Harold Lasswell provided a broad definition of the term propaganda, writing it as: “the expression of opinions or actions carried out deliberately by individuals or groups with a view to influencing the opinions or actions of other individuals or groups for predetermined ends and through psychological manipulations.”[5]
Garth Jowett and Victoria O'Donnell theorize that propaganda is converted into persuasion, and that propagandists also use persuasive methods in the construction of their propagandist discourse. This theory signifies the similarity and optimization of propaganda using persuasive soft power techniques in the development and cultivation of propagandist materials.[6]
In a 1929 literary debate with Edward Bernays, Everett Dean Martin argues that, "Propaganda is making puppets of us. We are moved by hidden strings which the propagandist manipulates."[7]
Bernays acknowledged in his book Propaganda that "The conscious and intelligent manipulation of the organized habits and opinions of the masses is an important element in democratic society. Those who manipulate this unseen mechanism of society constitute an invisible government which is the true ruling power of our country. We are governed, our minds are molded, our tastes formed, our ideas suggested, largely by men we have never heard of."[8]"
