Epistemic diversity and the politics of knowledge in plant disease management
Societal Impact Statement Xylella fastidiosa is a major plant pathogen affecting crops such as grapes, citrus, almonds, and olives, with potentially severe consequences for agricultural production and rural livelihoods worldwide. This paper examines the conflict around the management of the X. fastidiosa outbreak affecting olive trees in southern Italy. We show that the conflict cannot be reduced to a confrontation between science and “science de…
Kukêire kute piy kre
We discuss a collective effort by Mebengokré Indigenous people from the Amazon and academics from Brazil and Europe to foster dialogue about ecological experiences and epistemologies. Inspired by conversations and collaborative work that took place on the Indigenous Land, at the university, and online, we analyze the ecological relations between the agouti/ kukêire and the Brazilian nut/ piy . Partial overlaps between Mebengokré and academic ecol…
Reclaiming ‘responsible research and Innovation’ as a generative concept
This perspective commentary reflects on recent frustrations with the institutionalization of ‘Responsible Research and Innovation’ (RRI) in Europe and vibrant debates about the same notion in China. It argues that Chinese debates about RRI are not only of national relevance but provide an entry point for intercultural dialogues about ‘humanizing science’ that highlight both convergences and tensions between science systems. Reclaiming RRI as a ge…
Endogenous innovation and change
Agricultural innovations have often been framed within a narrow, modernist narrative of technological modernisation and yield improvements–economic targets that often do not take the needs and knowledges of local communities into account. We therefore propose to re-define the term as ‘endogenous innovation’ to emphasise community agency and epistemic empowerment, in analogy with endogenous development processes. We analyse case studies in Ghana i…
I know a lot about medicinal plants. I read, I watch, and I search
The study suggests that medicinal plant knowledge has evolved here through hybridisation, a process whose consequences are context-dependent, offering opportunities for revitalisation but also a risk of displacement. Dialogic exchanges across families, communities, languages, and media expand people's plant repertoire and strengthen community adaptive capacity. Yet when these exchanges lead to excessive standardisation, they risk eroding the dive…
Saving the Olive Trees? Ontological Politics and Plant Disease Governance in Apulia, Southern Italy
In Apulia, everyone wants to “save the olive trees”—yet what is to be saved is far from clear. Since 2013, the spread of Xylella fastidiosa and Olive Quick Decline Syndrome (OQDS) has devastated Southern Italy’s groves and triggered a highly contested phytosanitary crisis. This paper argues that the controversy cannot be reduced to technical uncertainty, knowledge disagreement, or economic interests alone; it is also an ontological conflict—a str…
Intercultural Education as Dialogue Between Knowledge Systems
It’s a Shame That You Can’t Afford Rent, But We Can Offer Epistemic Compensation. On Relating Epistemic and Social Justice
Research as a Mangrove
This study explores the challenges of realizing the emancipatory potential of transdisciplinary research and methodology through a case study involving researchers from the Federal University of Bahia and the community of Siribinha Brazil. The project aimed to prioritize community perspectives, critical reflexivity, and dialogue between diverse knowledge systems to address social-environmental challenges. However, three core challenges emerged: 1…
Caring policy-relevant knowledge? The case of the Brazilian Platform for Biodiversity and Ecosystem Services
Science-policy interfaces like the Brazilian Platform for Biodiversity and Ecosystem Services (BPBES) aim to provide policy-relevant knowledge that guides decision-makers in addressing the current biodiversity crisis. At the same time, dominant approaches to policy-relevant knowledge have been widely challenged for relying on a misguided linear model that treats science and policy as separate domains, presenting the former through depoliticized i…

