Cantor wrote Hilbert with an attempted proof of CH in which he used the
absolute infinite in the argument. I believe (but don't remember clearly)
that he wrote to Dedekind in the same vein. That's how hidden Cantor's
views were.
What really upset Hilbert in particular was Russell's demonstration that at
the bottom of Cantor's paradox was an antinomy that on the face had nothing
to do with the infinite. (Arnon, is of course quite right that it was the
comprehension principle that caused the trouble).
