Challenging the Tradition of Rhetoric...
For just a start, see the critiques of traditional rhetoric of James Berlin
(especially from the bibliography
compiled by Victor Vitanza).
For a a significant critique of Aristotle and the implications of his rhetoric, see Jasper Neel: Aristotle's Voice: Theory and Writing in America. Carbondale: Southern Illinois UP, 1995. One might also look to the work of Theodor Adorno and Max Horkheimer for related analyses of greek cultural context and texts as fundamentally connected to Western Ideologies of dominance and, specifically, capitalism.
