Can someone claim an extraordinary discovery instantly on exclusive basis of an incidental happening? An archetypal example is the legend that Isaac Newton arrived at the theory of gravitation after a falling apple bonked him on the head. As succinctly pointed in The Island, editorial “Docs, politicians and shamans” 18 December 2020; the ignorant tends to think Newton was an ordinary person who had that epoch-making aha moment solely because of the shock of the apple. History tells breakthroughs have not happened that way.

There is no evidence to the effect that an idea leading to a major discovery; a theory, cure for a disease, transformative invention or any other finding had originated abruptly in the mind of a discoverer wholly as a result of an extraneous real-world event. Similarly, there exists no convincing proof that that telepathic invention of paranormal agents has provided correct disclosures or valid solutions to real problems.

The history of science points to the conclusion that the anecdote of the falling apple and Isaac Newton has been decorated by story-tellers and perhaps by Newton himself. Newton arrived at the theory of gravitation after years of unprecedented deep contemplation and hard work.

 

Isaac Newton and Theory of Gravitation

Isaac Newton born prematurely on Christmas day in 1642 was a physically weak child. His father died a few months earlier, when the widowed mother got married again, his grandmother adopted him. He was sent to a grammar school for few years and schooling discontinued to coach him as a farmer. Newton hated farming, quarreled with his stepfather devoting time to read and make mechanical gadgetries. His schoolmaster advised his guardians to send the boy to school again, saying he is talented. Newton ranked topmost in class, has said, he worked hard to revenge, the classmates who bullied him.

Newton was admitted to Trinity College, Cambridge, in 1661. His mentor there was Isaac Barrow – the Lucasian Professor of Mathematics. Barrow introduced the frontiers of mathematics at the time to Newton, knowing his capability. In 1665, when the College was closed because of the plague, Newton returned to his village home in Lancashire, leisurely continuing studies and exploring almost all contemporary problems in mathematics and physics.

Newton returned to Cambridge in 1666 and continued to interact with Barrow. In 1669 Barrow tendered his resignation in favor of his student, recommending Newton to the Chair he occupied – an incident unheard in the history of academia.

 

Astronomer Edmond Halley visits Cambridge to meet Newton: The most consequential discussion in world’s history

Discussions, whether secretive or not often lead to consequence of utmost importance. Wars, revolutions, declarations of peace and political upheavals would have been catalyzed that way.

A discourse between two individuals that changed the world forever was the meeting of the astronomer Edmond Halley and Isaac Newton in Cambridge in 1684. That discussion resulted in the publication of Principia Mathematica-the monumental work of Newton which transformed the world.

Newton, holding a prestigious chair in Cambridg, gained acclaim as an extraordinarily clever physicist and mathematician. Nevertheless, he feared the criticism of senior peers. Notably, the polymath genius Robert Hooke and did not publish things that might lead to controversy. Hooke, contemporaneously working on theory of gravitation, wrote to Newton in 1679, expressing his views on the subject. Newton never replied! Later as an influential office-bearer of the Royal Society, Hook prompted the astronomer Edmund Halley to consult Newton.

Edmond Halley keen to understand why the comet subsequently named after him reappeared every 75 years, visited Cambridge and met Newton in August 1684. Newton explained he had already solved the problem of planetary motion. According to his theory of gravitation, objects move around the sun in elliptic orbits. Halley persuaded Newton to publish his work, agreeing to meet the cost of printing.

The first edition of Newton’s Principia was launched in 1687, awakening the whole world – the birth of the age reason.

Robert Hooke reacted furiously, accusing Newton of plagiarism, referring to his 1679 communication. The acrimonious rivalry between Hooke and Newton which started in the late 1670s continued until former’s death 1703. Newton’s other major work ‘Opticks,’ which he postponed publication, because of an argument with Hooke at the Royal Societyin 1672 was sent to printers immediately after Hooke’s demise!

 

Newton’s arch-rival Robert Hooke wrote the Preface to Robert Knox’s Book on Sri Lanka

Unlike Newton, Robert Hooke had been a social being. He mixed with people of all ranks and wakes of life in coffee houses. Through persons encountered, Hooke got acquainted with Robert Knox, who had just returned to England after captivity in Sri Lanka and was inquisitive to learn his experience in Sri Lanka. Hooke exhibited Talipat leaves Knox carried to England at the Royal Society. He tested cannabis brought from Sri Lanka by Knox and gave a talk at the Royal Society in presence of the science stalwarts; Robert Boyle, Christopher Wren and Edmond Halley. He told society this intoxicating agent referred to as Cansa or Bangha in Ceylon; takes away memory and understanding for a time. Hook was probably first to examine psychoactive drugs scientifically.

