An integrative characteristic of the personality that characterizes the successful resolution of the psychosocial conflict “ego-integration versus despair” and is expressed in a sense of integrity and satisfaction with the life lived at the stage of late maturity. Ego-integration, from the point of view of E. Erikson, is manifested in the rethinking and reflection of the life lived, the experience of the world order and the spiritual meaning of the person’s personality, the acceptance of one’s life path as the only one that is due, the rethinking of relationships with loved ones, including parents, and the feeling of belonging to the principles of past times. Ego-integration as personal maturity is manifested through wisdom, which E. Erikson defines as a detached interest in life in the face of death. The lack of ego-integration is manifested in a hidden fear of death, a feeling of constant failure.
