What is Transdisciplinary Philosophy?

This post is by David Ludwig (Wageningen University, Netherlands) and Charbel N. El-Hani (Universidade Federal da Bahia, Brazil) whose open access book Transformative Transdisciplinarity. An Introduction to Community-Based Philosophy has recently been published by Oxford University Press.



Specialization is inevitable in academia. Becoming an academic often means becoming a specialist in a narrowly defined research area that is carefully sheltered from too much outside influence. While this division of epistemic labor is central to disciplinary progress, it clashes with the reality of complex socio-ecological crises. Issues such as biodiversity loss, climate change, economic exploitation, or public health are not technical problems that can be solved by a specialist with narrowly defined expertise but require collaboration across disciplines, synthesizing insights from distinct fields such as biological and Earth sciences as well as economics and policy studies. 

While interdisciplinary synthesis matters, it is often not enough. Academics alone are not well-equipped to address socio-ecological crises but need to work with a large range of actors outside of academia such as community elders, engineers, farmers, fishers, medical practitioners, NGOs, policy makers, science communicators, social activists, teachers, or union workers. 

In the Brazilian fishing communities of Siribinha and Poças, who are two of the protagonists of our new book Transformative Transdisciplinarity, fishers often have fine-grained expertise about local ecosystem dynamics that is central to conservation efforts. Local school teachers and employees of the municipality are central to interventions that aim for sustainable impact. Getting things done requires stepping outside of the comfort zone of academic debates and therefore demands a broadened agenda from interdisciplinarity to transdisciplinarity.

Transdisciplinarity comes with intertwined epistemic and political promises. The epistemic promise of transdisciplinarity is to generate more robust research by bringing the expertise of diverse actors together. Expertise about social-environmental crises is widely distributed, and scientific research can greatly benefit from the inclusion of non-academic experts. In our book, we explore the expertise of fishers regarding a wide range of issues, including ecosystem dynamics and local varieties of fish. 

This epistemic promise is intertwined with a political promise of generating not only more robust science but also more just interventions. Transdisciplinary research benefits epistemically from diverse forms of expertise but simultaneously promises to include actors who commonly remain excluded from academic discourse. This political promise of transdisciplinarity is especially salient in places like Siribinha and Poças with long histories of colonial exploitation and racial oppression that continue to structure their disenfranchised position in Brazilian society.

For philosophers of science, the growing importance of transdisciplinary research is a fascinating issue, as it aligns with a wider shift in academia that is not exclusively framed through “transdisciplinarity” but also adjacent buzzwords such as “citizen science,” “civic science,” “co-creation,” “community-based research,” “multistakeholder platforms,” “participatory research,” “open science,” or “upstream engagement.” While all of these concepts have different historical legacies and connotations, they converge in highlighting the inclusion of diverse actors in a broader transdisciplinary trend of rethinking knowledge production in the context of socio-ecological crises.

These transformations in academia suggest a philosophy of transdisciplinarity that reflects on the many methodological and institutional challenges of more inclusive forms of scientific research. Our program of transdisciplinary philosophy, however, aims to go a step further: rather than only reflecting about transdisciplinary trends from the distance of the philosophical armchair, our book showcases that philosophers can become valuable collaborators in transdisciplinary research collaborations. 

Transdisciplinary practice requires navigating between very different practices of creating and validating knowledge, different ways of thinking about and being in the world, and different values and political positions of power. As philosophers who have collaborated in transdisciplinary projects in Brazil and Ghana for many years, our book explores the role of philosophers as mediators in these complex processes that require careful and caring navigation between diverse epistemologies, ontologies, and values. 

At the core, our book articulates an optimistic vision of the role of philosophy in a world of intersecting crises that give rise to deeply contested policy responses.  At the same time, philosophers often lack practical skills to become transdisciplinary philosophers. As philosophers, we’re usually trained to talk about people, not to talk with people. And we’re even less trained to work with people in making a difference together. Our book intends to provide guidance for philosophers who aim to change that.

Delusions in the DSM 5

This post is by Lisa Bortolotti. How has the definition of delusions changed in the DSM 5? Here are some first impressions. In the DSM-IV (Glossary) delusions were defined as follows: Delusion. A false belief based on incorrect inference about external reality that is firmly sustained despite what almost everyone else believes and despite what constitutes incontrovertible and obvious proof or evidence to the contrary. The belief is not one ordinarily accepted by other members of the person's culture or subculture (e.g., it is not an article of religious faith). When a false belief involves a value judgment, it is regarded as a delusion only when the judgment is so extreme as to defy credibility.

Rationalization: Why your intelligence, vigilance and expertise probably don't protect you

Today's post is by Jonathan Ellis , Associate Professor of Philosophy and Director of the Center for Public Philosophy at the University of California, Santa Cruz, and Eric Schwitzgebel , Professor of Philosophy at the University of California, Riverside. This is the first in a two-part contribution on their paper "Rationalization in Moral and Philosophical thought" in Moral Inferences , eds. J. F. Bonnefon and B. Trémolière (Psychology Press, 2017). We’ve all been there. You’re arguing with someone – about politics, or a policy at work, or about whose turn it is to do the dishes – and they keep finding all kinds of self-serving justifications for their view. When one of their arguments is defeated, rather than rethinking their position they just leap to another argument, then maybe another. They’re rationalizing –coming up with convenient defenses for what they want to believe, rather than responding even-handedly to the points you're making. Yo...

A co-citation analysis of cross-disciplinarity in the empirically-informed philosophy of mind

Today's post is by  Karen Yan (National Yang Ming Chiao Tung University) on her recent paper (co-authored with Chuan-Ya Liao), " A co-citation analysis of cross-disciplinarity in the empirically-informed philosophy of mind " ( Synthese 2023). Karen Yan What drives us to write this paper is our curiosity about what it means when philosophers of mind claim their works are informed by empirical evidence and how to assess this quality of empirically-informedness. Building on Knobe’s (2015) quantitative metaphilosophical analyses of empirically-informed philosophy of mind (EIPM), we investigated further how empirically-informed philosophers rely on empirical research and what metaphilosophical lessons to draw from our empirical results.  We utilize scientometric tools and categorization analysis to provide an empirically reliable description of EIPM. Our methodological novelty lies in integrating the co-citation analysis tool with the conceptual resources from the philosoph...
