This article theorizes infrastructures and their components as rhetorical objects for analysis and persuasive use. Though the term infrastructure has been applied broadly to several studies in the social sciences, writing, technical communication, and technology studies, infrastructures have yet to be systematically theorized as an active persuasive consideration for those engaging in communicative practice. This article makes a case for a taxonomic theoretical understanding and conceptualization of infrastructure that may lead to new methodological developments in future research. This theory builds from theories of infrastructures as relational networks of social interaction around objects. The article aims to assist the persuasive endeavors of those engaged in communicative practice in infrastructural settings.