Rivers across worlds
Water-related crises and disasters are increasing in frequency and severity. Integrated Water Resources Management (IWRM) has been established over the last few decades aiming to achieve sustainable and participatory water governance. However, this article argues that IWRM is often based on ontological exclusion in the sense that participation is conditional on adopting a dominant ontology of water as a natural resource. Drawing on the Ontologica…
Differentiation of Expertise in Local Communities
Indigenous and local expertise have become widely emphasized in debates about environmental conservation and sustainable development. However, the engagement of this knowledge into conservation and sustainable development efforts should avoid assuming that a local community has uniform knowledge or some sort of cultural consensus, unless there is evidence supporting this conclusion. Investigating expertise in local communities offers a relevant w…
Confrontation or Dialogue? Productive Tensions between Decolonial and Intercultural Scholarship
For several decades, intercultural philosophers have produced an extensive body of scholarly work aimed at mutual intercultural understanding. They have focused on the ideal of intercultural dialogue that is supported by dialogue principles and virtuous attitudes. However, this ideal is challenged by decolonial scholarship as one which neglects power inequalities. Decolonial scholars have emphasized the differences between cultures and worldviews…
Going upstream
Despite the growing emphasis on ontological pluralism in environmental policy debates, innovation within national state environmental governance and management remains limited. This article outlines a conceptual framework for ontological inclusion and exclusion to examine constraints and opportunities in Brazilian participatory water governance. This involves an ontological policy cycle of the Suaçuí state river basin, a participatory process for…
No Such Thing as Containment? Gene Drives for Conservation and the (Im)possibility of an Island
This article explores the use of islands as tools of geographical and intellectual containment - or what we call “islanding” - in the scientific and policy literature about gene drive technologies in conservation. In the first part of the article, we explore the narrative of contained gene drive use on islands and discuss how it juggles notions of localness and localization of gene drives and their (test) releases. We question the possibility and…
Questions to David Ludwig
The conceptual potential of ‘more‐than‐human care’
As dominant approaches to biodiversity loss and climate change continue to fail in mitigating current socio-environmental crises, scholars and activists are exploring novel conceptual frameworks to drive transformative change in conservation. Among these, more-than-human care has emerged as a concept at the intersection of feminist debates about care and post-humanist discussions around the more-than-human. Although more-than-human care is increa…

