Practicing New Worlds explores how principles of emergence, adaptation, iteration, resilience, transformation, interdependence, decentralization, and fractalization can shape organizing toward a world without the violence of surveillance, police, prisons, jails, or cages of any kind, in which we collectively have everything we need to survive and thrive. Drawing on decades of experience as an abolitionist organizer, policy advocate, and litigator in movements for racial, gender, economic, and environmental justice and the principles articulated by adrienne maree brown in Emergent Strategy: Shaping Change, Changing Worlds, Ritchie invites us to think beyond traditional legislative and policy change to create more possibilities for survival and resistance in the midst of the ongoing catastrophes of racial capitalism--and the cataclysms to come. Rooted in analysis of current abolitionist practices and interviews with on-the-ground organizers resisting state violence, building networks to support people in need of abortion care, and nurturing organizations and convergences that can grow transformative cities and movements, Practicing New Worlds takes listeners on a journey of learning, unlearning, experimentation, and imagination to dream the worlds we long for into being.