Robert Hooke wrote the preface to the Robert Knox’s book “Historical Relations of the Island of Ceylon and the edited the text. In preface signed 1st August 1681, discusses the virtues of publishing; and state “There are but few who, though they know much, can yet be persuaded they know anything worth communicating and because the things are common and well known to them, are apt to think them so to rest of mankind; this prejudice had done much mischief “. He also commented that some avoid communicating because of the fear to be in print, while others delay it. Presumably, what Hook attempts to insinuate is: had Newton published his work on gravitation much earlier; the bitter controversy with him would not have arisen.

 

Story of the falling apple

Newton, in any of his writings, has not mentioned that a falling apple hinted him the law of gravitation. The story of the apple surfaced in 1752, a quarter of a century after Newton’s death. According to a biography of Newton written by his close friend William Stukely in 1752; he had visited Newton in April 1726 to interview him. While having tea in the garden, Newton pointing to apple trees there, said that he fathomed the concept of gravitational attraction 60 years ago, noticing an apple detaching from a tree and falling. The authenticity of this story as written by William Stukely remains controversial. Later the story was made sensational by saying, the apple bonked on Newton’s head.

Apart from Newton’s work, the idea of gravitational attraction had been around as evident from the published work of Robert Hook. Strangely in the same year Newton was said to have been inspired by the falling apple, Hook in a communication to the Royal Society had stated that planetary bodies mutually attract each other via gravitation. Therefore, the decoration of the apple story could have been a gimmick to cement the standing that Newton was the first to consider gravity as attraction between two objects – not Hooke.

What Newton really did was far more challenging. He demonstrated mathematically that the force attracting the apple to the earth, also keep the moon revolving around the earth and planets around the sun. Even if Robert Hook had been the first to conceive the idea of gravitational attraction, the originality of the monumental work of Newton would not be blemished. Unfortunately, Newton failed to realize this, and when he became the President of the Royal Society he did everything possible to eclipse Hooke.

Newton feared criticism, but suppressed and attacked his adversaries. Oppositely, many feared Newton because of his unmatched intellect. Newton was elected to British Parliament honouring his most distinctive social status. He spoke only once. When he raised the hand, the dumbfounded house feared, what an issue this great man is going to raise. But Newton said; please close the adjoining window, chilly wind is blowing!

Many men and women have the potential of reaching the pinnacle of a genius. It is by study, dedication and desire to find the truth and not by unfounded declarations, exaggerations or ranks they strive to achieve.

Is power devolution under JVP-NPP a political daydream?

Published

on

Former President Chandrika Kumaratunga

The JVP General Secretary Tilvin Silva’s recent remarks at a news conference in Jaffna where he ruled out the possibility of holding provincial council elections this year has been widely reported and widely criticized. About the same time there was another media event in Jaffna that went largely unnoticed and unreported outside Jaffna. What was said at the second media event may carry far more political implications than Tilvin Silva’s election timing talk. A veteran Tamil political participant made the startling yet not implausible statement that the prospect of having political devolution under the JVP-NPP government is becoming “a daydream”. The statement was made by Dr. K. Vigneswaran, who served as Provincial Secretary to the only North-East Provincial Council Government that was elected under the auspices of the Thirteenth Amendment.

Dr. Vigneswaran is a Professional Civil Engineer who studied at Royal College, graduated with First Class Honours in Engineering in 1964, and went on to complete a pioneering PhD at the university of Waterloo, Canada, applying the finite element method (FEM) in the field of Geotechnical Engineering. His engineering career has always been at the Irrigation Department where he rose to a Deputy Director. That was when the department was in its golden years, and Vigneswaran was known for his technical mentorship, meticulous administrative skills, and for knowing the fine print of everything. While at the Irrigation Department, Vigneswaran married Ramya de Silva, a fellow irrigation Engineer. After 1983, Vigneswaran became a fulltime political activist and a powerful resource in Tamil politics, but with unwavering commitment to nonviolence, democracy and federalism. The family moved first to India and then Canada, and Vigneswaran has been shuttling between Canada and Sri Lanka.

Devolution: Tortuous Trajectory

Since 1987, the Indo-Sri Lanka Agreement, and the 13th Amendment, Vigneswaran has been a permanent fixture in all the politics and institutional dynamic of implementing 13A and establishing provincial councils. He served as Secretary to the only elected Provincial Government for the Northern and Eastern Provinces. After 1994 and the election of Chandrika Kumaratunga as President, Vigneswaran became a key participant in all the civil society efforts and government initiatives to restore the PCs and implement 13A, both during the Kumaratunga presidency and the succeeding administrations of Mahinda Rajapaksa and the Sirisena-Wickremesinghe duo.

