The rhetorical tradition, Michelle Ballif asserts, is based on the systematic exclusion of sophistry. In keeping with Aristotle’s prescription, rhetoric continues to be a counterpart to dialectic, a handmaiden to the pursuit of truth—even if that truth is merely probable.

According to Ballif, this search for truth manifests itself among current rhetoric and composition scholars in the form of an assumption that language is primarily communicative (i.e., that language can represent truth more or less faithfully). Ballif shows how invested we are in the notion of truth, in the idea that language represents truth, and in the assumption that the speaking/writing subject has, or should have, some essential relation to truth.

Provocatively, Ballif questions why the profession wants to retain these beliefs in the face of vociferous arguments from "new rhetorics" that the discipline no longer posits a foundational self or truth, and in the face of the poststructuralist critique, which has demonstrated that founding truth is always accomplished by first positing and then negating an “other.” As an alternative to this negative and violent rhetorical process, Ballif suggests a turn to sophistry as embodied in the figure of Woman, one with the power to seduce us (literally, to lead astray) from our truth and our demand for it.

This figuration of Woman, however, is not the dialectical other used to sustain the identity and privilege of Man. On the contrary, this Woman is an Other Woman: A Third Woman as a Third Sophistic practice that escapes Plato’s binary (philosophic rhetoric vs. sophistry) and renders the distinction between truth and deception incalculable. Ballif examines three figurations of the Third Woman as Third Sophistic as offered by Gorgias, Friedrich Nietzsche, and Jean Baudrillard.
