AoPSWiki Article of the Day
Zorn's Lemma was the AoPSWiki Article of the Day for December 19th, 2007

This proof is almost exactly the proof in the appendix of the Lang book I cited at the end of the article—I worked through that proof, digested it, and then typed it up here. Since this would seem to be a standard proof of the lemma (for instance, Wikipedia has an article on the Bouraki-Witt Theorem), I assume this is acceptable. If, however, I have erred, somebody should probably delete the entire proof of the lemma. —Boy Soprano II 13:46, 25 November 2007 (EST)

Okay, this argument also appears in

  • Stoll, R., Set Theory and Logic, Dover, ISBN 0486638294,

so I assume that this argument is public-domain enough for the wiki. —Boy Soprano II 23:39, 25 November 2007 (EST)
