Love is a big part of our lives. We see it in songs, stories, and poems. But when did it become something we could study with science?

This article looks at how love slowly became a topic for researchers. You’ll learn who studied love first, how it changed over time, and why science still studies love today.

📜Old Ideas About Love

Love Before Science

Long ago, love was not studied in labs. It was part of myths, philosophy, and stories from different cultures.

🏛️In Old Times (Ancient Greece)

In ancient Greece, big thinkers like Plato and Aristotle talked about the nature of love.

• Eros – Romantic or passionate love

• Philia – Friendship or brotherly love

• Agape – Pure and selfless love

💡 This wasn't science yet. But these ideas helped later scientists and psychologists think more deeply about emotions.

🧪 The First Scientist to Study Love

🧬 Charles Darwin and Love as Evolution

The first to study love through science was Charles Darwin. In 1872, he wrote:

🧠 "Love is often expressed by a peculiar shining appearance of the eyes."

In his book The Expression of the Emotions in Man and Animals, Darwin said love had evolutionary roots. It helped humans and animals stay connected and survive.

🧠 Psychology Joins In – Early 1900s

Science started to look at the mind and love in the early 1900s thanks to psychologists.

🧑‍🏫 Sigmund Freud's Ideas on Love

Freud said:

• Love and desire affect how we act.
• We first love our parents.
• That shapes how we love later in life.

He believed love was tied to deep needs we don't always know we have.

🧑‍🦱 Carl Jung’s View

Jung added to Freud’s work. He said love shows up in shared human stories, or myths, across the world.

🧲 New Science of Action – Mid 1900s

Harry Harlow changed how we think about love. He did tests with baby monkeys:

• One "mom" gave food but was made of wire.
• One "mom" was soft but gave no food.
• The monkeys clung to the soft one.

💛 Love is more than food. It is about touch, safety, and care.

❤️ John Bowlby and Attachment

John Bowlby said the first bond with our parents shapes how we love later in life.

This formed the base of Attachment Theory, still used today in therapy.

🧠 Love and the Brain – Modern Times

🔬 Dr. Helen Fisher and Brain Scans

In the 1990s, scientists used fMRI brain scans to watch what happens in the brain during love.

Dr. Helen Fisher found:

• Love lights up the reward system in the brain.
• These are the same parts that light up with sugar or drugs.
• Chemicals like dopamine, oxytocin, and vasopressin are very active.

🧪 Three Stages of Love (Science View)

Modern science breaks love into 3 stages:

• Lust – Run by sex hormones like estrogen and testosterone.
• Attraction – Linked to dopamine and serotonin.
• Attachment – Powered by oxytocin, the “cuddle chemical.”
