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. F

FTP, what is this important paradox of early set theory developed by the British co-author of Prinicipia Mathematica?
