Mencius ( MEN-shee-əs); born Mèng Kē (Chinese: 孟軻); or Mèngzǐ (Chinese: 孟子; 372–289 BC) was a Chinese Confucian philosopher who has often been described as the "second Sage", that is, after only Confucius himself. He is part of Confucius' fourth generation of disciples. Mencius inherited Confucius' ideology and developed it further. Living during the Warring States period, he is said to have spent much of his life travelling around the states offering counsel to different rulers. Conversations with these rulers form the basis of the Mencius, which would later be canonised as a Confucian classic.
