Docere
Docere is a Latin word that means to instruct, teach, or point out. Cicero first introduced this term in his book De Oratore. Cicero wrote this book in 55 BC as a dialogue to describe the ideal speaker and imagine him as a moral guidance of the state. He suggested that there are three duties or goals of rhetoric. He described these as 'to teach, to delight and to move' (docere/probare, delectare/conciliare, movere/flectere) Cicero breaks down the term Docere further and summarizes that 'to teach' means to provide truth through rational argument and statement of facts.
