It is one of the essential accomplishments of psychoanalysis that it has done away with the false distinction between social psychology and individual psychology.

Freud knew no homo psychologicus, no psychological Robinson Crusoe, like the economic man of classical economic theory. On the contrary, one of Freud’s most important discoveries was the understanding of the psychological development of the individual’s earliest social relations-those with his parents, brothers, and sisters.
