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)

Monogamy in Western countries has recently undergone criticisms, because it is perceived as an oppressive institution, adjacent to reactionary cultural values. In this article, I argue that monogamy is in fact a force of social progress and women’s empowerment. I point out that, given our natural tendencies, the most likely alternative to monogamy is polygyny. By its very nature, polygyny faces a numerical difficulty, to the extent that (given the equitable male to female ratio) when one man (...) engages in romantic or sexual relationships with multiple female partners, inequality and social conflict ensues. I present historical and sociological data that sustains the argument that polygyny is associated with greater inequality, violence, poverty and women’s vulnerability. Nevertheless, while monogamy can be considered a force of social progress, I argue that the State is not morally entitled to prosecute non-monogamous lifestyles, but there may still be non-coercive ways to promote monogamy.

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)

Monogamy, I’ve argued, faces a pressing problem: the difficulty of finding a morally relevant difference between its restriction on having additional partners and a restriction on having additional friends. To the extent that we’d find a restriction on having additional friends morally troubling, that puts pressure on us to judge the same about monogamy. This argument, however, has recently come under attack by Kyle York, who defends monogamy on grounds of specialness, practicality, and jealousy. In this paper (...) I’ll argue that, pace York, these defenses of monogamy all fail. (shrink)

Applications of sexual selection theory to humans lead us to expect that because of mammalian sex differences in obligate parental investment there will be gender differences in fitness variances, and males will benefit more than females from multiple mates. Recent theoretical work in behavioral ecology suggests reality is more complex. In this paper, focused on humans, predictions are derived from conventional parental investment theory regarding expected outcomes associated with serial monogamy and are tested with new data from a postreproductive (...) cohort of men and women in a primarily horticultural population in western Tanzania (Pimbwe). Several predictions derived from the view that serial monogamy is a reproductive strategy from which males benefit are not supported. Furthermore, Pimbwe women are the primary beneficiaries of multiple marriages. The implications for applications of sexual selection theory to humans are discussed, in particular the fact that in some populations women lead sexual and reproductive lives that are very different from those derived from a simple Bateman-Trivers model.

The word monogamy derives from the Greek words μóνoδ meaning one and γάμoδ meaning marriage. When Christianity was founded, polygamy (the marriage of a man to many women) was, at that point in Judaic history, regarded as acceptable practice. The Gospel according to Matthew reports that Christ restored marriage to its original unity and indissolubility (Matt. 19:6). Monogamy is still deeply entrenched in the Christian tradition. It has long been held that polygamy and polyandry undermine the dignity due (...) to man and woman as parties to the marriage contract. The command “What God has joined together let no man put asunder” (Mark 10:9) is still a central part of the marriage ceremony of many denominations notwithstanding widespread changes of attitude and practice. -/- .

Studies of collegiate sexuality have not examined infidelity. Using in-depth peer interviews with college students, our article investigates the meanings and practices of “monogamy” and “cheating” for college women. College women use ideas about age, class, and gender to construct collegiate sexuality as a kind of “monogamy lite” exempt from the “rules” of adult sexuality. Many have cheated themselves. Simultaneously, they define “real” relationships as exclusive and condemn “cheaters” as bad people. We employ an intersectional analysis to analyze (...) these discrepancies, arguing that the multiple meanings women use reconcile contradictions between expectations for women’s sexuality and expectations about collegiate behavior, allowing women to sustain a commitment to relationships while also participating in collegiate sexual culture. Moreover, by providing a socially legible, gender-appropriate way to end unwanted relationships, these meanings allow women to use cheating to solve dilemmas in their intimate lives. In this case, college women use middle-class ideas about the transition to adulthood to resist gendered imperatives. (shrink)

The norm of monogamy is pervasive, having remained widespread, in most Western cultures at least, in spite of increasing tolerance toward more diverse relationship types. It is also puzzling. People willingly, and often with gusto, adhere to it, yet it is also, prima facie at least, highly restrictive. Being in a monogamous relationship means agreeing to give up certain sorts of valuable interactions and relationships with other people and to severely restrict one’s opportunities for sex and love. It is (...) this restrictiveness which has led for calls among some philosophers for the justification of the norm, and some have argued that it cannot be justified. John McMurtry, for example, writing in 1972, compared monogamy to private property and argued that it serves the capitalist order (McMurtry 1972, 596–97). More recently, Harry Chalmers (2019) has argued that monogamy is morally impermissible. In this chapter we argue that rather than justify the norm, we ought to explain and understand its pervasiveness. Not everyone who follows the norm is doing so blindly, irrationally, or immorally. Indeed, many people are monogamous because being monogamous supports their needs and best enables them to flourish. We suggest that the human need for trust and attachment could underlie many people’s desires for monogamy and, therefore, explain monogamy’s pervasiveness. Focusing on the human need for trust and attachment security can also help us to understand why sexual infidelity can feel like such a betrayal. It can make sense to mutually agree to exclusivity in relationships, in spite of the apparent restrictions this brings. In a sense, not all restrictions are restrictive, because holding ourselves to limits on our behavior can in fact help us to invest in and experience the things we value most. (shrink)