Devolution efforts stalled after the election of Gotabaya Rajapaksa, who in so many words declared that he had no time for 13A or PCs in his presidential agenda, whatever it was. Only that his whole agenda turned out to be a wholesale disaster for the country. Already by then, all the nine Provincial Councils had fallen into abeyance with the cancellation of the 1988 PC elections by the Sirisena-Wickremesinghe duo, with the TNA standing by. The abeyance continues under the JVP-NPP government with no apparent end in sight after Tilvin de Silva’s statement in Jaffna.

I say all this to provide the proper context for Vigneswaran’s statement in Jaffna that the prospects for power devolution under the JVP-NPP government are becoming a political daydream. He said something else as well: that of all the government leaders he has encountered over the years, the only leader who has been genuinely sincere about power devolution is former President Chandrika Kumaratunga, and no one else. I am constrained to add that the insincere category would include Ranil Wickremesinghe, who for all his handsome promises, never matched any of them with experiential sincerity. The present JVP-NPP government still has time to show that they are not an insincere lot.

It is not my purpose to agree with or question Dr. Vigneswaran’s assertions, but to use them as cue and context to comment on the widening mismatch between the JVP-NPP government’s promises and its practices on the matter of power devolution and the restoration of the PC system. With a stalling economy, rising prices and external shocks, it is obvious that the government has all the economic matters to worry about, but that does not mean that it can ignore all the other government responsibilities. No government is put in power to solve a single problem or address a single issue. It is in the nature of governments to deal with multiple problems with varying priorities. Otherwise you could have a single cabinet minister to deal with one problem at a time. That is never going to be the case.

The economy is of course the top of mind priority for the government even as it is a top of mind concern for the people. Even on the economic front, the government is holding steady but is showing little progress. And there are other government initiatives where political accountability will call for answers: to wit, the catchall Clean Sri Lanka programme, ambitious educational reforms, contentious energy sector reforms and, yes, power devolution as well as the overpromised constitutional reforms. Not to mention the sprawling unforced errors over substandard coal imports, foreign exchange fraud, and the chronic neglect of developing the renewable energy sector. Correcting these fields of errors may require a separate ministry for each.

Devolution: Daydream or Deliverable

On the PC system and constitutional reform, there has been scant progress in spite of handsome promises. On both, the government is inadvertently deepening the holes that it had dug itself into through indifference, inaction or procrastination, or all of them and more. In the matter of devolution and provincial councils, the government can simply defuse the situation by directing the Election Commission to conduct elections at the earliest opportunity that is logistically possible. Making his statement in Jaffna, Mr. Tilvin Silva alluded to funding shortfall and legal complications as reasons for the necessity to postpone PC elections until next year. Neither reason holds water.

The funding question would seem to have been put to rest by the statement of Health Minister and Cabinet Spokesman Nalinda Jayatissa, presumably reflecting cabinet consensus, that there are no funding issues and if needed additional funds could be arranged through supplementary allocations. It is also disingenuous to cite legal complications as a reason. The so called legal complications arose because of the collective stupidity of the Sirisena-Wickremesinghe parliament that included the then miniscule NPP and the politically-lost TNA. The JVP-NPP has now ballooned from a handful MPs to a two-thirds majority and it can expedite any legislation that it wants to enable the PC elections to be held without delays.

Alternatively, the elections can be held under the old arrangement of proportional representation with assurance by political parties to honour their commitment to fielding more female candidates. Already at a gathering of all political parties, including the NPP (but not the JVP), and civil society groups, convened by People’s Action For Free & Fair Elections (PAFFREL), the political parties jointly committed to a 25% quota for women and youth under the old electoral system. The ongoing parliamentary committee exercise studying the legal matter, headed by the overstretched Foreign Minister Vijitha Herath, is also an unnecessary red herring. The Election Commission is ready to go under whatever law or electoral system that is before it. So, there is no reason to hide behind legal complications to further delay the PC elections.

Somewhat amusingly, Public and Parliamentary Affairs Minister Ananda Wijepala has trotted out the argument that the NPP government has already conducted two nationwide elections during the one and a half years it has been in office, and that unlike the Ranil Wickremesinghe government the JVP-NPP is not in the business “to delay elections for our personal benefit” – whatever that means. Unfortunately, the good minister is missing the point. The question is not how many elections can the JVP-NPP hold in how many years, but how many years do people in the provinces have to wait before they vote in another provincial election? How many more years? That really is the question.

