Withdrawal occupies a markedly plural semantic field within the depth-psychology and addiction corpus. At least three distinct conceptual registers converge under this heading, and the scholarly reader must hold them simultaneously. First, and most clinically prominent, is pharmacological withdrawal: the syndromic constellation of physiological and affective dysregulation precipitated by discontinuing a substance of dependence. Here Brower, Koob, Naqvi, and Addenbrooke map insomnia as the sole symptom shared across all DSM substance-withdrawal disorders, while Koob traces the neurocircuitry of emotional dysregulation through the withdrawal/negative-affect stage. Alexander complicates the received mythology, insisting that withdrawal symptoms are neither necessary nor sufficient to sustain opioid addiction. Second, Schore invokes conservation-withdrawal as a psychobiological response to shame — a parasympathetically driven retraction from relational engagement, marked by helplessness, elevated cortisol, and object-withdrawal. Third, the I Ching commentators — Wang Bi, Liu Yiming, and the Taoist reading of Cleary — treat Withdrawal as a cosmological and ethical hexagram, a disciplined strategic retreat whereby yang energy is preserved against encroaching yin. This third register intersects unexpectedly with the depth-psychological valorisation of voluntary retreat as transformation. The tensions between these registers — withdrawal as pathological compulsion, as shame-driven collapse, and as cultivated wisdom — give the term its peculiar depth-psychological gravity.
