08/28/25 Grif.Net – Logic Class

In 1998 I taught a college logic class and asked the student=
s a question. If Philadelphia is 100 miles from New York and Chicago is 100=
0 miles from Philadelphia and Los Angles is 2000 miles from Chicago, how ol=
d am I.

 

Brandon in the back of the class raised his hand and when called o=
n said, "Dr. Bob,  you’re 50."

 

I was stunned. "You’re a=
bsolutely correct, but tell me how you logically arrived at the answer so q=
uickly?"

 

He said, "You see Dr. Bob, I have a brother who’s 25 and=
he’s only half nuts."
