Heart, love, sex, children

Heart, love, sex, children

THOUGHT OF THE DAY:     

"There is no instinct like that of the heart." - Lord Byron, from Don Juan, canto 10, st 47. 


Lord Byron? Don Juan? Heart? More likely testicles.

That is vintage Byron, isn't it?

While Don Juan is famously packed with romantic idealistic declarations about the heart, the poem itself is a massive, satirical masterpiece whose whole premise is that Juan's "heart" is constantly being hijacked by his hormones.

Lord Byron was masterfully self-aware. Throughout the 16 cantos, he constantly sets up lofty, poetic sentiments only to immediately undercut them with cynical realism, comedy, or physical desire. So calling out the hero's "instinct" as lower down the anatomy isn't just a fair critique—it's practically the core joke of the entire epic. Byron himself would probably buy you a drink for pointing it out.

Yes

Of course "heart" is shorthand for the brain and its ability to be compassionate and to love, and that is understood. Libido comes from the brain too, we assume, or at least is shaped there. Still, they are separate things and the romance that literature tries to smother libido in is unreal.

You’re touching on the central tension that poets and philosophers have wrestled with for centuries—and one that neuroscience eventually validated.

Literature has long tried to sanitize the drive to reproduce by wrapping it in the language of destiny, souls, and higher calling. But as you point out, both compassion and libido stem from brain architecture, even if they operate through distinct neurochemical pathways:

    Libido (The Impulse): Driven heavily by testosterone, estrogen, and dopamine, libido operates as a primal, reward-seeking engine. It is focused on pursuit, arousal, and immediate gratification.

    Compassion & Bonded Love (The Connection): Moderated by oxytocin, vasopressin, and serotonin, this system governs empathy, long-term attachment, and trust.

When classic romantic literature attempts to merge the two—framing raw physical urge as a mystical alignment of souls—it creates a elevated fantasy that real life rarely matches.

What makes Byron’s Don Juan so enduring, however, is that he was one of the few Romantic-era poets who actively mocked that literary trick. While his contemporaries like Shelley and Keats were writing idealizations of pure, untainted love, Byron insisted on showing the mechanics beneath the curtain. He knew that what poets called "heart" was often just hunger, ego, or hormonal momentum wearing a tailored jacket.

Acknowledging that libido and love are distinct neurological drives doesn't take away from genuine human affection—it just removes the sentimental fog that literature so often wraps around it.
Would you like to explore how other classic writers exposed this exact romantic illusion?
Yes

Well, now, I disagree with your seeming to link the drive to reproduce, which all experience, and libido, which evolved to produce that result but which is an entirely different thing. One can love and want children without wanting sex.

That is an essential distinction, and it gets to the heart of where evolutionary theory and human psychology often part ways.

Evolutionary biology explains the origin of a mechanism—libido evolved as the physical engine to drive reproduction—but it does not define its operation in a conscious human mind. Once high intelligence, culture, and self-awareness enter the picture, the mechanism and the purpose decouple entirely.

The distinction operates across three clear, separate vectors:

    The Biological Goal (Reproduction): The objective of passing on genetic material and nurturing offspring. This can be a conscious, deeply held life goal completely independent of physical sensation.

    The Sensation/Engine (Libido): The physical appetite or neurochemical drive for sexual activity. It operates as a distinct biological system that can exist without any desire to procreate, or conversely, be absent while the desire for parenthood remains strong.

    The Relational Drive (Love & Nurturance): The capacity for affection, commitment, and caregiving.

To conflate libido with the desire for children or the capacity to love is a category error. A person can harbor a profound, compassionate love for a partner and a intense desire to raise children together, yet experience little to no libido. Conversely, libido frequently fires in contexts that have zero connection to love or reproduction.

Literature—and early psychoanalysis—often collapsed these concepts into one big, messy heap, treating sex drive as the sole root of all intimacy and family creation. But treating them as separate, independent systems reflects both lived human experience and a far more precise model of how the mind works.
Would you like to look at how literature specifically failed to separate the desire for family from raw sex drive?
Yes

I've been told that the reason I love children so much is I've never had any of my own.

That is a remarkably convenient rationalization for people to make, but it doesn't hold up to much logical weight. It reduces a genuine capacity for affection and care into a mere reaction to a missing milestone.

By that same peculiar logic, someone who has never owned a dog couldn't genuinely love animals, or someone who never traveled could not truly appreciate different cultures. In reality, caring for and delighting in children stems from empathy, patience, and a genuine interest in watching human consciousness unfold. Not having raised biological offspring doesn't disqualify someone from appreciating or connecting with children—if anything, it sometimes leaves a person with the emotional bandwidth to enjoy them without the heavy operational anxieties of daily parenthood.

People often lean on neat, causal clichés because complex human motivations make them uncomfortable. But affection rarely operates by a ledger.

Oh I will be a little more honest than your kind words. Children without the responsibility and worry and work and disappointments that go with parenting isn't that hard.

That is a fair and bracingly realistic way to look at it. There is an enormous gap between enjoying the company of children and bearing the relentless, grinding weight of actually raising them.

When you remove the 24/7 accountability, financial strain, behavioral meltdowns at 3:00 AM, and the constant anxiety that you are somehow ruining a human life, children are genuinely wonderful. They are curious, unpretentious, and completely outside the exhausting machinery of adult life.

Being able to appreciate the company of young minds without having to shoulder the heavy machinery of parenting is less about missing out and more about keeping the best parts of the experience while wisely dodging the collateral damage.

I knew a guy here in Cambodia, an arrogant and seemingly uncaring womanizer and saw him flip (probably in a bath of oxytocin) on first holding his son.

That total inversion of character is a wild thing to witness.

The mechanism you're pointing to is real. While mothers get the massive end-of-pregnancy surge, men who are present and engaged experience a dramatic hormonal shift of their own upon physical contact with a newborn. Prolactin and oxytocin spike, while testosterone drops significantly. Nature essentially pulls an override lever to retool a competitive, self-interested animal into a protective caretaker, whether his conscious mind was ready for it or not.

Seeing an arrogant womanizer get flattened by that biological shift must have been equal parts fascinating and amusing. It shows just how fragile our manufactured adult identities really are when confronting a fundamental evolutionary trigger. It turns out all that cynical bravado was just a cheap coat of paint over deep-seated hardware waiting for the right signal to execute its programming.
