literature discussing rhetoric is mainly concerned with rhetoric per s
e its structure, and the categorization of arguments by kind. Rarely d
o rhetorical studies examine the actual effects on audiences, and audi
tors' reactions. On the other hand, sociological studies of scientific
controversies look at rhetoric - or argumentation - in action, but wi
th few references to rhetorical studies.The purpose of this paper is t
o integrate rhetorical studies into the sociology of technology in ord
er to integrate the concept of action into discourse analysis. I inten
d to show how the use of discourse to enroll actors in a health techno
logy is intimately linked to action. I deconstruct the promoters' stra
tegy into two discursive components - the utility component and the fe
ar-reduction component - to show how the rhetoric of expectations (uti
lity) and representations (fear) contingently shape the fate of a tech
nology.
