It is not the purpose of propaganda to create a series of alterations in sentiment with a view to pleasing these blase gentry. Its chief function is to convince the masses, whose slowness of understanding needs to be given time in order that they may absorb information; and only constant repetition will finally succeed in imprinting an idea on the memory of the crowd.

Every change that is made in the subject of a propagandist message must always emphasize the same conclusion. The leading slogan must of course be illustrated in many ways and from several angles, but in the end one must always return to the assertion of the same formula. In this way alone can propaganda be consistent and dynamic in its effects.
