Goo and learne what that meaneth: I have pleasure in mercy and not in offerynge. For I am not come to call the rightewes but the synners to repentaunce.

- Empty set (Wikipedia)
In mathematics, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero. Some axiomatic set theories ensure that the empty set exists by including an axiom of empty set, while in other theories, its existence can be deduced. Many possible properties of sets are vacuously true for the empty set.
