If ‘F’ is a predicate, then ‘Fer than’ or ‘more F than’ is a corresponding comparative relational predicate. Concerning such comparative relations, John Broome's Collapsing Principle states that, for any x and y, if it is false that y is Fer than x and not false that x is Fer than y, then it is true that x is Fer than y. Luke Elson has recently put forward two counter-examples to this principle, allegedly showing that it yields contradictions if there are borderline cases. In this article, I argue that the Collapsing Principle does not rule out borderline cases, but I also argue that the principle is implausible.

崩溃原则是否排除了边缘情况？

如果 'F' 是谓词，那么 'F比'或'更多Fthan' 是一个相应的比较关系谓词。关于这种比较关系，约翰布鲁姆的崩溃原理指出，对于任何X和是的, 如果它是假的是的是F小于X而不是假的X是F小于是的, 那么确实X是F小于是的. 卢克·埃尔森（Luke Elson）最近对这一原则提出了两个反例，据称表明如果存在临界案例，它就会产生矛盾。在本文中，我认为坍缩原则并不排除边缘情况，但我也认为该原则是不可信的。
