John Bowlby

Love is a need, not a weakness

The founder of attachment theory, who showed that the bond between child and caregiver is a basic human necessity.

A secure base is what lets us venture out into the world.
— John Bowlby

Who they were

John Bowlby challenged a generation of thinking by arguing that a child's need for closeness to a caregiver is not indulgence but a survival instinct as real as hunger. Drawing on psychoanalysis, evolutionary biology, and studies of separated children, he described how early bonds form an "internal working model" that quietly shapes our relationships for life. His ideas of the secure base and separation anxiety gave clinicians and parents a new language for emotional security. The trilogy he devoted to attachment, separation, and loss remains a foundation of how we understand human connection.
