{Jerry wears improper glasses (to decieve)=A}
Lloyd Braun in order for him (to appear sane)=B \ (to himself)=C
{By wearing the improper glasses he (is decieved)=1\A}
not recognizing George, making him (to appear not sane)=1/B \ (to another)=1\C
if Lloyd Braun actually is sane he is still being decieved because Jerry's trick was to convince Lloyd Braun that he really does wear glasses, and that is a deception, even if Jerry is only decieving him to convince him of the truth. Lloyd's belief in Jerry wearing glasses and his belief in his own sanity are two separate beliefs, even if one is the result of the other.
If anyone has the sienfeld episodes on DVD they should forward outlines of the plots on this forum. This one doesn't present the entire scope of the episode, but it points out the repetition of diametric opposition used in the plot. I think it would be an instructive resource for us students. I don't have the DVD's so I have to wait for the farce like episodes to air.
