The idea of a universal set seems intuitively desirable in the zermelo fraenkel set theory particularly because most versions of this theory do allow the use of quantifiers over all sets see universal quantifier one way of allowing an object that behaves similarly to a universal set without creating paradoxes is to describe v and similar large collections as proper classes rather than.
