Plato's Philosophy and Main Ideals
Plato believed that democracy was not a good system of government. He thought that rule by people wasn't fair or reasonable. One of Plato's writings (Republic) he described how he would run the government. At the top were philosophers, then warriors, and the last group was made up of the rest of the people. Plato thought that men and women are equal, and that they should be able to get the same education and the same job opportunities.
