Freud: From Individual Psychology to Group Psychology, by M. Andrew Holowchak, explores Freudian psychoanalysis as a full-fledged science, as it relates psychoanalytically to issues of individual psychology (Individualpsychologie) and group psychology (Massenpsychologie). Holowchak analyzes Freud's shift in focus in his mature years away from psychoanalysis as a "curative" method for treating individual neurosis, to psychoanalysis as a full-fledged science of the human psyche that essays to shed light on group issues, such as religiosity and war.
