Abstract

In a series of articles, three system ecologists, B. Patten, S. Jørgensen and M. Straškraba attempt to construct a new ecosystem ecology. In this effort, an innovative ecological definition of life that originates from the cognitive domain is prevalent. To be more specific, living entities are defined as those who make models of reality. Through the exploration of this definition, we will try to point out the ontological and the epistemological characteristics of the new ecology. These characteristics facilitate the integration of physicochemical, biological and human systems into a common framework. Indeed, system ecologists attempt to unify the inorganic and the organic world, including human beings, under a universal evolutionary scheme. This scheme is organized around an innovative scientific hypothesi, namely the exergy storage hypothesis
