This book is one part of a vast, ongoing conversation about who we are, what powers we have, and what we can do with them, and it comes out of readings, conversations, friendships, and organizing with many brilliant, heroic, and kind people over the years, often people who drew me deeper into their part of the world and the work. Especially my brother David; political theorist, idealist, documenter of horizontalidad, dear friend, and inspiration Marina Sitrin; Bob Fulkerson of the Progressive Leadership Alliance of Nevada and Kaitlin Backlund and Jo Anne Garret (1925–2013), whose friendship has been the most direct reward for my years of environmental work in that state; Utah environmental writer Chip Ward; Oklahoma indigenous organizer and longtime friend Pam Kingfisher; John Jordan of Reclaim the Streets in London in the 1990s, now a climate activist in France; nonviolence theorist and writer Jonathan Schell, much missed since his untimely death in 2014; Stephen Zunes and Erica Chenoweth, great and hopeful theorists of nonviolence now; my friends at 350.org Bill McKibben, Payal Parekh, Jamie Henn, Anna Goldstein, and May Boeve; all the great activists of Occupy Wall Street in its many manifestations, especially the brilliant Astra Taylor, now of Strike Debt, who’s also a beloved friend; musician, physician, and everyday co-conspirator Rupa Marya; feminist and friend Elena Acevedo Dalcourt and the many feminists whose online discourse has helped refine and shape my ideas about gender and justice; Father Louis Vitale; Zenkei Blanche Hartman; Guillermo Gomez-Pena; David Graeber; Barry Lopez and Terry Tempest Williams, whose depth in writing and speaking inspired me to go deeper as this book was taking shape; my amazing activist cousins once removed, Mary Solnit Clarke (1916–1997) and June Solnit Sale, founding members of Women Strike for Peace, the latter in her seventh decade of human rights activism; my comrade in hope Sam Green; Brad Erickson, an important early influence on my understanding of indigenous politics; Antonia Juhasz; Maya Gallus; Genine Lentine; Thomas Evans; Gustavo Esteva; Paul Yamazaki; Patrick Marks and Gent Sturgeon; and so many more people that this list could never be completed.
