《庄子·外篇·天道》
你行为暂时有所强制，一旦行动就象箭发弩机，你明察而又精审，自持智巧而外露骄恣之态，凡此种种都不能看作是人的真实本性。
动而持，发也机，察而审，知巧而睹于泰，凡以为不信。边竟有人焉，其名为窃。 
When you act, you are quick as a released arrow. When you look, you are piercing and acute. You are certainly clever and full of self-importance. Yet such things cannot be regarded as the Way of man.
