Talmudic Logic

A young man knocks on the door of a great Talmudic scholar.

"Rabbi, I wish to study Talmud."

“Do you know Aramaic?”

“No."

“Hebrew?”

“No."

“Have you ever studied Torah?”

“No, Rabbi, but I graduated from Harvard summa cum laude in philosophy, and received a PhD from Yale. I'd like to round out my education with a bit of Talmud.”

“I doubt that you are ready for Talmud. It is the broadest and deepest of books. If you wish, however, I will examine you in logic, and if you pass the test I will teach you Talmud.”

"Good. I'm well versed in logic."

"First question. Two burglars come down a chimney. One emerges with a clean face, the other with a dirty face. Which one washes his face?”

”The burglar with the dirty face."

“Wrong. The one with the clean face. Examine the logic. The burglar with a dirty face looks at the one with a clean face and thinks his face is clean. The one with a clean face looks at the burglar with a dirty face and thinks his face is dirty. So the one with the clean face washes.”

“Very clever. Another question please.”

“Two burglars come down a chimney. One emerges with a clean face, the other with a dirty face. Which one washes his face?”

“We established that. The burglar with the clean face washes.”

“Wrong. Both wash. Examine the logic. The one with a dirty face thinks his face is clean. The one with a clean face thinks his face is dirty. So the burglar with a clean face washes. When the one with a dirty face sees him washing, however, he realizes his face must be dirty too. Thus both wash.”

“I didn’t think of that. Please ask me another.”

“Two burglars come down a chimney. One emerges with a clean face, the other with a dirty face. Which one washes his face?”

“Well, we know both wash.”

“Wrong. Neither washes. Examine the logic. The one with the dirty face thinks his face is clean. The one with the clean face thinks his face is dirty. But when clean-face sees that dirty-face doesn’t bother to wash, he also doesn’t bother. So neither washes. As you can see, you are not ready for Talmud.”

"Rabbi, please, give me one more test.”

“Two burglars come down a chimney. One emerges with a clean face, the other with a dirty face. Which one washes his face?”

“Neither!”

“Wrong. And perhaps now you will see why Harvard and Yale cannot prepare you for Talmud. Tell me, how is it possible that two men come down the same chimney, and one emerges with a clean face, while the other has a dirty face?"

"But you've just given me four contradictory answers to the same question! That's impossible!"

"No, my son, that's Talmud."

“Between 1305 and the early 1800’s. the House of Taxis ran a form of pony express service all over Europe….   Its couriers clad in blue and silver uniforms, crisscrossed the continent carrying messages between princes and generals, merchants and money lenders.” –Alvin Toffler, The Third Wave We may think we are the first generation consumed by rapid communication but we are not.   Throughout our history it has been a priority. Of course, now in the 21 st century we must ask: are we better or worse for it?
