The debate on Buddhist eco-ethics emerged in the late 20th century and continues to the present day. Experts specializing in early Buddhist scriptures, such as German scholar
Lambert Schmithausen (
1997,
2000) and English Orientalist
Ian Harris (
1995), tend to take a historical standpoint, raising questions about the essence of Buddhist eco-ethics, which was largely born out of the practical need of connecting environmental ethics with Buddhist principles. Their concerns, together with those of other environmental ethicists, can be delineated into three macro perspectives. Firstly, there is a quest to identify intrinsic environmental values within Buddhism (
Harris 1995;
Kaza 1997;
Schmithausen 1997,
2000;
Keown 2007;
Ives 2013), exploring the feasibility of formulating an ecological moral framework based on diverse Buddhist teachings. Secondly, scholars (
Gross 1997;
James 2000;
Wu 2006;
Cavazza 2014;
Strain 2016) attempt to examine whether Buddhist doctrines can support environmental ethical theories like deep ecology, though Arne Naess takes Buddhism, along with Christianity and Western philosophies (such as Spinozist and Whiteheadian thoughts) as its fundamental premises (
Naess 1998, p. 205). Thirdly, some scholars (
Scicot et al. 2017;
Elverskog 2020;
Capper 2022) re-evaluate Buddhists’ attitude towards nature, which has recently sparked interest among environmental ethicists who seek to investigate how Buddhists should approach the surrounding environment in their spiritual pursuit. These three inquiries strongly suggest the imperative of discussing a holistic concept of Buddhist eco-ethics within the context of environmental philosophy.
2.1. The Internal Macro Perspective: Whether There Is Eco-Ethics in Buddhism
The possible embodiment of eco-ethics in Buddhism is a topic that scholars vary on, with two different emphases: the historical and the socialized. The former helps uncover a kind of authentic environmental ethics presented in early Buddhist scriptures, whereas the latter perceives Buddhist eco-ethics as a pioneering accomplishment stemming from Buddhists’ active engagement in environmental activities. Scholars, with emphases ranging from the historical viewpoint to the socialized one, are academically and meticulously categorized by
Donald Swearer (
2006, p. 124) as eco-apologists, eco-critics, and eco-constructivists. In fact, these groups sometimes overlap. To better delineate the macro perspective, this article takes a comprehensive look at these groups and analyzes them with two different emphases. In the debate, historical emphasis plays an important role in exploring Buddhist eco-ethics by prioritizing historical objectivity and questioning the uncritical assertion of Buddhist environmentalism. By examining ancient Buddhist scriptures and doctrines, it is argued that Buddhism lacks an inherent basis to support an eco-ethics within itself, thereby casting doubt on the future development of Buddhist environmentalism. Some scholars, like
Lambert Schmithausen (
1997,
2000),
Ian Harris (
1995),
Damien Keown (
2007),
Stephen Kaza (
1997), and
Christopher Ives (
2013), critically scrutinize early Buddhist classics, claiming that the coined concept “Buddhist eco-ethics” appears to be rather weak-founded. This is because early Indian Buddhism evolved and diversified over the course of millennia, and even though today’s Buddhism innovatively supports ecological ethics, we must pay attention to the historical examination of earlier documents. Therefore, cherry-picking Buddhist scriptures may compromise the historical objectivity valued by these scholars when addressing Buddhist eco-ethics.
