Use of colours in pre-historic era

Humans have been long fascinated by colour, which has played a significant role since the beginning of human civilization. Ancient people had painted caves even before they settled in houses. Cave paintings were created during the stone age from 10,000 to 40,000 years ago. Primitive artists used natural materials available to them to mark their territory, beautify their surroundings, and tell their stories. For thousands of years, paints were handmade from ground mineral-based pigments. Ochre, a natural pigment which comes in shades of red, yellow, orange and brown, was the first pigment used by humans, in the Middle Stone Age of Africa. Ochre, also called hematite, is found all over the world and has been used by nearly every prehistoric culture, whether as paint on caves and building walls, for staining of pottery or other types of artifacts, or as part of a burial ritual or body painting.

Man’s irresistible desire to create pigments was not without untoward consequences. For instance, in 1,775, Carl Wilhelm Scheele, a Swedish chemist, invented a bright green pigment, but it was laced with the deadly poisonous chemical arsenic; it was cheap to produce, but dangerous for artists and patrons alike. However, the French emperor Napoleon Bonaparte was so fascinated by and passionate about this colour, he wanted his bedroom wallpaper painted with Scheele’s Green. Historians believe that the green pigment used in the wallpaper caused his untimely death in 1821 at the age of 51 due to cancer. By the end of the 19th century, Paris Green—a mixture of copper and arsenic—replaced Scheele’s Green as a more durable alternative, enabling Claude Monet, Paul Cézanne, and Pierre-Auguste Renoir to create vivid, emerald landscapes. It is also toxic, and thus has also been used as a rodenticide and insecticide. The blindness which Monet subsequently succumbed to may have been due to the toxicity of Paris Green, which was banned in the 1960s.

The Egyptians artists added binders such as eggs, resins and beeswax to pigments so that the paint would adhere to plaster and began painting on it. Hence, Egyptian tombs made of limestone were covered with plaster that was painted using six colours: charcoal black, red ochre, yellow orpiment, brown ochre, blue azurite, and green malachite. Natural mineral pigments were dug from the earth and shaped into sticks that were used as chalks by artists including Leonardo da Vinci, Michelangelo, and Rembrandt. Dyes made from plants were also used in artwork in the Mediterranean region. By the mid-nineteenth-century, watercolors became available for sale to the public. Since the 1940s, technological advances have produced synthetic pigments and chemical processes for paint making which greatly contributed to expanding the once mineral-based limited colour palette to all the colours of the rainbow. Since then, colour-based industries have grown progressively in the world and the worth of the paint and coatings industry and of colour cosmetics industries in 2023 amounted to around $ 180 billion and $ 80 billion, respectively.

Physics of colour and vision

In the 1660s, English physicist and mathematician, Isaac Newton, demonstrated that clear white light was composed of seven visible colours. Johann Wolfgang von Goethe in 1810 published his treatise on the nature, function, and psychology of colours titled “Theory of Colours”. One of his most radical points was a refutation of Newton’s ideas about the colour spectrum, suggesting that darkness is an active ingredient rather than the mere passive absence of light. Though his work was dismissed by a large segment of the scientific community, it remained of intense interest to a cohort of prominent philosophers and physicists, including Arthur Schopenhauer, Kurt Gödel, and Ludwig Wittgenstein.

Colour springs from the alchemy of light and perception. Light, an ethereal wave of electromagnetic radiation, spans a spectrum visible to human eyes from approximately 380 to 750 nanometers. As light touches an object, it may be reflected, absorbed, or transmitted, with the reflected wavelengths crafting the hue perceived by the eye. This interaction is interpreted by the brain, transforming raw light into the rich palette of the world around us.

The human eye, a wondrous instrument, houses three types of photoreceptor cells known as cones, each attuned to different wavelengths of light:

S Cones: Sensitive to short wavelengths, peaking around 420 nm, endowing us with the perception of blue.

M Cones: Responsive to medium wavelengths, peaking around 534 nm, allowing us to see green.

L Cones: Tuned to long wavelengths, peaking around 564 nm, revealing the red hues.

Human beings can only see the colours that these receptors can receive. Together, these cones create a symphony of signals that the brain harmonises into the countless colours we perceive, enabling us to distinguish millions of shades.

Nature’s creatures possess a diversity of vision, often surpassing human capabilities. Birds and insects, for instance, enjoy a tetrachromatic[DC1] vision (having four types of cone cells in the eye to perceive colour), with an additional type of cone sensitive to ultraviolet (UV) light, unveiling a hidden spectrum invisible to human eyes. Many bird species use UV signals for mating, navigation, and foraging.

