Translingual scholarship emphasizes the temporal dimensions of language use, and frame language practices as emergent phenomena shaped by repertories of discursive activities sedimented through prior experience. This essay adapts Gee’s concept of lifeworld Discourse in order to theorize (1) how Discourse competencies are cultivated through the sedimentation of discourse practices over time, and (2) how actors occupy thresholds or dwell on borders while they draw on repertoires sedimented through prior experience in response to emergent rhetorical situations. I activate the lifeworld Discourse conceptual framework in an analytical approach that I call a Discourse genealogy in order to trace out the palimpsestic emergence and blending of Discursive competencies throughout labor and community organizer César Chávez’s life. The argument focuses on the archival record of Chávez’s literacy practices in order to understand his emergent lifeworld Discourses from birth in 1927 through the late 1950s, up to the point at which he began to organize the migrant farmworkers under the auspices of the Community Service Organization in Oxnard, California (1957-8). Using textual analysis of Chávez’s writings and oral history records, the following essay shows how one thread of Chávez’s lifeworld Discourse – responding to social injustice – binds together a number of Chávez’s varied Discursive repertoires. My central argument is that when we occupy thresholds that connect Discourses, our repertoires of practice may be blended with new practices to form emergent potentials for responding to rhetorical situations. The thread of repertoires sedimented throughout a lifetime bind together the various social Discourses we encounter and engage with in our public lives.

This essay argues that literacy actors compose agency through the embodied practice of literacies in combination with self-aware feedback loops. The argument brings together recent conversations on agency, embodiment, and cognition in composition studies, neuroscience, and the humanities to develop the concept of discursive readiness potential. Discursive readiness potential refers to one’s embodied agency and accounts for the range of possible actions available to an actor on the basis of her or his past experiences. Furthermore, discursive readiness potential points to one’s capacity to navigate a field of potential literate practices into one actualized action. As such, the essay supports a renewed call for research on agency and embodied cognition in composition studies by outlining discursive readiness potential as a flexible process model for understanding how agents act in emergent discursive situations.
