In researching successful examples of resistance for this book, I came across many iterations of the space of appearance. I’m struck by one thing that hasn’t changed: while certainly supported by other forms of communication, the space of appearance is still so often a space of physical appearance. The history of collective action—from artistic movements to political activism—is still one of in-person meetings in houses, in squats, in churches, in bars, in cafés, in parks. In these federated spaces of appearance, disagreements and debates were not triggers that shut the whole discussion down, but rather an integral part of group deliberation, and they played out in a field of mutual responsibility and respect. In turn, those groups kept in touch with other groups, who kept in touch with still other groups, sometimes spanning the country—as in the case of groups like the Student Nonviolent Coordinating Committee or the successive layers of organized labor.