Colours are ‘illusions’

People are quite interested in and passionate about colours; thus, they generally make an initial judgment about a product, person, or environment within 90 seconds, and a significant proportion of this assessment, i.e. 60-90%, is based on colour. This shows how strong the influence of colour on perception and decision-making is. Despite this extraordinary experience of colour perception, all colours are ‘illusions’ in the sense that they do not belong to objects independently of how these are perceived. Neither objects nor lights are coloured ‘in themselves’, but are seen as coloured as a result of neural processes and perceptual mechanisms. In fact, the physical properties of colours are different from the way colours are perceived. For example, take a yellow sunflower; it absorbs the blue, red and other colour energy waves, and then reflects back wavelengths that appear yellow. The colour receptors in our eyes then translate the flower’s wavelength into its colour and send that to our brain.

Blue colours in animals are not caused by chemical pigments, but rather by physics and the way light bounces off a surface. Blue-winged butterflies have layered nanostructures on their wing scales that manipulate light layers, cancelling out certain colours and projecting the fluorescent blue colour that we see; thus, they are called structural colours. Another classic example of structural coloration is the peacock’s feather. The microscopic structures in the feathers manipulate light to produce brilliant blues and greens that shift and change as the viewing angle alters. Thus, blue butterflies, roses, and peacocks aren’t actually blue and our eyes have duped us (Fig. 1).

Effects of colour on human behaviour and wellbeing

People have long understood the power of colour over moods and well-being. Colour was used in ancient Egypt, China, and Greece to evoke emotions, aid in spiritual practices, and treat a variety of conditions. Many ancient civilizations, such as the Egyptians and Chinese, embraced the belief that colours possessed healing properties and could be harnessed for therapeutic purposes. This practice, known as chromotherapy, involved the use of specific hues to treat various ailments and promote overall well-being.

Colour is a multidimensional concept which goes beyond visual appeal and aesthetic beauty. It encompasses physical, psychological, cultural, symbolic, artistic, aesthetic and scientific dimensions, including physiological. The aesthetic beauty of colour has added a mesmerizing and exciting tapestry to nature and it is inconceivable to imagine a world without colour. Leigh Hunt (1784–1859), prolific English poet and journalist, said “Colours are the smiles of nature”.

Colour can affect humans in manifold ways ranging from psychological, physiological, cognitive to emotional, behavioural, healing etc., thereby having a profound influence on their mood, creativity, productivity, health and happiness. In addition, it has a remarkable power not only to heal, rejuvenate and inspire, but also to instill a sense of peace and harmony in us. Colour is also a powerful means of communication and a defining aspect of human experience, influencing our perceptions and preferences, and interactions with the world. Therefore, extensive studies have been carried out on those aspects which have led to the emergence of disciplines such as Colour Psychology, Colour Chemistry, Colour Therapy and Visual Ergonomics. Colour can potentially be a powerful source of inspiration, delight, tranquility and solace when used in the right manner for the right place for the right purpose.

However, people generally apply colours purely based on the visual and aesthetic appeal, without a proper understanding of the profound impact that colour can have on people – their performance, experience and wellbeing. Therefore, the use of the right colour for a given place is crucially important in order to provide a more relaxed, congenial and harmonious living environment which goes beyond the aesthetic appeal. Here, it is important to explore the world of colour psychology without diving into technicalities

The colours you choose for your walls, furniture, and the decorations of your bedroom can influence your mood. A bedroom painted in calming tones, e.g. in light blue, might help you to unwind, and create a feeling of serenity. It is not recommended to paint the bedrooms in dark shades of blue as it could interfere with sleep. Similarly, the blue light emitted by electronic screens could produce a similar effect. Therefore, it is not advisable to work on the computer or watch film on electronic screens for long hours prior to retiring to bed. Because the blue light gives the impression to the brain that it is daytime, the body stops releasing the sleep hormone Melatonin. On the other hand, light shades of amber may promote the release of Melatonin helping us to wind down and prepare for sleep in nature’s way.

Feeling relaxed

As blue light causes people to feel relaxed, it has led countries to add blue street lights in order to decrease suicide rates. In 2000, the city of Glasgow installed blue street lighting in certain neighborhoods and subsequently reported the anecdotal finding of reduced crime in these areas. A railroad company in Japan installed blue lighting on its stations in October 2009 in an effort to reduce the number of rail suicide attempts (Fig. 2). Blue is often associated with calmness and serenity and is not naturally associated with food; hence, it can make food appear less appetizing and appealing and reduce the desire to eat. Therefore, blue is generally considered an appetite suppressant and eating off a blue plate could help to reduce overweight and obesity.

Walls of cafés are generally painted in warm, earthy tones like brown or terracotta which evoke a sense of comfort and homeliness. It helps the customers to settle in with a cup of coffee and a good book to spend some relaxing and rewarding time in a congenial ambience. On the other hand, some fast-food chains use red and yellow in their logos and external and internal walls in order to create a vibrant and exciting environment. It not only attracts attention, promotes quick decision making and creates a sense of excitement and urgency, but also stimulates appetite and encourages lively discussion. Though such colours attract both children and adults to fast-food restaurants, they may not wish to stay long in such an ambience after partaking of food, unlike in a coffee shop. Similarly, a kitchen with lively colours could energize you during meal preparation. (Figure 2)

Even when designing websites, careful attention is paid not only to aesthetics, but to emotions that need to be evoked. When a company designs a new website, it carefully selects colours with this in mind. They might use blue for trust, green for growth, and orange for enthusiasm, creating a website that feels inviting and reliable while encouraging action. Architect William Ludlow advocated pale pastel blues and greens in hospitals for therapeutic purposes. The walls of hospitals are often painted in soft, calming colours like pale green or light blue which help to reduce stress and create a healing environment.

