1. You, maybe, know that people learned rhetoric to participate in political life and defend yourself in court. Once, Cicero musted to lose a dispute in court, because his opponent was from an influential clan. The win could take away his life because people from this clan could kill him. After the loss, he moved to Greece and continued learning rhetoric there.
2. Marcus Fabius Quintilianus was a Roman educator and rhetorician, lived in the first century of AD. He was a founder of a rhetoric school. The goal of the school was to graduate good average rhetoricians. Why "average"? Once upon a time, philosophies discussed what is the ideal rhetorician. Quintilianus thought that nobody can't become the ideal rhetorician, because "all great rhetorician was in the past". So, Cicero thought that the ideal rhetorician will become someday.
Students worked in group and interacted with each other. He convinced that it was the ideal conditions for becoming a good rhetorician.
Cicero was convinced that only practice can make you a good rhetorician.
I wonder what they lived two thousand ago. They were so sensible, we still use their theories and works.
Also, I love students of the Quintilianus's school interacted with each other. I think that our "modern" education misses this part. Modern students don't work at group and interact only with the teacher in education process.
Also, that's funny that people always was afraid of influential people, because they are more powerful and have more money.
