De Oratore is a dialogue written by Cicero in 55 BCE. Amidst the moral and political decadence of the state, Cicero wrote De Oratore to describe the ideal orator and imagine him as a moral guide of the state. He did not intend De Oratore as merely a treatise on rhetoric, but went beyond mere technique to make several references to philosophical principles. Cicero believed that the power of persuasion—the ability to verbally manipulate opinion in crucial political decisions—was a key issue and that in the hands of an unprincipled orator, this power would endanger the entire community.
