" True moderation in the defence of political liberties is indeed a difficult thing: pretending to want fair shares for all, every man raises himself by depressing his neighbour; our anxiety to avoid oppression leads us to practice it ourselves; the injustice we repel, we visit in turn upon others, as if there were no choice except either to do it or to suffer it. "
― Livy , The History of Rome, Books 1-5: The Early History of Rome
