Tao Te Ching

One on tiptoe is not steady; one astride makes no advance. Seff-displayers are not enlightened, self-asserters lack distinction,  self-approvers have no merit, and self-seekers stunt their lives.

Before Reason this is like surfeit of food; it is like a wen on the body with which people are apt to be disgusted. Therefore the man of reason will not indulge in it.
