Extended mind thesis:A Buddhist perspective

Published

on

After listening to Prof. Charitha Herath deliver his lecture at the World Philosophy Day Conference at the University of Peradeniya and then reading his excellent article, “Buddhist insights into the extended mind thesis – some observations” published in The Island (14.01.2026) I was prompted to write this brief note to comment on the Buddhist concepts he says need to be delved into in this connection. The concepts he mentioned are prapañca, viññāṇasota and ālayaviññāṇa. 

Let us look at the Extended Mind Thesis in brief. “The extended mind thesis claims that the cognitive processes that make up the human mind can reach beyond the boundaries of an individual to include as proper parts aspects of the individual’s physical and sociocultural environment” … “Such claims go far beyond the important, but less challenging, assertion that human cognition leans heavily on various forms of external scaffolding and support. Instead, they paint the mind itself (or better, the physical machinery that realises some of our cognitive processes and mental states) as, under humanly attainable conditions, extending beyond the bounds of skin and skull.

Extended cognition in its most general form occurs when internal and external resources become fluently tuned and deeply integrated in such a way as to enable a cognitive agent to solve problems and accomplish their projects, goals, and interests. Consider, for instance, how technological resources such as pens, paper, and personal computers are now so deeply integrated into our everyday lives that we couldn’t accomplish many of our cognitive goals and purposes without them (Kiverstein J, Farina M, Clark A, 2013).

It may be seen from the above that the Extended Mind Thesis is mainly concerned with human cognition. It seems that the tools that humans use to help them in the cognitive process are actually components of the extended mind. This is mentioned in Prof. Herath’s article as well. Though Buddhist theory of cognition does not imply such a relationship that involves the implements utilised in the process of acquiring knowledge, it proposes an inextricable relationship between the cogniser and the cognised. For instance, the eye-consciousness does not arise unless the object of cognition is present.

Reality of the world according to Buddhism is based on the relationship between the cogniser and the cognised. This theory is supported by the way in which Buddhism analyses the complex formed by the human personality and the world, which it does in three systems, expounding the bond between the two. First is the five aggregate analysis, second is the 12 bases (ayatana), and the third is the eighteen elements (dhatu). Whether this kind of entanglement is possible without some means of extending the  mind is an interesting question.

According to Buddhism, the mind is not a substance but rather a function that depends on it. There are three terms that are used to refer to mind and possibly these may indicate different functions though they are very often used as near-synonyms. The terms are mano, citta and viññāṇa. The term mano is used to refer to the aspect of mind that functions as one of the six sense-faculties. Mano is responsible for feelings and it also coordinates the functions of the other sense-faculties. Citta generally means consciousness or combinations of consciousness and the other mental-factors, vedanā, saññā, sankāra as seen in the Abhidhamma analyses.

The term Viññāṇa means basic awareness of oneself and it is also used in relation to rebirth or rebecoming. It has a special responsibility in being the condition for the arising of nama-rupa, and reciprocally nama-rupa is the condition for consciousness in the paticcasamuppada formula. Further, the term “consciousness-element” is also used together with five other items; earth-element, water-element, fire-element, air-element and space-element which seem to refer to the most basic factors of the world of experience, indicating its ability to connect with the empirical world (Karunadasa, 2015). In these functions, consciousness may assume some relevance in the Extended Mind Thesis.

Further if we examine the role of consciousness in rebirth we find that a process called the patisandhi-viññāṇa has the ability to transmit an element, perhaps some karmic-force, from the previous birth to the subsequent birth. In these functions the enabling mechanism probably is the  viññāṇasota, the stream of consciousness that Prof. Herath mentions, and which apparently has the ability to flow even out of the head and establish links with the external world.

It may be relevant at this juncture to look at the contribution made by Vasubandhu, the 4th Century Indian Buddhist philosopher. Vasubandhu’s interpretation of saṃskārapratyayaṃ vijñānam (consciousness conditioned by volitional actions) treats the stream of consciousness as the mechanism of continuity between lives. He emphasises that this stream continues without a permanent entity migrating from one life to the next. The “stream” manifests as the subject (ego) and object (external world), which are both considered projections of this underlying consciousness, rather than independently existing entities. Vasubandhu also had proposed a kshnavada  (theory of moments) to explain the stream of consciousness as consisting of arising and disappearing of consciousness maintaining continuity. These propositions may lend support to the Extended Mind Thesis.

