How do you really know that you love someone? Is it when you feel happy around them? When you miss them? Or when you feel deep pain after losing them? Love can feel magical, confusing, exciting, and even painful at the same time.
Many people try to understand love using logic and reasoning. But famous philosopher Martha Nussbaum believes that love cannot be understood only through the mind. Sometimes, the heart knows the truth before the brain accepts it.
In her book Love’s Knowledge, Nussbaum explores a powerful idea about how we understand love. She studies writers like Marcel Proust and thinkers from Plato to Zeno, showing that true knowledge of love often comes through emotional experience — especially pain. Let us understand this idea in simple words.
The Problem: Why Is Love So Hard to Understand?
Love is not simple. When we fall in love, we may:
- Confuse love and attraction
- Idealize the other person
- Try to protect ourselves from getting hurt
- Convince ourselves we do not care when we actually do
Nussbaum says we often deceive ourselves about love. We tell stories in our minds to avoid pain. We may say, “I am not in love anymore,” just to protect ourselves.
But then something happens — a shock, a loss, a moment of deep emotion — and suddenly the truth becomes clear.
Martha Nussbaum’s “Incompleteness Theorem of the Heart”
Nussbaum suggests that love cannot be fully understood by logic alone. She describes something like an “incompleteness theorem of the heart.” This means:
The mind cannot fully explain what the heart knows.
We may think clearly and analyze our feelings carefully. But sometimes our thinking hides the truth instead of revealing it.
Proust’s Example: Love Revealed Through Pain
Nussbaum discusses the famous novel In Search of Lost Time by Marcel Proust. In the story, the main character, Marcel, convinces himself that he no longer loves Albertine.
But when Albertine dies, he feels intense sorrow. That deep pain shows him the truth — he truly loved her.
What Does This Teach Us?
- Sometimes suffering reveals love
- Rational thinking can hide real emotions
- Emotional shock can remove self-deception
Marcel’s pain was not just sadness. It was a powerful realization. His heart knew what his mind was denying.
How Intellect Can Mislead Us
Nussbaum explains that we often use intellect like a calculator. We analyze relationships like this:
- What are the benefits?
- What are the costs?
- Can I replace this person with someone else?
But love is not a business deal. It cannot be measured by profit and loss.
When we use only logic, we may miss the depth of our emotions. Nussbaum says this kind of thinking creates emotional myopia — short-sightedness of the heart.
The Role of Habit in Self-Deception
One important idea Nussbaum highlights is habit.
When we get used to someone, we may stop feeling strong emotions. We may think, “Maybe I do not love them anymore.”
But being used to someone does not mean love has disappeared. Habit can make emotions feel calm, but they still exist deep inside.
In Marcel’s case, he thought he did not love Albertine because he was used to her presence. Only loss broke that habit and showed the truth.
Catalepsis: A Moment of Absolute Certainty
Nussbaum uses the Greek idea of catalepsis, which means a strong, unshakable impression of truth.
This happens when:
- The feeling is intense
- The emotion is unexpected
- The experience feels completely real
Pain often creates this kind of certainty. When we suffer deeply after losing someone, that suffering itself proves love.
Important Idea
Love is not just something hidden inside waiting to be discovered.
Love is created and revealed through emotional experience — especially suffering.
Love vs Infatuation
Nussbaum also explains the difference between true love and infatuation.
| Feature | True Love | Infatuation |
|---|---|---|
| Emotional Depth | Deep and lasting | Intense but short |
| Mutuality | Often mutual | Can be one-sided |
| Pain Response | Deep grief after loss | Temporary sadness |
| Self-Knowledge | Leads to growth | Often self-focused |
Marcel’s realization was painful and personal. He understood that his love was not just about Albertine — it was about something deep within himself.
The Danger and Openness of Love
Nussbaum calls love a “dangerous openness.”
When we love someone, we:
- Become vulnerable
- Risk suffering
- Accept emotional uncertainty
Many people try to protect themselves by denying love. But denying love also reduces our emotional life. It is like closing the door to both joy and pain.
According to Nussbaum, love is a permanent feature of the human soul. We move between love and denial, suffering and comfort. That is part of being human.
Final Understanding: How Do You Know You Love Someone?
You know you love someone when:
- Their absence creates real pain
- You cannot simply replace them
- Your emotions surprise you with intensity
- Your heart feels certain, even if your mind doubts
True knowledge of love comes from lived experience — not from logical calculation.
Understanding love is not as simple as solving a math problem. According to Martha Nussbaum, we often hide from our real feelings using logic and habit. But powerful emotional experiences, especially suffering, can reveal the truth.
When we feel deep pain after losing someone, that pain itself becomes proof of love. Love is not just a thought; it is something we live, feel, and sometimes suffer through.
It makes us vulnerable, but it also makes us human. By accepting both the joy and the pain of love, we come closer to understanding its true nature.
FAQs
1. Can you know you love someone without suffering?

2. Why does pain prove love?
Because pain shows deep emotional attachment. If someone’s loss hurts deeply, it means they mattered greatly.
3. Is love only emotional and not logical?
Love involves both emotion and thought. But emotion plays a stronger role in revealing its truth.