Here, we take some examples. Schmithausen contends that an in-depth analysis or evaluation of early Buddhist texts does not inspire any efforts in nature preservation. This finding makes him believe that early Buddhism manifests its detachment from nature, criticizing that “believers may feel the need for, and hence tend to create the myth of, an identity of their re-interpreted, re-organized or creatively extended or changed tradition with the original one” (
Schmithausen 1997, p. 9). Harris, in his criticism, claims that the belief in the unity between nature and humanity lacks a doctrinal or historical foundation, ultimately rendering eco-Buddhism to “shift away from traditional Buddhist cosmology” (
Harris 1995, p. 199). British bioethicist Damien Keown expounds his views upon Harris’s work, highlighting that the contemporary pursuit of Buddhist eco-ethics “is driven by Westerner pursuing a green agenda” (
Keown 2007, p. 98). American eco-writer Stephen Kaza openly voices her reservations about the existence of an intrinsic ecological ethic embedded in Buddhism. She acknowledges that “it is unclear whether ecological practices are primarily motivated by Buddhist tradition or by American environmentalism” (
Kaza 1997, p. 244). American scholar Christopher Ives, based on his analysis of resources on Buddhist environmental ethics, mentions some weak points of current Buddhist environmental ethics. In this respect, Ives advocates for “the intrinsic value and rights of things without clarifying a legitimate Buddhist basis for doing so,” stating that it fails to “take into account historical Buddhist terms for and views of ‘nature’” (
Ives 2013, p. 542). In principle, the aforementioned scholars with skeptical opinions question the congruity of early Buddhism with environmental ethics, arguing that the foundation on which Buddhist eco-ethics rests is weak when analyzed from an internal perspective (that is, by examining Buddhist literature historically). For them, Buddhist eco-ethics represents an innovative outcome of contemporary Buddhist engagement with the ecological agenda. Alternatively, in Ives’ words, “eco-Buddhists are generally focused more on continuing their activism than responding to the skeptics” (
Ives 2017, p. 43). However, the historical research on early Buddhist texts, to some extent, provides conclusive evidence to discredit the existence of Buddhist eco-ethics in pre-modern Buddhism.
The historical survey encourages those with a critical eye to doubt whether a well-established Buddhist eco-ethic can be internally constructed, and challenges those who rely on the “lines of ‘how to imagine a Buddhist environmentalism’ or ‘we Buddhists also love nature’”(
Sørensen 2013, p. 84). As a matter of fact, when examined through a lens of historical objectivity, Buddhism appears to hold an incongruous position regarding environmental ethics, because there is limited evidence within early Buddhist scriptures and historical literature to support the existence of ecological ethics. In the skeptics’ opinion, early Buddhist texts on nature often reflect a pessimistic outlook and show an absence or a rejection of “certain key elements that define contemporary environmental ethics” (
Holder 2007, p. 114). These missing elements, such as nature’s intrinsic value and preference for the wilderness (
Holder 2007, p. 114), enhance the skeptics’ claim that early Buddhist texts lack an inherent framework for ecological ethics when adapting Buddhist concepts and philosophy to align with contemporary environmentalism. Furthermore, these skeptics may argue that Buddhist engagement with environmental concerns primarily stems from the assimilation of Buddhism into societal constructs, known as “engaged Buddhism,” rather than arising from the historical examination of Buddhist texts. Therefore, they strongly recommend that Buddhist eco-ethics be seen as a social phenomenon. In their mind, the evolving nature of Buddhism and its diverse interpretations indicate that the understanding of its stance on environmental ethics remains open-ended and subject to ongoing interpretations and discussions.
According to the platform of “engaged Buddhism,” Buddhist eco-ethics seems to emerge as a practical consequence of the engagement of Buddhism with current environmental paradigms. That is to say, Buddhist eco-ethics is a kind of socialized concept. Thus, the disparity between the historical and the socialized views highlights a central paradox in the study of Buddhist ecological ethics, contributing to a more nuanced exploration of the relationship between Buddhism and environmental ethics. It is essential to recognize that historical objectivity and the socialized “engaged Buddhism” need not be seen as adversarial. Skeptical scholars who question Buddhist eco-ethics often stress historical inquiry and objectivity, primarily examining the Indian Buddhist texts and the origins of Buddhism. However, they sometimes also tend to align themselves with engaged Buddhism, which intentionally fosters their own unique Buddhist ecological thinking.
We cannot deny the fact that the presence of skeptical scholars raising valid questions highlights the importance of acknowledging historians’ commitment to historical objectivity while promoting innovative ideas. In fact, many of them posit the combination of both perspectives. For example, though Schmithausen holds a skeptical opinion, he duly recognizes the necessity of valuing innovation. In this sense, it is paramount to realize that historical objectivity and socialized inclination do not necessarily have to stand in adversarial opposition. The queries posed by skeptical scholars revolve around the imperative nature of Buddhist eco-ethics. Regardless of personal proclivities or anticipations, supporters of novel thoughts must “acknowledge the historian’s and philologist’s commitment to historical and philosophical objectivity” (
Schmithausen 2000, p. 58). It is worth noting that the scaffolding of historical documents plays a significant role in many humanities disciplines. Therefore, the future development of Buddhist eco-ethics, amidst the delicate balance of historical and socialized emphases, remains a significant challenge that requires deep contemplation. Alongside the approach to examining early Buddhist documents, there is another group of scholars who respond to the tension between Buddhist philosophy and modern environmental ethics. They tend to take an external macro perspective when addressing Buddhist environmentalism; namely, they concentrate more on the problem of adaptation between Buddhism and various branches of environmental ethics.