Prof. Herath has mentioned the term prapañca (Pali – papañca) which generally means concepts.  In the context of the extended mind thesis it needs to be examined in relation to the Buddhist theory of perception, because the former mainly pertains to cognition. As mentioned by Prof Herath, Ven. Nanananda in his book “Concept and Reality” has discussed this subject emphasising the fact that in Buddhist literature the term papañca is used mainly in the context of sense-perception. He says that “Madhupindika Sutta” (Majjima Nikaya) points to the fact that papañca is essentially connected with the process of sense perception. According to the Buddhist theory of perception the final outcome or the final stage of the process is the formation of papañca. Following the formation of concept there is proliferation of the concept depending on the past experience the individual may have in relation to what is perceived.

This process of perception, as given inthe Madhupindika Sutta, leading to conceptual proliferation is at the beginning impersonal and in the later stages it becomes personal with the involvement of the human personality with its self-ego and craving and finally leading to total bondage. And this bondage is between the human mind and the external world. Whether this entails an extended mind needs to be researched as suggested by Prof. Herath.

The third concept that Prof. Herath referred to in his lecture is the Yogacara idea of ālayaviññāṇa. Yogacara in its analysis of consciousness has added two more types of consciousnesses to the six based on the six senses, which is the classification mentioned in Early Buddhism and the two additional ones are kleshaviññāṇa and ālayaviññāṇa. The latter is called the storehouse-consciousness as it carries the seeds of karma. It is also called the approximating consciousness as it approximates at two levels; in this birth by collection of defilements and in the next birth by carrying them across in rebirth.  The latter function may be relevant to the Extended Mind Thesis as it has the ability of projection beyond the body of the present birth and transmit to the body of the next birth.

If one is interested in researching into the concept of ālayaviññāṇa one must be aware that the three masters of Yogacara, i.e. Maithreyanata, Asanga and Vasubhandhu did not agree with each other on the nature of ālayaviññāṇa. While Maithreyanata was loyal to the early Yogacara idea that appeared in Sandhinirmocana Suthra, Asanga modified it to suit his thesis of idealism. Vasubandhu, however, adhered to the views of Early Buddhism and according to Kalupahana (1992) what he in his Trimsathika describes is the transformation of the consciousness and not the eight consciousnesses in the order in which they appear in Yogākāra texts. Here one is tempted to suggest that Asang’s idealism which propounds that the external world is a creation of the mind may lend support to the extended mind thesis. Idealism in Yogacara Buddhism may be another subject that needs to be researched in the context of the extended mind thesis.

Turning to recent research there is theoretical and speculative support from quantum theory for the idea of extended consciousness, but it remains a controversial area of research within physics, neuroscience, and philosophy. Several frameworks suggest that consciousness is not confined to the brain but is a fundamental, non-local phenomenon rooted in quantum processes that may connect minds to each other or the universe at large. (Wagh, M. (2024). “Your Consciousness Can Connect with the Whole Universe, Groundbreaking New Research Suggests”. Popular Mechanics. Retrieved from https://www.popularmechanics.com/scienc)

Finally, while it may not be clear whether the Extended Mind Thesis, as proposed by A. Clark and others (2013), has anything to do with consciousness it may be worthwhile to research into this matter from a Buddhist perspective, which will have to strongly bring into contention the factor of consciousness, which perhaps may have the potential to develop into an  Extended Consciousness Thesis.

Mannar’s silent skies: Migratory Flamingos fall victim to power lines amid Wind Farm dispute

Victims: Flamingos / Birds found dead in Mannar

By Ifham Nizam

A fresh wave of concern has gripped conservationists following the reported deaths of migratory flamingos within the Vankalai Sanctuary—a globally recognised bird habitat—raising urgent questions about the ecological cost of large-scale renewable energy projects in the region.

The incident comes at a time when a fundamental rights petition, challenging the proposed wind power project, linked to India’s Adani Group, remains under examination before the Supreme Court, with environmental groups warning that the very risks they highlighted are now materialising.

At least two flamingos—believed to be part of the iconic migratory flocks that travel thousands of kilometres to reach Sri Lanka—were found dead after entanglement with high-tension transmission lines running across the sanctuary. Another bird was reportedly struggling for survival.