Colour can enhance or impair learning, morale, performance and the behaviour of students. It can affect students’ attention span, and perception of time. Visual stimulation rewires the brain, making stronger connections while fostering visual thinking, problem solving and creativity. It has been shown that the cold-coloured walls, such as blue and green, produced the highest levels of relaxation and pleasure, while the warm-colored walls such as yellow and red had the better attention and learning performance. And the white-walled classroom had the lowest subjective evaluation and the worst learning performance. Classrooms when painted with bright yellow — the colour of happiness and optimism – spark creativity and enthusiasm and makes learning more joyful. That’s why some educational spaces use yellow in order to foster a lively and energetic environment. School buses are generally painted yellow the world over for safety and visibility. Yellow colour is in the middle of the visible spectrum so that it strikes the cones (photoreceptors) of the eyes from both sides equally. That makes it almost impossible for anyone to miss a school bus even when it’s in one’s peripheral vision or under poor day light conditions or in bad weather.

Fitness spaces

Exercise rooms and fitness spaces are generally painted in bright orange which exudes energy, motivation and vitality, encouraging movement and activity. It helps to keep the energy high and spirits lifted. Studies have shown that red causes a significantly greater response in heart rate, respiration, brain wave activity, and other nervous system functions than green or blue. In addition, red decreases the perceived size of rooms and space and prompts a sense of warmth. Lush greenery in a park or a natural habitat has a refreshing and rejuvenating effect, creating a sense of harmony and tranquility. Besides, the choice of colour of clothing reflects and affects your mood and if you are feeling upbeat and confident, you might pick a vibrant red shirt or dress. On the other hand, if you seek comfort and tranquility, you may settle for soothing shades of blue, green, etc.

Choice of colour for prisons is of prime importance as it affects the mood of inmates. When colour is used properly in prisons and jails, it can lessen overall tension and conflicts and make the places more comfortable for the inmates to live and work in. Based on the research carried out, bright colours are recommended in the prison, with green and blue colours being the best rated because people perceive them as soothing, stimulating, pleasant and safe. Yellow is also acceptable because the prisoners perceive it as a bright and cheerful colour. Painting the walls of the room with soft shades of yellow and green (kiwi color) was seen by the prisoners as “refreshing”. In all these cases, colour psychology is at play.

Therefore, colours play a significant role in shaping how we feel and behave; thus, they are not just pretty hues, but are the emotions painted onto the canvas of our lives. Hence, colour psychology is like a storyteller that sets the mood and tone of a space, a product, or even a piece of clothing. It’s the silent language that whispers to our emotions, shaping our experiences without us even realizing it. However, these associations between colours and emotions are not universal, but are influenced by cultural, historical, and personal factors. Understanding colour psychology can help individuals and businesses harness the power of colour to evoke specific emotions and convey messages effectively. Whether in branding, interior design, fashion, or art, colour plays a central role in shaping our perceptions and experiences. It’s a fascinating aspect of our world that continues to intrigue and inspire creativity in various fields.

Further information in this regard is found in the book titled “The Power of Colour: Enhancing Human Wellbeing and Unleashing Human Potential” edited by Ranjith Senaratne and Raj Somadeva. It emanated from a conference conducted by the Sri Lanka Association for the Advancement of Science and includes contributions from a multidisciplinary team comprising artists, architects, engineers, biologists, environmentalists, psychiatrists, musicians and scientists.

Concluding remarks

Though the manifold effects of colour on humans have been recognized from time immemorial, there is very little appreciation and understanding of those effects on humankind and how these effects could be harnessed to enhance and enrich human wellbeing, including life experience, productivity, performance, satisfaction, memory and creativity. Because of the significance of colour on humans, disciplines such as Colour Psychology, Colour Chemistry, Colour Therapy and Visual Ergonomics have emerged which have assumed considerable importance in day-to-day life.

A good grasp of Colour Psychology helps to create a psychologically satisfying, aesthetically pleasing, vibrant and energetic space, or a calm and tranquil environment by selecting the appropriate shades of colours depending on the need and occasion. This is crucially important in a fiercely competitive globalized environment characterized by anxiety, tension, disquiet and chaos where people are leading a stressful, restless and agitated life in a fast-paced world. In the circumstances, creating a relaxed, congenial and harmonious environment at home as well as at the workplace by painting the living and working environment with appropriate hues is of prime importance.

