What did the Athenians call the administration in their policy? Why did they think this was the best management?

This type of government was considered the best, as it allowed the broad masses to influence the politics of Athens. The opinion of each person is important.
Later, Thomas Hobbes called the state Lefiathan. From his point of view, this beast must be kept in check.
Athenian democracy was up to the task. There was no political repression, the people were free in their statements and actions.
