He was as strict a behaviorist as John Watson, and he sought only to determine how behavior is caused by external forces. He believed everything we do and are is shaped by our experience of punishment and reward. After nine years in Minnesota, and three years as head of the psychology department at the University of Indiana, Skinner returned to Harvard in 1948 as a professor and remained there for the rest of his career. In 1971 he wrote Beyond Freedom and Dignity which suggested the ceding of individual freedoms to further the goals of an ideal society. He died in 1990.
