Commonsense morality holds that monogamy is morally permissible. In this paper I will challenge this, arguing that monogamy is in fact morally impermissible. First I’ll argue that monogamy’s restriction on having additional partners seems analogous to a morally troubling restriction on having additional friends. Faced with this apparent analogy, the defender of monogamy must find a morally relevant difference between the two kinds of restriction. Yet, as I’ll argue, there seems to be no such morally relevant difference, for the standard (...) defenses of monogamy all fail. I take this to be evidence that monogamy’s restriction on having additional partners is in fact morally analogous to a restriction on having additional friends. Just as a restriction on having additional friends is immoral, so, too, is monogamy’s restriction on having additional partners. (shrink)

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. In many cases, monogamy can be justified on grounds of practicality, (...) specialness, or jealousy. (shrink)

Recent work by philosophers such as Harry Chalmers and Hallie Liberto has called into question the moral permissibility of monogamy. In this article, I defend monogamy on a number of grounds, including practical reasons and reasons relating to commitment, specialness, and jealousy. I also attempt to reframe the debate about monogamy as not just relating to the permissibility of restricting one’s partner but as equally about one’s freedom to leave a relationship. Finally, I make a case against Liberto’s claim that (...) monogamous agreements are over-extensive. (shrink)

According to a traditional conception, romantic love is both constant - if someone loves another, they continue to love them - and exclusive - if someone loves another, they love only the other. In this paper, we argue that the essentiality of constancy and exclusivity is incompatible with the possibilities of fission - roughly speaking, of one person becoming two - and fusion - roughly speaking, of two people becoming one. Moreover, if fission or fusion are possible, then constancy and (...) exclusivity are obligatory features of love only if there are moral dilemmas. We conclude by suggesting this casts doubt on the constancy and especially the exclusivity of love. (shrink)

Jealousy has been disparaged as psychologically debilitating and morally flawed since well before Shakespeare wrote Othello and is indeed represented—particularly well—as far back as in Homer's portrayal of gods and goddesses in The Iliad. According to some of these traditional views, often shared by philosophers, psychologists and the general public, jealousy is the sign, if not of an irredeemably corrupt mind, then at least of an excessively possessive and insecure character. But does jealousy always indicate some sort of flaw or (...) failure? Is jealousy rerehensible in all contexts? In the present paper, I intend to suggest some modifications to the view that it is, by giving jealousy a more sympathetic and charitable hearing than it normally receives, and suggesting that jealousy might, in some cases, be justifiable.

McTaggart takes love seriously. He rejects rival accounts that look to reduce love to pleasure, moral approbation or a fitting response to someone’s qualities. In addition, he thinks that love reveals something about the structure of the universe, and that in absolute reality, we could all love each other. In this paper, I follow McTaggart in his rejection of rival accounts of love, but distance myself from his own account of love in absolute reality. I argue that in claiming that (...) we could all love each other, he fails to adequately account for an important part of the phenomena of love, namely chemistry. (shrink)

Sexual infidelity is widespread, but it is also widely condemned, yet relatively little philosophical work has been done on what makes it wrong and how wrong it is. In this paper, I argue that sexual infidelity is wrong if it involves breaking a commitment to be sexually exclusive, which has special significance in the relationship. However, it is not necessarily worse than other kinds of infidelity, and the context in which it takes place ought to be considered. I finish the (...) paper by looking at how the hegemonic norm of monogamy makes infidelity both more likely and more difficult to deal with. (shrink)
