 Hippias makes three category mistakes, one in each of his answers to the question, “What is the Fine?” (287e–293c) He identifies three kinds of entity that can be fine—a particular (a fine girl), a mass substance (gold), and a universal (living the traditional good life). Socrates’ double strategy is the same in each case: (1) To show that the answer fails the generality requirement; it does not explain all the cases of being fine. (2) To show that the fine entity to which Hippias refers is not fine in every context. This violates the exclusion requirement, for it does not exclude non-fine things. It also implies that the answer fails to satisfy the explanation requirement; generally, to explain Xness, something must be X no matter what (synonymy requirement). If fire explains heat, that is because it is always hot; but gold cannot explain fineness, because gold is not always fine; it is foul as material for cookware. All of these answers fail for two kinds of reasons: because they are merely examples of fine things, and because they identify things that are fine only in certain contexts, leaving unanswered the question of what makes them fine in those contexts but not in others.