This need is paramount and should be addressed as a matter of great importance. Then only could we embark upon a colorful journey and paint our world with appropriate vibrant hues in order to unearth the boundless potential and transformative power that lies within us. However, there is a dearth of competent professionals, particularly in Sri Lanka who can proffer the right advice and guidance to clients in selecting appropriate colours for specific places such as the living room, bedroom, dining room, reading room, exercise room etc. in homes and public places such as hospitals, restaurants, coffee shops, gymnasiums theatres, prisons etc. for the human wellbeing. This issue has been further exacerbated due to hardly any academic interaction and collaboration, particularly between the Faculties of Arts, Science and Medicine.

The course unit system (CUS) developed in the USA enables students to pick and choose course modules from diverse fields so as to create complementarity and synergy; this in turn, leads to producing well-rounded and well-grounded creative graduates equipped with multiple competencies to address real-world issues more effectively. Though the CUS was introduced in our universities over 20 years ago, because of the heavy compartmentalization and fragmentation, course modules for degree programmed of a given faculty have been selected mainly from among the modules offered by the faculty concerned, thereby not deriving the key expected benefits from the CUS. Consequently, Sri Lankan universities have been hardly able to develop any cross-faculty academic programmed such as Colour Psychology, Colour Therapy, Music Therapy and such like. Therefore, it is imperative to make necessary interventions so as to facilitate and promote interfaculty degree programmed in Sri Lanka universities, paving the way for the development of such academic offerings jointly by the Faculties of Arts, Science, Medicine, Architecture etc. Moreover, cooperation and collaboration between faculties are needed to effectively address complex real-world issues such as SDGs which demand a holistic trans-disciplinary systems approach. Hence, the earlier such interventions are made, the better.

NPP drowning in sea of scams

Outgoing Treasury Chief Mahinda Siriwardena congratulates his successor Harshana Suriyapperuma in late June 2025 at the Finance Ministry

The Opposition is pressing for a one-day debate on USD 2.5 mn Treasury theft, which is more like a daylight robbery that had been kept under wraps by Treasury mandarins till ‘Free Lawyers’ made it public. However, the government is strongly opposed to the Opposition proposal. The Opposition is seeking consensus among

different parties to intensify the campaign against the government, struggling to cope up with a spate of controversies. Against the backdrop of the devastating debate on the coal scam, the NPP seems reluctant to face another over the theft of Treasury funds.

By Shamindra Ferdinando

USD 2.5 mn brazen heist at the Treasury several months ago and the bigwigs there obviously dragging their feet over the matter till it was brought to light recently, thanks to the Free Lawyers movement, which has dampened the NPP’s enthusiasm for May Day. The Treasury fiasco humiliated the cocky NPP leadership against the backdrop of damning report issued by the National Audit Office (NAO) that found fault with the government for awarding the coal tender for 2025/2026 period to Trident Champhar Limited of India in violation of tender procedures. The NAO emphasised that the Indian company shouldn’t have even been considered for the tender.

Even after the exposure of the scandalous handling of the coal tender, the NPP, in spite of some rumblings within the party, remained confident of overcoming the growing accusations regarding governance issues. But, the sudden revelation of the loss suffered by the Treasury, and pathetic efforts made by the NPP to suppress the truth, has caused irreparable harm to the ruling party. The arrogant NPP will have to use May Day to defend the government. Instead of preaching to the masses ad nauseum the corruption allegations against previous administrations, the NPP would have to explain such massive failures/corruption, particularly the loss of USD 2.5 mn.

There hadn’t been a previous instance of such an incident at the Treasury. The NPP will have to answer questions posed by ‘Free Lawyers,’ a civil society group that first raised the Treasury issue. On behalf of ‘Free Lawyers,’ its President Maithri Gunaratne, PC, former Governor of several provinces Rajith Keerthi Tennakoon, and Attorney-at-Law Shiral Lakthikala, targeted the government over the unprecedented Treasury heist. The Opposition, too, censured the NPP, with SJB leader Sajith Premadasa, MP, Chairman of Public Finance Committee (CoPF) Dr. Harsha de Silva, MP, and United Republican Front (URF) taking the lead.

The NPP’s excuses, based on claimed raids carried out by hacker/hackers targeting the Treasury, are untenable. The NPP’s position cannot be defended or supported against growing criticism. The coal scam and Treasury fiasco dominated social media, with the Opposition, as well as ordinary citizens, having a field day at the expense of the NPP, a political party that accused its opponents of waste, corruption, irregularities and mismanagement. Its successful propaganda campaigns, at the presidential and parliamentary polls, in September and November, 2024, respectively, were centered on fighting corruption.

Their anti-corruption platform appealed to the people for obvious reasons. Against the backdrop of bankruptcy, declared in May, 2022, after failing to meet debt commitments, the electorate rallied around the NPP that thrived on waste, corruption, irregularities and mismanagement, perpetrated by previous governments. Having bagged the executive presidency in September, 2024, the NPP assured the electorate that the Parliament would be cleansed of evils at the general election. President Anura Kumara Dissanayake declared that the people have been vested with the responsibility of cleansing the Parliament. Dissanayake went a step further when he addressed a public gathering at the 18th mile post on the Negombo-Colombo road. The NPP leader, who also leads the JVP, asserted that there was no need for an Opposition in Parliament and the House should be filled with NPPers.

