A priest (神父) lived with his small white cat. One day, the cat climbed up a tree and was afraid to come down. The priest called its name and gave it its favourite drink, warm milk, but the cat still didn't come down. So the priest decided to tie rope (栓一根绳子) between his car and the tree. He thought as he drove, the tree would bend down (弯曲) and he could get the cat. He did so. But he drove too far, and the rope broke (断).

    The tree went "boing!" and the cat went through the air. The priest couldn't see it. He felt terrible. He walked around and asked people if they'd seen his cat. But nobody had seen it. At last, he said, "God (上帝), I just give this cat to your keeping."

    A few days later, he met one of his friends in a shop. He saw cat food in her shopping bag. This woman didn't like cats and everyone knew it, so he asked her in surprise, "Why are you buying cat food?"

    She answered, "My little girl always wanted a cat, but I didn't agree. Then a few days ago, she asked again. I told her if God gave her a cat, she could keep it. She went out of the house and said something to the sky. Then suddenly a cat flew out of the blue sky and landed in front of her. "

    The priest smiled and said, "How lucky your little girl is!" Then he went on shopping.

材料一：养心莫善于寡欲；其为人也寡欲，虽有不存焉者，寡矣；其为人也多欲，虽有存焉者，寡矣。

——《孟子·尽心下》

材料二：故圣人之制民，使之有欲，不得过节；使之敦朴，不得无欲；无欲有欲，各得以足，而君道得矣。

——董仲舒《春秋繁露·保位权》

材料三：欲是情发出来底。心如水，性犹水之静，情则水之流，欲则水之波澜，但波澜有好底，有不好底。欲之好底，如我欲仁之类；不好底，则一向奔驰出去，若波涛翻滚。大段不好底欲，则灭却天理。如水之壅决，无所不害。

——《朱子语类》卷5

材料四：有生之初，人各自私也，人各自利也……夫以千万倍之勤劳，而己又不享其利，必非天下之人情所欲居也……后之为人君者不然，以为天下利害之权皆出于我，我以天下之利尽归于己，以天下之害尽归于人，亦无不可；使天下之人不敢自私，不敢自利，以我之大私为天下之公。

——黄宗羲《明夷待访录·原君》
