Book excerpt: In Motorbike People: Power and Politics on Rwandan Streets, Will Rollason examines the relationship between power and culture. Rollason looks at what social scientists gain—and lose—by abandoning the assumption that power is a universal feature of human social life. Through an ethnographic account of the lives and livelihoods of motorcycle taxi drivers in Kigali, Rwanda, Rollason depicts how forms of personhood can sit uneasily with conventional accounts of power relationships. From the motorcyclists’ everyday dealings with the police and each another to the regulation of their businesses at large and the Rwandan constitution, Rollason depicts the need for varied concepts of power. By allowing concepts of power to proliferate, the social sciences lose the political capacity to engage in questions of justice and make common cause with the oppressed, but gain the ability to rethink what it means to act politically and meet the challenges of a swiftly changing world. This work is recommended for students and scholars of the social sciences.
