This page is still under construction. Meanwhile, my book is entirely dedicated to exploring the idea of milieu in environmental ethics, and shorter texts on are available under Research and Academic Papers.
This idea of Milieu is inspired by Watsuji Tetsuro (1889-1960)’s concept of fuudo. The milieu is the “environment” as it appears covered by web of significations and symbols from the standpoint of a subjective human. We are constantly in dynamic cycles of codetermination with the milieu.

The concept of milieu recognizes the diversity of cultures anchored and mutually influencing in different milieus, and how these mutually shape each others. But it has some limitations in the form developed by Watsuji: Bounded communities assumption, no mention of responsibility and internal mechanisms of oppression and domination, no mention of sustainability.
To address these limitations, I developed the framework of the milieu, combining Watsuji’s ideas with Augustin Berque insights (the idea of the milieu as matrix-imprint), and placing this discussion within today’s context of global environmental crisis and the need for intercultural dialogue for sustainability. The framework of them milieu is developed in my doctoral thesis (see below) and my first book.

The Milieu as Common Grounds for Global Environmental Ethics
Doctoral dissertation – Abstract
This doctoral dissertation develops the concept of milieu (fūdo) inspired by the Japanese Philosopher Watsuji Tetsurō and applies it in the fields of environmental ethics and global political philosophy. It aims at building a motivational framework that supports sustainable ways of life and that can be consensual in the global context of pluralism of worldviews. The concept of milieu captures how we act within and perceive our surrounding environment as covered by webs of meanings and values that are culturally, historically and geographically situated. It covers the external dimension of relational interdependence, the internal dimension of phenomenological experience, the temporal dimension of dynamic changes and the spatial dimension of global interconnection. Individuals are shaped by and shaping the milieus they are living in. Insofar as individual phenomenological agents contribute to shaping their milieu, they are morally responsible for the imprints left by their ways of life. Individual moral responsibility for environmental harm is thus rooted in the inseparable relation between individuals and their milieu, and directed towards sustainability. Further, if flourishing human life is concretely intertwined with meaningful adaptable and nurturing milieus, then these must be included in the definition of sustainability. Finally, as most environmental problems have a global scope that goes beyond situated milieus, the question of how to build common grounds in the context of pluralism of worldviews is addressed.
