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?
A. civil rights
B. equality before the law
C. separation of powers
D. citizen responsibilities
