Robert Dilts has created the Sleight of Mouth, by modeling the power of persuasion of Socrates, Jesus of Nazareth, Karl Marx, Abraham Lincoln, Albert Einstein, Mahatma Gandhi, Martin Luther King, and others.
Robert Dilts writes about the Sleight of Mouth as follows:
I became convinced that these individuals were using some common, fundamental set of patterns in order to influence the beliefs of those around them. Furthermore, the patterns encoded in their words were still influencing and shaping history, even though these individuals had been dead for many years. Sleight of Mouth patterns are my attempt to encode some of the key linguistic mechanisms that these individuals used to effectively persuade others and to influence social beliefs and belief systems.
In our opinion, this point is the reason for the relentless focus on the issue. The power of influence and persuasion has always been valued and is valued now.
This reason explains the interest in learning and using the Sleight of Mouth. However, it accompanies with the interest in the change, elaboration, and structuring of SoM. This issue is the point to enlarge upon, having depicted the history of the Sleight of Mouth evolution to nowadays.
To do this, we will refer to the book by R. Dilts himself and show those places that were not systematized sufficiently by him but were elaborated afterwards.
