In his text Mass Dictatorship and Modernist State, Roger Griffin explains that, according to Friedrich and Brezinski's text Totalitarian Dictatorship and Autocracy, Totalitarianism implies that freedom of speech and individualism be repressed, and mandates a uniform view of the world, but they also state that democratic programmes stem from totalitarian movements. It is stated that eventual purges, propaganda and other forms of terror are a necessity in order to get to a new stage which would be finalized by achieving a new society by the end in totalitarian regimes. This is the difference between them and authoritarian dictatorships, as they do not impose terror in order to achieve said new era, but rather only to exercise power over the masses. Authoritarian regimes also use totalitarian methods in order to appear legitimate, but are in fact reactionary. Essentially, authoritarian mass dictatorship represents a modern form of conservativism which seeks to restore "tradition" apparently without shattering liberal values that have been installed since the French revolution; as opposed to that, totalitarian mass dictatorship can be described as state trying to achieve modernity.
