  A natural response here would be to point out that the Mohists’ own view implicitly recognizes that knowledge of words, or “names,” constitutes a separate type of knowledge, distinct from knowledge of how to “select” things. The Mohists ought to categorize knowledge more finely, the response would run, by distinguishing between knowing how to use names and knowing how to distinguish the referents of names. (Full mastery of a concept would presumably require both abilities.) The later Mohist texts do precisely this, presenting a fourfold categorization of knowledge that includes knowledge of names, knowledge of things, knowledge of relations between names and things, and knowledge of how to act (see the separate entry for “Mohist Canons”). Nevertheless, in this earlier text, no value is attached to knowledge of names. What counts as genuine knowledge is the reliable ability to distinguish things in practice.
