This essay investigates ethical issues inherent in service learning through considering the dynamics of generative ethos, Jim Corder’s term for a process of becoming through writing. By closely examining the ethical issues involved in Phyllis Ryder’s Rhetorics for Community Action: Public Writing and Writing Publics and tracing parallels between students’ experiences in Ryder’s course and Corder’s own idea of generative ethos, this essay argues that generative ethos can offer a productive lens into understanding how students navigate the ethically tenuous territory of service learning.
