This research is based on the assumption that we re living in an unparalleled moment of planetary transformation, where a crisis of the Anthropocene becomes evident, and that, to expand our thinking, imagining, and feeling horizons, intending to rebuild the axis of life on this planet, it s urgent to value the body s sensitive dimensions as alternatives to the objectifying approaches perpetrated by rationalist, colonizing, and capitalist Western epistemological traditions that have brought us here. Using as its core the somatic approach of Body-Mind Centering experiential anatomy, this research intends to consider some principles born from its practices, in dialogue with theoretical reflections by contemporary thinkers, through diffractive methodology, as proposed by Donna Haraway (2004, 2019) and Karen Barad (2007, 2012, 2017). The issue investigated here deals with how a physical matter poetics can contribute to contemporary thought and art that is committed to the task of generating a micropolitical action-posture to reconfigure a body s presence and action powers in regards to the environment, both on stage and in life. The research is theoretical-practical, and intends to investigate the notions of cellular knowledge and the performativity of matter, sympoietically connecting insights stemming from personal practice to experience reports and creative resonance generated in the Laboratórios Performativos de Anatomia Sensível [Sensitive Anatomy Performance Workshops] (offered in 2020 and 2021), as well as perspectives from quantum physics, biology, somatics, dance and social sciences. Through the interplay of these different writing registers, the dissertation attempts to fabulate a type of Body-Mind Centering poetics, understood as a methodology for speculative body fabulation.
