ABSTRACT
The classical set theory is built on the fundamental concept of “set.” An individual is either a member or not a member of a specified set in question. A sharp, crisp, and unambiguous distinction exists between a member and a nonmember for any well-defined “set” in this classical theory of mathematics, and there is a very precise and clear boundary indicating whether or not an individual belongs to the set. When one is asked the question “Is this individual a member of that set?” The answer is either “yes” or “no.”
