Dependency always carries with it an adverse valuation and tends to be regarded as a characteristic only of the early years and one which ought soon to be grown out of… whenever attachment behaviour is manifested during later years, it has not only been regarded as regrettable but has even been dubbed regressive. I believe that to be an appalling misjudgement.
Bowlby delivers the corpus’s foundational argument: the term ‘dependence’ has been catastrophically misread by clinical culture, and treating attachment behaviour in adulthood as regressive constitutes a fundamental theoretical error.
