A basic fact about sets is that there are two sets only when their memberships differ. The membership of the set of things that are phlogiston is exactly the same as the membership of the set of things that are Devil-dealing Salem witches. In each case, there are none. So in each case the set of instances is the set with no members, the null set.

按集合观，不承认这里有不同的共相，因为基础事实是，两个集合不同当且仅当成员不同，而这两个集合是相同的，因为都是没有成员的集合，即空集。
