Chapter 33, Part 4C - Chuang Tzu

Because a creature that is without knowledge does not face the perils that come from trying to set oneself up, the entanglements that come from relying upon knowledge. In motion or in stillness, he never departs from reason - in this way he lives out his years without winning praise.

Therefore Shen Tao said, "Let me become like those creatures without knowledge, that is enough. Such creatures have no use for the worthies or the sages. Clod-like, they never lose the Way." The great and eminent men would get together and laugh at him, saying, "The teachings of Shen Tao are not rules for the living but ideals for a dead man. No wonder he is looked on as peculiar!"
