With the publication in 2002 of Martin Heidegger’s summer semester 1924 lectures, “Basic Concepts of Aristotelian Philosophy,” a major new star appeared in the constellation that is twentieth-century rhetoric. Since then, a growing secondary literature has emerged. This article organizes that literature as a series of specifications closing in on Heidegger’s critical conception of rhetoric as potentially a hermeneutic of the everydayness of being with others, and it claims that our understanding of this everydayness will remain flat or partial until we situate the concept in the sequence of Heidegger’s thought in the 1920s. If we work through pre-1924, 1924, and post-1924 periods, it becomes clear that there are religious, modal, and sophistic contexts for Heidegger’s evolving conceptualization of everydayness. The concept of everydayness that emerges is disheveled but rich. The article concludes by suggesting that only faint echoes of these potent rhetorical trajectories can be discerned in the late Heidegger.
