zhong3 lei4 (Class)
Classes differ from Sets in two important respects.
First, Classes are not assumed to be extensional. That is, distinct
Classes might well have exactly the same instances. Second, Classes typically
have an associated `condition' that determines the instances of the Class. So,
for example, the condition `human' determines the Class of Humans. Note that
some Classes might satisfy their own condition (e.g., the Class of Abstract
things is Abstract) and hence be instances of themselves.
