"鬼谷子" by active 4th century B.C. Guiguzi is a collection of ancient Chinese texts compiled between the late Warring States period and the end of the Han dynasty. This work explores techniques of rhetoric and persuasion, teaching strategies where influence remains hidden and decisions appear self-made. Originally associated with the School of Diplomacy, it later joined the Daoist canon. The text emphasizes silent observation and subtle persuasion over coercion, offering principles sometimes compared to Machiavelli's teachings in Western philosophy.
