His concluding passage in Part One describes the psychological reaction of the inmates to their liberation, which he separates into three stages. The first is depersonalization—a period of readjustment, in which a prisoner gradually returns to the world. Initially, the liberated prisoners are so numb that they are unable to understand what freedom means, or to emotionally respond to it. Part of them believes that it is an illusion or a dream that will be taken away from them. In their first foray outside their former prison, the prisoners realized that they could not comprehend pleasure. Flowers and the reality of the freedom they had dreamed about for years were all surreal, unable to be grasped in their depersonalization.