Dissanayake based his assertion essentially on two failed No-Confidence Motions (NCMs) moved against Ravi Karunanayake and Keheliya Rambukwella in 2016 and 2023, respectively. The NPP/JVP leader found fault with Yahapalanaya and the Wickremesinghe-Rajapaksa government for protecting the two wrongdoers, hence the call to cleanse Parliament.

The results of the parliamentary election proved that the electorate responded very favourably to Dissanayake’s call. Of the 225-seat Parliament, the NPP secured 159 seats, including 18 National List slots. Having accused previous governments of shielding wrongdoers, Dissanayake easily directed the NPP’s steamroller parliamentary group to defeat the NCM moved against Energy Minister Punyakumara Dissanayake (National List) on 10 April, just a few days after the NAO report exposed the coal scam.

First ex-MP as Treasury Secy.

If its own hands are clean, there is no doubt that the NPP now deeply regrets the appointment of ex-NPP National List MP Harshana Suriyapperuma as the Secretary to the Treasury and the Finance Ministry. That appointment was made in June 2025 to fill the vacancy created by the retirement of Mahinda Siriwardana who, along with Governor of the Central Bank Dr. Nandalal Weerasinghe, played a significant role in the country’s post-Aragalaya recovery programme.

Suriyapperuma, who had served as Deputy Minister of Finance and Planning for just seven months, before being appointed the Treasury Secretary/Finance Ministry Secretary, is under heavy fire for suppressing the truth. No less a person than CoPF Chairman Dr. de Silva publicly accused Suriyapperuma of trying to undermine his committee. The SJB has demanded Suriyapperuma’s immediate resignation. Dr. Anil Jayantha succeeded as Deputy Minister of Finance and Planning.

Those who inquired into the crisis-hit Treasury are of the belief that 53-year-old Suriyapperuma lacked the much required experience to fill the shoes of Mahinda Siriwardana. Perhaps, the breach at the Treasury could have been averted if an outsider was not brought in place of Siriwardena. The recent reportage of the incident revealed that Suriyapperuma had been aware of the breach and sought to avoid appearing before the CoPF. The NPP could have responded to the developing situation differently if an ex-MP hadn’t been entrusted with the task of steering the Treasury/Finance Ministry. To make matters worse, President Dissanayake holds the Finance portfolio.

Although the government declared that the theft of USD 2.5 mn had been reported to the Criminal Investigation Department (CID) after initial detection made in January this year, controversy surrounds the failure on the part of law enforcement authorities to bring it to the notice of the courts. Maithri Gunaratne, appearing in Hiru last Saturday (25), questioned why the police failed to inform the relevant Magistrate if the government lodged a complaint in that regard.

Australia has confirmed irregularities in payments owed to their government. Regardless of NPP efforts to blame it on hacker/hackers, the truth is clear. Payments have been made to an account that hadn’t been in the original agreement between the governments of Sri Lanka and Australia. That is the undeniable truth that the NPP cannot suppress by propaganda.

The NPP should be ashamed that such a fraud had been perpetrated on a country still struggling to cope up with the economic destruction caused by the UNP- and the SLFP-led governments with the help of “mission impossible” type roles played by outside interests, especially during Gotabaya Rajapaksa’s tenure using the JVP/Aragalaya.

The world knows how the UNP perpetrated the Treasury bond scams with the direct involvement of the then Governor of the Central Bank Arjuna Mahendran, in February 2015 and March 2016. Regardless of that intolerable scam, the UNP made a desperate attempt to retain the services of the Singaporean as the Governor of the Central Bank. Party leader and the then Prime Minister Ranil Wickremesinghe demanded the re-appointment of Mahendran. That despicable move had to be dropped due to massive Opposition protests and growing public discontent over the Treasury bond scams.

The first Treasury bond scam carried out on 27 February, 2015 caused a direct loss of approximately Rs. 2 billion. On the instructions of Mahendran, the Treasury suddenly and arbitrarily changed the process of issuing Treasury Bonds. According to media reports at that time, higher interest payments, over the next 30 years, caused a further loss of around Rs. 145 billion.

Then Mahendran struck again. Caused further direct losses of more than Rs. 4 billion to the government through the fraudulent increase in interest rates as a result of the Treasury Bond issues on 27th March, 2016 ,and 29th March, 2016, in order to provide an undue advantage to connected primary dealers by indulging in further pre-meditated bond scams.

NPP on back foot

The ruling party put on a brave face with lawmakers and various others trying to play down the incident at the Treasury. Some pathetically tried to compare various accusations directed at the Rajapaksas with the incident at the Treasury which they conveniently blamed on hacker/hackers.

