How was Athens a civilized and advanced society?

The citizens of Athens decided matters of state in the Assembly of the People, the principle organ of Athen’s democracy.  The Athenian democracy provided a number of governmental resources to its population in order to encourage participation in the democratic process.  Many governmental posts in classical Athens were chosen by lot, in an attempt to discourage corruption and patronage.  The Athenian elite lived relatively modestly, and wealth and land were not concentrated in the hands of the few, but rather distributed fairly evenly across the upper classes.  Thetes occupied the lowest rung of Athenian society, but were granted the right to hold public office during the reforms of Ephialtes and Pericles.
