The Psychology and Philosophy of Polyamory

By Dr Neel Burton — Psychiatrist, philosopher, and wine writer; Fellow of Green Templeton College, University of Oxford; author of over twenty books.
In 1882, Friedrich Nietzsche, Lou Salomé, and Paul Rée had themselves photographed in a studio in Lucerne. Salomé stands behind a small cart, brandishing a whip, while the two philosophers are harnessed in front of her. It is the most famous photograph in all philosophy.
The photograph arose out of an extraordinary love triangle. Nietzsche and Rée had both proposed marriage to the 21-year-old Salomé, who rejected them both. Instead, she suggested that the three form a platonic ‘intellectual trinity’ and wander in search of a place in which to establish a commune of free spirits.
It did not end well. Within months, Salomé and Rée had vanished from Nietzsche’s life, leaving him devastated. But perhaps the most interesting thing about their failed experiment is not that it failed. It is that the arrangement Salomé proposed still strikes us as so strange.
We readily accept that a person can love several friends, several siblings, and several children. Why, when it comes to romantic love, must there be only one?
Why Romantic Love Is Exclusive
The answer has much more to do with paternity than with love. A man who wished to pass his name, status, and property to his own children needed some assurance that those children were indeed his. This created a powerful incentive to control female sexuality, and helps to explain two things: why polygamy is almost always polygyny, and why, historically, adultery and promiscuity have been judged much more severely in women than in men.
Romantic love, when it eventually arrived, became entangled in an older system of marriage and monogamy established to regulate sex and reproduction. This chronology raises the intriguing possibility that we have confused a precondition of marriage, exclusivity, with a precondition of love.
Can Love Be Divided?
To love more than one person is not necessarily to love each person less, just as to love two children is not necessarily to love each child less. ‘True love’, wrote PB Shelley (d. 1822), ‘in this differs from gold and clay / That to divide is not to take away.’ Love is not finite like money or time, or gold and clay, but grows in the giving.
If having a second child is not to betray the first, and taking on a new friendship is not to diminish our old friendships, why should romantic love alone obey a different arithmetic?
Love may not be finite, but time and attention are. Having a second child need not diminish our love for the first child, but it inevitably changes the distribution of our time and attention. And, you know what, maybe it does diminish our love for the first child. Maybe taking on a new friendship does diminish our old friendships. After all, firstborns and old friends often feel this way. Maybe things are more complicated than the binary truths we tell ourselves to simplify our lives.
Polyamory as an Experiment in Love
In 2006, the term polyamory (‘many loves’) made it into the Oxford English Dictionary. Polyamory is the philosophy or state of being romantically involved with more than one person at a time, with the knowledge and consent of all parties involved. The focus of polyamory is more on intimacy than on sex, and polyamorous relationships, while being romantic, need not be sexual.
Polyamory is not the same as polygamy, which, unlike polyamory, is culturally sanctioned and codified. And it is not the same as cheating, swinging, or free loving, since the focus is on intimacy and relationship building, with the knowledge and consent of all parties involved. While some people see their polyamory as an identity or orientation, others see it more in terms of an ethical alternative to infidelity.
Despite its ethical dimensions, polyamory is more heavily stigmatised than cheating: cheating may threaten the system, but at least operates from within it, whereas polyamory outright does away with it. Like a lie, which is defined in relation to the truth, cheating accepts the principle of romantic exclusivity even as it violates it.
Polyamory in Practice
Polyamory has long been recognised as an alternative lifestyle in gay subculture, and is becoming more and more mainstream, driven, among others, by feminism, gay emancipation, and the fragmentation of families and communities.
Polyamorous relationships can take many forms. They are often triads, or quads—maybe one couple with another. ‘Polyfidelity’ refers to a closed polyamorous relationship in which the parties agree to restrict themselves to one another, rather than take outside lovers. In some cases there may be a primary couple with one or more ‘secondary’ partners who are perhaps more distant or occasional. In other cases, one partner may have, or wish for, outside relationships, while the other may be content with just the primary relationship.
The partners of one partner, who are not also one’s partners, are referred to in the jargon as ‘metamours’, and it is in the spirit of polyamory that one treats them with courtesy and respect, as potential friends rather than rivals.
