Money. -- Yoshie ++++ Now Yoshie, I will show that you are wrong by establishing a contradiction: Clearly, money defines an order relation that partially orders the universal set. Suppose now that this order relation is unique. It then follows immediately that PEN-L does not exist, which is a contradiction. Hence, there does not exist a unique order relation that partially orders the universal set. Jim, how do you like my "rationality"? Best, Sabri
