Xun Kuang was born in the year 310 BCE within the state of Zhao, which is located in modern-day Shanxi Province. This birth occurred during the Warring States period, an era defined by over a century of relentless warfare and political fragmentation.
Between 297 and 295 BCE, Xunzi traveled to the northeastern state of Qi to attend the Jixia Academy established by King Xuan. He studied under scholars like Zou Yan, Tian Pian, and Chunyu Kun while mastering the art of shuo, a formal method of persuasion used to advise rulers.
Chapter twenty-three of his collected works titled Human Nature is Evil states that Xun Kuang argued humanity's inborn tendencies were evil rather than good. He claimed ethical norms existed solely to rectify these natural flaws through education and ritual to transform base nature into virtue.
Han Fei and Li Si emerged as the most famous pupils of Xunzi during his teaching years at Jixia. Li Si eventually became Chancellor of the Qin dynasty after unifying China, though their Legalist sentiments often clashed with Xunzi's Confucian philosophy.
Xunzi retired to Lanling where he lived until his death sometime after 219 BCE following the assassination of Lord Chunshen in 238 BCE. This position ended abruptly when Lord Chunshen was assassinated by a court rival in 238 BCE.
