The importance of considering our own minds will be seen when we realize that every new fact taken in must in a measure conform to the previous ideas. If some of these old ideas are erroneous, the mind must be more or less ready to discard them. It is very difficult to dislodge deep-seated convictions. Contradictory ideas are not assimilated. Only one of them is actually accepted. Even when to the objective reasoning they seem false, they frequently continue to control our actions.
Since we are loaded with the popular ideas which we have absorbed from our environment, it will be well for us to begin by critically examining our environment and the process by which ideas have been taken in. This may enable us to put out some of the erroneous views, and perhaps more firmly fix the true ideas; thereby preparing the mind for a more ready acceptance of what otherwise would be barred out as contradictory.
We shall not go deeply into the psychology of the subject, as it will not be necessary to go contrary to or beyond the well-known facts.
We shall not try to locate the man or refer to him as the ego or inner man. We shall simply say that we know that we can use our brains to think on any subject, and we can use our senses to collect information regarding any chosen subject.
Our senses and mental faculties can be directed to consider one element in a business, and for the moment be unmindful of the many other elements. In other words, we can to a certain extent manage our mental processes. Just as a horse can be managed, so may we manage our brains. A driver may carefully control the expenditure of energy and the course traveled, or he may throw the reins over the dash and allow the horse to go his own gait and route. In the same way we may manage or mismanage our brains.
Good Results with Moderate Effort.
A faster pace will not be advocated, for the present gait is overstrenuous. We hope, however, to point out a way by which good results may be obtained with, moderate effort.
If, in the past, the brain has been found wanting, we should not lose confidence in its reliability until we have seen how it has been managed.
Under some conditions its interpretations are absolutely correct; in fact, under all conditions that would be called fair in testing other kinds of mechanism.
Unfortunately, these conditions have not always existed. Opinions regarding important matters have been formed when accurate mentation has been impossible.
Physical Condition of Worker.
If the use of the machine induces either an adverse mental attitude or physical condition of the worker, it will sooner or later be adverse to the economic success of the machine.
We have indicated some of the problems and have suggested the well-known method of mental control for this purpose. A keen observer of men and machinery may not require as much of the so-called practical experience; another may need many years of actual work.
