Resonance and Radical Embodiment Vicente Raja Rotman Institute of Philosophy, Western University Western Interdisciplinary Research Building 1151 Richmond Street North London, Ontario, Canada, N6A 5B7 E-Mail: vgalian@uwo.ca vicendio@gmail.com Web Page: https://westernu.academia.edu/VicenteRaja Abstract One big challenge faced by cognitive science is the development of a unified theory that integrates disparate scales of analysis of cognitive phenomena. In this paper, I offer a unified framework that provides a way to integrate neural and behavioral scales of analysis of cognitive phenomena — typically addressed by neuroscience and experimental psychology, respectively. The framework is based on the concept of resonance originated in ecological psychology and aims to be the foundation for a unified theory for radical embodiment; that is, a unified theory for that dissident part of cognitive science that shares a methodological commitment to dynamic systems theory and remains skeptical about the adequacy of mechanism and representationalism as the guiding ideas in the field. In the course of my presentation, I analyze different issues regarding the requirements and constraints unification poses to radical embodiment. Keywords: resonance; dynamical explanation; unified framework; non-mechanistic, non- representational cognitive science Acknowledgements I am grateful to Michael Anderson, Jonathan Bowen, Tony Chemero, Valerie Hardcastle, Tom Polger, and the audience of the meeting ‘Reconceiving Cognition’ organized by the Centre for Philosophical Psychology at the University of Antwerpen (Belgium) for their helpful comments and suggestions at different stages of the development of this work.
