This is a review of the psychosocial texts mentioned by Freud in his Group Psychology and analysis of the Ego. Its aim is to propose to the reader some knowledge of those texts that get lost in the time. Texts of Wilfred Trotter, William MacDougall, Gustave Le Bon and Gabriel Tarde are referred. Durkheim is also alluded, although he is not referred by Freud, but that reference allows to contrast a psychologically centered vision of the social phenomenon, which is the one of Freud and of the authors mentioned by him with a contribution in that the social is seen as independent of the psychological.
