Rhetoric
Its origin was in Ancient Greece of the 5th century. They made their decisions by speaking for or against proposals in a public place. Also, speeches were made when a person was accused of a serious crime before the magistrates. Because rhetoric was so important to them, the Greeks and Romans wrote about how to be a good rhetorician. This is sometimes called 'secondary rhetoric'. It is a technique which can be taught, and used in writing. An early example is Plato, who wrote his works in the form of dialogues. Each question raised is discussed between two characters. In the ancient world, the Romans, who were much influenced by the ancient Greeks, also used the same methods for decision-making. Cicero was one of their famous orators. In their case, the debates did not involve all citizens, just the Roman Senate or the courts.
