Identity and the Life Cycle by Erik H. Erikson, published in 1967, collects three early papers that many consider—along with Childhood and Society—the best introduction to Erikson’s theories on the relationship between life history and history. His remarkable insights began with observations on identity development in adolescence. “Ego Development and Historical Change” presents notes where Erikson first related observations on groups studied in field trips with children studied longitudinally and clinically. “Growth and Crises of the Healthy Personality” takes Erikson beyond adolescence into the critical stages of the whole life cycle. The third essay, “The Problem of Ego Identity,” deals with identity successively from biographical, clinical, and social points of view—all dimensions later pursued separately in his work.
Why it matters: Erikson’s framework for understanding how identity develops across the lifespan—not just in adolescence but through critical stages from infancy to old age—transformed psychology’s understanding of human development as a lifelong process shaped by both individual history and cultural context. By connecting ego development with historical change, Erikson showed that personal identity cannot be separated from the society and era in which it forms. These early papers reveal the source material and thinking that led to his influential stage theory, offering readers access to the foundations of ideas that continue to shape psychology, education, and our understanding of what it means to become who we are.