2.2. The External Macro Perspective: Whether Buddhism Can Support Deep Ecology
In order to delve into the external exploration of Buddhism’s engagement with environmental philosophy, we take “deep ecology” as a case study, which echoes our later discussion of David Cooper and Simon James’ resistance to certain proposals from deep ecology and their inclination to connect virtue ethics with Buddhist eco-ethics. Arne Naess (1912–2009), progenitor of deep ecology, openly acknowledges the influence of Buddhism. He recognizes that Buddhism, alongside Christianity and related Western philosophies, offers the most immediate affirmation of its fundamental tenets (
Naess 1998, p. 205). Indeed, the congruence between Buddhism and deep ecology gives rise to numerous inquiries, reflecting an external macro perspective that discusses the adaptation of Buddhism to other environmental branches in the ongoing discourse on Buddhist eco-ethics. These inquiries can be broadly categorized into two main domains: theoretical mediation and practical application. Here, the former seeks to explore how Buddhism and deep ecology can be reconciled in theory, whereas the latter attempts to discuss the practical difficulties of combining Buddhism and deep ecology. This external perspective with two levels, to some extent, helps enhance our understanding of the relationship between Buddhism and environmental ethics, particularly within the context of deep ecology. By addressing these inquiries, both scholars and practitioners can go deeper into the potential of Buddhist eco-ethics and understand its implications for promoting sustainable and compassionate approaches to environmental issues.
For the possibility of mediating Buddhism and deep ecology, the first inquiry centers on theoretical mediation, that is, whether it is possible to reconcile Buddhism’s emphasis on human spiritual potential and its holistic orientation with deep ecology. Some scholars discern that deep ecology bestows equal value to all beings, animate and inanimate, within an ecosystem, while Buddhism, though not strictly homocentric, has been perceived as giving higher reverence to human life compared to other life forms. This discrepancy arises from the belief among many Buddhists that the spiritual potential resides exclusively within human existence, which contradicts the fundamental principles of deep ecology (
Gross 1997, p. 337). Moreover, the doctrine of interdependence in Buddhism demonstrates a strong tendency towards holism, which poses a conundrum when individual intrinsic values are emphasized by deep ecology. This dilemma creates a profound quandary in the realm of Buddhist eco-ethics, where individuals often find themselves at a crossroads, seemingly compelled to choose between holism and intrinsic value. This requires careful theoretical expansion before it can be overcome. For instance, British environmental philosopher
Simon P. James (
2000) adeptly draws inspiration from Buddhism’s Middle Way and Martin Heidegger’s philosophical ideas to develop a distinctly holistic conception of nature. James describes the deep ecologist’s experience in two moments: one is holistic, associated with the “dependency of individual beings,” and the other retains a sense of integrity or independence without dissolving everything into an undiversified, nihilistic blur (
James 2000, p. 371). With this distinct idea, James strives to construct a framework that aims to transcend the apparent dichotomy and enable a more nuanced understanding of the relationship between human beings, other life forms, and the environment. In some sense, his efforts contribute to the evolution of Buddhist eco-ethics and pave the way for a more balanced and integrated approach to environmental ethics. However, within the context of contemporary environmental ethics that encompasses concerns for future generations and even extraterrestrial beings, further deliberation is warranted to fully comprehend the nuanced connotations of “intrinsic value.” Consequently, there is an imperative need for a continuous exploration of its relationship with holism.
