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. Then, again, every major change in policy demands a corresponding change of doctrine and a revaluation of prominent historical figures.
