Rhetoric A–Z
What rhetoric is, where its concepts come from, and how they still shape the way we speak and listen. Short introductions written by a professor of rhetoric, for anyone who wants to understand it properly.
What is rhetoric?
The oldest surviving use of the word is in Plato’s Gorgias, where rhetoric is the ability to persuade. Aristotle saw the problem: no art can guarantee persuasion, because every situation is singular. So he redefined rhetoric as the capacity to observe, theōrēsai, what may persuade in each case.
Rhetoric, in other words, is a way of seeing: seeing through language.
