 Shells. Holding five shells in his closed fist, a bookie asks the gambler, “How many shells do I have in my hand?” The gambler hasn’t seen the contents of the bookie’s hand, but, for some reason, he has a hunch that there are five shells in the bookie’s hand. On that basis, he judges that there are five shells in the bookie’s hand. So, he replies, “Five.” Does that mean that he knows this claim? Surely not: the gambler has hit the truth merely accidentally (KKh 208).
