What the great political thinker Hannah Arendt meant by totalitarianism was not an all-powerful state, but the erasure of the difference between private and public life. We are free only insofar as we exercise control over what people know about us, and in what circumstances they come to know it.

In The Origins of Totalitarianism, Hannah Arendt looked at the essential role that propaganda played in gaslighting the populations of Nazi Germany and Soviet Russia, writing that “in an ever-changing, incomprehensible world the masses had reached the point where they would, at the same time, believe everything and nothing, think that everything was possible and that nothing was true.”
“Mass propaganda,” she wrote, “discovered that its audience was ready at all times to believe the worst, no matter how absurd, and did not particularly object to being deceived because it held every statement to be a lie anyhow. The totalitarian mass leaders based their propaganda on the correct psychological assumption that, under such conditions, one could make people believe the most fantastic statements one day, and trust that if the next day they were given irrefutable proof of their falsehood, they would take refuge in cynicism; instead of deserting the leaders who had lied to them, they would protest that they had known all along that the statement was a lie and would admire the leaders for their superior tactical cleverness.

Totalitarianism is not only hell, but all the dream of paradise — the age-old dream of a world where everybody would live in harmony, united by a single common will and faith, without secrets from one another. Andre Breton, too, dreamed of this paradise when he talked about the glass house in which he longed to live. If totalitarianism did not exploit these archetypes, which are deep inside us all and rooted deep in all religions, it could never attract so many people, especially during the early phases of its existence. Once the dream of paradise starts to turn into reality, however, here and there people begin to crop up who stand in its way, and so the rulers of paradise must build a little gulag on the side of Eden. In the course of time this gulag grows ever bigger and more perfect, while the adjoining paradise gets even smaller and poorer.

The totalitarian systems warn of something far more serious than Western rationalism is willing to admit. They are, most of all, a convex mirror of the inevitable consequences of rationalism, a grotesquely magnified image of its own deep tendencies, an extreme offshoot of its own development, and an ominous product of its own expansion. They are a deeply informative reflection of its own crisis. Totalitarian regimes are not merely dangerous neighbors and even less some kind of an avant-garde of world progress. Alas, just the opposite: they are the avant-garde of a global crisis of this civilization, first European, then Euro-American, and ultimately global. They are one of the possible futurological studies of the Western world.

Secrecy begets tyranny.

Ultimately, totalitarianism is the only sort of politics that can truly serve the sky-god's purpose. Any movement of a liberal nature endangers his authority and that of his delegates on earth. One God, one King, one Pope, one master in the factory, one father-leader in the family at home.

Modern tyranny is terror management. When the terrorist attack comes, remember that authoritarians exploit such events in order to consolidate power. The sudden disaster that requires the end of checks and balances, the dissolution of opposition parties, the suspension of freedom of expression, the right to a fair trial, and so on, is the oldest trick in the Hitlerian book. Do not fall for it.

Totalitarianism is patriotism institutionalized.

If you pay attention, when you are seeking something, you will move towards your goal. More importantly, however, you will acquire the information that allows your goal itself to transform. A totalitarian never asks, “What if my current ambition is in error?” He treats it, instead, as the Absolute. It becomes his God, for all intents and purposes. It constitutes his highest value. It regulates his emotions and motivational states, and determines his thoughts. All people serve their ambition. In that matter, there are no atheists. There are only people who know, and don’t know, what God they serve.

"Once you admit that the individual is merely a means to serve the ends of the higher entity called society or the nation, most of those features of totalitarian regimes which horrify us follow of necessity. From the collectivist standpoint intolerance and brutal suppression of dissent, the complete disregard of the life and happiness of the individual, are essential and unavoidable consequences of this basic premise, and the collectivist can admit this and at the same time claim that his system is superior to one in which the "selfish" interests of the individual are allowed to obstruct the full realisation of the ends the community pursues."

The post-totalitarian system touches people at every step, but it does so with its ideological gloves on. This is why life in the system is so thoroughly permeated with hypocrisy and lies: government by bureaucracy is called popular government; the working class is enslaved in the name of the working class; the complete degradation of the individual is presented as his or her ultimate liberation; depriving people of information is called making it available; the use of power to manipulate is called the public control of power, and the arbitrary abuse of power is called observing the legal code; the repression of culture is called its development; the expansion of imperial influence is presented as support for the oppressed; the lack of free expression becomes the highest form of freedom; farcical elections become the highest form of democracy; banning independent thought becomes the most scientific of world views; military occupation becomes fraternal assistance. Because the regime is captive to its own lies, it must falsify everything. It falsifies the past. It falsifies the present, and it falsifies the future. It falsifies statistics. It pretends not to possess an omnipotent and unprincipled police apparatus. It pretends to respect human rights. It pretends to persecute no one. It pretends to fear nothing. It pretends to pretend nothing. Individuals need not believe all these mystifications, but they must behave as though they did, or they must at least tolerate them in silence, or get along well with those who work with them. For this reason, however, they must live within a lie. They need not accept the lie. It is enough for them to have accepted their life with it and in it. For by this very fact, individuals confirm the system, fulfil the system, make the system, are the system.

It has been the one song of those who thirst after absolute power that the interest of the state requires that its affairs should be conducted in secret... But the more such arguments disguise themselves under the mask of public welfare, the more oppressive is the slavery to which they will lead... Better that right counsels be known to enemies than that the evil secrets of tyrants should be concealed from the citizens. They who can treat secretly of the affairs of a nation have it absolutely under their authority; and as they plot against the enemy in time of war, so do they against the citizens in time of peace.

A totalitarian state is in effect a theocracy, and its ruling caste, in order to keep its position, has to be thought of as infallible. But since, in practice, no one is infallible, it is frequently necessary to rearrange past events in order to show that this or that mistake was not made, or that this or that imaginary triumph actually happened.

For the first time in my life, I was reading things which had not been approved by the Prophet's censors, and the impact on my mind was devastating. Sometimes I would glance over my shoulder to see who was watching me, frightened in spite of myself. I began to sense faintly that secrecy is the keystone of all tyranny. Not force, but secrecy...censorship. When any government, or any church for that matter, undertakes to say to it's subjects, This you may not read, this you must not see, this you are forbidden to know, the end result is tyranny and oppression, no matter how holy the motives. Mighty little force is needed to control a man whose mind has been hoodwinked, contrariwise, no amount of force can control a free man, a man whose mind is free. No, not the rack, not fission bombs, not anything — -you can't conquer a free man; the most you can do is kill him.
