The concept of bond traverses the depth-psychology corpus along two distinct but interlocking axes. The first is cosmological and archaic: Onians’s monumental excavation of Greek, Roman, Norse, Celtic, and Vedic thought reveals bond as a primary metaphysical category — fate, death, obligation, and even divine decree are conceived as literal cords binding mortals, gods, and the earth itself. From the Homeric peírata to the Roman nexus, from Vedic sin as a cord to Celtic spells of binding, the bond is not metaphor but ontological fact. The second axis is psychobiological and relational: Bowlby, Panksepp, Schore, Siegel, and Flores map how attachment bonds form, sustain, and rupture across the life-span, with touch activating opioid systems that reinforce the social bond and early caregiving relationships shaping neural architecture. Between these poles — archaic-mythological and clinical-developmental — the corpus registers significant tensions. Bion reads the libidinous bond within group psychology as the signature of the pairing basic assumption, while trauma theorists such as Dayton and the ACA literature document how ‘trauma bonding’ perversely binds child to abusive parent. Hari and Flores converge on dislocation — severed bonds — as the hidden engine of addiction. The term thus anchors both the oldest cosmological imaginings and the most contemporary neuroscience of relationship.
