This article argues that Habermas’s formal-pragmatics are better understood as a set of weak-universal dispositions susceptible to erosion over the course of a lifetime, if exposed to continual “disappointing” communicative experiences. Habermas’s rational-reconstructive project to explicate the intuitive rule-consciousness held by competent speakers retains immense theoretical value for analyzing both partisan and mass political discourse, if his emphasis on isolated speech situations is supplemented with a logic of communicative memory better accounting for how disagreement antecedes discourse on the formal-pragmatic register. (...) I argue that Habermas’s concept of the “lifeworld” contains untapped theoretical resources for thinking about the formal-pragmatic consequences of accumulated partisan experiences; namely, how such experiences lead inter-partisan actors to jettison mutual imputations of communicative accountability. I conclude by offering revisions to Habermas’s discourse ethics. Rapport-building intended to alleviate the negative effects of prior accumulated partisan experiences is first necessary if a norm is to enjoy real justification. (shrink)
