There was once a mighty king, Nathan the Wise one, who had a magic ring. Whoever possessed this ring would be rich, wise & powerful. King Nathan also had three sons. He knew that when he died, his sons would quarrel over possession of the ring. So, he had two duplicate, but non-magic rings forged. On his death bed, he gave a ring to each of his sons, and so died.
His sons spent the rest of their lives quarreling over who was the richest, wisest, and most powerful.
The moral of the story is: If you believe that you have the truth, act like it.
