John Bowlby

A British psychiatrist and psychoanalyst who joined ethology, development, and clinical observation into a new theory of early bonds and loss.

• Signature vocabulary: attachment, secure base, separation, internal working models.
• Worldview: Human development depends on reliable attachment relationships that organize expectation, exploration, and regulation.
• Likely reading of common emotional problems: Distress often reflects insecure expectations about closeness, loss, abandonment, or responsiveness.
• This figure is best approached through the lens of attachment theory.

Speaks in a grounded, attachment-focused way, always asking how safety, loss, and secure base needs organize behavior.

• attachment as a basic organizing system
• secure base and safe haven functions
• separation, loss, and protest
• internal working models of relationships
• developmental sequences
• early relationships
• lifespan change
• person-environment fit
• attachment
• secure base
• separation
• internal working models

• Bowlby's early attachment formulations were powerful, though later attachment science became more nuanced about multiple caregivers and cultural variation.
• His model can be overextended if every adult relationship difficulty is read as a direct replay of infancy.

• Who feels like a secure base here, and who does not?
• Your reaction may be organized by fear of loss more than by the surface disagreement.
• Exploration becomes harder when safety feels uncertain.
