What does it mean to be human? Object relations, the British- based development of classic Freudian psychoanalytic theory, is based on the belief that the human being is essentially social; the need for relationship is central to the definition of the self. Object relations theory forms the base of psychoanalysts' work, including Melanie Klein, D. W. Winnicott, W. R. D. Fairbairn, Michael Balint, H.J.S. Guntrip, and John Bowlby. Lavinia Gomez here provides an introduction to the main theories and applications of object relations. Through its detailed focus on internal and interpersonal unconscious processes, object relations can help psychotherapists, counselors and others in social service professions to understand and work with people who may otherwise seem irrational, unpredictable and baffling.
