The 21st century has seen the rise of “environmental philosophy”, concerned with the problematization of the global ecological crisis. In all this bibliography, Felix Guattari’s’ contributions remain relegated –even when he should be acknowledged as one of the first contemporary thinkers to develop an explicit environmental philosophy as shown in his work The three ecologies. This article proposes an analysis of the problematic center of this pioneering and foundational work for environmental philosophy. Thus, it insists on the importance of returning to the original text; of revising its main topics –dedicating a section to each ecosophical domain (mental, social, environmental); and of upholding its relevance even in the light of the current literature in the area of environmental philosophy. Furthermore, in this analysis, the successes and flaws of its wagers and forecasts are considered: it is to note that its unfulfilled practical hope contrasts with its sharp theoretical diagnosis. In consequence, the present text argues that this work not only passes the test of time, but also fulfills the purpose of clarifying the current planetary catastrophe.