We know the current situation in the provinces. There are provincial governments but no elected provincial councils. The government administration in every province is being run by the President of the Republic through his handpicked governors and unelected government officials. This is a travesty of democracy and the euthanizing of the PC system. Already under 13A, the office of the provincial governors has been constitutionally and legally compared to the office of the Governors of old Ceylon who represented the monarch in what was then a crown colony. The irony is that a JVP-NPP President may have inadvertently positioned himself as the monarch of all he provincially surveys, courtesy of the Thirteenth Amendment!

The JVP was in the forefront of the litigation that caused the demerger of the Northern and Eastern Provinces. If Dr. Vigneswaran’s assertion were to prove correct, a potential dissolution of the provincial system under the JVP-NPP government would be the consummation of the JVP’s original opposition to the introduction of the provincial council system itself. The whole system may not be eradicated, but it could be devoured of its democratic essence while preserving the administrative shell as the medium for the country’s president to overreach into the provinces. That would be worse than a daydream, a real nightmare.

Rewiring Brain: Meditation to Break the Cycle of Craving

Published

on

“Craving begets sorrow, craving begets fear. For him who is free from craving there is no sorrow; how can there be fear for him,” Dhammapada verse 216 states. The mental factor craving, Tanha in Pali, is central to Buddhist Teaching, as its ultimate goal is the cessation or extinction of it—tanhakkhaya. Even though Tanha is translated as craving here, it can sometimes mislead modern readers into thinking tanha only refers to extreme or physical addictions. Just as with any Pali term, it has broad meanings. Venerable Walpola Rahula describes it as “thirst” or unceasing wanting, one of the deep-rooted proclivities or latent tendencies (anusaya) of life (Rahula 1959), without which life as we know would not exist.

Even though the Buddha recognized this natural phenomenon two and a half millennia ago, it was only in the late 20th century that science took note of it and gave it a captivating term—the Hedonic Treadmill. The advantage of this empirical investigation to us Buddhists is that it provides a way to gain penetrative, experiential comprehension (anubodha) of this concept using the vernacular of this technology-savvy age—an alternative to struggling with the language of a bygone era.

These investigations have revealed that there are no hard-to-comprehend metaphysical or mysterious elements involved with this phenomenon; it is a biochemical process fundamental to sustaining life. What is more, an effort to grasp this concept would be well within the goals of Vipassana meditation described in the Sutta Pitaka, incorporating the four elements of investigation: body (kayanupassana), sensations (vedananupassana), mind (chittanupassana), and natural laws (dhammanupassana).

Vipassana and modern science

Vipassana meditation is an in-depth exploration of how humans perceive the world, gain knowledge, and interact with themselves and the environment. Knowing this with wisdom allows one to lead a harmonious way of life (samadhi), a condition conducive to curbing the “thirst” and achieving the Buddhist ideal. The goal of modern science is also to investigate life, but humanity has often used that knowledge to increase material wealth and comfort, providing only lip service to spirituality on the fringe.

An attitude that tends to ignore the consequences of wanting more and more – thirst, potentially endangering the planet. However, that does not prevent us from using scientific information as and aid or a tool to grasp Buddhist concepts. The scientific method bears parallels to the Buddhist approach: it is based on causality (paticcasamuppada), empirical verification (ehipassiko), systematic observation (meditation), and rejecting dogma and beliefs. The primary difference is simply the vocabulary used.

The process of perception: five aggregates

Our five external sense organs receive data (vedana) containing information on the environment: Eyes: receive light, Ears: receive sound, Skin: senses physical contact and temperature, Nose & Tongue: sense chemical properties of substances. The data received by the sense organs is transmitted to the brain, where it is registered as neural networks (sanna). Neural networks, which are interconnected groups of nerve cells (neurons) can be viewed as mind-readable QR codes.

The activity of the brain, or mind (mano), processes this data and converts them into actionable information (sankhara). Modern neuroscience and psychology have made great advances in understanding these processes at the molecular level. This process allows the individual to become aware of their environment, build an autobiographical memory or the notion of a self (atta), and take actions to protect and perpetuate life.

The Pali term vinnana refers to the collection of information committed to memory. Translating vinnana as “consciousness” can be confusing, as the latter often refers to all brain activities. All physical phenomena that sense organs encounter and the mental constructs (sankhara) are referred to as Rupa. This activity of mind forms the basis of all knowledge, representing the entire world as perceived by the individual. This process is what the Teaching refers to as the Five Aggregates (pancakkhanda). The critical takeaway is that the world we perceive is merely a mental construct. While an objective world exists, our sense organs have limitations in seeing it—a fact easily realized through the hundreds of illusions used for entertainment.

