In the Three Ecologies, Guattari proposes that there must be significant modifications to the social and material environment, without which there can be no changes to the mentalities that perpetuate capitalism. Guattari says that here, we are in “the presence of a circle that leads [him] to postulate the necessity of founding an "ecosophy" that would link environmental ecology to social ecology and to mental ecology”. What happens to humanity is “therefore by mutual universal participation ... nothing happens in man that does not have a bearing on the elements which constitute the universe” (121). For Guattari it is an ecosophical society that can counter the machine of integrated capitalism but this requires a different way of thinking. It requires that we understand ourselves, our society, and the ecosystem we inhabit as differing yet linked scales of ecology.
Central to learning to ‘think transversally’ is being part of communities that learn to act transversally. For Guattari there is a paradox at work here, on the one hand, the continuous development of new techno scientific means to potentially resolve the dominant ecological issues and restate socially useful activities on the surface of the planet, and, on the other hand the inability of organised social forces and constituted subjective formations to take hold of these resources in order to make them work (Guattari, 2104: 31?).
