Protests abound in contemporary political life, including in the United States: One-fifth of Americans reported having participated in a political protest between early 2016 and early 2018. Protest and Dissent examines the justification, strategy, and limits of mass demonstrations and other forms of resistance, drawing, in the distinctive NOMOS fashion, from political science, philosophy, and law. Its linked chapters are informed by African American political thought, Gandhian nonviolence, the history of the Civil Rights Movement, and the dynamics of recent social movements. In the ten chapters of Protest and Dissent, the authors challenge their fellow contributors and readers to reimagine the boundaries between civil and uncivil disagreement, between political reform and radical transformation, and between democratic ends and means. The volume has three parts. The first takes up the justification of civil and uncivil disobedience; the second addresses the strategic logic of political protest; and the third analyzes the democratic implications of protest and dissent, including in comparative perspective.