Professor Sampath Seneviratne, a leading ornithologist, expressed deep concern over the development, noting that such incidents are not isolated but indicative of a broader and predictable threat.

“These migratory birds depend on specific flyways that have remained unchanged for centuries. When high-risk infrastructure, like poorly planned power lines, intersect these routes, collisions become inevitable,” he said. “What we are witnessing now could be just the beginning if proper mitigation measures are not urgently implemented.”

Environmentalists argue that the Mannar region—particularly the Vankalai wetland complex—is one of the most critical stopover sites in South Asia for migratory waterbirds, including flamingos, pelicans, and various species of waders. The sanctuary’s ecological value has also supported a niche with growing eco-tourism sector, drawing birdwatchers from around the world.

Executive Director of the Centre for Environmental Justice, Dilena Pathragoda, said the incident underscores the urgency of judicial intervention and stricter environmental oversight.

“This tragedy is a direct consequence of ignoring scientifically established environmental safeguards. We have already raised these concerns before court, particularly regarding the location of transmission infrastructure within sensitive bird habitats,” Pathragoda said.

“Renewable energy cannot be pursued in isolation from ecological responsibility. If due process and proper environmental impact assessments are bypassed or diluted, then such losses are inevitable.”

Conservation groups have long cautioned that the installation of wind turbines and associated grid infrastructure—especially overhead transmission lines—within or near sensitive habitats could transform these landscapes into lethal zones for avifauna.

An environmental activist involved in the ongoing legal challenge said the latest deaths validate earlier warnings.

“This is exactly what we feared. Development is necessary, but not at the cost of biodiversity. When projects of this scale proceed without adequate ecological assessments and safeguards, the consequences are irreversible,” the activist stressed.

The debate has once again brought into focus the delicate balance between renewable energy expansion and biodiversity conservation. While wind energy is widely promoted as a clean alternative to fossil fuels, experts caution that “green” does not automatically mean “harmless.”

Professor Seneviratne emphasised that solutions do exist, including rerouting transmission lines, installing bird diverters, and conducting comprehensive migratory pathway studies prior to project approval.

“Globally, there are well-established mitigation strategies. The issue here is not the absence of knowledge, but the failure to apply it effectively,” he noted.

The timing of the incident is particularly worrying. Migratory flamingos typically remain in Sri Lanka until late April or May before embarking on their return journeys. Conservationists warn that if hazards remain unaddressed, larger flocks could face similar risks in the coming weeks.

Beyond ecological implications, experts also highlight potential economic fallout. Wildlife tourism—especially birdwatching—contributes significantly to local livelihoods in Mannar.

 Repeated reports of bird deaths could deter eco-conscious travellers and damage the region’s reputation as a safe haven for migratory species.

Environmentalists are now calling for immediate intervention by authorities, including a temporary halt to high-risk operations in sensitive zones, pending a thorough environmental review.

They stress that protecting animal movement corridors—whether elephant migration routes or avian flyways—is a fundamental pillar of modern conservation.

As the controversy unfolds, one question looms large: can Sri Lanka pursue sustainable energy without sacrificing the very natural heritage that defines it?

Pathragoda added that for now, the sight of fallen flamingos in Mannar stands as a stark reminder that development, if not carefully planned, can carry a heavy and irreversible cost.

‘Weaponizing’ religion in the pursuit of power

Published

on

President Donald Trump; miscalculating in M-E / Ayatollah Khomeini; Architect of Iranian Revolution

A picture of US President Donald Trump apparently being prayed for by supporters, appearing in sections of the international media, said it all loud and clear. That is, religion is being flagrantly leveraged or prostituted by politicians single-mindedly bent on furthering their power aspirations.

Although in the case of the US President the trend took on may be an exceptionally graphic or dramatic form, the ‘weaponizing’ of religion is nothing particularly new, nor is it confined to only religiously conservative sections of the West. For example, in South Asia it is an integral part of politics. The ‘South Asian Eight’ are notorious for it and it could be unreservedly stated that in Sri Lanka, the latter’s ethnic conflict would be more amenable to resolution if religion was not made a potent weapon by ambitious politicians of particularly the country’s South.

