| Set Theory: set theory is the system of rules and axioms, which regulates the formation of sets. The elements are exclusively numbers. Sets contain individual objects, that is, numbers as elements. Furthermore, sets contain sub-sets, that is, again sets of elements. The set of all sub-sets of a set is called the power set. Each set contains the empty set as a subset, but not as an element. The size of sets is called the cardinality. Sets containing the same elements are identical. See also comprehension, comprehension axiom, selection axiom, infinity axiom, couple set axiom, extensionality principle._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Tt makes no sense to assume that there is a privileged term of a set, so that the entities that the meet different conditions, all are distinguished from the entities that satisfy the privileged theory. >Paradoxes, >Levels (Order)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
