 The text gives no further, substantive explanation of this stance. The Mohists simply declare that the robbers case is “this but not so,” rather than “this and so,” and thus despite the obvious formal similarity between “riding black horses is riding horses” and “killing robber-people is killing people,” drawing parallels (móu 侔) between them is misleading. Previously, of course, the text explained that expressions of different kinds rest on different grounds (gù 故, reasons). On the Mohists’ behalf, then, we can conjecture that the grounds (gù) that justify applying the predicate ‘killing robbers’ diverge from those for ‘killing people’, such that when ‘killing robbers’ is “so,” ‘killing people’ is “not so.” Killing people is murder, the unjustified killing of innocents; killing robbers is the morally justified, legally sanctioned execution of guilty criminals. Similar considerations would apply to the predicates ‘caring about people’ and ‘caring about robbers’. For example, to the Mohists, caring about people entails concern for all people’s benefit; perhaps they hold that since robbers harm others, caring about them is incompatible with concern for all people’s benefit.
