In a presentable way Adolph relays two areas of this book providing excellent detail and precise analysis of the issues. Propaganda is one issue. The text says it best:
The function of propaganda does not lie in the scientific training of the individual, but in calling the masses’ attention to certain facts, processes, necessities, etc., whose significance is thus for the first time placed within their field of vision.(page. 179)
The whole art consists of doing this so skillfully that everyone will be convinced that the fact is real, the process necessary, the necessity correct, etc. But since propaganda is not and cannot be the necessity itself, since its foundation, like the poster, consists in attracting the attention of the crowd, endnote in education those who are already educated or who are striving after education and knowledge, its effect for the most part must be aimed at the emotions and only a very limited degree at the so-called intellect.
All propaganda must be popular and its intellectual level must be adjusted to the most limited intelligence among those it is addressed to. Consequently, the greater the mass it is intended to reach, the lower its purely intellectual level will have to be…
The more modest its intellectual ballast, the more exclusively it takes into consideration the emotions of the masses, the more effective it will be…
The art of propaganda lies in understanding the emotional ideas of the great masses and finding, through a psychologically correct form, the way to the attention and thence to the heart of the broad masses.
The receptivity of the great masses is very limited, their intelligence is small, but their power of forgetting is enormous. In consequence of these facts, all effective propaganda must be limited to a very few points and must harp on those in slogans (page 180)
until the last member of the public understands what you want him to understand by your slogan. (page 181)
[T]he most brilliant propagandist technique will yield no success unless on fundamental principle is borne in mind constantly and with unflagging attention. It must confine itself to a few points and repeat them over and over. Here, as so often in this world, persistence is the first and most important requirement for success.(page 184)
…the masses are slow moving and they always require a certain time before they are ready, even to notice a thing, and only after the simplest ideas are repeated a thousand times will be masses finally remember them.
When there is a change, it must not alter the content of what the propaganda is driving at, but in the end must always say the same thing. …the slogan itself…(page 185)
Once the propaganda serves its purpose and a following and organization may ensue, propaganda continues as the primary means to communicate between the leadership and the little people. Adolph gives many paragraphs describing propaganda and its purposes (p. 580-596), but it is speculation. Adolph does not know how effective propaganda is. This book was written in 1924, four years before the Nazis had any sort of electoral success as a minority party. They never became a majority party by an election.
Adolph violates one of this primary rules here. He drifts into theory, mind-bending speculation about what might happen. The actual events in Germany from 1925-1933 differ widely from the theorems Adolph offers. At best he describes measures that may lead to a successful advertising campaign.
