in New Logic/Math Puzzles Posted August 31, 2008 · Report reply How about we have a contest to see who can write the best letter, to convince non-believers, that world peace is worth striving for. I am noticing also, that some of us think it will never happen. Just because something has not happened, does not mean it never will. Does not mean it can't. Good point. The only way to do this is to believe in it. Then we can really start to achive something!