The NPP is facing an explosive mixture of issues. Both the coal and Treasury scams have brought immense pressure on the national economy and caused automatic deterioration. The resignation of Punyakumara aka Kumara Jayakody over the coal scam indicated that defeating the NCM moved against him was a strategic political blunder. Had the NPP asked the tainted first time Minister to step down and appoint a Presidential Commission to go into the coal scam, the NPP could have averted a major disaster. However, the Energy Minister and the Energy Secretary Udayanga Hemapala had to resign before the Parliament took up the NCM. Had the top NPP leadership bothered to peruse the executive summary of the NAO presented to Parliament on 7 April, the Party wouldn’t have tried to defend the minister.

Having championed a corruption-free political party system and then won both the presidential and parliamentary polls on that platform, the NPP executed the shocking move to move 323 containers out of the Colombo Port, in January 2025, without even any cursory checks. Those who perpetrated that operation used continuing port congestion as an excuse to clear red-flagged containers without mandatory physical checking. The NPP recently thwarted a bid by Opposition lawmakers, representing a parliamentary committee inquiring into the illegal release of containers, to summon President Dissanayake.

That committee, headed by Justice Minister Attorney-at-Law Harshana Nanayakkara, owed an explanation as to why President Dissanayake, in his capacity as the Finance Minister, shouldn’t appear before a House committee. President Dissanayake very often addresses Parliament on crucial issues. As the Minister in charge of Finance, the President should offer an explanation regarding the high profile container issue that tarnished the NPP’s image.

Three major issues in hand, namely the release of 323 containers, coal scam and theft at the Treasury, regardless of what various apologists say on mainstream and social media, have caused irrevocable damage to the party, let alone escapades involving the likes of Speaker Jagath Wickramaratne, Minister Lal Kantha, etc. The impact on the NPP can be ascertained only at an election. With the public increasingly aware of the growing accusations against it, the ruling party will do whatever possible to put off long delayed Provincial Council elections. Facing the electorate against deepening discontent among the public seems to be a frightening situation. It would be interesting to observe how a House committee, headed by Foreign Minister Vijitha Herath, appointed to explore ways and means to conduct Provincial Council polls, address the issue at hand.

When compared with the three major issues, the resignation of Asoka Ranwala, as the Speaker, in December, 2024, over his failure to produce the much-touted educational qualifications, seems unnecessary. Of course, Ranwala’s case attracted tremendous public attention at that time as the public really believed the NPP wouldn’t deceive them. Ranwala’s lie shocked the public. NPP theoretician Prof. Ranjith Nirmal Dewasiri had no qualms in publicly attacking Ranwala in the wake of the NPP defending the Speaker. But, subsequent NPP actions revealed massive manipulations that shamed the first post-Aragalaya government.

Having accused Ranil Wickremesinghe of squandering as much as Rs 16 mn to join his wife Prof. Maithree in the UK in September, 2023, the NPP has ended up facing far more serious accusations. The incident at the Treasury should be sufficient for the Opposition to move NCM against the government. Of course, the NPP got the numbers in Parliament to easily defeat the NCM but the consequences would be devastating. Those who still talk of recovering the missing USD 2.5 mn must be living in a dreamland. The UNP is labelled with Treasury bond scams (2015 and 2016) and the SLPP faulted with tax cuts (2019) and sugar tax scam (2020). The NPP will have to live with the coal scam and Treasury theft. The NPP will no longer be able to parade on political platforms as paragons of virtue. It would be pertinent to mention that the Presidential Commission appointed to probe the procurement of coal, since 2009, would be able to produce a report to meet the NPP’s expectations. All indications point to that and 2026 is going to be far more challenging, both in and outside Parliament, than the previous year.

NDB fraud

Examined together, the massive fraud at the National Development Bank (NDB), perpetrated during the 2024-2026 period, and the Treasury incident, they underscore the vulnerability of the entire banking system. The 13.2 bn NDB fraud and theft of USD 2.5 mn from the Treasury exposed the regulator, the Central Bank of Sri Lanka, in respect of the NDB. The situation at the NDB cannot be examined without taking into consideration that Ernst & Young is the external auditors of the NDB and its Managing Partner Duminda Hulangamuwa functions as Senior Economic Adviser to President Dissanayake. People haven’t forgotten that Hulangamuwa had been mentioned as the possible successor of Mahinda Siriwardena before the NPP brought in Suriyapperuma. The Central Bank and Securities Exchange Commission (SEC) come under the purview of the Finance Ministry now embroiled in the expanding Treasury fiasco.

The Board of Directors at the NDB consists of Sriyan Cooray (Chairman), Kelum Edirisinghe (Director / Chief Executive Officer (Executive), Bernard Sinniah (Director /Non-Independent), Sujeewa Mudalige (Director /Independent), Kushan D’Alwis (Director/Independent), Kasturi Chellaraja (Director/Independent), Shweta Pandey (Director /Independent), Hasitha Premaratne (Director/Independent), Sanjaya Mohottala (Director (Non-Independent) and Shanil Fernando Director (Independent).