For some people, polyamory is experienced less as a lifestyle choice than as an orientation, leading to demands for legal recognition and protection for at least some forms of polyamorous relationships.
The Burden of the One
The modern romantic couple, closed as it is on itself, carries an extraordinary burden. One quite unqualified person may be expected to be lover, best friend, confidant, amanuensis, domestic partner, financial partner, co-parent… for decades and into old age. And when it transpires that this person is unable to meet all our needs, we may come to regard this as a failure of love.
Polyamory acknowledges that some people’s relational needs are best met by more than one person, and, conversely, relieves the pressure of having to meet all of another person’s needs. By creating more space around a tired, claustrophobic relationship, it can breathe new love and new life into the relationship.
Because polyamory is non-exclusive, existing relationships and friendships are less likely to be abandoned or neglected in favour of ‘the one’, leading to a larger and stronger social network with more resources, skills, and perspectives to draw upon.
Unlike with serial monogamy, there is less incentive to write off an older relationship—and, by extension, a part of our history and who we are—simply because a more exciting or practical one has come along.
Indeed, there is something particularly brutal, even unnatural, about how someone with whom we have shared the best years of our life can suddenly become not merely a stranger but persona non grata. Surely, we can be better than this.
Love, Jealousy, and Possession
Of course, polyamory, too, has drawbacks. From a young age, we are taught that true love is the love of just one person, and that that person will be able to meet all our needs. The princess awaits her prince, and, when he finds her, they live happily ever after. There is no question of another prince, and still less of a squire or lady-in-waiting. Given this state of affairs, and the stigma of polyamory, it may be hard to find people, or enough people, with whom to conduct polyamorous relationships. But this is more a criticism of society than of polyamory proper.
People are naturally prone to possessiveness and jealousy, even when they insist they aren’t. The princess does not await some prince, but her prince. A new relationship is full of enthusiasm and excitement, or, to give it its proper name, ‘New Relationship Energy’—which can be tough on an existing partner. Jealousy can be even more of an issue if half of a couple is polyamorous, while the other half merely tolerates, rather than embraces, it. Having someone else’s smell on your partner’s skin and in your bedsheets is more than just a little confusing.
Jealousy is often treated as childish possessiveness. But it is more complicated than that. It may express fear of abandonment, helplessness, inadequacy, threatened status, or the perfectly rational recognition that our partner is committing precious time and attention to another and, all the while, comparing us.
Constraints do not always impoverish us. Sometimes, by closing off possibilities, they enable other possibilities to develop more fully. Romantic exclusivity may constrain love, but it may also preserve and concentrate it.
Triangles Needing to Be Squared
Polyamory demands time, energy, security, self-knowledge, emotional intelligence, and communication skills. Things can get pretty complicated, which can undermine the quality of the relationships and the very viability of the enterprise. Many people may not have the time, energy, or skills to manage much more than one relationship, and, of course, may not feel a need for more than one partner, if even that. For many people, the ideal number of partners is not one or two, but one-third or half.
This brings us back to Nietzsche, Salomé, and Rée. Their difficulty was not simply that three people were involved, but that the three did not want the same thing. Salomé envisaged an intellectual trinity; Nietzsche wanted Salomé; Rée had also proposed to her. While Nietzsche and Rée had been friends, neither had a romantic interest in the other, but merely tolerated the arrangement for the sake of Salomé. Although in a love triangle, their desires were not triangular.
The Measure of Love
Polyamory is neither the solution to love nor the end of monogamy. If anything, thinking seriously about polyamory reveals why monogamy has proved so enduring. Love may not be finite, but we are; jealousy is not simply a social convention to be unlearnt; and constraints, far from merely constraining us, can preserve and concentrate what we value most.
But polyamory also reveals how much unnecessary baggage we have loaded onto monogamy. To love one person need not mean possessing that person, expecting them to meet our every need, neglecting our other relationships, or banishing former lovers from our lives. Nor need we mistake exclusivity, inherited from the institution of marriage, for the essence or measure of love.
There may be a time in our lives for polyamory. But even if we decide to outright reject it, there is much to be gained from adopting a more fluid, flexible, and forbearing approach to relationships—and stealing a bit more life from the closing jaws of death.
