Explanation:
Erik Erikson was a psychologist who developed a theory of social development according to which we go through different stages during our whole lifespan, these stages are basically crisis which we are supposed to solve in order to continue our development.
The last stage of this theory is called ego integrity versus despair and it begins at approximately age 65 and it continues until death. During this stage, people look back and contemplate their lives and the accomplishments they achieved in their lives. If they think they had a meaningful life they achieve a sense of integrity. On the other hand if they think their life wasn't meaningful, they develop a sense of despair.
In this example, Abner has 70 years old and he feels that his life has not been of any real value or significance. <u>Because of his age we can see that he must be in the stage of "ego integrity vs despair" and since he doesn't feel like he lived a meaningful live we can see that he is not achieving a sense of </u><u>integrity</u><u>. </u>
