Separation , the second volume of Attachment and Loss , continues John Bowlby's influential work on the importance of the parental relationship to mental health. Here he considers separation and the anxiety that accompanies it- the fear of imminent or anticipated separation, the fear induced by parental threats of separation, and the inversion of the parent-child relationship. Dr Bowlby re-examines the situations that cause us to feel fear and compares them with evidence from animals. He concludes that fear is initially aroused by certain elemental situations - sudden movement, darkness or separation - which, although intrinsically harmless, are indicative of an increased risk of danger. Attachment and Loss is a deeply important series of works that continue to influence the landscape of psychoanalysis and psychology, and its second volume, Separation , provides a unique exploration of anxiety in the parent-child relationship.
