One thought drives away another; old facts are chased by new ones. Under these conditions there can be no thought. And, in fact, modern man does not think about current problems; he feels them. He reacts, but he does not understand them any more than he takes responsibility for them. He is even less capable of spotting any inconsistency between successive facts; man’s capacity to forget is unlimited. This is one of the most important and useful points for the propagandists, who can always be sure that a particular propaganda theme, statement, or event will be forgotten within a few weeks.