The issue at hand is how such a fraud went unnoticed for a considerable period of time and whether the top management simply ignored warning signs and the failure on the part of the regulator to intervene. Those who have read Mahinda Siriwardana’s ‘Sri Lanka’s Economic Revival: Reflections on the Journey from Crisis to Recovery’ would know the circumstances leading to the 2022 economic collapse. Soft spoken Siriwardana meticulously discussed how the then Central Bank leadership as well as the so-called economic leadership of the Pohottuwa party deliberately deceived President Gotabaya Rajapaksa. Siriwardena’s narrative is explosive. The book, launched before his retirement, with the participation of President Dissanayake, underscored the responsibility on the part of the political leadership and those running the banking system. Obviously Siriwardena’s work had no impact on the current dispensation as well as the top banking management.

The Opposition sees an apparent opportunity to heap pressure on the NPP as it contemplates counter measures. Their challenge is how to take remedial measures without jeopardizing the government. The IMF declaration that it is closely watching the theft of USD 2.5 mn from the Treasury must have added pressure on the government, ripped apart by the situation at the Treasury. Let us hope the government and the Opposition reach consensus on ways and means to improve financial discipline. Overall, the Parliament cannot absolve itself of the responsibility for enactment of laws and ensuring financial discipline and the fact that Sri Lanka needs to start repayment of debt in 2028.

The thought provoking essay published in The Island on 22 April by Usvwatte-aratchi- Some languages confine you; some languages free you prompted me to try to get this essay published if possible. It may help the readers to further their ideas about the importance of usage of language.

Personally, I have firsthand experience in this subject. I was exposed to two different cultures and two languages. In my formative years I was brought up in a certain culture and spoke the language pertaining to that culture/language (Sinhalese -Sri Lanka). I spent all my studying and working life (55 years) using a different language in a different culture (English -England). I must mention that this was not recently. It was the early 1960’s. I can claim that I have enough knowledge and experience to justify this essay topic. In this essay I shall be investigating some of the social aspects of language with the aid of some opinions put forward by some philosophers. Then I shall be making an attempt to see what psychology has to offer before I draw my own conclusions. I am treating social aspects as part and parcel of the culture. In my view these are inseparable entities, unless one chooses to forget his or her cultural upbringing to suit a particular society.

Adoption of different culture

Socially, learning a different language and adopting a different culture is quite possible. In this case what dominates is one’s attitude or the circumstances. Attitude is psychological. I am convinced that circumstances may lead to a change of attitudes. Having said that, we must not forget that there are individuals who have not taken the trouble to learn the language of the culture in which they live. This has created a lot of socio-psychological problems in the community in which they live. It is obvious that the problem is one of communication. The main tool of communication is language. Philosophers and psychologists have spent many years investigating how language helps us to communicate and also how it may lead us to misunderstand our own fellow human beings. Understanding others (family members, members of the community in which we live, and the strangers we meet) is one of the most important aspects of living.

An awareness of the problem of language goes back to the early Greek philosophers. Parmenides gave us the first example of an argument from language to the world, saying that if we speak of a thing it must exist, since we speak of a thing at various times, it must continue to exist in a particular form. It is recently that language itself has come to be studied in a systematic way. The two landmarks in this respect were the development of Linguistics and the philosophy of language in the 20th century. The great philosopher Bertrand Russell (1872-1970) has admitted that until he became a middle-aged man, he did not think about language per se, but regarded it as ‘transparent’. I am sure this is true with most of us although we are not of Russell’s caliber when it comes to philosophy. And one may not have to wait until one reaches one’s middle age.

Linguistics and philosophy of language

It will help us if we understand the difference between Linguistics and philosophy of Language. What linguists discover may be applied to philosophy, sociology, psychology, anthropology or physiology. But as a discipline of study, it remains independent of them. The philosophy of language is different. One of the modern philosophers John Searle (1932-2025) thought, by contrast to linguistics, philosophy tries to solve philosophical problems by analyzing the ordinary use, meaning and relations of words in a particular language. Searle goes on to say that language is crucial to understand human experience. In my opinion this is a very valid comment. At a very practical level we spend a lot of time sharing our experiences. Verbal communication is vital in this area. According to Canadian philosopher Ian Hacking(1936-2023) the influence of language on philosophy has been profound and almost unrecognized. He indicates, if we are not to be misled by this influence, it is necessary to become conscious of it, and to ask ourselves deliberately how far it is legitimate.

It is appropriate to bring in Ludwig Wittgenstein(1889-1951) at this point. He brought in the subject predicate theory of language. For example, if we say “John is king”. Where John is the subject and king is the predicate. Here existence requires substance. For Aristotle, forms do not exist independently of things—every form is the form of something. A “substantial” form is a kind that is attributed to a thing, without which that thing would be of a different kind or would cease to exist altogether. Wittgenstein supports Saint Augustine’s view that words are names of objects and that combinations of words have the sole function of describing reality. For example, if we point at a certain object, say a table and try to say to a child “this is a table”, the child will be confused as to what we are pointing at. Is it the colour, the tabletop or one or more of its legs This is called the ostensive definition method of teaching. Ostensive definitions lead to a variety of interpretations. The child may understand a particular case of this definition but there is no guarantee that she will be able to make a transition from one case to others like it.

