kennethreitz ce93f429a2 Add Knowledge: the vault's reference shelf, crosslinked across the site
Publish the Obsidian vault's Knowledge folder as /knowledge (881 notes,
67 folders), with a Knowledge item in the nav and footer.

- scripts/import_knowledge.py regenerates data/knowledge from the vault:
  slugged paths, folder notes as index pages, wikilinks resolved to site
  links (or plain text), callouts, highlights, and Dataview tables
  rendered statically. Personal notes are withheld via an exclusion
  list plus a privacy guard.
- tuftecms/core/knowledge.py builds a concept index from note titles and
  aliases. First mentions on ordinary pages link to their Knowledge note
  (capped, never in headings, code, links, or sidenotes); Knowledge pages
  list related notes and where they're mentioned across the site; other
  pages get a Related Knowledge block.
- Knowledge URLs join sitemap.xml (so the sweep test covers them), never
  displace existing legacy slugs, list alphabetically, and mermaid
  diagrams render client-side only on pages that have them.

## Overview
John Bowlby (1907–1990) was a British psychoanalyst who committed the field's great heresy: he insisted that what actually happens to children matters more than what they fantasize about. Trained in the Kleinian tradition, where the infant's inner world of drives and phantasies was the whole story, Bowlby kept noticing the outer one — the mothers who left, the hospitals that separated, the institutions that fed bodies and starved bonds. His 1944 study of forty-four juvenile thieves found a striking pattern of early maternal separation among the most affectless of them, and the direction of his life's work was set: the child's tie to the caregiver is not a side effect of feeding. It is a primary biological system in its own right.

## Maternal Deprivation
After the war, the World Health Organization commissioned Bowlby to report on the fate of Europe's homeless and institutionalized children. *Maternal Care and Mental Health* (1951) delivered a conclusion that reshaped policy: an infant needs a warm, intimate, continuous relationship with a mother figure, and prolonged deprivation of it does measurable, lasting harm. With his colleague James Robertson, whose film *A Two-Year-Old Goes to Hospital* forced the point on a resistant medical establishment, Bowlby documented the sequence a separated child moves through — protest, then despair, then a detachment that looks deceptively like recovery. Hospitals eventually changed their visiting rules because of this work. The detachment phase, he argued, was not adjustment but defense — the first sketch of what later became the [avoidant](/knowledge/psychology/attachment-theory/avoidant-attachment) strategy.

## The Ethological Turn
Psychoanalysis could not explain his data, so Bowlby went looking for a framework that could. He found it in ethology — Lorenz's goslings imprinting on the first moving figure, Harlow's monkeys clinging to the cloth mother that gave no milk, Robert Hinde's rigorous studies of primate mother-infant separation. Attachment, Bowlby concluded, is an evolved behavioral system: proximity to a protective adult kept infants alive on the savannah, so infants come wired to seek it, and distress at separation is the alarm built into the wiring. The result was the trilogy that took him twenty years — *Attachment* (1969), *Separation* (1973), and *Loss* (1980) — psychoanalysis rebuilt on evolutionary ground.
At the theory's cognitive heart he placed [Internal Working Models](/knowledge/psychology/attachment-theory/internal-working-models): the child abstracts, from thousands of interactions, a working model of the self (am I the kind of person who gets responded to?) and of others (do they come when called?), and carries those models forward as the template for every later bond. It fell to his collaborator [Mary Ainsworth](/knowledge/psychology/attachment-theory/mary-ainsworth) to show that the patterns could actually be observed and classified — the empirical half of the partnership that built [Attachment Theory](/knowledge/psychology/attachment-theory).
