite easily cured by an antibiotic, patients with ulcers are now treated with antibiotics (as was Marshall). Quite a change from what was done to me when I had signs of a developing ulcer in 1984. Then, doctors looked at me strangely and kept asking me to calm down and take it easy. They were pleased to notice that I was irritable (as anyone would be who had a constant nagging pain in the abdomen) since it confirmed the prevalent theory at the time. No one offered an antibiotic, since the result leading to the 2005 Nobel Prize was far in the future.

But the ulcer story doesn't end there. Recent studies still support the notion that "psychological factors do play a significant role" in the development of ulcers. The role is somewhat indirect, as helicobacter thrives in an acidic environment and stress can increase the production of stomach acid. In other words, to get an ulcer it helps to have both (i) helicobacter in your stomach, (ii) acid, possibly due to stress, in your stomach.

So if you scroll up you will see that ulcers remain "psychosomatic" by the definition I gave, namely that there's already a problem and your attitude has made it worse. But even this is rather facile. Emotional stress is not the only way to get excess acid in your stomach. You could be obliged to have irregular meals and/or irregular sleep times due to your job. Or just be starving due to poverty. All these will make you acidic and give any helicobacter inside you a pleasant environment in which to grow. Therefore the correct way to treat an ulcer is first to administer medication and second look into the causes of excess acidity if any.

This could also become the way to treat dystonia, irritable bowel syndrome and ulcerative colitis in future. The cause of none of these is known today,  but all have long carried the psychosomatic or even somatoform label. As an example, this research paper from 1950 finds ulcerative colitis to be closely associated with neurosis and this blog article recounts how it was related to schizophrenia! Today, however, genetic and environmental factors are being widely discussed in the context of UC, while both dystonia and IBS are being associated with problems in the basal ganglia of the brain.

So finally, is it your mind or your body or both? The best answer I can give is that it's always both. But telling the patient to calm down is never the first line of therapy.
