 This implicitly realist view of similarity relations and kind distinctions seems operative as well in canon B2, which indicates that we can be mistaken in how we project kind relations, since features of individual exemplars may not generalise to all members of their kind. The canon again seems to assume that the kind relation between an exemplar and others of its kind exists independently of our identifying it, and so questions can arise as to whether we are extending kinds properly. If kind relations were not independent in this way, the features by which we distinguish and name the exemplar could simply define what features are “so” of the kind.
