Within the depth-psychology corpus, ‘legacy’ operates across two principal registers that are held in productive tension. The first and most theoretically elaborated is the intrapsychic-transgenerational register, developed most fully by Richard Schwartz in the Internal Family Systems framework. Here, legacy designates inherited psychological burdens — beliefs, affects, and behavioral dispositions — transmitted across generations without requiring the recipient’s direct experience of the originating trauma. Schwartz distinguishes these sharply from personal burdens and demonstrates their operation in individual psychopathology, family systems, and collective cultural formations such as racism, materialism, and patriarchy. The second register appears in Ogden’s sensorimotor and attachment-informed tradition, where legacy names the implicit relational knowing encoded in procedural memory through early caregiving — an embodied inheritance that constrains relational capacity and therapeutic enactment alike. Ogden’s treatment is notably bidirectional: attachment legacies may be positive resources to be deepened as well as negative imprints to be transformed. Pargament’s coping psychology adds a third inflection, distinguishing between denial of war legacy, pathogenic legacy, and growth-generative legacy. Across all three traditions the term marks the same fundamental insight: psychic life is never wholly self-originated but carries the weight of what has been transmitted, encoded, and not yet metabolized.
