This speech discussing the Athenian government was delivered by Pericles in the fifth century BCE.Our constitution does not copy the laws of neighboring states; we are rather a pattern to others than imitators ourselves. Its administration favors the many instead of the few; this is why it is called a democracy. If we look to the laws, they afford equal justice to all in their private differences; if to social standing, advancement in public life falls to reputation for capacity, class considerations not being allowed to interfere with merit; nor again does poverty bar the way; if a man is able to serve the state, he is not hindered by the obscurity of his condition.Which principle did Pericles discuss in this speech?
