What are the motifs in Childhood and Society by Erik H. Erikson?

One of Erikson's stated goals in Childhood and Society is to unite Freudian psychoanalysis with cultural anthropology. Psychoanalysis involves an analysis of the individual and perhaps her relations to her parents or siblings. Cultural anthropology involves the study of cultures as a whole, their norms, customs, religious beliefs, and so on. Erikson tells a biological story that attempts to unite the two.
