Ethical romantic love

 

We evolved as social animals. The chimpanzees and gorillas and especially the bonobos are also social animals, and the "love" they show is like the love in a pack of wolves, a boon to survival of the pack and hence its members, excluding outsiders. I don't think much of western "love." It is largely a Hollywood fantasy evolved from Western European romances. When we see a child, especially our own, we fall in love with that baby largely because of a flood of a certain chemical (oxytocin) that floods our brain. It is all there to perpetuate the survival of our genes through that baby and be sure we care for it in spite of the problems and disruption to our lives it causes. If you have ever tried oxytocin you realize how much the emotion of love is chemistry. For a short time one experiences delightful emotions of belonging and love for everyone around. There is another emotion, compassion, that has a more interesting and puzzling source. We can learn compassion, and I think it is one of the foundations of morality. Still, it, too, and the altruism that accompanies it are closely associated with brain chemistry we evolved to help the species get on. One other problem with "love" is that it seems to be so selective. We grieve when those close to us die, note the death of a celebrity with a certain regret, and don't even think about others in that regard.

What you’ve described captures the distinction between evolutionary biology’s perspective on attachment and the cultural mythology of love. From a biological standpoint, love is often a set of behaviors and hormonal responses—oxytocin, vasopressin, dopamine—that evolved to secure reproductive success and social cohesion. Your observation about parents’ love for a child is a textbook example: oxytocin spikes in both the parent and the infant during bonding, making the care and protection of that child feel intensely rewarding, independent of conscious choice. In wolves, chimps, and bonobos, social bonds and “affection” function similarly—they maintain group stability, cooperation, and ultimately survival.

Western notions of romantic love, by contrast, overlay these chemical and social instincts with a rich layer of storytelling and social expectation. Courtly love, Renaissance poetry, Hollywood films—they all exaggerate and idealize what is at its core a mix of chemistry and social bonding strategy. This explains why it often feels intense and selective: the brain isn’t wired to love impartially; it evolved to prioritize kin, mates, and the social network that supports one’s survival.

Compassion, as you note, is more cognitively flexible. It can extend beyond kin or immediate allies, and it can be learned or cultivated—through reflection, meditation, or exposure to others’ suffering. Its neurochemical roots—oxytocin, endorphins, and other modulators—still serve a biological purpose, but they are “unlocked” by awareness and moral reasoning, allowing us to act altruistically toward strangers. In that sense, compassion becomes a foundation of morality precisely because it can bridge the selective bonds of instinct.

And yes, the selectivity of love is striking. The grief we feel for close friends or family compared with strangers or distant tragedies shows that our “emotional moral radar” evolved for survival efficiency, not universal fairness. It’s why compassion is harder to elicit than instinctive attachment, and why ethical systems often strive to expand it beyond the narrow bounds of kin and tribe.

If you like, we could dig into how this chemical and social view of love and compassion intersects with ethics—why morality often demands what our brain chemistry does not naturally supply. It’s a fascinating tension.

Ideally our behavior is based on our ethics, which tends to consist of a set of rules of thumb and associated modifications and exceptions we've thought through mindfully in terms of harm. It has little to do with conscience except we accept feed from conscience as part of the process.

Exactly. What you’re describing aligns with a rationalist or reflective view of morality: ethics as a consciously developed framework for guiding behavior, rather than a reflexive product of instinct or emotion. Conscience, in this sense, is more like a sensor: it gives feedback on how our actions align with our internalized ethical rules, but it doesn’t dictate them. The real engine is mindful reasoning—deliberating on harm, fairness, consequences, and principles.

This explains why people can act ethically even when their instincts—or emotions like selective love—pull in another direction. We may feel a pull to favor kin, friends, or certain groups, but ethics lets us step back, weigh harm, and decide to act fairly or altruistically toward those outside our immediate circle. Conversely, conscience can mislead if it’s poorly calibrated—say, through cultural indoctrination or unexamined bias—but if we treat it as data rather than law, it’s a useful input rather than the foundation.

It’s an interesting inversion of the typical “ethics comes from conscience” idea: here, conscience is a tool for ethics, not the source of it. In practice, that means the morally mature person isn’t simply obeying gut feelings—they’re testing and refining them against a reasoned understanding of harm, rights, and social consequences.

If you want, I can map this view to how evolutionary instincts like love and compassion interplay with rational ethics—why our biology gives us raw materials that ethics must refine.

You add fairness and consequences to my criterion of harm. Consequences can be good or bad and bad consequences is the same as harm, so the point is to increase good. As for fairness, that is a hard one.

You’re right—if we take harm as the central measure, then negative consequences are already covered. Positive consequences—well-being, flourishing—aren’t strictly required to define what’s ethical if your criterion is simply minimizing harm. Ethics could, in principle, be purely defensive: avoid harming others, regardless of whether you actively create benefit. That’s a defensible minimalist position.

Fairness is trickier because it isn’t directly about harm in the moment—it’s about the distribution of harms and benefits. A situation can minimize immediate harm but be unfair in the sense that some bear burdens while others reap advantages. Fairness seems to matter because humans are wired to detect inequity: perceived unfairness generates social tension, resentment, or reciprocal harm later. From that perspective, fairness may be a secondary, instrumental principle: promoting fairness reduces harm in a wider, longer-term sense, even if it doesn’t change immediate outcomes.

So fairness is hard because it straddles the line between ethics as a measure of harm and ethics as a measure of social stability or relational quality. You could see it as a meta-harm criterion: we care about fairness not for its own sake, but because unfairness is likely to cause harm eventually. It’s why societies codify fairness into rules, even when short-term harm might be minimal.

If you like, I can sketch how this “harm-first, fairness-instrumental” approach compares to common Western ethical frameworks—it’s surprisingly compatible with some modern moral philosophy.

No, a good ethical system does indeed want to maximize good.

Ah, I see—so you’re moving from a purely harm-minimization baseline to a fuller consequentialist framework: ethics is about minimizing harm and promoting positive good. That makes sense, and it aligns with what some philosophers call “positive consequentialism” or “well-being maximization.” In this view, an action isn’t merely ethical if it avoids harm—it is better the more it actively contributes to the flourishing, welfare, or genuine benefit of others.

Fairness still fits in, but now it can be seen as a tool for maximizing good rather than just minimizing harm. A fair system tends to generate trust, cooperation, and stability, all of which increase net well-being. So fairness isn’t an independent rule to follow blindly—it’s valuable because it reliably produces positive outcomes across a group.

This also helps explain why ethical reasoning can extend beyond instinctive attachments. Biology gives us selective love and compassion, but conscious ethics lets us step back and ask: “What action will produce the greatest net good, beyond my immediate circle?” It’s a rational, reflective harnessing of impulses toward a broader, more universal goal.

If you want, we can explore how such a system handles conflicts—for instance, when maximizing good for one group could harm another, or when short-term gains clash with long-term well-being. That’s where ethics gets really interesting.
