Hsün Tzu (Xunzi, c. 312-230 BCE)
“If men have no teachers to instruct them, they will be inclined towards evil and not upright; and if they have no ritual principles to guide them, they will be perverse and violent and lack order.”
- From Hsün Tzu’s Basic Writings (section 23, “Man’s Nature Is Evil”), translated by Burton Watson (Columbia University Press, 1963, 1996).
