Abstract

I explore the relationship between a prominent analysis of intrinsic properties, due to Langton and Lewis, and the phenomenon of quantum entanglement. As I argue, the analysis faces a puzzle. The full analysis classifies certain properties of entangled particles as intrinsic. But when combined with an extremely plausible assumption about duplication, the main part of the analysis classifies those properties as non-intrinsic instead. I conclude that much of Lewis’s metaphysics is in trouble: Lewis based many of his metaphysical views—his thesis of Humean supervenience, for instance, and his account of recombination—on an analysis of intrinsicality which does not sit well with quantum phenomena.

内在性和纠缠

摘要

我探讨了因兰顿和刘易斯而对内在特性进行的突出分析与量子纠缠现象之间的关系。正如我所说，分析面临一个难题。完整分析将纠缠粒子的某些特性归类为固有特性。但是，当结合关于重复的极其合理的假设时，分析的主要部分将这些属性归类为非固有属性。我的结论是，刘易斯的许多形而上学都遇到了麻烦：刘易斯的许多形而上学观点——例如，他关于休谟附带性的论文，以及他对重组的解释——都建立在对内在性的分析之上，而这种分析并不适合量子现象。
