Life is a serious of lessons and challenges which help us to grow. Erikson's wonderful theory helps to tell us why.
The theory is helpful for child development, and adults too.
For the 'lite' version, here's a quick diagram and summary. Extra details follow the initial overview.
For more information than appears on this page, read Erikson's books; he was an award-winning writer and this review does not convey the richness of Erikson's own explanations.

Erik Erikson first published his eight stage theory of human development in his 1950 book Childhood and Society. The chapter featuring the model was titled 'The Eight Ages of Man'. He expanded and refined his theory in later books and revisions, notably: Identity and the Life Cycle (1959); Insight and Responsibility (1964); The Life Cycle Completed: A Review (1982, revised 1996 by Joan Erikson); and Vital Involvement in Old Age (1989). Erikson's biography lists more books.