Science as a site of inequality
Transdisciplinary Philosophy of Science
Transdisciplinary research knits together knowledge from diverse epistemic communities in addressing social-environmental challenges, such as biodiversity loss, climate crises, food insecurity, and public health. This article reflects on the roles of philosophy of science in transdisciplinary research while focusing on Indigenous and other subjugated forms of knowledge. We offer a critical assessment of demarcationist approaches in philosophy of …
Navigating between Promises and Realities of Transdisciplinary Research for Environmental Conservation
Transdisciplinary approaches combining technical perspectives with qualitative insights from the social sciences and non-academic stakeholders have emerged as a promising way to address the complexity of current socioenvironmental crises. However, transdisciplinary incorporation of diverse interests, knowledge, and worldviews requires acknowledging and addressing inherent inequities. Our case study combines two complementary transdisciplinary stu…
Pluralist Ethnobiology
In the introduction to this special issue on ethnobiology and philosophy, we consider how the included papers show that ethnobiology is an inherently pluralist project that has a unique potential to foster inter- and transdisciplinary perspectives on issues such as the complex multispecies relations between humans and non-humans that one finds in livelihood practices such as farming and fishing, in conservation management, or in industrial resour…
Gene Drives as Interventions into Nature
Gene drives are potentially ontologically and morally disruptive technologies. The potential to shape evolutionary processes and to eradicate (e.g. malaria-transmitting or invasive) populations raises ontological questions about evolution, nature, and wilderness. The transformative promises and perils of gene drives also raise pressing ethical and political concerns. The aim of this article is to arrive at a better understanding of the gene drive…
Advancing co-production for transformative change by synthesizing guidance from case studies on the sustainable management and governance of natural resources
Co-production has become paramount for scientists, practitioners and social groups of Indigenous peoples and local communities of rural and urban areas to deliver transformative changes that enhance sustainability. Co-production should result in knowledge that is credible, legitimate and usable to enable sustainable outcomes effectively. However, this is not always the case due to challenges related to differences between scientific and Indigenou…
Overlapping ontologies and Indigenous knowledge. From integration to ontological self-determination
Revamping the Metaphysics of Ethnobiological Classification
Ethnobiology has a long tradition of metaphysical debates about the "naturalness," "objectivity," "reality," and "universality" of classifications. The work of Brent Berlin has been especially influential in developing a "convergence metaphysics" that explains cross-cultural similarities of knowledge systems through shared recognition of objective discontinuities in nature. Despite its influence on the development of the field, convergence metaph…
Does Cognition Still Matter in Ethnobiology
Ethnobiology has become increasingly concerned with applied and normative questions about biocultural diversity and the livelihoods of local communities. While this development has created new opportunities for connecting ethnobiological research with ecological and social sciences, it also raises questions about the role of cognitive perspectives in current ethnobiology. In fact, there are clear signs of institutional separation as research on f…
Ethnoontology
This article outlines a program of ethnoontology that brings together empirical research in the ethnosciences with ontological debates in philosophy. First, we survey empirical evidence from heterogeneous cultural contexts and disciplines. Second, we propose a model of cross-cultural relations between ontologies beyond a simple divide between universalist and relativist models. Third, we argue for an integrative model of ontology building that sy…
Beyond the divide between indigenous and academic knowledge
Transdisciplinary research challenges the divide between Indigenous and academic knowledge by bringing together epistemic resources of heterogeneous stakeholders. The aim of this article is to explore causal explanations in a traditional fishing community in Brazil that provide resources for transdisciplinary collaboration, without neglecting differences between Indigenous and academic experts. Semi-structured interviews were carried out in a fis…
Letting Go of “Natural Kind”
This article uses the case study of ethnobiological classification to develop a positive and a negative thesis about the state of natural kind debates. On the one hand, I argue that current accounts of natural kinds can be integrated in a multidimensional framework that advances understanding of classificatory practices in ethnobiology. On the other hand, I argue that such a multidimensional framework does not leave any substantial work for the n…
The objectivity of local knowledge. Lessons from ethnobiology
This article develops an account of local epistemic practices on the basis of case studies from ethnobiology. I argue that current debates about objectivity often stand in the way of a more adequate understanding of local knowledge and ethnobiological practices in general. While local knowledge about the biological world often meets criteria for objectivity in philosophy of science, general debates about the objectivity of local knowledge can als…
Indigenous and Scientific Kinds
The aim of this article is to discuss the relation between indigenous and scientific kinds on the basis of contemporary ethnobiological research. I argue that ethnobiological accounts of taxonomic convergence–divergence patters challenge common philosophical models of the relation between folk concepts and natural kinds. Furthermore, I outline a positive model of taxonomic convergence–divergence patterns that is based on Slater's ([2015]) notion …
The Challenges of Symmetrical Dialogue
This article explores ways to promote symmetrical dialogue among knowledge-practices of artisanal fishing communities, primary education teachers, and academic researchers in the state of Bahia, Brazil. We describe multiple engagements in an inter- and transdisciplinary project that integrates research, educational, and conservation activities in two communities living in an estuarine ecosystem. Most community members dedicate their efforts to fi…
Cultural consensus and intracultural diversity in ethnotaxonomy
BackgroundTraditional fishing communities are strongholds of ethnobiological knowledge but establishing to what degree they harbor cultural consensus about different aspects of this knowledge has been a challenge in many ethnobiological studies.MethodsWe conducted an ethnobiological study in an artisanal fishing community in northeast Brazil, where we interviewed 91 community members (49 men and 42 women) with different type of activities (fisher…
Intercultural science education as a trading zone between traditional and academic knowledge
Intercultural science education requires negotiations between knowledge systems and of tensions between them. Building on ethnographic fieldwork and educational interventions in two farming communities in the Northeast of Brazil, we explore the potential of science education to mediate between traditional and academic knowledge. While traditional knowledge shapes agricultural practices and interactions with the environment in the villages of Cora…

Back by popular demand, ontology
In this paper we analyze relations between ontology in anthropology and philosophy beyond simple homonymy or synonymy and show how this diagnosis allows for new interdisciplinary links and insights, while minimizing the risk of cross-disciplinary equivocation. We introduce the ontological turn in anthropology as an intellectual project rooted in the critique of dualism of culture and nature and propose a classification of the literature we review…
Taking fishers' knowledge and its implications to fisheries policy seriously
Sustainable fishing is one of the most pressing challenges for mankind and requires insightful knowledge of the drivers that may foster or hinder predatory exploitation. It has been widely recognized that Indigenous and local knowledge can contribute to biodiversity conservation and sustainable use of resources, such as fisheries, worldwide. Nevertheless such knowledge continues to be marginalized and unacknowledged by a range of academic scienti…

Against the New Metaphysics of Race
The aim of this article is to develop an argument against metaphysical debates about the existence of human races. I argue that the ontology of race is underdetermined by both empirical and nonempirical evidence owing to a plurality of equally permissible candidate meanings of “race.” Furthermore, I argue that this underdetermination leads to a deflationist diagnosis according to which disputes about the existence of human races are nonsubstantiv…

