Aside from the many political, cultural and economic aspects of the present refugee crisis in Europe, it is also crucial to consider the psychological element. In our fast-changing world, globalisation, advances in communication technology, fast travel, terrorism and now the refugee crisis make psychoanalytic investigation of the Other a major necessity. Psychoanalyst Vamik Volkan, who left Cyprus for the US as a young man, brings his own experiences as an immigrant to bear on this study of the psychology of immigrants and refugees, and of those who cross paths with them. In Part I, case examples illustrate the impact of traumatic experiences, group identity issues, and how traumas embedded in the experience of immigrants and refugees can be passed down from one generation to the next. Part II focuses on the host countries, considering the evolution of prejudice and how fear of newcomers can affect everything from international politics to the way we behave as individuals. Volkan also considers the psychology of borders, from the Berlin Wall to Donald Trump. He argues that it is not enough to sympathise with the material plight of people who have left their homes; we must also strive to understand the mental health issues caused by their uprooting.
