The Dialectic is a rhetoric method of analyzing and breaking down arguments by using detailed questions. The opponents in this process are generally called interlocutors. Plato’s method of argumentation is often hailed as an effective rhetorical strategy in a spoken debate, but its emphasis on verbal discussion over written makes it difficult to translate into writing centered rhetoric courses.
Thrasymachus is an interlocutor from Plato’s The Republic , and he represents a category of rhetoricians known as the sophists. Sophists assert that the most rhetorically convincing argument is greater than a lackluster correct argument—in other words, flash over accuracy.
