Carl Jung, Alfred Adler, and others... Carl Jung started off being a student in Freud's classes. Soon, he became a close associate of Freud's. They split up due to disagreements about the psychoanalytic theory. Jung's view on human nature was more positive than the one of Freud. He believed that human beings were trying to develop their potential and to control their instinctual urges. His idea of the collective unconscious, a storehouse of instincts, urges, and memories of the entire human species down through history, differs from Freud's believe in the personal unconscious, which based only of one's own instincts, urges and memories. Jung called these inherited, universal ideas archetypes. Every person has the same archetypes stored in the unconscious. Another student of Freud is Alfred Adler, who believed that feelings of inferiority, and the desire to overcome them were the main force in people's lives. He also introduced the term inferiority complex, the pattern of avoiding feelings of inadequacy and insignificance rather than trying to overcome their source. Additionally, Adler stessed the importance of the parental influence on the child, so that the child won't choose the wrong life style. Two theorists that didn't agree with Freud are Erich Fromm and Karen Horney. The need to belong and the loneliness freedom brings were the center of Fromm's theories. Basic anxiety and hostility caused by parents' resentment are the elements in Karen Horney's theory. She also didn't believe in Freud's theory of the penis envy in the development of women. Next to Jung and Adler are other theorists, who developed their own theories , basing them on Freud's or going in the opposite direction to proove him wrong. Erik Erikson agrees with Freud on the sexual and aggressive urges, but he believes that human have a need for social approval. He stated that development is a lifelong process with crisis on the way. His stages of psychosocial development each build on the last, which shows the transitions of life.
