  Weak excluded middle states that for every propostiion P, either ¬¬P or ¬P holds.

  We give a proof of weak excluded middle, relying just on basic facts about real numbers,
  which we carefully state, in order to make the dependence on them transparent.

  Some people might doubt the formalization. To convince yourself that there is no cheating, you should:

  * Carefully read the facts listed in the RealFacts below to see that these are all
    just familiar facts about the real numbers.
