= Grinstein 147; Norman Library F100: "In his analysis of group psychology, Freud examined the nature of the bonds that unite groups, which he traced back to the earliest example of group-formation, the family. He stressed the importance of the part played by the group leader, and stated that the ideal put forth by this leader must correspond with the ego ideal, or superego, of the group members."
