Dana Scott just told this joke, which he heard from Ray Smullyan:

Two professors at a math conference stand in front of a blackboard, on which is written the sentence "Only an idiot would believe a sentence like this!" The first professor asks the second, "Do you believe that?" The second answers, "Of course not! Only an idiot would believe a sentence like this!"

A syllogism has three parts. Therefore, this is not a syllogism. <><><><>Posted by<><> <><>< HREF="" REL="nofollow" TITLE="michaelsinger at hotmail dot com">Michael Singer<>
