 Rhetorical studies of speakers, audiences, their purposes, and their social contexts were revived in twentieth century argumentation theory by Chaim Perelman and Lucie Olbrechts-Tyteca (1958 [1969]). Perelman, writing on his own, advocates that instead of appealing to “the rational” as a standard for argumentation, scholars should consider a “reasonable” person in terms of the standards of a particular community (1977 [1982]).
