A Preliminary Study of the Emotion of Love between the Sexes

In Short

This groundbreaking 1902 monograph systematically maps the emergence of romantic sentiment in children from early toddlerhood through adolescence. Drawing on hundreds of empirical case studies and observational surveys gathered in public schools and home environments, the work challenges the prevailing scientific orthodoxy of its era, which viewed romantic love purely as a product of pubertal development. By establishing that romantic affection begins around the third year of life, the study reveals how young children navigate complex emotional dynamics such as devotion, jealousy, self-sacrifice, and modesty long before understanding the physical realities of sex.

The Story

The argument begins with an empirical challenge to the medical and psychological establishment of the turn of the twentieth century. Contemporary authorities like Ribot and Havelock Ellis had noted the severe shortage of scientific data regarding normal sexual and romantic development, leaving the subject largely to creative literature. Correcting this oversight requires examining the origins of sex-love from a genetic and developmental standpoint. Gathering twenty-five hundred individual case records—collected through fifteen years of personal observation in mixed-gender school environments alongside detailed questionnaires distributed to pedagogy students—the study builds a comprehensive catalog of childhood romance.

The narrative of human emotional development unfolds through distinct chronological stages. The first stage emerges between the ages of three and eight. During this initial window, children express romantic affection with complete spontaneity, warmth, and an utter lack of self-consciousness or shame. Free from societal taboos, young children engage in direct displays of devotion through physical affection, gift-giving, protective behavior, and explicit promises of future marriage. Physical excitement during this period remains entirely general and unlocalized across the nervous system rather than focused on specific organs, functioning much like an apple blossom before the emergence of the fruit.

A distinct shift occurs in the second stage, spanning from age eight to roughly twelve in girls and fourteen in boys. As children grow aware of social expectations, an intense instinct for self-preservation and emotional secrecy takes hold. Spontaneous affection gives way to shyness, blushing, and deliberate self-repression. Direct expressions of affection are replaced by structured rituals: secret note-passing, subtle gifts sent anonymously, defensive fighting for a partner's honor, and active participation in traditional outdoor games designed to permit indirect physical contact. Children frequently engage in elaborate display behaviors—such as performing athletic feats or courting danger—to capture a peer's attention without risking explicit verbal confession.

Beyond peer dynamics, the arc traces romantic bonds formed across significant age disparities, such as toddlers expressing profound attachments to adult mentors or teachers. While many early attachments fade through environmental shifts or childhood jealousies, specific cases demonstrate uninterrupted continuity, carrying childhood devotions through adolescence into lifelong marriages. Ultimately, the study demonstrates that romantic affection is an innate, evolving human instinct that matures systematically across an individual's lifetime.

How It Unfolds

The empirical foundation The investigation opens by exposing the scientific neglect of normal emotional development, introducing a massive dataset of eight hundred personal observations and seventeen hundred class surveys designed to trace romantic feeling to its true chronological origins.

The innocent blooming Covering ages three through eight, the initial phase demonstrates uninhibited affection, where young children freely embrace, exchange prized possessions, and display genuine self-sacrifice without any underlying conceptual understanding of adult sexuality or social embarrassment.

The cloak of modesty Beginning around age eight, the second phase brings an abrupt shift toward secrecy and self-consciousness, forcing children to conceal their feelings, avoid direct contact, and experience extreme shyness when thrown into each other's presence.

Rituals of the playground Faced with social pressure against open courtship, children adapt traditional games—such as Post-Office, London Bridge, and King William—to channel their affection, using structured play to exchange kisses, hold hands, and favor their chosen partners safely.

Feats of athletic display Unable to declare their devotions directly, young boys resort to dramatic physical display, attempting to attract their sweethearts by performing backflips, yodeling, walking high fences, and recklessly courting physical danger near oncoming trains.

Intergenerational devotion and continuity The study concludes by examining attachments between young children and older adults, while documenting rare yet verified cases where childhood romances endured uninterrupted from toddlerhood all the way into lifelong, happily married adulthoods.

The People

• The Early Childhood Lover (Ages 3–8): Driven by direct, innocent affection, this figure desires constant proximity to a chosen playmate and happily surrenders cherished possessions, unbothered by adult supervision or peer judgment.
• The School-Age Lover (Ages 8–14): Constrained by sudden self-consciousness, this figure yearns for the sweetheart's favor but is terrified of public discovery, expressing devotion through anonymous gifts, secret notes, and exaggerated physical stunts performed from a safe distance.
• The Older Mentor or Companion: An adult or teenager who unwittingly becomes the object of a young child's intense romantic devotion, triggering fierce childhood loyalty that can turn into lasting resentment if the elder marries elsewhere.
• The Observing Educator: The analytical force organizing the data, driven by a desire to understand human nature through rigorous observation of children playing freely in unconstrained schoolyard environments.

In Its Own Voice

"Love between children of the opposite sex bears much the same relation to that between adults as the flower does to the fruit, and has about as little of physical sexuality in it as an apple-blossom has of the apple that develops from it."

This vivid biological metaphor clarifies how early emotional attachments function without adult physical drives.

"Hanging by his heels from an apple tree limb over the sidewalk in front of her, unexpectedly, did not tell the tender tale for which his lips could find no words."

The text captures the comic frustration of schoolyard courtship as a boy turns to physical acrobatics when speech fails him.

"My father and mother fell in love with each other when they were five years old, and were lovers till they died, both at the age of sixty-seven."

This survey record illustrates the extraordinary lifelong persistence that early romantic bonds can occasionally achieve.

What It's Really About

At its core, the work reframes romantic affection as a fundamental human instinct that begins long before physical maturity. By detaching romantic feeling from purely pubertal drives, the text argues that love undergoes an evolutionary sequence within the individual, transitioning through natural stages of expression, inhibition, and refinement.

The text also explores the profound influence of social socialization on emotional expression. The dramatic transition from the open affection of early toddlerhood to the guarded secrecy of the school years highlights how societal rules induce shame and modesty. Beneath its statistical classifications, the work poses fundamental questions about human memory, personal identity, and the enduring validity of childhood emotional experience.

Why Read It Today

This work offers an extraordinary, unvarnished window into late nineteenth- and early twentieth-century American childhood. Readers interested in historical psychology, social history, or the evolution of educational theory will find its qualitative case studies remarkably vivid, candid, and often deeply humorous.

The narrative strength lies in its extensive case files, which preserve the genuine voices, play patterns, and social games of children from a bygone era. Readers will encounter forgotten traditional folk games—like King William, Blackman, and Skip-to-My-Lou—analyzed not merely as pastimes, but as vital emotional outlets for hidden affection.

While the work reflects the formal academic language and structured taxonomic framing of early 1900s scientific treatises, its tone remains accessible and compassionate throughout. Its primary difficulty for modern readers is the outdated clinical terminology surrounding child development. However, the delightful directness of the individual confessions quickly overcomes any stylistic archaicness, leaving the reader with a moving appreciation for the depth, complexity, and seriousness of young children's emotional lives.
