We have been looking for a psychoanalytical explanation of the striking feature in morbid jealousy, i.e. that patients attach a disproportionate importance to impersonal objects as evidence of the unfaithfulness of the partner. The psychoanalytical literature teaches us on the one hand that fixations to part-objects may be considered as an important mechanism in the genesis of morbid jealousy, and on the other hand that impersonal objects, obtaining an unrealistic meaning, stand in for part-objects in phenomena such as fetishism and persistent transitional objects. The linking of these two findings permits us to assume that impersonal objects in morbid jealousy can stand in for part-objects. This assumption is illustrated by a psychoanalytical approach to the contents of two literary works, Shakespeare's Othello and Wilde's Lady Windermere's Fan, in which an impersonal object plays a central role in jealousy processes.
