Loss: Sadness and Depression (Attachment and Loss, Volume III) is a work by John Bowlby (1980).

Core claims

Bowlby’s Loss completes the most sustained empirical challenge to psychoanalytic instinct theory by demonstrating that sadness and depression are not regressive libidinal states but evolved responses to disrupted attachment bonds — repositioning mourning as a biological process with its own adaptive logic rather than a failure of ego function.
The book’s distinction between healthy mourning and chronic/disordered mourning functions as a diagnostic heuristic that exposes how parental unavailability — not the death of the object per se — produces the pathological variants Freud grouped under “melancholia,” anticipating by decades the empirical findings of developmental psychopathology.
By insisting that defensive exclusion of attachment information (not repression of instinctual drives) is the mechanism behind prolonged grief and depression, Bowlby provides the information-processing bridge that connects object relations theory to cognitive science, making Loss the hinge text between mid-century psychoanalysis and contemporary affective neuroscience.

How does Bowlby’s concept of defensive exclusion in Loss compare to Hillman’s account of the psyche’s “self-presentation” versus the ego’s “self-preservation” in Archetypal Psychology: A Brief Account — are they describing the same defensive operation from incompatible epistemologies?
Hollis argues in Swamplands of the Soul that “nothing which is internalized is ever lost,” while Bowlby insists that the reorganization of internal working models requires accepting the permanence of absence — do these positions contradict or complement each other on the question of what mourning accomplishes?
Thomas Moore’s invitation in Care of the Soul to “invite Saturn in” and honor depression as initiation sits uneasily beside Bowlby’s clinical evidence that chronic mourning constitutes genuine pathology — where does the boundary fall between soul-deepening and defensive exclusion?
