“Felix Guattari suggests that the basic question assailing us today is “how to produce, tap, enrich, and permanently reinvent (our subjectivity) in order to make it compatible with the Universe of changing values.” In this sense, ecology embraces the complexity of our social ecology, the ecology of the artificial environment that we produce in our being and becoming. It encompasses all ecologies that are at once natural and manmade.”

~Amerigo Marras adds to Felix Guattari in Hybrids, Fusions, and Architecture of the In-Between.
