In the present historical context, migratory flows have acquired a particular political and social relevance by showing a deep imbalance in the globalized world. Those who migrate to wealthy countries due to wars or extreme poverty do not have an identity that can be homogenized; they are aliens, strangers carrying destabilizing life experiences. The meeting between the new idea-content represented by the Stranger and the receiving group-container can therefore have catastrophic consequences. The author’s reflection aims to focus on the significance of the figure of the Stranger and on the condition that might support an integration process, starting from an analogy between the collective dynamics of the social environment and the individual psychical ones as experienced in the psychoanalytic setting.
