Prudence has long been an important topic for rhetorical theorists and its place in intellectual history is becoming increasingly well documented. This essay develops a conception of prudence as an ideological construct, a term crafted in the history of its public usages to govern the relationship between common sense and political action as enacted in the name of historically situated social actors. From this perspective, prudence represents the recursive interaction between a rhetoric of judgment and the grounds on which that (...) rhetoric is evaluated by a historically particular community of arguers. A case study of the 1991 U.S. Senate debate regarding the authorization of offensive military action in the Persian Gulf illustrates how competing standards of prudential judgment are crafted and evaluated in discursive controversy.
