A French hors d'oeuvres   
" Je pense, donc je suis "

("I think,  therefore  I exist")


The brain tries to digest the logic in this:

First start out by assuming  that
     there's  an "I" that is thinking
     then just because that
     there's  an "I" that is thinking
     it follows that
    "I"   exist ?

It sure  is tiring
 chasing my own tail .
 Who cares whether
 I  exist  or  not ?
...
I think,  therefore  I am ?
Oh!  but it's thinking that's got me in a jam !
