Therefore CH is false.
Corollary: CH is true. Proof: Since Goedel 1940 we know that it is logically consistent to assume that there exists f, a bijection between the set of countable ordinals (i.e., aleph_1) and P(N). By the principle above, f mathematically exists. Therefore CH is true. QED
(Note: The above "corollary" stems from an earlier sci.math discussion regarding the relationship between CH and Pen Maddy's "MAXIMIZE".)