Regarding the practical implications of combining Buddhism and deep ecology, it appears that aligning deep ecology with strict Buddhist principles may be seen as excessively demanding in light of rapid economic and technological progress, as well as prevalent opulent lifestyles in contemporary society. The notion of “tread[ing] lightly on the Earth” (
Wu 2006, p. 24), central to deep ecology, necessitates one’s dedication to minimal consumption and material requisites as a path toward one’s self-realization in its purest form, which might be criticized for hindering the advancement of human civilization. Scholars, who support both deep ecology and Buddhism, advocate for restrained consumption and procreation as a means to incorporate Buddhist eco-ethics. For example, as a fervent adherent of the Buddhist faith, the well-known American Buddhist scholar Rita M. Gross thinks that Buddhism must act as a restraint against unrestrained opulence and procreation, even in the face of the prevailing cultural norms that endorse lavish consumption and prolific reproduction (
Gross 1997, p. 333). In her mind, veneration for the natural world, if in isolation, falls short of a necessary element to compose a comprehensive environmental ethics. Additionally, Daniel H. Henning, an American scholar of political science, observes the phenomenon of over-production and analyzes its underlying premise as “a short term orientation that is principally concerned with quantity, economic benefits, newness, and expediency, rather than with long-range quality or environmental considerations” (
Henning 2002, pp. 23–24). With this phenomenon in mind, Henning refers to the Buddhist economic counterculture proposed by the International Network of Engaged Buddhists and advocates for a Buddhist economic culture based on “interconnectedness, sustainability, and non-accumulation,” as well as ”other fundamental Buddhist values such as compassion, loving-kindness, and altruism combined with respect for all life” (
Henning 2002, p. 24). However, this countercultural approach embraced by Buddhism and deep ecology may confront severe criticism as it may not always align with productive policies prioritized by a society. Hence, balancing the principles of deep ecology, Buddhist teachings, and the realities of modern society requires a continuous examination and thoughtful engagement.
In fact, the analyses of Buddhism and deep ecology by Gross and Henning touch upon two significant inquiries within political economy: consumption and reproduction. Currently, a number of scholars like David Loy also write about “the conjunction of Buddhism and the environment primarily through critiquing existing structures of political economy” (
Lin 2022, p. 1192). However, from the perspective of political economy, intentionally pursuing simplicity and advocating reduced consumption and procreation may be perceived as practices unsuitable for certain societies. On the other hand, the practical efficacy of the ecological holism advanced by both Buddhism and deep ecology has been cast into doubt. Some scholars perceive it as “ethically vacuous” (
Strain 2016, p. 190), given that the Buddha Dharma offers limited guidance in the face of the formidable choices that we must tackle urgent challenges of a warming planet. In general, various explorations are essentially needed to address environmental crises by integrating Buddhist teachings with deep ecology. These explorations not only pertain to the intersection of Buddhism and deep ecology but also represent a crucial inquiry into the evolution of Buddhist environmental ethics.
Although there exists potential compatibility between Buddhism and deep ecology, some scholars like Cavazza still contend that “the arguments and terminology of ecosophy and Buddhist philosophies do not completely overlap” (
Cavazza 2014, p. 43). Accordingly, alternative approaches are needed to address the challenge of reconciling these arguments and eventually achieve the harmonious evolution of Buddhist eco-ethics. By analyzing the interaction between Buddhism and deep ecology, both theoretically and practically, we navigate the intricacies of Buddhist environmentalism from an external macro perspective. Consequently, it is imperative to delve into the third perspective of Buddhists and their activities.
2.3. The Perspective of Disciples: Whether Buddhists Are Friendly to Nature
The concept of Buddhist eco-ethics in contemporary environmental ethics undergoes scrutiny within academic circles. In addition to the internal macro perspective that focuses on Buddhist literature and teachings, as well as the external macro perspective that examines the interactions between Buddhism and other environmental ethics, it is also significant to consider the perspective of Buddhists themselves. Within a specific space–time context, Buddhists and their environmental practices are shaped not only by Buddhism itself but also by the particularity of their contexts. This aspect is highlighted by Swearer, who refers to them as eco-contextualists (
Swearer 2006, pp. 135–36). Given this perspective, this section will discuss the ongoing debate on Buddhists’ affinity towards nature. It is insisted that Buddhists and their activities did not prioritize nature or ecology to the same degree as modern environmentalists do. To support this position, American professors Daniel Capper and Johan Elverskog give their specific reasons. Capper emphasizes that the compassion of Buddhists solely targets humans and animals, which is biocentric in essence but lacks an ecocentric orientation demanded by “a viable environmental ethic” (
Capper 2022, p. 7).
