As explained in the Chapter on Causes, all of the physical organs which have to do with the production of speech and all of the brain centers whose duty it is to control the actions of these various organs, must operate in harmony, or, in other words, must coordinate, if we are to have perfect speech.  Co-ordination implies perfect mental control of physical actions.  And this in turn means perfect obedience of the physical organs of speech to the brain messages that are received.

The cure of stammering and stuttering requires a great deal of care based, of course, upon the correct scientific knowledge in the first place.

In attempting to cure stammering, there has been too much teaching by rigid rules and not enough teaching by principles.  There are very few hard-and-fast rules that can be followed with success by every stutterer or stammerer.  No set of rules can be laid down as a standard for every one to follow, for no two persons stammer exactly alike any more than two persons look exactly alike.

The only safe rule of all the rules is that which says, “Cleave closely to the principles, let the rules fall where they may.”  The only successful method is that which, being first based upon the right principle, is followed out with intelligence by the stammerer and administered with wisdom by the instructor to fit the needs and requirements of the individual case.

Methods necessarily three-fold:  The cure of stammering and stuttering can be wrought only by a method that is three-fold-that attacks all of the un-normal conditions of the stammerer simultaneously and eradicates them in unison.

It would be of little avail, for instance, to build up perfect breath control, and leave the stammerer in a mental state where he was continually harassed by a fear of failure, by a continual self-consciousness and irritated by a deep-seated nervousness.

And it would be of just as little use to try to remove that self-consciousness, fear of failure and nervousness without removing the cause of the stammering.

In other words, when the successful method of curing stammering is spoken of as being threefold in purpose, it is meant that this method must build up the physical being, must achieve perfect mental equilibrium and must link up the physical with the mental in perfect harmony.

A permanent cure can rest on no other foundation than perfect restoration to a truly normal mental and physical condition.  When this has been accomplished and when the synchronization of brain and speech organs has been brought about, the muscles of speech do not hesitate in responding to a brain message for the utterance of a word.  There is no longer any sticking, any loose or hurried repetition.  In other words, perfect speech now comes as a logical consequence.

Speech specialist should have stammered:  It is very important that the speech expert who would promulgate a method for the eradication of stammering should have, at one time or another, stammered himself.
