 Gongsun Long (c. 320–250 B.C.E.) was a retainer to the Lord of Pingyuan (d. 252 B.C.E.) in the northern state of Zhao. Anecdotes about him are found in the Zhuangzi and The Annals of Lü Buwei, in which he is depicted advising King Hui of Zhao (r. 298–266 B.C.E.) against war (18.1, 18.7) and in disputation with Kong Chuan, a descendent of Confucius, at the home of the Lord of Pingyuan (18.5). He is mentioned in “Under Heaven” as a leading disputer and in the Han dynasty Records of the Grand Historian (Book 74) as undertaking disputation about the hard and white and the same and different. Intriguingly, the Annals depicts him citing the Mohist principle of “all-inclusive care” (jian ai) to King Hui. Together with his anti-war stance, this suggests that he was influenced by and may once have numbered among the Mohists. The Xunzi does not criticize him by name but does cite a version of his white horse sophism in a list of incorrect uses of names (22.3).
