Well, the use of "forever" might be an overstatement on my part. But no one has disproven so far mathematical theorems demostrasted more than 20 centuries ago by Thales, Pythagoras, Archemedes or Euclid. Twenty centuries is obviously not eternity, but it is quite impressive. No other field of human knowledge has resisted so well to the passage of time. About everything that was held to be true 2000 years ago in the fields of physics, medecine, astronomy, natural sciences, etc., is known to be false or at least grossly incomplete and inaccurate; just about everything that was held to be true in the field of mathematics is still held to be true. A rather impressive accomplishment, don't you think? Call it a dogma if you wish, but I do really not see anything religious about it.

Math may be incomplete, and the current mathematical corpus will certainly be superceded by an higher order theory, but I believe that things that are know to be true will remain true.
