客观概率与心身关系
Objective Probability and the Mind-Body Relation
摘要:
量子力学中的客观概率通常被认为涉及一个随机过程,即从一系列可能性中选择一个实际的未来。埃弗雷特的开创性思想是,在指针基础上,所有可能的确定未来都是宏观线性叠加的组成部分。我证明,这两个概念是什么参与量子过程是联系在一起的两个替代解释的身心关系。这导致了对埃弗雷特理论的裂变而不是分歧,并导致了对为什么无差异原则不适用于测量后、观察前主体的自我位置不确定性的新颖解释,正如塞本斯和卡罗尔所声称的那样。他们的认识分离性原则被证明是从这种解释中产生的,从而为埃弗雷特理论的玻恩规则的推导奠定了坚实的基础。
英文摘要:
Objective probability in quantum mechanics is often thought to involve a stochastic process whereby an actual future is selected from a range of possibilities. Everett's seminal idea is that all possible definite futures on the pointer basis exist as components of a macroscopic linear superposition. I demonstrate that these two conceptions of what is involved in quantum processes are linked by two alternative interpretation of the mind-body relation. This leads to a fission, rather than divergence, interpretation of Everettian theory and to a novel explanation of why a principle of indifference does not apply to self-location uncertainty for a post-measurement, pre-observation subject, just as Sebens and Carroll claim. Their Epistemic Separability Principle is shown to arise out of this explanation and the derivation of the Born rule for Everettian theory is thereby put on a firmer footing.
