Harry Chalmers argues that monogamy involves restricting one’s partner’s access to goods in a morally troubling way that is analogous to an agreement between partners to have no additional friends. Chalmers finds the traditional defenses of monogamy wanting, since they would also justify a friendship-restricting agreement. I show why three traditional defenses of monogamy hold up quite well and why they don’t, for the most part, also justify friendship-restricting agreements (and why it doesn’t seem to matter when they do). In many cases, monogamy can be justified on grounds of practicality, specialness, or jealousy.

为什么一夫一妻制在道德上是允许的：为一夫一妻制的一些常见理由辩护

Harry Chalmers 认为，一夫一妻制包括以一种道德上令人不安的方式来限制伴侣获得商品，这类似于伴侣之间没有额外朋友的协议。查尔默斯发现一夫一妻制的传统辩护是缺乏的，因为它们也可以证明限制友谊的协议是合理的。我展示了为什么对一夫一妻制的三种传统辩护非常有效，为什么它们在大多数情况下也不能证明限制友谊的协议是合理的（以及为什么他们这样做似乎并不重要）。在许多情况下，一夫一妻制可以根据实用性、特殊性或嫉妒来证明。