After a brief discussion of the terms "monogamy" and "nonmonogamy," I evaluate explanations offered by different theorists for the pain that nonmonogamy can cause to the partner (especially a female partner) of a nonmonogamous person (of either sex). My suggestion is that the self, especially the female self, is conventionally defined in terms of sexual partners. I present and reply to a possible objection to this explanation, and then discuss my theory's normative implications.

Almost all of us have entered or will one day enter a specifically standardized form of monogamous marriage. This cultural requirement is so very basic to our existence that we accept it for most part as a kind of intractable given: dictated by the laws of God, Nature, Government and Good Sense all at once. Though it is perhaps unusual for a social practice to be so promiscuously underwritten, we generally find comfort rather than curiosity in this fact and seldom (...) wonder how something could be divinely inspired, biologically determined, coerced and reasoned out all at the same time. We simply take for granted. (shrink)

This groundbreaking look at the array of styles and modes of relationships proposes a new paradigm for understanding intimate relationships, challenging the monogamy/polyamory binary and offering fresh possibilities for thinking about contemporary love, sex, gender, and sexuality.

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)

The article looks again at the English debate over Anglo-Scottish union in the period 1603 to 1607. It reconstructs what marriage meant to contemporaries, as sociocultural practice as well as political model. It argues that Englishmen's attention to their local circumstances -- sui generis since the Henrician reformation -- sank the union project. The debate also promoted a distrust of blood-right kingship that was crucial to its abolition a generation later. The body of the paper is designed as a case (...) study of how to situate 'ideas in context'. It is intended to challenge, by example, key assumptions that inform the dominant model for that project, articulated pre- eminently in Quentin Skinner's work. The conclusion addresses the theoretical dimension explicitly, critiquing Skinner's rationalist model with specific reference to his recent work on conceptions of liberty in seventeenth-century England.

This second part of a two-part series exploring implications of the natural differences between the sexes for the cultural evolution of marriage considers how the institution of marriage might evolve, if Kant’s reasons for defending monogamy are extended and applied to a future culture. After summarizing the philosophical framework for making cross-cultural ethical assessments that was introduced in Part I and then explaining Kant’s portrayal of marriage as an antidote to the objectifying tendencies of sex, I summarize Kant’s reasons (...) for rejecting polygamy and for viewing monogamy as the only ethically acceptable form of marriage. Finally, I argue that if we apply Kantian principles to the real situation of marriage in many modern cultures, and if we wish to maintain a legitimate place for marriage in the future evolution of human culture, then the future evolution of marriage laws must recognize polyfidelity (i.e., plural marriages for both men and women) as being just as legitimate as monogamy.

The different distribution of "sexual strength" throughout the female and male life-span, and the resulting social backlogs of unsatisfaction in older women and young men, are cited as natural conditions having as final upshots the inferior social status ascribed to women and the permanent tendency toward war. To break the constellation of sexual adaptations which aggravates the tendencies toward war, the author suggests the introduction of "more generosity" into sex, i.e., the discarding of absolutist sex ideology.--E.

How would you feel about your husband, wife, or partner masturbating using pornography or erotica? For many, this would be a betrayal – a kind of cheating. I explore whether monogamous relationships should forbid solo masturbation using erotica and pornography, considering two possible objections: (1) the objection that such activity is a kind of infidelity; (2) the objection that such activity involves attitudes, usually attitudes towards women that are incompatible with an equal, loving relationship. I argue that the use of (...) erotic material in solo masturbation should not count as cheating. Solo use of pornography differs significantly from interpersonal sexual activity. Thus, unlike causal interpersonal sex, it does not undermine the role of sex within the relationship. Additionally, freedom to explore sexual fantasy through masturbation is an important element of sexual autonomy. Objection (2) holds against some but not all erotic material. Sexual enjoyment of pornography that depicts, or is produced by, suffering or degradation involves a way of seeing others that has implications for the user’s relationships with others, particularly sexual relationships. However, not all erotic material involves objectionable attitudes towards others. Thus partners should allow moderate use of some types of erotica in solo-masturbation. (shrink)

Controversially, psychologist and public intellectual Jordan Peterson advises “enforced monogamy” for societies with high percentages of “incels.” As Peterson’s proposal resonates in manosphere circles, this chapter reconstructs and briefly evaluates the argument for it. Premised on the moral importance of civilizational sustainability, advocates argue that both polygamous and socially monogamous but sexually liberal mating patterns result in unsustainable proportions of unattached young men. Given the premises, monogamous societies are probably justified in maintaining their anti-polygamist social and legal norms. The (...) case for imposing stricter sexual norms on socially monogamous but sexually liberal societies is weaker, however, as male involuntary celibacy in those places isn’t as directly caused by male intrasexual competition, and since less intrusive social interventions are more likely to ameliorate “the incel problem.”.

