  Our primary source for the thought of Mozi and his followers is a corpus of anonymously authored texts collected into a book called the Mozi. Other, less direct sources include anecdotes and comments about the Mohists preserved in early texts such as the Lushi Chunqiu, Hanfeizi, Zhuangzi, and Huainanzi and criticisms of them by two of their major opponents, the Confucians Mencius (ca. 372–289 BCE) and Xunzi (fl. 289–238 BCE). The Mozi is a diverse compilation of polemical essays, short dialogues, anecdotes about Mozi, and compact philosophical discussions, the different parts of the book ranging in date from the 5th to the 3rd century BCE. For a detailed discussion of the organization, nature, and authorship of the Mozi, see the following supplement:
