我关注三个分体学原理：部分的外延性（EP）、组合的唯一性（UC）和组合的外延性（EC）。这些原则并不等同。然而，它们是密切相关的（并且经常被等同），因为它们都反映了基本的唯名论格言“没有差异制造者就没有差异”。所有这些，无论是单独的还是集体的，都受到了哲学基础上的挑战。在第一部分中，我认为此类挑战并不完全具有威胁性（EP），因为它们要么会弄巧成拙，要么得不到支持。在第二部分中，我认为它们几乎没有破坏（UC）和（EC）的可持续性。
I focus on three mereological principles: the extensionality of parthood (EP), the uniqueness of composition (UC), and the extensionality of composition (EC). These principles are not equivalent. Nevertheless they are closely related (and often equated), since they all reflect the basic nominalistic dictum ‘No difference without a difference maker’. All of them, individually or collectively, have been challenged on philosophical grounds. In the first part I argue that such challenges do not quite threaten (EP), because they are either self-defeating or unsupported. In the second part I argue that they do little to undermine the tenability of (UC) and (EC) either.
