The use of the Miltonmodel consists of stating many assertions. People recognize an assertion by the tone of voice. With an assertion there is no change in the tone of voice. This fact can be used to hide commands or questions by tonality. Asserting something leads to less critical reception by the unconsciousness of the other whereas arguments make the other more critical. The point of the use of the Miltonmodel is to lessen this critical reception.
Assertion safer than proof. – An assertion produces a stronger effect than an argument, at least among the majority of mankind: for argument arouses mistrust. That is why public speakers seek to hammer home their party’s arguments with assertions.
