Based on this observation, I embarked on a dual journey of self-discovery (notably through the practice of Non-Violent Communication) and reflection on the causes of the contemporary ecological crisis. This dual endeavour led me, on the one hand, to change my priorities in life and, on the other, to venture beyond the beaten track of scientific practice to explore the interfaces between science and science policy, philosophy, or poetry. Thus, my book "Nature that makes us human", which combines science and philosophy, argues that the relationship of domination and exploitation that modern society maintains with nature is not an epiphenomenon: the entire modern social structure is based on a set of collective fictions that lead humans to reproduce relationships of domination. However, these collective fictions are false beliefs. There is no spirit, subject, human or culture on one side, and matter, object, animal or nature on the other; there is only a general movement of the cosmos and of life, which flows through us and to which we contribute. My latest book, "Comment la Terre vit en nous", which combines science and poetry, shows concretely how much we are an integral part of planet Earth, whether through the material elements that make up our bodies, the multiple channels of communication that connect us to other living beings, or the love of life, which is the most fundamental human need.
