In this article, the authors (re)think writing as an ethical endeavor to explore and to cultivate more inclusive orientations for writing research and teaching. Situated in posthumanist scholarship on intra-activity, trans-corporeality, and translingual assemblages, they provide data-theory encounters that resist the privileging of alphabetic print, standardized written English approaches to writing pedagogies that have detached writers from the contextual doing/being/feeling demanded of composing-with-all-bodies. Data in the article are drawn from three separate research projects. Diffractively reading data through posthumanist theoretical concepts, the authors highlight the tensions and insights produced from their analysis to provoke an ethico-onto-epistemological shift in writing studies and classroom pedagogies, and to enliven the ethical work of exploring and cultivating more inclusive orientations to writing research and teaching.
