Chapter 17, Part 4C - Chuang Tzu

The Lord of the River said, "Whether they are external to things or internal, I do not understand how we come to have these distinctions of noble and mean or of great and small."

Jo of the North Sea said, "From the point of view of the Way, things have no nobility or meanness. From the point of view of things themselves, each regards itself as noble and other things as mean. From the point of view of common opinion, nobility and meanness are not determined by the individual himself.

"From the point of view of differences, if we regard a thing as big because there is a certain bigness to it, then among all the ten thousand things there are none that are not big. If we regard a thing as small because there is a certain smallness to it, then among the ten thousand things there are none that are not small. If we know that heaven and earth are tiny grains and the tip of a hair is a range of mountains, then we have perceived the law of difference.
