Independently discovered by Ernst Zermelo, this mathematical consequence was first communicated by its author in 1902 to Gottlob Frege.
Independently discovered by Ernst Zermelo, this mathematical consequence was first communicated by its author in 1902 to Gottlob Frege. It defines a set A which contains all objects that are not members of themselves. If A is not an element of A, it meets the requirements to be in A. If A is an element of A, then it cannot be an element of A by the definition of the set. FTP, what is this important paradox of early set theory developed by the British co-author of Prinicipia Mathematica?
