This chapter reflects on the importance of expanding the ecological approach beyond the descriptive and scientific analysis of the relationships between living organisms and their environment, in order to develop a philosophical ecology capable of addressing the ontological, epistemological, and ethical dimensions of thought. Philosophical ecology is not merely an application of descriptive ecology; rather, it involves the use of ecology’s meta-principles—such as heteronomy, symbiosis, hybridization and sympoiesis—as tools for philosophical reflection. What changes first and foremost is the ontological perspective, which reveals the impossibility of understanding human predicates within an essentialist and autarkic framework. Philosophical ecology aims to show that the environmental crisis is not simply a matter of resource exploitation, but the result of a flawed mode of thinking.
