According to High-Dimensional Wavefunction Fundamentalism (HDWF) the wavefunction field evolving in configuration space is all that exists fundamentally. The main argument in favor of HDWF is an argument from separability and locality: separability is a desirable feature of a fundamental metaphysics and HDWF is indeed such a separable metaphysics. Separability in turn is desirable because it is simple and intuitive. Tim Maudlin has recently argued that intuitiveness and simplicity cannot motivate separability. In particular, our intuitions stem from our interactions with the three-dimensional world which is non-separable. Therefore, he concludes, there is nothing else HDWF theorists can appeal to motivate separability. I call this Maudlin’s challenge. The present paper addresses Maudlin’s challenge by showing how the facts that some plurality of entities are separable entail that its constituents are fundamental, for well-motivated notions of fundamentality.

根据高维波函数原教旨主义 （HDWF），在构型空间中演化的波函数场就是根本存在的全部。支持 HDWF 的主要论点是从可分离性和局部性的论点：可分离性是基本形而上学的一个可取特征，而 HDWF 确实是这样一个可分离的形而上学。反过来，可分离性是可取的，因为它简单直观。蒂姆·莫德林 （Tim Maudlin） 最近认为，直观性和简单性不能激发可分离性。特别是，我们的直觉源于我们与不可分割的三维世界的互动。因此，他得出结论，HDWF 理论家没有其他方法可以诉诸于激发可分离性。我称之为 Maudlin 的挑战。本文通过展示一些多个实体是可分离的事实如何意味着其组成部分是基本的，对于动机良好的基本性概念，解决了 Maudlin 的挑战。
