Goebbels' maxim can be stated as: the bigger the lie (and more it is stated with absolute conviction) the more people are likely to believe it.
Goebbels' maxim and Propagandists
Demagogues, dictators, and fanatical ideologists all try to convince audiences that their reasoning is logical and sound. In reality, they abuse logic, twist, slant, and distort the reasoning process in whatever ways they believe they can without detection. Some of these speakers believe that the bigger the misrepresentation they can get away with, the greater the triumph. Since propagandists have already made up their minds, they are not really searching for truth. Such people do not attempt to use logic in an honest search for truth, but only with the intent to deceive more effectively.
