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.
