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 Herbart school adheres to this view of education, and has transferred its spirit and method to the schools. The Herbartians have the hardihood, in this age of moral skeptics, to believe not only in moral example but also in moral teaching. (By moral skeptics we mean those who believe in morals but not in moral instruction.) They seek first of all historical materials of the richest moral content, in vivid personification, upon which to nourish the moral spirit of children. If properly treated, this subject matter will soon win the children by its power over feeling and judgment. With Crusoe the child goes through every hardship and success; with Abraham he lives in tents, seeks pastures for his flocks, and generously marches out to the rescue of his kinsmen. He should not read Caesar with a slow and toilsome drag (parsing and construing) that would render a bright boy stupid. If he goes with Caesar at all, he must build an agger, fight battles, construct bridges, and approve or condemn Caesar’s acts. But we doubt the moral value of Caesar’s Gallic wars. By reading Plutarch we may see that the Latins and Greeks, before the days of their degeneracy, nourished their rising youth upon the traditions of their ancestry. The education produced a tough and sinewy brood of moral qualities.
