Mohism or Moism (aka. Mohist School of Logic) was an ancient Chinese philosophy of logic, rational thought and science developed by the academic scholars who studied under the ancient Chinese philosopher Mozi (c. 470 BC–c. 391 BC). It evolved at about the same time as Confucianism, Taoism and Legalism, and was one of the four main philosophic schools from around 770–221 BC (during the Spring and Autumn and Warring States periods). During that time, Mohism was seen as a major rival to Confucianism. The administrative thought of Mohism was absorbed by Chinese Legalism and its books were later merged into the Taoist canon, all but disappearing as an independent school of thought.
