Shen Dao (c. 350 – c. 275 BC) was a Chinese philosopher and writer. He was a Chinese Legalist theoretician most remembered for his influence on Han Fei with regards to the concept of shi (勢; 'power', ' potential', circumstantial advantage or authority), but most of his book concerns the concept of fa (administrative methods and standards) more commonly shared by his school. Compared with western schools, Shen Dao considered laws that are not good "still preferable to having no laws at all."[1]
Usually referred to as "Shenzi" (慎子 'Master Shen') for his writings, very little is known of Shen Dao's life. An itinerant philosopher from the state of Zhao, he was probably born about 350 BC, travelling to the city of Linzi (modern Zibo in Shandong) in 300 BC to become a member of the Jixia Academy. He probably left Linzi after its capture by the state of Yan in 285 BC. Speculatively, he might have moved to the Han kingdom and absorbed the Legalist traditions there. He died roughly 10 years later.[2][3]
