塞翁失馬 or Sāi Wēng lost his horse

Sāi Wēng lived on the border and he raised horses for a living. One day, he lost one of his prized horses. After hearing of the misfortune, his neighbor felt sorry for him and came to comfort him. But Sāi Wēng simply asked, “How could we know it is not a good thing for me?”

After a while, the lost horse returned and with another beautiful horse. The neighbor came over again and congratulated Sāi Wēng on his good fortune. But Sāi Wēng simply asked, “How could we know it is not a bad thing for me?”

One day, his son went out for a ride with the new horse. He was violently thrown from the horse and broke his leg. The neighbors once again expressed their condolences to Sāi Wēng, but Sāi Wēng simply said, “How could we know it is not a good thing for me?” 

One year later, the Emperor’s army arrived at the village to recruit all able-bodied men to fight in the war. Because of his injury, Sāi Wēng’s son could not go off to war, and was spared from certain death.

there's nothing new in human nature

There's nothing new in human nature. The only thing that changes are the names we give things. If you want to understand the twentieth century, read the lives of the Roman emperors, all the way from Claudius to Constantine.... And go back to old Hammurabi, the Babylonian emperor. Why, he had laws that covered everything, adultery and murder and divorce, everything.

Those people had the same troubles as we have now. Men don't change. The only thing new in the world is the history you don't know.
