The question he addresses here is, What are the emotional bonds that hold collective entities, such as an army and a church, together? It is a fruitful question, and Freud offers some interesting answers. But Group Psychology and the Analysis of the Ego stands chiefly as an invitation to further psychoanalytic exploration.
Sigmund Freud (1856-1939) is one of the twentieth century's greatest minds and the founder of the psychoanalytic school of psychology. His many works include The Ego and the Id; An Outline of Psycho-Analysis; Inhibitions; Symptoms and Anxiety; New Introductory Lectures on Psycho-Analysis; Civilization and Its Discontent, and others.