As various forms of nonmonogamy have grown in social visibility, the subject has received academic treatment across a range of literatures, including philosophy. To aid in philosophical treatment, the paper addresses the narrow but fundamental topic of the meaning of nonmonogamy. By engaging with recent literature, it examines nonmonogamy as the rejection of or opposition to monogamy. After exploring the nature of opposition in this case, the paper develops the beginnings of a more detailed theory of nonmonogamy. How do (...) monogamy and nonmonogamy relate? If nonmonogamy is a rejection, what content does the concept of nonmonogamy have? The paper does not criticize monogamy or defend nonmonogamy, but it aims to take part in building the conceptual foundations for nonmonogamy as a political project. (shrink)

It appears that spouses have less reason to hold each other to a norm of monogamy than to reject the norm. The norm of monogamy involves a restriction of spouses' aeeess to two things of value: sex and erotic love. This restriction initially appears unwarranted but can be justified. There is reason for spouses to aeeept the norm of monogamy if their marriage satisfies three conditions. Otherwise, there is reason to permit non-monogamy. Some spouses have reason (...) to accept the norm of monogamy because this will avoid reasonable hurt and prevent diversion of resourees needed to sustain the marriage. Other spouses have reason to permit non-monogamy to allow the spouses access to aspects of a well-rounded life. The choice to be either monogamous or non-monogamous ean also be non-instrumentally valuable if chosen for the right reasons. (shrink)

In any theory satisfying the no-signaling principle correlations generated among spatially separated parties in a Bell-type experiment are subject to certain constraints known as monogamy relations. Recently, in the context of the black hole information loss problem it was suggested that these monogamy relations might be violated. This in turn implies that correlations arising in such a scenario must violate the no-signaling principle and hence can be used to send classical information between parties. Here, we study the amount (...) of information that can be sent using such correlations. To this aim, we first provide a framework associating them with classical channels whose capacities are then used to quantify the usefulness of these correlations in sending information. Finally, we determine the minimal amount of information that can be sent using signaling correlations violating the monogamy relation associated to the chained Bell inequalities. (shrink)

Voles are attracting attention because genetic variation at a single locus appears to have a profound impact on a complex social behavior, namely monogamy. After briefly reviewing the state of the most relevant scientific literature, I examine the way that this research gets taken up by the popular media, by scientists, and by the notable philosopher of neuroscience Patricia Churchland and interpreted as having deeply revisionary implications for how we ordinarily understand ourselves as persons. We have all these big (...) questions we would like to resolve about free will, consciousness, our understanding of persons, and the nature of morality and there is a tendency to ask more of neuroscience than it can yet answer. I do not deny that advances in neuroscience may eventually bear on important philosophical issues. However, it is not at all clear that this research has many of the sweeping implications being claimed for it and, in communicating science responsibly to the public, there is reason to be cautious about suggesting that it does.

The target article, which is part of a larger study, the International Sexuality Description Project (ISDP), seeks to explore cross-culturally aspects of human mating behavior on a global scale. However the nonrepresentation of large cultures restricts the depth of this study. The inferences drawn from such a sample must therefore remain limited despite the impressive sample sizes. In a larger context it raises thoughts on how partial disclosures may misrepresent the design of the larger study.

The downsides of monogamy are felt by most people engaged in long-term relationships, including restrictions on self-discovery, limits on friendship, sexual boredom, and a circumscribed understanding of intimacy. Yet, a "happily ever after" monogamy is assumed to be the ideal form of romantic love in many modern societies: a relationship that is morally ideal and will bring the most happiness to its two partners. -/- In Why It’s OK to Not Be Monogamous, Justin L. Clardy deeply questions these (...) assumptions. He rejects the claim that non-monogamy among honest, informed and consenting adults is morally impermissible. He shows instead how polyamorous relationships can actually be exemplars of moral virtue. The book discusses how social and political forces sustain and reward monogamous relationships. The book defines non-monogamy as a privative concept; a negation of monogamy. Looking at its prevalence in the United States, the book explains how common criticisms of non-monogamy come up short. Clardy argues, as some researchers have recently shown―monogamy relies on continually demonizing non-monogamy to sustain its moral status. Finally, the book concludes with a focus on equality, asking what justice for polyamorous individuals might look like. (shrink)
