Delves into the rhetorical work of elective single mothers (ESMs) in the late twentieth- and early twenty-first centuries as they sought--and continue to seek--to legitimize their maternal identities and family formations Scholars of rhetoric have largely overlooked the inherent rhetoricity of family. In The Case for Single Motherhood, Katherine Mack posits family as a central concern of rhetorical studies by reflecting on how language is used by single mothers who seek to reenvision the personal, social, and political meanings of family. Drawing on intersectional and rhetorical theories, Mack demonstrates how the category of elective single motherhood emerged in response to the historically differential treatment of "unwed mothers" along racial and class lines. Through her readings of a range of self-sponsored ESM texts--guidebooks, memoirs, and interactive digital media written by and primarily for other ESMs--and from her perspective as an elective single mother herself, Mack evaluates the rhetorical power, as well as the exclusions and hierarchies, that the ESM label effects. She analyzes how ESMs envision motherhood, visions that entail their musings about who can and should mother. Ultimately, Mack offers women who are considering nonnormative paths to motherhood a way to affirm their maternal identities and paths without disparaging others'. Scholars in the fields of rhetoric and feminist rhetorical studies will find in this volume an illuminating perspective on the rhetorical power of self-sponsored texts in particular. Crafting a methodology to identify and evaluate the goals and effects of legitimacy work and selecting sources that bring academic attention to varied genres of self-sponsored writings, Mack paves the way for future rhetorical studies of motherhood and family.
