Erik Rietveld is a Socrates Professor in Philosophy at the University of Twente and the University of Amsterdam (Amsterdam UMC, Department of Psychiatry). Earlier, he was a Fellow in Philosophy at Harvard University. Rietveld’s fundamental research on the philosophy of embodied cognition has impact in a wide variety of fields: psychiatry, ecological psychology, theoretical neurobiology, deep brain stimulation, sustainability, and the arts. Together with his brother Ronald Rietveld he founded the multidisciplinary and experimental collective for visual art, architecture and philosophy RAAAF in 2006. They were responsible for Vacant NL, the successful Dutch contribution to the Venice Biennale 2010. RAAAF’s art installation The End of Sitting materialized a vision on the office of the future, in which chairs are replaced by non-sitting positions to encourage more active life-styles. Erik Rietveld is a member of the Society of Arts of the Royal Netherlands Academy of Arts and Sciences (KNAW). The title of Rietveld’s inaugural lecture was The Affordances of Art for Making Technologies (2019). Other philosophical publications include Situated Normativity (2008) and The Landscape of Affordances (2020), co-authored with Ronald Rietveld. His article A Rich Landscape of Affordances (2014), co-authored with Julian Kiverstein, is the most read and cited article in Ecological Psychology. In 2021 Rietveld was awarded a prestigious VICI grant by the Netherlands Organisation for Scientific Research (NWO) for his new five-year research project Change-Ability on coordinated collective behavioral change in a rapidly changing world. In 2023 Erik Rietveld and Ronald Rietveld were awarded the Global Award for Sustainable Architecture, under the patronage of UNESCO for the experimental, art-based approach.
