Watzlawick talked about applications of Math in Communication, like the Theory of Logical Types.
But there r rules in other sciences that r very applicable to Communication.
One example can be applying rules of Music to verbal communication, a Luxury Erickson could not afford, and a tool Ericksonians did not venture into.
Such applications of Music in Communication r the subject matter of Noesitherapy, a very fast and extremely effective tool of manipulating the Autonomous Nervous Syetem.
It seems like Ericksonians r all limping, just like Erickson himself. His limp was due to a defect, their limp id due to Ignorance.
Not mentioning that they (Ericksonians) have nothing to offer anymore...
