1909. In Part I of this volume, O'Shea attempts to describe the typical attitudes which the child tends to assume toward the persons with whom he comes into contact in the ordinary situations of daily life, and to explain these attitudes in view of certain fundamental principles of mental development. To this end the author has presented the results of observations of children's reactions under a variety of social conditions, the aim being to detect if possible the natural or impulsive tendencies in their responses. In Part II, O'Shea undertakes certain phases of the difficult and interminable task of outlining a plan and method of education designed to make the individual socially efficient.
