From 《
尚书·
泰誓中》 (quoted also by Mencius in 《
孟子·
万章上》):
天视自我民视,
天听自我民听 (Heaven sees through what our people see; Heaven hears through what our people hear). One of the earliest and most important classical formulations of popular legitimacy — the ancient basis for the Mandate of Heaven (
天命) theory, in which a dynasty that loses popular support has lost Heaven's favor.