The more enlightened sections of Christian believers in the US may not have been able to contain their consternation at the sight of the US President apparently being ‘blessed’ by pastors claiming adherence to Christianity. Any human is entitled to be blessed but not if he is leading his country to war without exhausting all the options at his disposal to end the relevant conflict by peaceful means.

More compounded would be his problem if his directives lead to the death of civilians in the hundreds. In the latter case he is stringently accountable for the spilling of civilian blood, that is, the committing of war crimes.

However, the US along with Israel did just that in the recent bombings of Iran, for instance. The majority of the lives lost were those of civilians. If the US President is endowed with a Christian conscience he would have paused to consider that he is guilty of ordering the taking of the life of another human which is forbidden in the teachings of Jesus Christ.

Moreover, the ‘pastors’ praying over the US President should have thought on the above lines as well. May be they were in an effort to curry the President’s favour which is as blame-worthy as legitimizing in some form the taking of civilian lives. Apparently, the realisation is not dawning on all Christian conservatives of the US that some of these ‘pastors’ could very well be the proverbial false prophets and the latter are almost everywhere, even in far distant Sri Lanka.

However, the political reality ‘on the ground’ is that the Christian Right is a stable support base of the Republican Right in the US. Considering this it should not come as a surprise to the seasoned political watcher if the Christian Right, read Christian fundamentalists, are hand-in-glove, so to speak, with President Trump. But it is a scathing indictment on these rightist sections that they are all for perpetrating war and destruction and not for the fostering of peace and reconciliation. Ideally, they should have impressed on their President the dire need to make peace.

That said, political commentators should consider it incumbent on themselves to point out that religion is being ‘weaponized’ in Iran as well. Theocratic rule in Iran has been essentially all about perpetuating the power of the clerical class. The reasons that led to the Islamic Revolution in Iran are complex and the indiscreet Westernization of Iran under the Shah dynasty is one of these but one would have expected Iran to develop from then on into a multi-party, pluralistic democratic state where people would be enjoying their fundamental rights, as enshrined in the Universal Declaration of Human Rights, for example.

Moreover, Iran should have taken it upon itself to be a champion of world peace, in keeping with its Islamic credentials. But some past regimes in Iran had vowed to virtually bomb Israel out of existence and such regional policy trajectories could only bring perpetual conflict and war. Considering the current state of the Middle East it could be said that the unfettered playing out of these animosities is leading the region and the world to ‘reap the whirlwind’, having recklessly ‘sowed the wind’.

However, religious fundamentalism-inspired conflict and war has spread well beyond the Middle East into almost every region since 1979, the year of the Islamic Revolution in Iran. So much so, knowledgeable opinion now points out that religious identity has come to replace nationalism as a principal shaper of international politics or “geopolitics”, as quite a few sections misleadingly and incorrectly term it.

Elaborating on the decisive influence of religious identity, the well known and far traveled Western journalist Patrick Cockburn says in his authoritative and comprehensive book titled, ‘The Age of Jihad – Islamic State and the Great War for the Middle East’ at page 428 in connection with the war in Chechnya ; ‘If nationalism was not entirely dead, it no longer provided the ideological glue necessary to hold together and motivate people who were fighting a war. Unlike the Islamic faith, it was no longer a belief or a badge of identity for which people would fight very hard.’ (The book in reference was published by VERSO, London and New York).

In his wide coverage of Jihadist Wars the world over Cockburn goes on to state that today a call from a cleric could motivate his followers to lay down no less than their lives for a cause championed by the former. The 9/11 catastrophe alone should convince the observer that this is indeed true.

However, as often pointed out in this column, there is no alternative but to foster peace and reconciliation if a world free of bloodshed and strife is what is being sought. Fortunately we are not short of illustrious persons from the East and West who have shone a light on how best to get to a degree of peace. Besides Mahatma Gandhi of India, who was the subject of this column last week, we have former President of Iran Mohammad Khatami, who made a case for a ‘Dialogue of Civilizations’ rather than a ‘Clash of Civilizations’.

The time is more than ripe to take a leaf from these illustrious personalities, for, the current state of war in the Middle East has raised the possibility of a war that could transcend regional boundaries. The antagonists are obliged to exhaust all the peaceful options with the assistance of the UN system. Besides, war cannot ever have the blessings of the sane.

