Mencius 7B.5: rules can be taught, skill cannot
Mencius says craftsmen can hand over standards, but not mastery itself. Learning begins with measure, yet skill must grow inside the learner.
孟子曰:「梓匠輪輿,能與人規矩,不能使人巧。」
Mencius said, 'A carpenter or a carriage-maker may give a man the circle and square, but cannot make him skilful in the use of them.'

Central question
Why does Mencius say craftsmen can give rules to others but cannot make them skillful?
Direct answer
Because standards, methods, and tools are teachable, but genuine skill and judgment must be formed by the learner's own repeated practice.
First principle
Education is easily mistaken for information transfer. The harder work is turning an outer rule into an inner power.
Why it matters
This passage serves searches around learning, standards, skill, and the difference between teaching and mastery.
