Peter Garrett's 1995 paper in the Groupwork Journal represents a foundational document for prison dialogue practice. Writing years before the Virginia Department of Corrections work that would later bring international attention, Garrett describes early experiments bringing Bohmian dialogue into maximum-security settings in the UK. The paper addresses practical challenges that remain relevant today: how to establish genuine dialogue within institutional power structures, what happens when men serving life sentences encounter unfamiliar conversational norms, and how facilitators navigate the tension between security requirements and authentic exchange. Garrett draws on David Bohm's theoretical framework while grounding every insight in concrete prison experience. He examines group dynamics unique to incarcerated populations and considers what transformation means for people facing decades behind bars. For practitioners interested in criminal justice applications, this paper offers both historical perspective and enduring practical wisdom from someone who helped establish the field.
