What do these two creatures know？
“Since the cicada and the dove are small，they know nothing about the large.”—Translator
Small knowledge is not to be compared with the great nor a short life to a long one.How do we know that this is so？The morning mushroom knows not the end and the beginning of a month.The chrysalis knows not the alternation of spring and autumn.These are instances of short life.In the south of the Chu（楚）state，there is Ming-ling [1]（冥灵），whose spring is five hundred years，and whose autumn is equally long.In high antiquity，there was Ta-chun（大椿），whose spring was eight hundred years，and whose autumn was equally long.P’eng Tsu（彭祖）was the one specially renowned until the present day for his length of life.If all men were to match him，would they not be miserable？
