In the craftsmanship of the classic presentation, the writer or speaker is taught to develop a problem and a proposition. I have modified the proposition to a promise, but I do not believe in a unilateral promise; I believe in a bilateral promise. I promise the audience something, but only if they do something in return. This forms an intellectual and spiritual contract. It is honest, because if they do not do their part, I cannot do mine. It also creates an understanding and a mutual expectation that powers the forward momentum of the presentation.
