The work of Freud has had an overwhelming impact on the development of twentieth-century social science. Its legacy is evident in contemporary psychology, sociology, anthropology, linguistics, literature, the arts, film and education. Its legacy is more than historical, and familiarity with the issues, methods and substantive content of Freudian psychoanalysis is indispensable for anyone with an interest in elucidating the human mind. Freud provides us with a language for understanding the person in everyday life, a language which is based on a total conception of the person and not some compartmentalised version of it. Perhaps this accounts for his appeal to both the academic and popular imagination.
