The importance of the study of the emotions in relation to human conduct is well understood. Just how consciousness behaves under the influence of the fundamental human emotions like fear and anger, is one of vital interest to the psychologist and educator. It has always been difficult to study the structural side of our emotions because of an inability to control voluntarily our emotions for purposes of introspection. The structure of emotions is primarily important in so far as structure may allow an interpretation of function. The study of the emotions has for the most part been limited to theoretical discussions based on the observations of normal and abnormal persons and on the casual introspection of individual authors. This work is an attempt to study systematically the emotion of anger in relation to the behavior of consciousness, the ideas and feelings associated in the development of anger, the reactive side of consciousness under the influence of anger, individual differences in behavior, manner of the disappearance and diminution of anger, devices used in the control and facilitation of the emotion, and the conscious after-effects including the inter-relation of anger and other feelings, emotions and attitudes which follow.

It is one of the complaints of the schoolmaster that the public does not defer to his professional opinion as completely as it does to that of practitioners in other professions. At first sight it might seem as though this indicated a defect either in the public or in the profession; and yet a wider view of the situation would suggest that such a conclusion is not a necessary one. The relations of education to the public are different from those of any other professional work. Education is a public business with us, in a sense that the protection and restoration of personal health or legal rights are not. To an extent characteristic of no other institution, save that of the state itself, the school has power to modify the social order. And under our political system, it is the right of each individual to have a voice in the making of social policies as, indeed, he has a vote in the determination of political affairs. If this be true, education is primarily a public business, and only secondarily a specialized vocation. The layman, then, will always have his right to some utterance on the operation of the public schools.
