 The explanation of sameness in being “of a kind” bears on the questions raised at the end of section 4 about the grounds for recognizing some kinds and not others and the explanation of why particular things count as members of one kind or another. The Mohists’ explanation of being “of a kind”—“having a respect in which they’re the same”—might at first glance seem to allow that any group of things with anything in common could be considered a kind. Could the collection of items in your desk drawer then constitute a kind by virtue of their similarity in being in the drawer? A view that allows an affirmative answer might make identification of kinds highly arbitrary, leading to an extreme relativist or conventionalist view on which almost any group of things could count as a kind. However, the Mohists would probably reject such an extreme view. A collection of things in a drawer might be “the same” in being united, or grouped together, the third of the four types of sameness above, but presumably it would not be “the same” in being “of a kind.” Rather, the Mohists seem to hold that to be of the same kind, things must possess one or more shared, intrinsically similar features, such as their visible characteristics (mào 貌) or shape (xíng 形) (Robins 2012). Nevertheless, since there are indefinitely many respects in which things might have similar observable features, the Mohist stance could still be quite liberal, allowing things to be divided up into various kind distinctions depending on which features a speech community happens to attend to.