Conhecimento Tradicional e Políticas Públicas
No Brasil, a formulação da política de defeso não leva em conta o conhecimento tradicional, que é, via de regra, marginalizado e não reconhecido perante às políticas públicas que as atingem. Nesse sentido, encontramos uma marcada incompatibilidade entre o conhecimento de pescadores artesanais do estuário do rio Itapicuru, norte da Bahia, sobre o período reprodutivo de alguns animais marinhos, e seus atuais defesos. Levando-se em conta esse tipo d…
Global Epistemologies and Philosophies of Science
In this chapter, we argue that in order to understand the interdisciplinary and transdisciplinary dialectics in sustainability science, it is useful to see sustainability science as a kind of management science, and then to highlight the hard-soft distinction in systems thinking. First, we argue that the commonly made natural-social science dichotomy is relatively unimportant and unhelpful. We then outline the differences between soft and hard sy…

Hysteria, race, and phlogiston. A model of ontological elimination in the human sciences
Measurement of Religion as Perceptual Set
Three well-known, standardized questionnaires were used as the cognitive measures. The first of these was the Belief Pattern Scale: Attitude of Religiosity developed by Kirkpatrick. A high score on this scale reflects approval of the organized church and of its dogma. The test-retest reliability of this measure is .94. The second measure was a combination of two scales developed by Chave and Thurstone, and are called the Reality of God Scale and …
Positive Mental Health of Workers as Related to Memory Optimism, Work Competency and Personified Values
The content analysis of the life and work stories including memories of pleasant and unpleasant experiences and personified values of 143 workers were made as a basis of obtaining indices of positive mental health. The categories used for assessing mental health were: (1) self-regard, (2) maturity, (3) personality organization, (4) relation to environment. These factors, as well as the total mental health index, were correlated with measures of m…
Development of Religious Perception — Integration of Life
A close look is given to the understanding of faith as the integrating thrust of life in this article. One of the basic problems facing the modern Christian is the compartmentalization of his faith because of conflicting values in different aspects of his life. The development of a true religious perception, however, is the integration of the different facets of life around one's faith by the power of the Holy Spirit. Implications of this concept…
Letters to God
Religious concepts of three age groups of children attending Christian schools (2nd, 5th and 8th grades) are compared. The basic hypothesis of the study is that in an atmosphere of religious instruction, the child's perception of God will move from external truth to the internalization and personalization of his faith. The results show that the concept of God does change during these developmental years from a transcedent figure to a more persona…
Self Identity and Morality
A close look is given to the motivational basis for moral behavior. One aspect of morality is concern for the needs and wishes of others. The motivation for such consideration is seen as related to one's self-identity. A Christian's identity as a child of God can thus become the motivation force for moral behavior

Universal Design for Virtual Worlds
We describe three broad approaches to the issue of accessibility design within Virtual Worlds. Our intent is to stimulate the thinking of content designers within Virtual Worlds about these approaches. Approach 1: Minimal accessibility design principles incorporated into the Virtual World For much of the current state of Virtual Worlds, this is the default situation: Minimal consideration has been given during design or construction to accessibil…
Beyond Physicalism and Dualism
Although Hilary Putnam has played a significant role in shaping contemporary philosophy of mind, he has more recently criticised its metaphysical foundations as fundamentally flawed. According to Putnam, the standard positions in the philosophy of mind rest on dubious ontological assumptions which are challenged by his “pragmatic pluralism” and the idea that we can always describe reality in different but equally fundamental ways. Putnam consider…
Language and Human Nature
Holism in interwar Germany provides an excellent example for social and political influences on scientific developments. Deeply impressed by the ubiquitous invocation of a cultural crisis, biologists, physicians, and psychologists presented holistic accounts as an alternative to the "mechanistic worldview" of the nineteenth century. Although the ideological background of these accounts is often blatantly obvious, many holistic scientists did not …

Extended cognition in science communication
The aim of this article is to propose a methodological externalism that takes knowledge about science to be partly constituted by the environment. My starting point is the debate about extended cognition in contemporary philosophy and cognitive science. Externalists claim that human cognition extends beyond the brain and can be partly constituted by external devices. First, I show that most studies of public knowledge about science are based on a…

Read together, the national explorations of the special section make visib…
Global challenges, Dutch solutions? The shape of responsibility in Dutch science and technology policies
The Netherlands has a well-established tradition of gearing science and technology to economic interests as well as societal and ethical concerns.
