How Regulation, Not Willpower, Shapes Our Capacity for Love, Forgiveness, and Ethical Behavior
There is a quiet revolution happening in the world of marriage and family therapy, and it begins not in our thoughts or values but in the vagus nerve.
Where we once asked, “Why did he do that?” we now ask, “What state was his nervous system in?”
This is not to absolve wrongdoing. This is not some soft-focus relativism.
This is a shift—one that moves moral reasoning away from the cold marble bust of Kant and toward the pulsing tissues of mammalian co-regulation.
Because before we can make an ethical decision, we must feel safe enough to consider one.
In the words of poet Jericho Brown:
“Compassion is something we practice in our breathing.”
It turns out the breath, quite literally, makes us human.
We Don’t Behave Ourselves—We Co-Regulate Into Goodness
For most of modern psychology, morality was framed as the triumph of the cortex over the animal: a matter of values, cognition, maybe impulse control. I also previously subscribed to this worldview.
But recent work in polyvagal theory—developed by Stephen Porges and popularized in therapy spaces by Deb Dana—suggests we may need to look lower, deeper, and older.
The ventral vagal system, part of our parasympathetic wiring, governs our ability to connect, attune, and empathize.
When this system is online, we are capable of curiosity, forgiveness, and even nuance. When it’s offline, we return to ancient patterns: fight, flee, freeze, fawn.
Put simply: no safe nervous system, no moral imagination.
In this light, the person who lashes out in anger or collapses into dissociation is not resisting morality. They are beyond the reach of it—at least temporarily—because their body believes it is under siege.
And until that belief is addressed, no amount of scolding, shaming, or moralizing will help.
Regulation Before Redemption
Recent studies bear this out.
Folks with higher heart rate variability (a proxy for vagal tone and flexible nervous system response) are more likely to demonstrate empathy, prosocial behavior, and even equitable decision-making under pressure (Park & Thayer, 2014; Beauchaine et al., 2020).
In one 2025 study on moral dilemmas, participants with stronger vagal regulation were less rigid, less punitive, and more sensitive to context (Gomez et al., 2025). They were less likely to apply one-size-fits-all ethical rules and more likely to consider the human story behind the choice.
This is not a spiritual theory. This is physiology.
The Apology Begins With the Body
In couples therapy, we see this play out daily.
One partner is furious. The other is collapsed. Both demand resolution. But until their nervous systems are regulated—until they’ve come down from the high tower of reactivity—apologies cannot land. Words don’t stick in a spinning mind.
Deb Dana calls this “befriending the nervous system.” It is not poetic. It is mechanical.
Sit close. Breathe slower. Feel your feet.
Don’t launch into the problem until both of you are in what Porges would call a ventral state—anchored, safe, socially engaged.
Forgiveness, forebeatance, and acceptance are not higher callings. They are a lowering of threat.
What We Once Called Sin, We Might Now Call Dysregulation
This is perhaps the most radical implication of the polyvagal turn:
it reframes failure, betrayal, and even violence as—first and foremost—a nervous system in collapse.
Psychiatrist Gabor Maté suggests that chronic emotional stress and unresolved trauma create systems that overfire and under-trust. In his view, addiction, rage, people-pleasing, and even narcissism can be seen as maladaptive survival mechanisms, not moral weakness (Maté, 2022).
This does not negate responsibility. But it reframes the path to repair.
It says: “You are accountable. But first, you must become safe enough to see what you’ve done.”
The Ethical Case for Breathing Slowly
Ethics used to begin with commandments. Now they may begin with the breath.
Breathwork, coherent rhythm, co-regulation rituals—these are not therapeutic extras. They are the infrastructure of moral repair.
A 2023 study on heart-rate variability biofeedback found that clinicians and healthcare workers who trained their breath patterns not only felt calmer—they showed increased compassion toward patients who previously irritated them (Serrano-Gonzalez et al., 2023).
When the body settles, the soul becomes more generous.
Critics at the Door
As always, not everyone’s on board. Critics of polyvagal theory point out that many of its claims still outpace its peer-reviewed evidence.
Other models—like classic sympathetic-parasympathetic balance or interoceptive brain mapping—offer overlapping explanations without invoking evolutionary ventral hierarchies (Grossman & Taylor, 2007).
Still, even skeptical scientists concede the practical utility of vagal-friendly interventions—coherent breathing, tone of voice, gentle movement—as part of trauma-informed care. You don’t have to believe in every anatomical claim to feel the nervous system’s role in shaping behavior.
A Nervous-System-Informed Ethics
What does it mean to live in a society that understands this?
It means we might stop expecting people to behave well while under siege.
It means we design classrooms, courtrooms, and conversations that de-escalate before they educate.
It means we reframe emotional maturity not as stoicism, but as vagal flexibility.
The ability to return, again and again, to safety—even when the world pulls us toward rage.
In this framework, the emotionally regulated person is not weak or passive. They are dangerous in the best way—capable of holding complexity without collapsing into reaction.
The Slow Work of Becoming Good
Let’s not pretend this is easy.
Becoming someone who can love, forgive, and pause before speaking takes practice.
Not sermons. Not slogans. Practice.
The practice of breathing while listening. The practice of pausing before responding. The practice of noticing your own internal sirens before lighting fires in others.
Wendell Berry wrote:
“It may be that when we no longer know what to do, we have come to our real work.”
This, then, may be our real work: to train our nervous systems not just for survival, but for relationship.
For compassion. For the long, unsexy labor of becoming more human with each breath.
Be Well, Stay Kind, and Godspeed.
