 In a footnote to the same pages, Wiggins gives a list of other examples of terms which permit individuation but not counting: “wave, volume of fluid, worm, garden, crystal, piece of string, word-token, machine”. Wiggins continues by explaining that, on his view, his account does not disagree with Strawson’s but corrects and enlarges it (2001: 75). We find it puzzling that Wiggins dismisses “animal” as a sortal but is willing to include “machine” which seems at least as problematic