Evolution and emotion

The evolutionary purpose of this data processing mechanism is to enable living beings to respond to environmental factors for survival. The psychological and physiological state that arises prior to acting is called emotion. Primarily, emotions can be of three kinds: desire (loba) – seeing a new phone causes an urge to buy it, even though the current one works fine; aversion (dosha) – encountering a vicious dog triggers a “fight or flight” response; delusion (moha) or illusion – an unanswered message to a loved one triggers worry or speculation. Thus, tanha or thirst represents how we connect to the world in its entirety; it can be desire, aversion, and delusion, not merely simple greed. Consequently, these are natural phenomena beyond our immediate control, which are intended to sustain life. In other words, emotions are the forerunner to volitions or intentions, which the Teaching defines as kamma.

The biochemistry of craving

Emotions result from the interaction between the nervous system and biochemicals known as neurotransmitters and neuromodulators (e.g., dopamine, serotonin, epinephrine, GABA, glutamate, acetylcholine, and endorphins). Just as the Buddha’s simile of two bundles of bamboo supporting each other describes, these two processes are interdependent and co-arising. Every thought or emotional state corresponds to patterns of neural firing. When neurons fire, they release these chemicals into synapses, influencing how one feels and acts. This release perturbs the body’s normal balance, or homeostasis. Once an action is complete, these chemicals are reabsorbed, and the body returns to its baseline.

Return to baseline is essential for survival. For example, if we stay satisfied with just one meal forever, we could not sustain life. Nature has developed another mechanism to prevent us from being satisfied – we also habituate. In the case of dopamine, the brain adapts by reducing the response to the same stimulus. To get the same level of satisfaction with repeated experiences, the amounts of neurotransmitters needed keeps increasing. This leads to the cycle of craving and dissatisfaction—the Hedonic Treadmill. You “run” toward happiness on the treadmill, but it does not take you anywhere, leaving you in the same emotionally unsatisfactory state, wanting more and more.

Breaking the cycle

This explains why achievements and possessions do not bring permanent happiness, and lead to a cycle of struggle, addiction, crime, and other ills of society. For Buddhists, it also explains why we cling to meaningless rituals. The Dhamma captured this complex phenomenon in the Four Noble Truths: pleasant experiences are impermanent (anicca), leading to grasping (tanha) and unsatisfactoriness (dukkha). The remedy is the Eightfold Path that involves wisdom (panna), conduct (sila), and harmony (samadhi).

Neuroplasticity and the point of liberation

While we cannot stop the sense organs from receiving stimulation (vedana) and sending them to brain, the mind can be developed to prevent vedana from leading to tanha. This is the “point of liberation,” the seventh link in the paticcasamuppada formula. We may not have free will, but we have ‘Free Won’t’ or the ability to say no to the natural tendency to act upon stimuli. We can rewire our neural connections to do so. This ability can be cultivated by practice and repetition, and neuroscience refers to it as neuroplasticity—the brain’s ability to change with experience.

The natural tendency of the brain is to strengthen frequently used neural networks while weakening and eliminating lesser used networks and building new ones as needed. This is known as neural plasticity or rewiring the brain. As described in the Eight-fold Path, the way to weaken and eliminate dopamine-driven neural networks includes three aspects. First, the process leading to thirst must be understood. One must engage in sila – activities and thoughts that cultivate Metta: loving-kindness and goodwill, Karuna: compassion, Mudita: appreciative joy, and Upekkha: equanimity, emotional stability, calmness, and evenness of mind in the face of gain and loss, praise and blame, fame and disrepute, pleasure, and pain. That must be done with wisdom, ritualistic behavior does not strengthen the correct neural networks. These activities promote a “cocktail” of oxytocin, serotonin, and GABA, subduing the role of dopamine and helping us step off the Hedonic Treadmill. This leads to a tranquil state of mind and a harmonious existence – samadhi. Again, it is an interdependent, co-arising process that improves upon repetition. Using mind altering substances hijacks this process, thus the need for adhering to the Fifth Precept.

The goal of Vipassana is to understand this process and train the mind to say “no” to tanha. It is not just about sitting on a mat; it requires developing a lifestyle that maintains homeostasis or harmony, samadhi, at every moment. Pali term bhavana means the development of wisdom and insight. In modern vernacular – rewiring brain. This model must be assessed for its efficacy by the individual and realize the benefits by themselves –ehipassiko; knowledge without practice does not work. According to what the Buddha taught, that is the path to cessation or extinction of craving – tanhakkhaya, the supreme goal.
