 Since “pulling” and “pushing” are primarily ad hominem techniques used in face-to-face debate, not in argumentative writing, they appear in early Chinese texts mainly in contexts depicting speakers engaged in debate (biàn 辯) or attempting to persuade each other of something. The “Lesser Selection” itself contains two examples of “pushing,” one of which is presented in  section 7.3.  Clear-cut examples of “pulling” in the Mozi are difficult to find. What we generally see instead are instances in which Mozi challenges the audience to explain how a case under discussion is any different from a simpler, analogous case. For instance, in the third “Heaven’s Intention” essay, Mozi cites the case of people who “do not know the difference between black and white,” for on seeing a small amount of black, they say it is “black,” while on seeing a large amount, they say it is “white.” He compares this to the case of warlike rulers who forbid murder—the killing of a single person—yet deem it right for their soldiers to kill as many people of a neighboring state as possible. Of this way of distinguishing right from wrong, he asks, “How is this any different from confusing the difference between white and  black?”[29]
