The present paper analyses the birth of the rhetorical art among the Greeks, with special attention to the Rhetoric of Aristotle. Its aims are twofold: to examine concepts, thereby reformulating the teachings that the Greek philosopher presents in his work, and to demonstrate the importance of Aristotelian reflections to education. Although the philosopher is not committed to a didactic purpose, the contributions present in the Rhetoric may have considerable importance to the field of teaching. This work is divided into four main parts. The first chapter contains a general introduction to the problem; the second retrieves the history of rhetoric in ancient Greece focusing on the similarities and differences between Aristotle and other philosophers and sophists; the third includes a selective examination of Aristotle s Rhetoric.; finally, the fourth chapter is an effort to associate Aristotelian concepts with central themes on the field of education.
