Quote by Aristophanes (450 BC-388 BC)

• This is what extremely grieves us, that a man who never fought
  Should contrive our fees to pilfer, on who for his native land
  Never to this day had oar, or lance, or blister in his hand.

• Under every stone lurks a politician.

• Let each man exercise the art he knows.

• Men of sense often learn from their enemies. It is from their foes, not their friends, that cities learn the lesson of building high walls and ships of war . . .

• The wise learn many things from their enemies.

• You have all the characteristics of a popular politician: a horrible voice, bad breeding, and a vulgar manner.
