“Diversity” Is “The Motor Driving Universal Energy”: Édouard Glissant’s (1928–2011) Relation and Watsuji Tetsurō’s (1889–1960) Fūdo

This paper critically examines Édouard Glissant’s philosophy of relation through the lens of Watsuji Tetsurō’s theory of fūdo (climate and milieu), arguing that Watsuji’s insights help address some of the tensions and limitations in Glissant’s thought. While Glissant foregrounds relationality as a dynamic process of cultural creolization, his emphasis on fluidity and opacity at times risks obscuring the material and environmental conditions that shape human interactions. In contrast, Watsuji’s fūdo provides a framework for understanding relationality as always embedded in specific climatic and spatial conditions, grounding Glissant’s poetics of relation in a more concrete phenomenological and ecological perspective. By integrating Watsuji’s attention to the reciprocal formation of human subjectivity and milieu, this paper argues for a more nuanced articulation of relational identity—one that does not merely resist fixity but also acknowledges the formative role of an (interconnected) place (or places) and environment (or environments). Ultimately, this comparative approach highlights the potential for a deeper ecological and material grounding of Glissant’s thought, offering a corrective to its occasional indeterminacy while reaffirming its decolonial aspirations. In doing so, it contributes to broader discussions on the intersections of environmental philosophy, postcolonial thought, and theories of intersubjectivity.
