||Xunzi was the influential philosopher of China's Warring States period (479–221 B.C.E.). He considered himself a follower of Confucius, and his philosophy belongs to the tradition of what might be called classical Confucianism. It certainly took part in consolidating the doctrine. Xunzi's significance has often been underestimated, especially in favour of Mencius. Xunzi system addresses topics ranging from economic and military policy, through the justification of traditional authority and institutions, to action theory and the philosophy of language.
