Jul 12, 2018 at 17:35 comment added Robert Frost @Wojowu I think the story goes that some universal all-inclusive set would have the size of the greatest cardinal, and Russell's intuition told him this led to a contradiction. Russell's paradox was what he came up with although Cantor had already also worked out Cantor's paradox independently. I can't tell you the precise link. Either way, this then this led to the new constructions of set theory which restricted how sets can be constructed rather than permitting any definable collection to be a set.
