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.

The highest endowment of the human spirit on the intellectual side is the power to think. Learning to think is an essential process and end in all school work. Thinking is the intellect’s regal activity. In a vague way, all teaching appeals to the thought-activity of the pupil; but vagueness in teaching is as pernicious as it is common. To exhibit the value, scope, and process of thought is of inestimable service to the teacher. It gives specific direction to teaching processes, and saves the child from a thousand fanciful expedients.
