多世界中的睡美人问题

The Sleeping Beauty Problem in Many-Worlds

近年来,量子力学的多世界解释越来越受到瞩目。睡美人问题进入哲学家的视野之后也受到了诸多学者的关注。彼得·刘易斯把两者结合在一起,从而得出睡美人问题的答案。而帕匹纽等学者对此提出了针锋相对的批评,彼得·刘易斯对此批评作了回应。问题是从量子力学的多世界解释出发如何得到睡美人问题的答案。如果从大卫·刘易斯的路径去强化彼得·刘易斯的论证,那么这两者不仅具有更强的可类比性,而且能显示出该问题具有更深刻的内涵。

Recently, more and more attention has been paid to the Many-Worlds Interpretation of Quantum Mechanics. Also the sleeping beauty problem has been drawing more attention of scholars after being brought into the discussion of philosophers. Peter Lewis puts the two questions together, and gets one answer for the sleeping beauty problem. However a criticism comes from David Papineau, and Peter Lewis gives his response to it. So the question is how to get the answer from the ground of the Many-Worlds Interpretation of Quantum Mechanics. If argument comes from David Lewis＇ s methodology for reinforcing the view of Peter Lewis, then something deep will come up, as well as a stronger version of the comparison of the two.
