Well, that's exactly the opposite :)
There is nothing but certainties in math, since everything is proved in a non-discutable way.
{1} has infinitely many (ℵo) successors.
If {1, 2, 3, ..., n} has infinitely many (ℵo) successors, then {1, 2, 3, ..., n, n+1} has infinitely many (ℵo) successors, for every accessible natural number.
