The author considers a relational perspective of mourning and suggests an elaboration and extension of Freud's theory of mourning with a sharper focus on the dialectic of holding on and letting go of the formative lost object relationship. Sussillo argues that Freud's early (1917) theoretical tilt toward the relinquishment of affective ties with the dead, later expanded and culminated in a deeper relational sensibility, was shaped by his developing theories and personal losses. Her position is that the analyst can help facilitate the adult patient's affective experience of felt continuity with the absent object, lost in adolescence, that ultimately allows the separation and the transformation of the primitive bond. Sussillo's perspective represents a synthesis of relational theories in a broad sense—also informed by attachment theory, contemporary bereavement research, infant research, and developmental theory. This thesis is illustrated by a clinical example that highlights the therapeutic action.
