click EXPAND for details on Nathan the Wise and the "parable of the rings"

• • • a play about Nathan, a Jewish merchant who meets Saladin the Great, the Ottoman sultan and thus a core Islamic leader
    • Saladin asks Nathan which of the Abrahamic religions is the "true religion"
      • Abrahamic religions are Judaism, Christianity and Islam (in order of historical appearance)
    • Nathan avoids the question trap by answering with the "parable of the ring"
      • = a story about a magical ring that empowers the bearer God's approval ("pleasing to God")
        • i.e., the bearer's religion is the "true religion"
      • it is passed on by generation, until a father can't decide which of three sons to give it to
        • so he creates two exact copies and gives each son a ring
      • afterwards, the sons argue over who owns the actual ring
      • they take their dispute to a wise man who tells them
        • that perhaps all three rings are replicas, they cannot know
        • therefore, if each acts in such a way as God will be pleased, it would show that each ring has the magical power
        • i.e., God doesn't judge by one's religion but by one's actions

Isaac Newton

• Principio Mathematica
• launched idea of a divinely-ordered universe understandable by mathematics

Voltaire

• Candide: satire on Englightenment thought "best of all possible worlds" << to do
