The property P(n) =

has not been decided. Is the statement P(10^(10^10)) determinate given
that the set of integers exists as a completed whole?

(I am reminded, perhaps for no good reason, of a claim, that I never
quite understood, to the effect that "there exists a prime greater
than 10" is meaningless, or at least improper. I suppose the defect is
that the quantification is over the set of integers.)
Can't we understand the meaning of the statement P(10^(10^10)) without
claiming that it is determinate?
