In "Erik Erikson as Social Scientist," Neil J. Smelser, Ph.D., discusses Erikson’s role as a social scientist. Smelser emphasizes Erikson’s interdisciplinarian approach, some of the unresolved methodological issues in his approach, his diagnosis of Western culture, and his sociological idealism. Smelser, in a very concise and elegant critique, discusses in detail the strengths and weaknesses of Erikson’s approach as a social scientist, especially the difficulty in unifying or integrating into a whole Erikson’s multiple perspectives on human functioning and adaptation. In general, Smelser is quite positive about Erikson’s contributions, especially his discussion of the dangers of totalitarianism and the phenomenon of "pseudospeciation" and its detrimental effect on society.
