Rhetorical scholarship typically conceptualizes an event of dissention as a break in a dominant discourse. More recent scholarship drawing upon rhetorical ecologies and new materialisms suggests, however, that analyses of events of dissention would benefit from greater consideration of bodies and environments. Things can also initiate “fissures of unreason” through their material presences and encounters with their physical dynamics, un/healthful effects, or felt forces. An analysis of the 2014 Lion Rock pro-democracy protest in Hong Kong encourages detailed thinking about how material capacities enable protest rhetorics. Ultimately, I argue that the event at Lion Rock is best characterized as a theatrical event of dissention, which demonstrates the integral role of the material in bringing about “unruly rhetorics.”