Elverskog (
2020), in his book
The Buddha’s Footprint: An Environmental History of Asia, argues that early Buddhist communities and their followers were deeply concerned about prosperity, which inevitably leads to the exploitation and deletion of natural resources in their pursuit of economic power. This perspective suggests that Buddhism, as a tradition, was not inherently beneficial to the physical world. Though this is the case, we have to notice that Buddhism, like any living tradition, has evolved and adapted over time. While Buddhists may have demonstrated a historical neglect of nature, this does not preclude Buddhism from aligning with eco-ethical principles. Practically, Buddhism has showcased its capacity to transform and adapt to different contexts and challenges throughout history. For instance, when Buddhism was transmitted from India to China, it incorporated Daoist concepts and terminology to translate and elucidate Buddhist teachings via methods such as “analogy” or “matching the meaning”, namely,
geyi in Chinese. This adaptation eventually led to the emergence of various sects within Chinese Buddhism, including Tiantai, Chan, Huayan, and Pure Land Buddhism. Within the realm of eco-Buddhism, there are also numerous examples that highlight Buddhism’s adaptability. For instance, Mongolian Buddhism absorbed “the pre-Buddhist tradition in Mongolia of respecting environment through recognizing specific mountains, rivers, and other landscape features as being sacred, and decreeing that they were therefore forbidden for activities such as hunting or logging” (
Chimedsengee et al. 2009, p. 14). Subsequently, Mongolian Buddhism has developed the concept of “nagas,” which refers to nature spirits and prompts Mongolian Buddhists to protect nature. Similarly, alarmed by the Thai government’s granting of numerous concessions to timber companies in the name of economic progress, Phrakhru Pitak and other Thai monks responded by organizing tree ordination ceremonies and introducing sustainable agricultural techniques (
Darlington 2012, pp. 44–51). These examples prove that Buddhism has the potential to address environmental concerns and develop an eco-friendly perspective both in history and in contemporary society.
On the other hand, Buddhism is contended to align deeply with the natural world, emphasizing a harmonious relationship between Buddhists and nature. Some Thai scholars, such as Phramaha Sangvech Scicot, Apaporn Bulsathaporn, and Thaweesak Chooma, staunchly support this viewpoint, claiming that Buddhism has an impeccable record free of conquest, intrusion, or the subjugation of sentient life (
Scicot et al. 2017, p. 54). They expound that there exists a close relationship between Buddhists and nature. It is legendarily recorded that Prince Siddhartha Gautama, who later became the Buddha, attained enlightenment through his intensive meditation under the Bodhi tree in Bodh Gaya, India, and subsequently sought solace in natural environments like forests, mountains, and caves in the wilderness (
Scicot et al. 2017, p. 57). The Buddha himself highly praised the virtues of solitude and the tranquility of nature as conducive to one’s spiritual quest and liberation. Further, these Thai scholars claim that the practice of Buddhism in the presence of nature forms the foundation for seeking a harmonious relationship between humans and the natural world. Thus, the Buddha imparts to his followers the precept of partaking in the Earth’s bounty based on their bodily needs during their spiritual journey, rather than indulging in sensory pleasures. This perspective resonates with the principles of deep ecology, which advocate for a balanced and respectful relationship with nature.
These two viewpoints, one emphasizing Buddhists’ neglect of nature and the other highlighting a reverence for nature, diverge to a large extent. The former examines the historical actions of Buddhists, while the latter focuses on the connection between Buddhists and nature during their spiritual journey. These differing viewpoints naturally lead to disparate conclusions and interpretations regarding the relationship between Buddhists and nature. This diversity of viewpoints also reflects the dynamic nature of Buddhism as it evolves and adapts to different contexts and interpretations in history. In fact, the ongoing discourse regarding whether Buddhists embrace a friendly attitude towards nature is intricately linked to the ecological environment of a particular region (and also time), as well as the prevailing social atmosphere and policies. Therefore, the approach taken by scholars like Phramaha Sangvech Scicot, who solely focus on Buddhists’ practice in nature, appears insufficient to address the question of whether Buddhists are environmentally friendly. To better answer the question, we need to consider various specific social elements. For example, when discussing the activities of Chinese Buddhists in Dunhuang (located in the northwest of China, with a dry and often windy climate), a different result will emerge compared to that of Elverskog. In Dunhuang, desertification has become a prominent issue since the Han Dynasty, leading the monks to cultivate a deep sense of environmental stewardship. They actively involved local communities in conservation practices, such as tree planting and water preservation (
Xu and Wei 2015, pp. 26–27), showcasing the imperative for continuous and diverse investigations into the Buddhist perspective.