Venerable Rahula Thera’s 35-year green mission and national Namal Uyana

Published

on

Venerable Rahula Thera

It was 35 years ago, on March 28, 1991, that Venerable Rahula Thera, then a young monk, embarked on a journey to the Na forest in Ulpathagama, Palagama, in the Anuradhapura District. Today, three and a half decades later, this mission stands as living proof of the enduring bond between Buddhist philosophy and the natural world.

Marking the 35th year of this green mission, Rahula Thera’s relentless dedication has transformed the National Namal Uyana into an environmental landmark admired not only across Sri Lanka but around the globe, as well.

When studying the life of Venerable Rahula Thera, one cannot ignore the profound connection between Buddhism and the environment. Buddhism is a philosophy deeply attuned to nature. The historical use of the sacred “Na Ruka” by all four Buddhas: Mangala Buddha, Sumana Buddha, Revata Buddha, and Sobhita Buddha — for enlightenment —demonstrates that from time immemorial, Buddhism has maintained a sacred bond with the Na tree. From the birth of Siddhartha to his enlightenment, the propagation of the Dharma, and even the great Parinirvana, all of these milestones unfolded in verdant, living landscapes.

Venerable Rahula Thera did not embark on the Namal Uyana mission seeking government support or personal gain. His commitment sprang from a deep devotion to the Buddha’s teachings on grove cultivation. A grove cultivator is one who spreads compassion for nature. As the Vanaropa Sutta teaches:

Venerable Rahula Thera reclaimed Namal Uyana which was then under the control of timber smugglers and treasure hunters. The term “Wanawasi” does not merely mean living in a forest; it signifies finding rest and enlightenment through nature, free from the destructive roots of greed, sin, and delusion.

Another defining aspect of Venerable Rahula Thera’s 35-year mission is the purification of the human mind. He has consistently taught the thousands who visit Namal Uyana that a person who loves a tree will never harm another human being. As the Dhamma proclaims:

It is important to remember that Venerable Rahula Thera devoted his life, without fear, speaking the truth and taking necessary action, tirelessly advancing the national mission he began. From 1991 to the present, he has worked with every government elected by the people, maintaining impartiality and independence from political ideology. Yet, he never hesitated to raise his voice fearlessly against any individual, of any rank or party, who committed wrongdoing.

Religious and Social Mission

The National Namal Uyana is not merely a forest; it is a magnificent heritage site, dating back to ancient times. Scattered across the landscape are boundary walls, the remains of ancient monastery complexes, and stone carvings believed to date back to the reign of King Devanampiyatissa. In earlier centuries, this sacred land had served as a meditation sanctuary for hundreds of monks. The name “National Namal Uyana,” by which this ecological and archaeological treasure is known today, was introduced by Venerable Rahula Thera in 1991. The government’s later recognition of the site as the National Namal Uyana stands as a significant achievement for both religion and national heritage.

Venerable Rahula Thera is a monk who has lived a life of renunciation. A striking example of this is his decision not to assume the position of Chief Incumbent of the National Namal Uyana Viharaya, instead entrusting the temple to the Ramanna Nikaya and its trustees. In doing so, he set a precedent for the contemporary Sangha. The Thera himself stated that he was merely the trustee of Namal Uyana, not its owner.

Legacy and Continuing Inspiration

The 35th anniversary of Venerable Wanawasi Rahula Thera’s arrival at Namal Uyana is not merely the commemoration of a period of time; it is a message of nature to future generations. Through his work, the Thera revived the ancient Hela tradition of loving trees and venerating the environment as something sacred. This religious and environmental mission remains unforgettable.

The revival experienced by Namal Uyana, after the arrival of Venerable Wanawasi Rahula Thera, is beyond simple description. Some of the major accomplishments achieved under his leadership include:

* Securing and protecting the largest Rose Quartz (Rosa Thirivana) reserve in South Asia.

* Restoring the Na forest spread across hundreds of acres, providing shelter to numerous rare plants and animal species.

* Transforming the area into a living centre for environmental education, offering practical learning experiences for thousands of schoolchildren and university students.

* Drawing the attention of world leaders and international environmentalists to Sri Lanka’s unique environmental heritage.

In recognition of his immense contribution to environmental conservation, Venerable Rahula Thera was honoured with the Presidential Environment Award and the Green Award in 2004—a significant moment in his life. Yet the Thera himself has always remained devoted to the work rather than the recognition it brings, making such appreciation even more meaningful.
