"n Z set theories, there is no set S such that every ordinal is a
member of S.
In ordinary class theories, there is no set S such that every ordinal
is a member of S, but there is a proper class C such that every
ordinal is a member of C"
i am not talking about what set theories or ordinary class theories allow
i am talking about
is there a set of all ordinals
obviously such a set was accepted in Burali-fortis day as they came up
with the paradox
did canto accept such a set
which since set theory has now been denied only by introducing an axiom
