"let w be the predicate: to be a predicate that cannot be predicated of itself. Can w be predicated of itself? From each answer, the opposite follows. Likewise, there is no class (as a totality) of those classes which, each taken as a totality, do not belong to themselves. From this I conclude that under certain circumstances a definable collection does not form a totality." Russell (June 16, 1902, letter to Frege)
