5. "Squareness." This squareness is exemplified first of all by the attitude of the management. It provides, in every way, that the men are given a "square deal," in that the tasks assigned are of the proper size, and that the reward that is given is of the proper dimensions, and is assured. This has already been shown to be exemplified in many characteristics of Scientific Management, and more especially in the inspection and in the disciplining. MORAL DEVELOPMENT RESULTS IN CONTENTMENT, BROTHERHOOD AND THE "WILL TO DO".--The three results of this moral development are 1. contentment 2. brotherhood 3. a "will to do." 1. Contentment is the outgrowth of the personal responsibility, the appreciation of standing, and the general "squareness" of the entire plan of Scientific Management. 2. The idea of brotherhood is fostered particularly through the responsibility for others, through the feeling that grows up that each man is dependent upon all others, and that it is necessary for every man to train up another man to take his place before he can be advanced. Thus it comes about that the old caste life, which so often grew up under Traditional Management, becomes abolished, and there ensues a feeling that it is possible for any man to grow up into any other man's place. The tug-of-war attitude of the management and men is transformed into the attitude of a band of soldiers scaling a wall. Not only is the worker pulled up, but he is also forced up from the bottom.[4] 3. The "will to do" is so fostered by Scientific Management that not only is the worker given every incentive, but he, personally, becomes inspired with this great desire for activity, which is after all the best and finest thing that any system of work can give to him. INTERRELATION OF PHYSICAL, MENTAL AND MORAL DEVELOPMENT.--As to the interrelation of physical, mental and moral development, it must never be forgotten that the mind and the body must be studied together,[5] and that this is particularly true in considering the mind in management.[6] For the best results of the mind, the body must be cared for, and provided for, fully as much as must the mind, or the best results from the mind will not, and cannot, be obtained. Successful management must consider the results of all mental states upon the health, happiness and prosperity of the worker, and the quality, quantity and cost of the output. That is to say, unless the mind is kept in the right state, with the elimination of worry, the body cannot do its best work, and, in the same way, unless the body is kept up to the proper standard, the mind cannot develop. Therefore, a really good system of management must consider not only these things separately, but in their interrelation,--and this Scientific Management does.