Plato’s theory

J G Herder (1744-1803) pointed out the object to which we make reference may be defined by numerous different terms. How then can we justify direct, one to one correspondence-either of so many to one, or of one to so many? How are we going to deal with situations where a term describes something non-existent or only possible? Plato’s “Forms” theory cannot be applied here as anything that we can speak of already exists as a Form. Critics of this theory ask the question: “how can the world be crowded with so many imaginary objects?” We use words to describe and define. Is there any room for slang language? This comes in handy in our day to day social communication. Ostensive definition raises the questions that require a constant selection of what counts as relevant. In Aldous Huxley’s novel Chrome Yellow, the character Old Rowley is confused as to: Does ‘pig’ refer to the quality of having a curly tail? Or standing in rows to eat? Or being pink skinned and fat? Or wearing no clothes? When we use the word “piggishness” is it something inherent to pigs, or simply, a matter of how we choose to describe them?

How can we relate the above ideas and theories of language to our daily living? Daily living is a psychosocial activity.

Perceptions

The nature of language reflects the nature of our perceptions, and these are far from straight forward. Franz Brentano (1838-1917) developed his theory of intentionality: that every mental phenomenon has a relation of direction to its object, i.e. perceptions, desires, imagination etc. are related to what is perceived, desired or imagined. I presume this can be applied to any language irrespective of the culture (our social conditioning). Say for instance the images of art and the writings are given the ability to represent objects by imposing the intentionality on the object. Thus, when we assert that we see or believe something, we impose, by convention and intention, (that is true if and only if it is the case) on the statement, and these conditions are not contained intrinsically in the sounds that make it up, but in our perception of belief about the fact. I begin to wonder how this can be applied to non-physical and unseen situations. Sometimes our feelings and attitudes are unknown to the observer. A person may shout because he is angry but you cannot see the anger, only its physical expression. We will not be able to see the prior event that has led to the anger and the utterance. This shows that there is a limit to how much is revealed simply by observing a word and its context; there is often more than that can be said.

How can we account for unexpected linguistic behaviour? This has both social and psychological implications.

For a long time behavioural theorists believed that every development of the human being was controlled by environmental and social factors. This is similar to an ostensive explanation of meaning. It implied that everything was learnt through training and association. But Noam Chomsky (b.1928) was not happy with this idea. He thought language is a complex phenomenon and which is not taught bit by bit or systematically to infants. It is successfully acquired by (almost) everybody. From my own experience it is true to say that the difficulty in learning a second language is a very different process from that experienced with the first language. Chomsky argued that the first language is not in fact learned, but rather acquired through exposure to a particular language. According to him all languages share the same basic structure, and he called this “deep structure”, which may be expressed as surface structures through a process called ‘transformation’. Chomsky’s theory helps us to assume a universal system of grammar, which may generate an infinite number of particular sentences within a language. This explains how we may create sentences within a language we have never encountered before from a limited set of grammatical rules and this appears to be a rational scientific approach.

Social or psychological phenomenon

The argument/discussion whether language is a social or a psychological phenomenon requires much more investigation than this essay warrants. I have briefly brought in various philosophers’ work, which are invaluable to this topic in terms of philosophy of language. In conclusion I am tempted to state my own experiences as a bi-lingual person. When it comes to my first language, which is Sinhalese I don’t think I learned it. I heard my parents speaking it and I picked up a few words and I constructed my own sentences and gradually became proficient by accumulating more words. Of course, the proper grammatical use of even my own language was taught in school and not by my parents. Learning my second language i.e. English took a different form. I was taught to speak, read, and write English at school and I had to work harder at this than my first language, because my English was confined to the classroom situation only, i. e. I learnt English in a non- English environment. First language came naturally and the second one I had to learn to fit into the social and the education structure that prevailed at that time. Compulsion can motivate us to learn!I had no choice but to adopt myself culturally and linguistically as a university student in England and then as a university teacher in England. Apart from the native English students, I have taught students from different countries. European, African and Asian. I had the opportunity to intermingle with them and learned various different cultural and linguistic aspects. After almost a half a century in England, I am back to my own culture (language, customs, food etc) where I was born and started my life. I am still proficient in my own language Sinhalese. No conscious effort needed.

After all the foregoing arguments and philosophy that I have put forward, my own conclusion is Chomsky’s theories are more plausible to me than other theories on this issue. It is difficult to be exact and say whether language is a social or psychological phenomenon. From the above arguments, we can see that culture and language of a given society are tightly bound. This leads us to psychological adjustments in order to fit into a society. Who can deny that even the philosophers mentioned above have not been subjected to their own cultural environment?
