"Total loyalty to the movement, which is the psychological basis for total domination, can be expected, Arendt contends, "only from the completely isolated human being" who does not have any social ties. In times of war, revolution, or economic crisis, these masses of isolated people become available for mobilization by totalitarian regimes. Membership... promises... a cure for their "loneliness" and feeling of "not belonging to the world..." The totalitarian propaganda offers "a lying world of consistency which is more adequate to [their] needs... than reality itself." Clinging to the ideology and propaganda of the... movement, these "uprooted masses" can feel at home "through sheer imagination." ...[I]n Arendt's conception of total domination, the subjects of this power move in two distinct circles: the wider circle... in society... members... prepared to provide total loyalty to the movement. The narrower circle... inmates of the concentration camps—the "laboratories" in which the experiment of total domination is fully realized."
