Jeffrey Bub (2018) investigates what we can learn about quantum mechanics from the structure of the correlations it predicts and apart from its detailed mathematical machinery. The present discussion is in the spirit of Bub's project. I examine two arguments, one from Clifton, Pagonis and Pitowsky (1992), and the other from Maudlin (2014). If either is correct, the non-signaling correlations by themselves entail that the quantum world is causally nonlocal. This paper calls both arguments into question. However, it also points out that even if the criticisms succeed, this doesn't settle whether quantum mechanics is causally nonlocal. The answer to that question depends on considerations that go beyond the correlations alone. Arthur Fine's “random devices in harmony” Fine (1981) will play a role as a tool for thinking about correlations that violate Bell-type inequalities.

Jeffrey Bub（2018）研究了我们可以从其预测的相关结构以及详细的数学机制中了解到的量子力学知识。当前的讨论是本着Bub项目的精神。我考察了两个论点，一个来自克利夫顿，帕格尼斯和皮托斯基（1992），另一个来自莫德林（2014）。如果任何一个正确，则非信号相关性本身就意味着量子世界是因果的非局部的。本文对这两个论点都提出了质疑。但是，它也指出，即使批评成功了，这也无法解决量子力学是否因果非局部的问题。该问题的答案取决于超出相关性的考虑因素。亚瑟·芬恩
