The aim of modern propaganda is no longer to modify ideas, but to provoke action. — Jacques Ellul

The most favorable moment to seize a man and influence him is when he is alone in the mass. It is at this point that propaganda can be most effective.

In the midst of increasing mechanization and technological organization, propaganda is simply the means used to prevent these things from being felt as too oppressive and to persuade man to submit with good grace. When man will be fully adapted to this technological society, when he will end by obeying with enthusiasm, convinced of the excellence of what he is forced to do, the constraint of the organization will no longer be felt by him; the truth is, it will no longer be a constraint, and the police will have nothing to do. The civic and technological good will and the enthusiasm for the right social myths — both created by propaganda — will finally have solved the problem of man.

First of all, modern propaganda is based on scientific analyses of psychology and sociology. Step by step, the propagandist builds his techniques on the basis of his knowledge of man, his tendencies, his desires, his needs, his psychic mechanisms, his conditioning — and as much on social psychology as on depth psychology. He shapes his procedures on the basis of our knowledge of groups and their laws of formation and dissolution, of mass influences, and of environmental limitations. Without the scientific research of modern psychology and sociology there would be no propaganda, or rather we still would be in the primitive stages of propaganda that existed in the time of Pericles or Augustus.
